admin: stop holding the shell admin lock across whole scheduler batches (#10290)
* admin: let waiting shell clients win the admin lock The admin lock manager re-acquired the cluster shell lock immediately after releasing it, while a waiting weed shell client only polls the master once a second, so an operator could lose the race indefinitely. Leave the lock free for slightly more than one poll interval before re-acquiring, and once overlapping reference-counted holds have kept the lock continuously held for over a minute, make new admin-side acquires wait for a full release before piggybacking. * admin/plugin: take the shell lock per detection and per job, not per batch The default-lane scheduler acquired the cluster shell lock once and held it across the whole pass: every due job type's detection plus all of its dispatched jobs, each drained to completion. A manual weed shell operation sharing that lock could stall behind the batch for up to the extended execution window. Hold the lock only while it protects something: around each detection scan and around each dispatched job. Manual shell operations now wait for at most one in-flight job. The admin UI detect+execute path stops wrapping dispatch in an outer hold, since a nested acquire would deadlock against the lock manager's fairness window; detection and per-job dispatch take the lock themselves. * admin/plugin: stop extending the dispatch window to the largest job estimate When any proposal's estimated runtime exceeded the remaining JobTypeMaxRuntime, the whole dispatch context was replaced with a fresh one capped at eight hours, so a single balance backlog could hold the default lane (and with it erasure_coding and vacuum detection) for that long. Keep the dispatch window at JobTypeMaxRuntime and instead detach each started attempt onto its own estimated-runtime deadline. Large jobs still get their full time once started; jobs not yet started when the window closes are canceled and re-proposed by a later detection, so sibling job types get a turn every window. * worker/balance: re-check each planned move against the master before executing A balance plan is computed at detection time, but the admin lock is released between detection and execution, so a manual shell operation can rearrange the volume in the gap. The task's own guards catch a vanished source, but a target that gained a replica in the meantime would be silently overwritten by VolumeCopy and the source delete would then reduce the volume to a single copy. Before executing each move, ask the master for the volume's current locations (uncached) and skip the move if the volume has left the source or the target already holds a replica. Skipped moves fail with a stale-move error and the next detection replans them. Without master addresses in the cluster context the check is skipped, preserving the old behavior with older admins. * admin: block re-acquire while the final lock release is in flight Release dropped the manager mutex before calling ReleaseLock, so a concurrent Acquire could see hold count zero and call RequestLock while the locker still considered itself locked. That request no-ops, leaving a hold with no live master lease. Track the in-flight release and make Acquire wait for it. Also normalize a nil release function from lock manager implementations, and make the yield and fairness windows per-instance fields so tests stop mutating globals. |

worker: project the moved volume when gating on disk fullness (#10171)
The disk-fullness gate only rejected destinations already at/above the mark, so a server just under it could take a large volume and overshoot. Project the selected volume's bytes onto the candidate: if the move would cross the mark, drop that destination for the rest of the cycle and re-pick instead of overshooting. Also note the per-location capacity-summing assumption on the Rust heartbeat side, to match the Go store.go comment. |

balance: share replica-placement logic between shell and worker (#10169)
The replica-placement rule (data-center/rack/same-node limits plus host anti-affinity) existed three times: the shell's satisfyReplicaPlacement/isGoodMove used by volume.balance, fix.replication, and tier.move, and a line-for-line port in the maintenance balance worker. Move the canonical logic into weed/topology/balancer on a shared Location type; the shell and worker keep thin adapters that convert their own location representation and call it. Behavior is unchanged (the shared IsGoodMove keeps the shell's reject-move-to-self guard, and all four replica test suites pass). |

ec: skip physically near-full disks when placing EC shards (#10167)
EC placement scored destinations purely by free EC shard slots (derived from maxVolumeCount) and shard counts, blind to real disk fullness — the same defect as volume balancing. A disk that is physically full but still shows free EC slots kept being chosen, and EC shard bytes are captured by statfs free space yet not by any slot accounting, so the slot math is exactly the metric that can't see EC fullness. Treat a disk at/above 90% physical usage as having zero free EC slots at snapshot-build time, so every existing freeSlots>0 placement predicate excludes it. Applied in all three snapshot builders (shell countFreeShardSlots, the shared ecbalancer FromActiveTopology, and the worker ec_balance buildBalancerTopology) via the shared balancer.DiskTooFullAfter gate. Servers not reporting disk bytes fall back to slot-only behavior. ec.rebuild recovery is left ungated so shard recovery can still complete onto fuller disks. |

volume.balance: gate on real physical disk usage (fixes #10160) (#10162)
* shell: add volume.balance -byDiskUsage to balance by actual data The default balancer ranks servers by slot density, dividing used volumes by MaxVolumeCount. When MaxVolumeCount is configured higher than the disk can hold, a physically near-full server looks nearly empty and gets picked as the move target, so balancing drains less-full servers onto an already-full one. -byDiskUsage ranks servers by the actual data they hold (sum of volume sizes) instead, so the fullest-by-data server is treated as full and balancing drains it. It assumes comparable disk sizes per disk type and still respects each server's free volume slots. Default behavior is unchanged. * plumb physical disk usage into topology, gate volume.balance on it Volume servers now report each disk's filesystem total/free bytes in the heartbeat, and the master stores them in DiskInfo. volume.balance uses them to skip any move target whose disk is already near full (-maxDiskUsagePercent, default 90), so an over-configured maxVolumeCount can no longer make a physically full server look empty and get drained onto. The gate judges each server against its own disk, so heterogeneous disk sizes are fine; servers that do not report bytes fall back to slot-only behavior. Rust seaweed-volume mirrors the heartbeat reporting. * admin: report real physical disk capacity when volume servers provide it The dashboard estimated server capacity as maxVolumeCount * volumeSizeLimit, which overstates it when maxVolumeCount is set higher than the disk holds. Prefer the filesystem capacity now reported per disk, falling back to the estimate for servers that do not report it. * worker: gate automatic balance on physical disk fullness too The maintenance balance worker selects the least slot-utilized server as the move destination, so an over-configured maxVolumeCount makes a physically full server look empty and get drained onto — the same defect as the shell command. Now that DiskInfo carries real disk bytes, skip any destination whose disk is at/above 90% used (per server, against its own disk); a full server can still be a source. When every candidate destination is full, create no tasks. Servers that do not report disk bytes are not gated. * balance: share the physical-disk-fullness gate between shell and worker The shell volume.balance command and the maintenance balance worker each grew their own copy of the disk-fullness gate (targetDiskTooFull / destinationDiskTooFull) and a maxDiskUsagePercent=90 constant. Pull both into weed/topology/balancer (DiskTooFullAfter + DefaultMaxDiskUsagePercent) so the policy has one home and the two balancers can't drift. * balance: harden the physical-disk gate Guard against a nil DiskInfo in the byte/slot lookups. Let a zero disk-capacity report clear previously stored bytes (0 means "not reported" for bytes, unlike maxVolumeCount), so a server that stops reporting falls back to slot-only instead of trusting stale capacity. In the worker, charge each planned move's bytes to its destination within a detection cycle so the gate sees a target fill up rather than only its heartbeat-time free space. Note the per-location capacity summing assumes one location per filesystem (the used ratio the gate relies on stays correct regardless; absolute capacity can over-report). |

worker: don't leak task goroutines on forced shutdown (#10062)
* worker: don't leak task goroutines on forced shutdown Stop() drains in-flight tasks for 30s, then terminates the manager loop. A task still running past that deadline later reports completion through w.cmds - getAdmin in completeTask, the ActionIncTask* send, removeTask - but with the loop gone and cmds unbuffered, those sends and the response reads behind getAdmin/getTaskLoad block forever, leaking the goroutine. Close a done channel when the loop exits and route the task-goroutine sends through it so they abort and return zero values instead of blocking. getAdmin can now return nil mid-shutdown, so collapse its double-call sites to a single nil-checked call to avoid a deref. * worker: abort remaining manager-loop sends after shutdown Extend the post-shutdown abort to the sends that still blocked: Stop()'s own ActionStop (so a second Stop, e.g. an admin-shutdown timer racing an explicit one, doesn't hang), setTask, and handleTaskCancellation. Route them through w.done so they return instead of blocking when the loop is gone. Stop is now idempotent. |

fix: use %w instead of %v in fmt.Errorf to preserve error chain (#10047)
In ec_task.go, 23 fmt.Errorf calls used %v verb to wrap errors, breaking the error chain introduced in Go 1.13. This prevents callers from using errors.Is() and errors.As() to inspect the underlying error type. Changed all fmt.Errorf calls from %v to %w to properly wrap errors, preserving the error chain for upstream callers. Note: glog.* logging calls and fmt.Sprintf calls intentionally keep %v as they are not error wrapping contexts. Co-authored-by: 吴奇臻 <wuqizhen@cmict.chinamobile.com> |

refactor(ec_balance): make the balance planner per-volume ratio-capable (#9960)
* refactor(ec_balance): make the balance planner per-volume ratio-capable Thread a per-volume EC ratio through the balance planner: Plan resolves each volume's data/parity from a new Options.VolumeRatio (falling back to the collection Ratio, then the build default, when it reports 0), and keys the global phase's ratio maps by volume instead of collection. The shell and worker balance paths build the per-volume lookup from each shard's heartbeat via the new ecbalancer.VolumeShardRatio. In OSS this is behavior-preserving: VolumeShardRatio returns 0 because the per-volume data_shards/parity_shards heartbeat fields are an enterprise feature, so every volume falls back to the collection ratio -- the existing standard-scheme behavior. The refactor keeps the shared planner in sync with the enterprise fork, which overrides VolumeShardRatio to classify and spread a mixed-ratio collection by each volume's own data/parity split. * perf(ec_balance): hoist the collection ratio out of the per-volume loop The collection ratio is constant for every volume in a collection, so resolve it once per collection instead of per volume; a custom Ratio func may do map lookups or locking. Addresses a review comment. |

fix(ec): fence stale-worker EC shard cleanup by encode generation (#9953)
* feat(ec): add encode_ts_ns to the EC task params, shard-unmount, and shard-delete RPCs The generation fence for stale EC-worker cleanup needs the encode generation on three messages: ErasureCodingTaskParams (admin issues it), VolumeEcShardsUnmountRequest, and VolumeEcShardsDeleteRequest (the worker carries it to the volume server). Additive fields only; 0 preserves the existing unfenced behavior. Mirror the two volume-server fields in the Rust volume server's proto copy. * feat(ec): issue the EC encode generation from the admin and carry it on the worker Stamp each EC proposal's encode_ts_ns from the admin's per-cycle DetectionSequence (a single-clock value) so generations are globally ordered even though detection runs on a rotating worker. The worker writes that generation into the distributed .vif and passes it on its shard unmount/delete RPCs; it falls back to a local timestamp for the .vif only on the unfenced legacy/shell path (keeping the read guard on). * fix(ec): fence the stale-worker EC shard unmount and teardown by generation A reaped-but-still-running EC worker's cleanupStaleEcShards issued a generation-blind unmount + full teardown that could unmount and then overwrite a newer run's live shards on a shared node. Both RPCs now carry the encode generation: the volume server unmounts/deletes a disk only when its .vif generation is strictly older than the request, and preserves a same-or-newer generation, a generation-0 (recovered or pre-upgrade) volume, and an unreadable .vif. Unload is per-disk, never node-wide. Request generation 0 keeps the blanket teardown for the shell pre-encode cleanup and pre-upgrade callers. Mirrored in the Rust volume server. * test(ec): cover the generation-fenced teardown and unmount End-to-end volume-server tests: a fenced FullTeardown wipes a strictly- older generation, preserves a newer one, preserves a generation-0 volume, and blanket-wipes on request generation 0; the gen-aware unmount preserves a same-or-newer mounted generation; and the .vif generation reader handles present/absent/no-config cases. * test(ec): pin the fenced .vif==teardown generation and the unreadable-.vif preserve A fenced run must stamp the admin generation verbatim into the .vif so it matches the generation sent on the teardown RPCs; add a regression test that sets the task generation and asserts the .vif carries it exactly. Also cover the present-but-unparseable .vif case (reads as generation 0, preserved) and correct the readEcGenerationTsNs docstring accordingly. * fix(ec): surface EC full-teardown filesystem errors in the Rust volume server remove_ec_volume_files(_full_teardown) discarded every fs::remove_file error, so a teardown that failed on permissions or a full disk still returned full_teardown_done=true and left stale artifacts to collide with the next encode. Return io::Result, ignore NotFound, propagate the first real error, and have the teardown RPC surface it -- matching the Go contract. The best-effort reconcile/load-cleanup callers keep ignoring it. * refactor(ec): reuse the EC volume lookup on unmount and short-circuit the gen read Address review: the Rust unmount fence reuses the ec_vol it already fetched instead of a second find_ec_volume; the Go .vif generation reader breaks out of the data/idx loop early when the two dirs are the same. |

fix(ec): group orphan-source completeness by encode generation (topology encode_ts_ns) (#9952)
* feat(ec): carry the encode generation through the topology heartbeat Add encode_ts_ns (field 14) to VolumeEcShardInformationMessage and populate it from each EC volume's .vif identity. The volume server emits it on the full and incremental heartbeats; the master stores it on EcVolumeInfo and re-emits it via GetTopologyInfo, so the admin/worker layer can see which encode run produced each shard set. Field 14 avoids the enterprise fork's reserved 10-13. Mirror the proto field and both heartbeat emit sites in the Rust volume server. * fix(ec): group orphan-source shard completeness by encode generation countExistingEcShardsForVolume ORed EcIndexBits across every disk, so two interrupted encode runs whose shard sets overlap unioned into a false-complete set -- triggering the orphaned-source delete while no single generation was actually complete. Group shards by encode_ts_ns and return the largest single generation's count, so the trigger fires only when one run holds the full set. Shards from pre-upgrade servers (encode_ts_ns==0) form their own bucket. The heartbeat carries one encode_ts_ns per (volume, disk), so this separates generations on different disks; same-disk mixing is prevented upstream by the pre-encode artifact wipe and the cross-run read guard. * fix(ec): guard against a nil Ec shard info entry in the generation count Defensive: a manually-constructed or corrupted topology could carry a nil entry in EcShardInfos. Skip it rather than dereference. * fix(ec): carry the encode generation on the EC shard unmount delta The mount delta sets EncodeTsNs; the unmount deletion delta left it 0. Populate it from the Ec volume before unloading so both incremental deltas are consistent (the Rust volume server already does this via its snapshot diff). |

fix(ec): persist EC source readonly mark and skip writable replicas on orphan cleanup (#9950)
* fix(ec): persist the EC source replica readonly mark markReplicasReadonly marked each regular replica readonly without persisting it, so a source-server restart during or after encoding silently reopened the volume to writes. Those writes are not in the EC shards, and the later orphan-source cleanup would then delete the replica, losing them. Send Persist:true so the mark survives a restart; rollbackReadonly still clears it via VolumeMarkWritable on a failed encode. * fix(ec): don't delete a writable source replica during orphan cleanup cleanupOrphanSourceReplicas issued VolumeDelete to every regular replica once the EC shard set looked complete, without checking the replica's current state. A replica that came back writable may hold writes the EC shards do not contain, so deleting it loses data. Re-probe each replica via VolumeStatus and skip any that is no longer readonly, logging a warning instead of deleting. |

fix(storage): never let an empty .dat delete healthy distributed EC shards (#9930)
* fix(storage): never let an empty .dat delete healthy distributed EC shards A leftover empty .dat stub (a phantom from the pre-fix loader; zero needles) next to a distributed EC volume's local shards made startup classify the volume as an interrupted local encode: validateEcVolume requires >= dataShards local shards when a .dat is present, fails with the 1-2 shards a distributed volume keeps per disk, and the cleanup deletes those shards -- the only copies of that part of the volume. Repeated across restart waves this destroys enough shards cluster-wide to make the volume unrecoverable. Go: - loadExistingVolume: hoist the empty-stub sweep above the EC presence checks. Previously the .vif-next-to-.ecx guard returned before the sweep ever ran, so exactly the dangerous layout (stub + .ecx + local shards) kept its stub and then lost its shards in loadAllEcShards. - validateEcVolume / checkDatFileExists: treat a .dat <= a superblock (zero needles) as absent. An empty .dat cannot be the encode source, so it must never gate shard deletion; this also covers stubs without a .vif, which the sweep cannot prove are EC leftovers. Rust mirror (seaweed-volume): the same gate in validate_ec_volume and check_dat_file_exists (the Rust sweep already ran before validation); the volume-load skip keeps a plain existence check so fresh, needle-less volumes still load. Regression tests in Go and Rust reproduce the production layout (a zero-byte .dat beside .ecx/.ecj and two shards of a 10+4 volume, with and without a .vif) and fail without the fix with the shards deleted. * fix(ec): gate source volume deletion on a recoverable shard set After EC encode, the shell command and the (plugin) worker task refused to delete the source volume unless every shard was present, and aborted otherwise -- leaving the source .dat next to live shards, exactly the mixed state the startup cleanup mishandles. Replace the full-set requirement with a recoverability gate shared by both callers (RequireRecoverableShardSet): deleting a non-empty source .dat requires at least dataShards distinct shards cluster-wide. Below that the source is kept and the encode fails as before. A degraded but recoverable set (>= dataShards, < total) now proceeds with a warning instead of aborting: the missing shards can be rebuilt from the survivors, while keeping the source would preserve the dangerous mixed state. Empty stub replicas are still swept unguarded (OnlyEmpty) -- an empty .dat has nothing to lose. dataShards/totalShards stay parameters so enterprise custom EC ratios share the helper verbatim. * test(ec): use recoverable shard verification gate |

admin: configure maintenance tasks via admin.toml (#9926)
* admin: configure maintenance tasks via admin.toml Maintenance task settings could only be edited in the admin UI and live under <dataDir>/conf, so they silently reverted to defaults whenever the data directory was recreated. An optional admin.toml now declares vacuum, balance, and erasure coding settings; keys set there are written through to the persisted task configs at every startup, overriding UI edits, so the configuration stays declarative. Generate an example with "weed scaffold -config=admin". * vacuum: round min volume age up to whole hours MinVolumeAgeSeconds was truncated by integer division when converted to the hour-granular protobuf field, so a sub-hour setting silently became 0 and disabled the age guard. * admin: split and normalize preferred_tags from admin.toml A comma-separated string, as set via environment variable, came through viper as a single slice element. Split on commas and reuse util.NormalizeTagList, matching the plugin config path. * scaffold: clarify admin.toml wording |

fix(tests): 32-bit build of EC e2e tests, type-check linux/386 in CI (#9922)
* fix(tests): keep EC e2e fid cookie arithmetic in uint32 The cookie constants 0x9490CA00 and 0x9500CA00 were added to the int loop variable before conversion, overflowing 32-bit int at compile time on linux/386 and linux/arm. Convert the loop variable instead so the addition stays in uint32. * fix(tests): pass s3client max backoff in milliseconds MaxBackoffDelay is documented as milliseconds and multiplied by 1e6 before use, but the example set it to 5s in nanoseconds, yielding an absurd backoff on 64-bit and a compile-time int overflow on 32-bit. * ci: type-check code and tests for linux/386 64-bit-only constant arithmetic keeps slipping into test files and breaking 32-bit downstream builds. Vet the whole root module under GOOS=linux GOARCH=386 so these fail in CI instead of after release. * fix(tests): convert s3client backoff to Duration before scaling The ms-to-ns multiplication ran in int, wrapping at runtime on 32-bit; scale by time.Millisecond after the Duration conversion instead. |

fix(ec): don't mix EC shards from different encode runs (#9880)
* feat(ec): add encode_ts_ns to EC shard metadata and the shard read RPC EcShardConfig and VolumeEcShardReadRequest gain an int64 encode_ts_ns (encode time in unix nanos). It rides in .vif and the read request so a read can be scoped to the encode run that produced the index. * fix(ec): stamp each encode and reject cross-run shard reads Generate stamps EncodeTsNs into the volume's .vif. Reads carry it to the shard's owning volume (resolved together via FindEcVolumeWithShard, so a multi-disk server validates the disk that actually serves the bytes) and reject a shard from a different encode run, recovering from parity. A zero on either side (pre-upgrade volume) skips the guard. * fix(ec): stamp the encode identity on the worker-generated .vif The worker-local encode path now writes EncodeTsNs (and the resolved EC ratio) into the .vif, so the read guard is not silently off for volumes encoded by the maintenance worker. * fix(ec): wipe stale EC artifacts before re-encoding VolumeEcShardsGenerate evicts any in-memory EcVolume for the volume and removes its on-disk shard/index/sidecar files before writing fresh ones, so a retried encode never builds on a partial prior run and the unlink frees the inodes instead of leaving open fds serving old bytes. * fix(ec): unmount EC shards across all disks UnmountEcShards walked only the first disk holding the shard, leaving a duplicate copy mounted on a sibling disk (split-disk reconciled volumes) still serving and heartbeating. Traverse every disk and emit one deletion delta per disk. * fix(ec): delete orphan shards without a local .ecx deleteEcShardIdsForEachLocation gated shard-file removal on a local .ecx, so it could not clean an orphan .ecNN left by a failed copy on a disk with no index. Delete the requested shard files unconditionally; the index-file (.ecx/.ecj/.vif) routing stays gated as before. * fix(ec): clear stale EC shards cluster-wide before re-encoding ec.encode unmounts and deletes EC shards for the target volumes on every node before regenerating: fatal for the shards the topology reports (mounted leftovers), best-effort for the rest (a sweep that catches unmounted failed-copy orphans). A down node is a no-op. * fix(ec): don't nil EC fds on close so reads can't race eviction A reader resolves an EcVolume/shard under the lock then reads after it is released, so an eviction that nils ecxFile/ecdFile would race that read and panic. Close the fds without nilling the fields: the field is now write-once (no data race) and a concurrent read hits a closed fd, getting a clean error that the caller recovers from parity. * fix(ec): wipe stale EC artifacts on every disk and surface failures The pre-encode wipe only deleted beside the source volume, so a stale shard on a sibling disk survived and could be mounted against the new index at reconcile. Sweep every disk. Removal also ignored os.Remove errors, reporting a failed cleanup as success and letting a stale shard join the next generation; surface the first real failure (treating already-gone as success) from removeStaleEcArtifacts and the shard delete. * fix(ec): log when a local shard is skipped for a different encode run The cross-run guard returned errShardNotLocal, indistinguishable in logs from a genuinely-absent shard. Add a V(1) line naming both EncodeTsNs so operators can tell "wrong encode generation" from "shard not here". * fix(ec): surface metadata removal failures in the shard delete path deleteEcShardIdsForEachLocation still dropped os.Remove errors on the .ecx/.ecj/.vif/sidecar cleanup. A surviving stale .ecx is the orphan-index condition this path prevents, so route those through removeFileIfExists and return the first real failure instead of reporting cleanup as success. * fix(ec): fail orphan cleanup when a reachable node's delete fails The pre-encode orphan sweep swallowed every error for unreported (node, volume) pairs. That is only safe for an unreachable node, which cannot receive this encode's new generation. A reachable node whose delete genuinely failed (permission/IO) keeps an orphan shard that a later copy re-stamps with the new run's volume-level .vif identity, so the read guard would accept stale data. Surface those; stay best-effort only for unreachable nodes (gRPC Unavailable / no status). * fix(ec): guard ecjFile under its lock in the EC delete path EcVolume.Close nils ecjFile under ecjFileAccessLock; a delete that resolved its .ecx lookup before a concurrent eviction (the generate-time UnloadEcVolume) could then reach the journal append with a nil fd. Bail with a clear "volume closed" error under the lock instead. * fix(ec): reject an unstamped shard when the caller has an encode identity The read guard required both identities nonzero, so a current (stamped) caller accepted a holder with identity 0 and could be served a stale pre-upgrade shard. Reject when the caller is stamped and the holder differs (including unstamped); stay lenient only when the caller itself has no identity (pre-upgrade reader). A skipped shard recovers from parity. * fix(ec): full-teardown delete so cluster cleanup wipes a whole generation The pre-encode cluster sweep deleted only the listed canonical shards on remote nodes, leaving index/sidecar (and, on builds with versioned generations, those too) behind. Add a full_teardown flag to VolumeEcShardsDelete that evicts the volume and wipes every EC artifact for it on every disk via removeStaleEcArtifacts; the shell and worker pre-encode cleanup paths set it. Other delete callers (balance/decode/repair) are unchanged. * fix(ec): take ecjFileAccessLock before the nil-check in Sync and Close Sync and Close read ev.ecjFile before acquiring ecjFileAccessLock while Close nils it under the lock, a data race on the field. Take the lock first, then nil-check inside, in both. * fix(ec): acknowledge full_teardown so a pre-upgrade server can't fake success An old volume server silently ignores full_teardown and returns success for an ordinary delete, so the caller wrongly believes the generation was wiped and copies a fresh gen-0 onto an unwiped node. Echo full_teardown_done in the response; the worker destination cleanup fails when it is absent, and the shell cluster sweep fails for a reported (mounted) leftover while staying best-effort for an unreported node. encode_ts_ns stays an accepted transient (an old server just skips the new read guard, no regression). * fix(ec): fail the pre-encode sweep for any reachable node that can't ack teardown A reachable pre-upgrade server ignores full_teardown and returns success without wiping an orphan, which a later copy then folds into the new generation. Treat a missing full_teardown_done ack as fatal for every reachable node (best-effort only for a gRPC-unreachable one), not just for topology-reported pairs. * fix(ec): return the served shard identity and validate it client-side The encode identity was only enforced server-side, so a pre-upgrade server ignored the request field and served bytes unchecked. Echo the served shard's EncodeTsNs on every read response chunk and have the client reject a mismatch (including 0 from an old server), so the guard holds regardless of server version; a rejected read recovers from parity. * fix(ec): reject a short/empty remote shard read instead of serving zeros doReadRemoteEcShardInterval accepted an immediate EOF or a short stream and returned success with a partly zero-filled, unvalidated buffer (the server stamps the identity only on chunks that carry bytes). A non-deleted interval must arrive whole: require n == len(buf), exempting the is_deleted short-circuit (n=0), matching readLocalEcShardInterval's local check. A short read now fails so the caller recovers from parity. * test(ec): fake volume server echoes the full_teardown acknowledgement The worker now fails a teardown delete that isn't acknowledged (so a pre-upgrade server can't silently skip the wipe). The fake server's no-op VolumeEcShardsDelete returned an empty response, which the worker read as a skipped teardown and aborted the encode. Echo full_teardown_done. * feat(ec): mirror the encode-run identity guard + full_teardown into the Rust volume server The Go volume server stamps an encode-run identity (encode_ts_ns) into the .vif and rejects a read served from a shard of a different run; full_teardown wipes a whole generation and acknowledges it. The Rust volume server had none of it. Mirror the shared logic: load encode_ts_ns from the .vif onto the EcVolume, stamp it on every read response, and reject a request/response mismatch on both the server and the distributed-read client (recovering from parity); handle full_teardown by evicting the volume and wiping every EC artifact on each disk, echoing full_teardown_done so the caller can detect a server that ignored it. * fix(ec): remove a stale .vif on full teardown of a shard-only node A shard copy installs shards + .ecx before .vif, so an interrupted copy after a teardown could mount the new files under the previous run's identity / version / shard ratio / dat_file_size carried by the surviving .vif. Remove .vif during full teardown, gated on .idx absence so a source-volume holder keeps its live .vif. In Rust this lives in a teardown-only helper so the reconcile / load- fallback paths (which share the base removal) still preserve .vif. * fix(ec): treat a missing teardown ack as fatal, not as an unreachable node isNodeUnreachable returned true for any non-gRPC-status error, so a reachable pre-upgrade server's missing full_teardown_done ack (a plain error) was classified unreachable and the unreported pair was silently skipped. Classify only a real codes.Unavailable as unreachable, and wrap the missing ack in a sentinel the sweep treats as fatal regardless. A genuinely down node still surfaces as Unavailable from the RPC and stays best-effort. * fix(ec): reject a short shard read in the local EC needle reader read_ec_shard_needle ignored the byte count from shard.read_at and appended the whole pre-sized buffer, so a truncated shard's zero-filled tail passed the later length check and parsed as garbage. Require n == buf.len() per interval, erroring on a short read like the local interval reader already does. * fix(ec): probe reachability before skipping a node that returns Unavailable The pre-encode sweep skipped any node whose teardown delete returned codes.Unavailable, but a reachable volume server in maintenance mode also returns that code for the maintenance-gated delete, so its stale EC files were left behind on a node that can still receive the new generation. Confirm with a non-maintenance-gated empty-target Ping: skip only when the node fails the probe too (genuinely unreachable). * fix(ec): use try_exists for the teardown .vif .idx guard The teardown-only .vif removal gated on Path::exists(), which returns false on a permission/IO stat error, so a stat failure on a present .idx would read as a shard-only node and delete the live source volume's .vif. Gate on try_exists() == Ok(false) instead, preserving the sidecar on any stat error. * fix(ec): only skip a sweep node when a Ping confirms it is transport-down The pre-encode sweep skipped a node whenever its teardown delete and a liveness Ping both failed, but it treated ANY Ping error as down — an application-level Internal/ResourceExhausted, or Unimplemented from a pre-Ping server, left a reachable node's stale generation in place. Classify the Ping tri-state and skip only when it transport-fails with codes.Unavailable; a reachable or inconclusive node stays fatal. * fix(ec): exclude sweep-skipped nodes from the encode's rebalance The pre-encode sweep skips a genuinely-down node best-effort, but the rebalance then recollected the current topology — a node that recovered between the two could become a copy target and receive the new generation while still holding its stale, never-cleared shards. Have the sweep return the skipped set and exclude those nodes from the rebalance for this encode, so a node we could not clean cannot receive the new generation. Standalone ec.balance is unaffected. * fix(ec): re-sweep recovered nodes before generation so they aren't stranded A node skipped as down by the pre-encode sweep is excluded from the rebalance, but it can recover and become the generation host — mounting all shards locally, then being excluded from distribution. Union-only verification accepts all shards on one node and deletes the originals: a single point of failure. Re-sweep the skipped nodes just before generation; one whose teardown now succeeds leaves the skipped set and rebalances normally, while a node still down stays skipped. * fix(ec): abort the encode if a selected source is still skipped after re-sweep The re-sweep un-skips a recovered node, but the source was selected before it and a node can stay down through the re-sweep then recover just in time to be the generation host — mounting all shards locally while still excluded from the rebalance, which union-only verification accepts before deleting the originals. Abort the encode when a selected source remains skipped after the re-sweep. * fix(ec): batch delete returns retriable 503 when a volume became EC mid-batch If a volume is not EC at the batch-delete classification but is encoded to EC and its .dat deleted before the regular-volume mutation, the mutation returns an exact "not found" that the filer chunk-GC treats as completed, dropping the delete. Recheck EC presence under the mutation lock and return a retriable 503 with the "try again" token so the filer requeues it onto the EC path. * fix(ec): recheck EC state before the regular batch-delete mutation ec.encode mounts EC shards (copied from the .dat) before deleting the originals, so a volume can be EC while its .dat still exists. The batch delete only rechecked EC after a NotFound, so a successful regular-volume delete in that window wrote a tombstone to the soon-removed .dat — the delete was lost and the needle resurrected from the pre-tombstone shards. Recheck has_ec_volume under the write lock before delete_volume_needle and return a retriable 503 so the filer requeues onto the EC path. * fix(volume): make the metrics push test independent of test order test_push_metrics_once asserted the pushed body contains the request-counter family without ever touching the counter — a CounterVec with no children emits nothing, so the assertion only held when another test had already created a labelset in the shared registry. Create one in the test itself. |

ec.balance: verify shard landed on destination before deleting the source (#9858)
* ec.balance: verify shard(s) landed on the destination before deleting source The EC balance task copied/mounted a shard to the destination and then immediately unmounted+deleted it from the source, reporting success as soon as the RPCs returned. A copy/mount can return OK while the shard isn't actually registered/loadable on the destination, so deleting the source then loses the shard (and the scanner re-issues the same move every cycle). Add a verification step (VolumeEcShardsInfo via VerifyShardsAcrossServers, the same check the EC encode task uses before deleting originals): if the destination doesn't report every moved shard, fail the task and keep the source so the move is retried instead of losing data. * address review: use comma-ok when reading destination shard inventory |

Treat co-located volume servers as one fault domain when balancing and allocating (#9854)
* admin/topology: carry the volume server address on DiskInfo The planning DiskInfo exposed only the node id, which can be an opaque label rather than ip:port. Record the address too so callers can resolve the physical machine a disk sits on. * ec.balance: spread a volume's shards across machines, not just nodes Volume servers sharing a host are one fault domain, but the within-rack spread treated them as independent nodes, so one box could end up holding more shards of a volume than EC can afford to lose. Add a machine (host) tier between rack and node: the within-rack pass spreads each volume across machines, and the global load phase no longer re-concentrates a volume onto a machine it already sits on. Host defaults to the node id, so clusters with one server per host are unchanged. * ec placement: prefer machines holding fewer of a volume's shards EC allocation and repair picked the least-loaded node in a rack with no regard for which physical machine it sits on, so a volume's shards could pile onto several servers of one box. Rank candidate nodes by their machine's shard count first, then the node's own. The machine is derived from the volume server address carried on DiskInfo, falling back to the node id, matching how the balancer resolves it. * volume.balance: don't move a replica onto a machine already holding one isGoodMove only rejected a move onto the same data node, so two replicas could land on two volume servers of one box and a single machine failure would lose both. Reject a target whose host already holds another replica of the volume. Best-effort: balancing simply skips and tries the next target. * volume allocation: spread same-rack replicas across machines PickNodesByWeight filled the same-rack replica picks by weight alone, so replicas could co-locate on one box. Prefer candidates on not-yet-used hosts, falling back when too few distinct machines exist. Data-center and rack tiers have no host, so their ordering is unchanged. * ec.balance: harden machine spread against re-concentration and capped machines Two cases where the machine-aware spread could still leave a volume badly placed: - The global load phase could move a shard of a volume onto a machine that already held it, raising that machine's count and undoing the within-rack spread (a 4/4/3/3 layout could become 3/5/3/3, past parity for 10+4). Limit the load-only fallback to same-machine moves, which leave a machine's count unchanged; cross-machine concentration is no longer allowed for load alone. - The within-rack spread chose a destination machine by free slots alone, so if that machine's only nodes were already at the SameRackCount cap it skipped the move instead of trying another machine. Require a machine to have a node that can actually take the shard before selecting it. * reduce comments across the machine-affinity change Trim narration down to the non-obvious why; one terse line where a block was overkill. * ec.balance: gate machine spread on fault-tolerance feasibility Spreading a volume evenly across machines only helps when there are enough that each can stay within EC's parity tolerance (numMachines >= ceil(total/parity)). With fewer -- or wildly unequal -- machines it can't make a machine loss survivable anyway, and forcing it fights capacity: e.g. a cluster of 12 volume servers on one host and 2 on another would have half of every volume crammed onto the 2-server box. So spread across machines only when it's achievable; otherwise fall back to per-node spread and let capacity/global balancing decide. The global load phase applies the same test: it protects a volume's machine spread (no cross-machine move that raises a machine's count past the source's) only where that spread is achievable, so heterogeneous clusters still level by fullness. * ec.balance worker: group servers by host when planning The worker built its planner topology without recording each server's host, so automated ec.balance treated ports on one machine as independent nodes and could concentrate a volume's shards on one physical box. Set the host from the volume server address, matching the shell path. * volume.balance worker: don't move a replica onto a machine holding one The worker compared only node ids, and the replica map dropped the server address, so it could move replicas onto different ports of one machine. Carry the host on ReplicaLocation (from the server address) and reject a target whose host already holds another replica of the volume. Best-effort, matching the shell. * ec.balance: judge machine-spread feasibility by the rack's shards The within-rack and global feasibility checks compared the whole volume's shard count against a rack's machine count, so a rack holding only part of a volume after cross-rack spreading -- e.g. 7 of a 10+4 volume across 2 machines -- was wrongly judged infeasible and fell back to node spread, which could pile 6 shards onto one host, past parity. Gate on the rack's own shard count of the volume instead. * ec.balance: spread a volume's shards across machines by combined count EC recovers from any loss within parity regardless of shard type, so what bounds a machine's exposure is its total shards of the volume, not data and parity separately. Spreading the two independently let each type's remainder land on the same machine -- ceil(d/M)+ceil(p/M) can exceed ceil(total/M), e.g. a 5/3 split where 4/4 was achievable, past parity. Balance the combined count in one pass; disk-level data/parity anti-affinity stays in pickBestDiskOnNode. * ec.balance: don't let the imbalance threshold skip an over-parity machine The within-rack spread gated on relative skew ((max-min)/avg > threshold), so a worker threshold of 0.5 skipped an exactly-50%-skewed layout like 5/4/3 for a 10+4 volume, leaving 5 shards -- past parity -- on one machine. The even cap (ceil(shards/groups)) is the real bound and the move loop already sheds only what exceeds it, so drop the threshold gate from the within-rack phase (machine and node): a balanced rack stays a no-op while any over-cap machine is always fixed. * ec.balance: keep the imbalance threshold for the node fallback Dropping the threshold from the whole within-rack phase made the node fallback too eager: it runs only when machine fault tolerance is unachievable, so it is cosmetic load distribution that should defer to the global utilization phase. Without the gate it would, for a one-server-per-host 6/4 split at threshold 0.5, schedule a count move that worsens utilization balance. Restore the threshold there; machine spreading keeps bypassing it, since that bound is durability, not cosmetic skew. |

fix(ec): pass per-volume data-shard count to the parity-shard split (#9781)
* fix(ec): pass per-volume data-shard count to the parity-shard split ShardsInfo.DeleteParityShards/MinusParityShards looped ids 10..13, assuming the fixed 10+4 layout. For a non-default ratio this splits data vs parity wrong — a wide ratio (12+4, 16+6) drops real data ids >= 10, which breaks ec.decode. They now take a dataShards argument (<= 0 falls back to DataShardsCount) and clear ids dataShards..MaxShardCount. ec.decode threads the data-shard count from collectEcNodeShardsInfo to both split call sites, and admin LogicalSize passes DataShardsCount. Also: EC cleanup now sets an explicit per-disk storage impact (-len(ShardIds)) instead of falling back to the TotalShardsCount constant, so freed-capacity accounting matches the shards actually removed. OSS is always 10+4, so behavior is unchanged here; this keeps the split ratio-correct and the API aligned with the enterprise per-volume override. Adds parity-split ratio tests. * ec: clear parity shards in one locked pass Address review: DeleteParityShards looped si.Delete, taking the lock once per id. shards is sorted by Id and shardBits is a bitmap, so mask off the high bits and truncate the sorted slice at the first parity id (binary search) under a single lock. Preserves the dataShards<=0 -> DataShardsCount default. |

EC bitrot detection: per-shard checksum sidecars (#9761)
* ec: add EC bitrot checksum protobuf EcBitrotProtection/EcShardChecksums/ChecksumAlgorithm sidecar messages, copy_ecsum_file and unsafe_ignore_sidecar fields, and a CHECKSUM scrub mode. * ec: bitrot checksum sidecar format, validation, and per-volume load Per-shard CRC32C block checksums in an optional <base>.ecsum sidecar with a self-integrity header; validation, rolling builder, backfill primitive, and EcVolume load on mount + removal on destroy. * ec: capture per-shard checksums at encode; verify-and-exclude on rebuild WriteEcFilesWithContext returns the protection computed inline during encoding. generateMissingEcFiles verifies present inputs against the sidecar, excludes corrupt ones, regenerates in place, and re-verifies; fail-closed unless unsafe_ignore_sidecar, removing all generated outputs on failure. * ec: read-only checksum scrub with Reed-Solomon arbiter ChecksumScrub verifies each local shard against the sidecar and reconstructs flagged shards from the clean shards so stale-sidecar false positives are not reported. Wired to the gRPC CHECKSUM mode and ec.scrub -mode checksum. * ec: server-side bitrot sidecar write, copy, cleanup, and opportunistic backfill Write .ecsum at fresh encode; propagate it with copy_ecsum_file (tolerant); remove it on full delete and decode; rebuild honors unsafe_ignore_sidecar and opportunistically backfills a sidecar when all shards are reachable. * ec: volume server bitrot config flags -ec.bitrotChecksum (default on) and -ec.bitrotBlockSizeMB (default 16). * fix(ec_bitrot): bound -ec.bitrotBlockSizeMB before the int64 multiply Validate the MiB value is in [1, 1024] before multiplying by 1 MiB, so a huge flag value cannot overflow int64 and slip past the power-of-two check, and a block size cannot collapse a sidecar to a few oversized blocks. * fix(ec_bitrot): distribute the .ecsum sidecar from the worker encode path The worker EC encode wrote the generation-0 sidecar locally but never added it to shardFiles, so DistributeEcShards never shipped it and the distributed holders came up unprotected. Append it to shardFiles and map the ecsum shard type to its extension in the sender so it travels with the shards. * fix(ec_bitrot): remove orphaned sidecars when the generation is gone Gate sidecar removal on existingShardCount==0 alone rather than also requiring a stray .ecx. A sidecar whose shards have all been deleted is orphaned and must be removed even when no .ecx remains, or it leaks. .ecx/.ecj/.vif removal stays gated on hasEcxFile as before. * fix(ec_bitrot): do not fold checksum blocks scanned into TotalFiles ChecksumScrub's first return is blocks scanned, not files. Discard it so the scrub response's TotalFiles (a needle/file count) is not inflated by the block count for CHECKSUM mode. * test(ec_bitrot): clean up generated .ecsum sidecars in removeGeneratedFiles * fix(ec_bitrot): reject an oversized sidecar payload before the uint32 cast The header stores payload_len as a uint32; bound the payload before the conversion so a pathological manifest cannot truncate the length field and corrupt the sidecar. A real manifest is a few KB, so this never trips. * fix(ec_bitrot): cap -ec.bitrotBlockSizeMB at 64 MiB The block size becomes the per-shard scratch buffer the scrub/backfill path allocates, so an over-large value (e.g. 1 GiB) is a memory hazard per concurrent scrub worker. Lower the upper bound from 1024 to 64 MiB. * fix(ec_bitrot): add -ecUnsafeIgnoreSidecar to weed tool fix -ecx The -ecx recovery path reconstructs missing shards via RebuildEcFilesWithContext, which fails closed on a malformed/stale .ecsum. Without an override flag an operator could not complete the rebuild without manually deleting the sidecar. Expose -ecUnsafeIgnoreSidecar (default false) and thread it through. * fix(ec_bitrot): bound sidecar payload with a direct int constant; drop readFull Guard len(payload) against a plain int constant (1 GiB) before the allocation instead of a uint64 MaxUint32 compare, so the allocation-size value is provably bounded (clears the CodeQL overflow alert) and the math import is no longer needed. Inline os.File.ReadAt with io.EOF handling in verifyShardFileBlocks and remove the now-redundant readFull helper (os.File.ReadAt fills the slice or errors). * test(ec_bitrot): use slices.Contains instead of a hand-rolled containsU32 * refactor(ec): fold the EcFiles WithContext variants into the base functions RebuildEcFiles now takes the *ECContext directly (nil => derive from .vif as before) and WriteEcFiles takes it too (nil => default), removing the parallel RebuildEcFilesWithContext / WriteEcFilesWithContext names. Callers that had an explicit context drop the WithContext suffix; the default-context callers pass nil. No behavior change. * refactor(ec): pass BackgroundECContext instead of nil to Write/RebuildEcFiles Add a non-nil BackgroundECContext placeholder (analogous to context.Background()) and have callers with no specific layout pass it instead of a nil *ECContext. WriteEcFiles resolves a zero/background context to the default ratio and RebuildEcFiles resolves it from the .vif, so behavior is unchanged. * fix(ec_bitrot): make BackgroundECContext a func; RebuildEcFiles fails closed on bad .vif - BackgroundECContext is now a function returning a fresh *ECContext, so callers cannot mutate a shared singleton or race on it (and it mirrors context.Background, which is also a function). - RebuildEcFiles now propagates the MaybeLoadVolumeInfo error: a present-but- unreadable .vif fails closed instead of silently rebuilding with the default ratio (which would corrupt a custom-ratio volume). Pass an explicit ctx to override. |

fix(vacuum): writable volume re-notification after worker VACUUM (#9732)
* fix(vacuum): notify master writable after worker vacuum commit Add Phase 3 (markWritableOne) that walks vacuumTargets and calls VolumeMarkWritable on each replica's volume server, mirroring batchVacuumVolumeCommit's per-replica SetVolumeAvailable. Failures are logged at WARN; the task does not fail because the vacuum itself already succeeded. See upstream seaweedfs#9685. * fix(vacuum): delay Phase 3 to let post-commit heartbeats settle Phase 3's VolumeMarkWritable can race with the volume server's first post-commit heartbeat. SetVolumeWritable adds the vid to writables, but a racing heartbeat whose ReadOnly value changed re-runs EnsureCorrectWritables against the master's per-replica cache, and any replica still cached as ReadOnly=true silently removes the vid again — with no further heartbeat change to trigger another recovery. Sleep 30s after Phase 2 (Commit) so every replica's post-vacuum heartbeat has reached the master before Phase 3 fires. Cancel cleanly on ctx.Done so a shutdown during the wait still exits. * fix(vacuum): reduce post-commit settle from 30s to 10s VolumePulsePeriod is 5s, so 10s (2x) is enough margin for every replica's post-commit heartbeat to reach the master before Phase 3 fires. 30s was overly conservative and made TestVacuumExecutionIntegration hit its 30s context deadline. * fix(vacuum): use flat 1m timeout for VolumeMarkWritable RPC VolumeMarkWritable on the volume server is a metadata operation (reopen idx + flags + master ReadOnly=false heartbeat), independent of volume size. Scaling via vacuumTimeout(time.Minute) gave it tens of minutes — even hours on TB volumes — so a single unresponsive replica could block Phase 3 indefinitely. Use a flat 1m cap. * fix(vacuum): gate post-vacuum mark-writable on commit read-only state Phase 3 force-called VolumeMarkWritable on every replica unconditionally, clearing the read-only flag and persisting ReadOnly=false even for a replica left read-only by an operator, an EIO quarantine, or low disk. That overrode states the master deliberately keeps out of writables; master built-in vacuum gates the same step on the commit's IsReadOnly via SetVolumeAvailable. Capture the VacuumVolumeCommit response and skip Phase 3 when any replica came back read-only, letting it recover on its own ReadOnly=false heartbeat. Drop the 10s post-commit settle sleep: the heartbeat race it guarded needed a replica cached read-only at the master, which the gate now excludes. --------- Co-authored-by: Chris Lu <chris.lu@gmail.com> |

test(ec): end-to-end encode over a multi-server multi-disk stuck layout (#9728)
* test(framework): support multiple disks per server in MultiVolumeCluster StartMultiVolumeClusterWithDisks gives each volume server N data directories (one DiskLocation each), passed to -dir as a comma list, with a per-server disk-dir accessor for file inspection. StartMultiVolumeCluster keeps its one-disk default. * test(ec): end-to-end encode over a multi-server multi-disk stuck layout A volume in the stuck state — real .dat source, a 0-byte stub replica, and partial stale EC shards from an interrupted encode — must converge to one valid EC layout. Asserts the full shard set across servers, .ecx/.vif kept per server (info file survives the source-volume delete), stale shards cleared, and no regular .dat/.idx left behind. |

fix(storage): keep EC .vif when deleting a coexisting regular volume (#9723)
* fix(storage): keep EC .vif when deleting a coexisting regular volume A regular volume and an EC volume for the same id share <base>.vif. When EC shards are distributed onto a server that still holds the regular volume — the encode source, or any replica the planner targets — the post-encode VolumeDelete ran removeVolumeFiles and stripped the shared .vif, leaving the freshly built EC volume without its info file. Skip the .vif in removeVolumeFiles when an EC volume for the same id exists on the disk (mounted, or a sealed .ecx on disk). The regular volume's .dat/.idx still go; the EC sidecars survive. A two-server end-to-end test encodes a volume whose source and a stub replica both also receive shards, and asserts the final on-disk layout: both .dat/.idx gone, each server holding only its assigned shards plus .ecx/.vif. Storage unit tests cover the with-EC and no-EC cases, and the Rust seaweed-volume port carries the same guard and tests. * test(storage): assert .idx is removed in the no-EC destroy case Strengthen TestDestroyRemovesVifWhenNoEc to confirm the full regular volume cleanup (.dat, .idx, .vif) when no EC volume coexists. |

fix(ec): delete empty stub replicas before distributing EC shards (#9722)
* fix(ec): delete empty stub replicas before distributing EC shards An interrupted encode can leave a 0-byte .dat replica behind. Until now the only thing that removed it was deleteOriginalVolume, which runs after distribute+mount and calls VolumeDelete -> removeVolumeFiles. A regular volume and an EC volume share the same <collection>_<vid>.vif path, so deleting the stub at that point strips the .vif out from under the freshly distributed shards. Sweep the original replicas with VolumeDelete(OnlyEmpty=true) before distribute: doIsEmpty uses the same superblock threshold, so only the 0-byte stubs go and any data-bearing replica is refused and kept for the post-verify delete. Servers cleared in the sweep are skipped by deleteOriginalVolume so it never touches a server that now holds only EC shards. * fix(ec): fail the encode when an empty-replica sweep can't confirm a node The sweep swallowed every VolumeDelete(OnlyEmpty) error, so a transient failure on a stub node fell through to the post-verify force-delete on that node — the shared-.vif clobber the sweep exists to avoid. Treat only the expected cases (volume not empty, or already gone) as leave-in-place; any other error propagates and fails the encode, which rolls back the readonly marks and retries next cycle. |

fix(ec): prefer credible replica as canonical metric in EC detection (#9717)
* fix(ec): prefer credible replica as canonical metric in EC detection An interrupted encode can leave a 0-byte .dat replica behind. When that stub sits on a lower-sorting server than the real replica, the lowest-server canonical pick reported Size=0, tripped the min-size gate, and the volume was stranded in skippedTooSmall: detection never proposed an encode, so the partial EC shards were never cleared and re-distribute kept hitting the mounted-volume guard. selectCanonicalMetric now prefers the lowest-server credible replica (data-bearing, not already EC), falling back to the lowest-server metric only when nothing is credible so the downstream gates skip as before. A leftover EC shard set on a lower server no longer short-circuits the volume at the IsECVolume guard either, so the orphan-source cleanup and re-encode paths get their chance. * fix(ec): treat a bare superblock .dat as a stub too An interrupted encode or copy can write the 8-byte superblock and then fail, leaving an 8-byte .dat with no data. isStubReplica used a strict < so that file slipped through as credible, could win the canonical pick on a low server, and re-tripped the min-size gate. Use <= the superblock so a data-less .dat never shadows a real replica. |

fix(vacuum): batch all replicas in a single plugin worker task (#9702)
* fix(vacuum): batch all replicas in a single plugin worker task The plugin worker vacuum path emitted one TaskDetectionResult per (volume, server) replica, but the dispatcher gates duplicate tasks per volume via ActiveTopology.HasAnyTask. The first replica's task was created and the remaining N-1 replicas were silently dropped, so only one replica per volume was ever vacuumed — leaving the others with all their garbage intact. Mirror the master built-in flow (topology.vacuumOneVolumeId → batchVacuumVolumeCheck/Compact/Commit/Cleanup) by: - aggregating detection metrics by VolumeID so a single task carries every replica in TaskParams.Sources - having VacuumTask accept []string servers (instead of a single string), re-check each replica's garbage ratio at execute time to derive a vacuumTargets subset, and run Compact/Commit/Cleanup against only that subset - updating the dispatcher (plugin_handler.Execute, register.CreateTask) to forward every Sources node to NewVacuumTask * fix(vacuum): run all-replica vacuum in two phases to keep failure atomic The prior implementation iterated Compact → Commit → Cleanup against each replica in sequence. A Compact failure on the second replica left the first one already committed (its active files swapped with the .cp* files), producing replica divergence with no automatic recovery. Split performVacuum into two phases, matching topology.vacuumOneVolumeId: Phase 1 — Compact all targets. If any fails, run VacuumVolumeCleanup on every target to drop the .cpd/.cpx/.cpldb temp files, then abort. No replica has swapped yet, so every replica returns to its original state. Phase 2 — Commit all targets. Best-effort, matching batchVacuumVolumeCommit: per-replica errors are collected and surfaced together. Once any replica has swapped there is no clean rollback, so a partial Phase 2 failure requires operator reconciliation. Adds compactOne / commitOne / cleanupOne / cleanupAll helpers and removes the old performVacuumOne. * fix(vacuum): abort when any replica's garbage check fails The prior check tolerated per-replica RPC errors and only failed the task if every replica errored — partial failures were silently treated as "ineligible" so the responding replicas would still be vacuumed. That produces divergence the moment the unreachable replica comes back: it still carries the original garbage while the others have been compacted. Match topology.batchVacuumVolumeCheck's contract instead — its return value (errCount == 0 && len(vacuumLocationList.list) > 0) gates the whole vacuum on every replica's check succeeding. If any replica is unreachable or its VacuumVolumeCheck RPC errors, abort the task; the volume will be retried on the next detection cycle once the replica is healthy. * fix(vacuum): guard against nil metrics and TaskSource entries Detection's bucket-building loop dereferenced m.VolumeID without checking m for nil. VacuumTask.Validate built sourceSet from params.Sources without checking each entry for nil. Both paths would panic on a malformed protobuf payload that managed to deliver a nil slot. Skip nil entries in both loops — neutral with the existing nil/empty filtering already done in register.CreateTask and plugin_handler.Execute. * test(vacuum): success path no longer calls VacuumVolumeCleanup The plugin worker vacuum is now two-phase (Compact-all → Commit-all, with Cleanup only invoked on Compact failure to roll back .cp* temp files). This matches topology.vacuumOneVolumeId, where batchVacuumVolumeCleanup runs only on the Compact-failure branch. On a successful Commit the temp files do not linger: - CommitCompactVolume renames .cpd → .dat and .cpx → .idx - leveldb needle map renames .cpldb → .ldb (needle_map_leveldb.go) so calling VacuumVolumeCleanup afterwards is a redundant no-op. The prior worker code called it unconditionally and the integration test asserted that — switch the expectation to cleanupCalls == 0 to document the new (and master-aligned) contract. |

EC detection: build placement snapshot once per cycle (fix large-topology timeout) (#9625)
* EC detection: build placement snapshot once per cycle, not per volume planECDestinations rebuilt the full ecbalancer snapshot (FromActiveTopology) for every eligible volume, and resolved each shard destination's address via ResolveServerAddress, which rebuilds the whole node map on every call. Both are O(volumes x topology) and made detection time out on large clusters (TestErasureCodingDetectionLargeTopology: 300k volumes hit the 2-minute deadline). Build the snapshot and the node-address map once per detection cycle and pass them in. planECDestinations now reserves the shards it assigns directly into the shared snapshot, so volumes planned later in the same cycle still see the reduced capacity (previously this was observed by rebuilding from ActiveTopology's pending tasks). Large-topology detection drops from a 120s timeout to ~3.5s. * Update weed/worker/tasks/erasure_coding/detection.go Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> --------- Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> |

Delete the EC placement package now that encode/repair use ecbalancer.Place (#9624)
Delete the EC placement package and the dead encode planner code Now that encode (and repair) place via ecbalancer.Place, nothing uses the erasure_coding/placement package or the EC-only planner machinery (ecPlacementPlanner, diskInfosToCandidates, calculateECScoreCandidate, distributeECShards) in detection.go. Removes them and the package, along with the planner-direct unit tests. |

EC encode: place shards via ecbalancer.Place + configurable replica placement (#9623)
* Add shared super_block.ResolveReplicaPlacement; use it in ec_balance
* Add ecbalancer.FromActiveTopology snapshot constructor for EC encode/repair
* Add ecbalancer.Place greenfield/repair placement core (strict + durability-first)
* topology: add GetEffectiveAvailableEcShardSlots; FromActiveTopology uses shard-granular free slots
GetDisksWithEffectiveCapacity flattens reserved shard slots into volume slots via
integer truncation, so an in-flight EC task reserving a non-multiple-of-
DataShardsCount number of shards was lost from the snapshot and freeSlots was
over-reported. GetEffectiveAvailableEcShardSlots subtracts the full reservation
impact at shard granularity.
* ecbalancer.Place: reject nodes without a free disk of the requested type
FromActiveTopology keeps all disk types in the snapshot, so an SSD-only request
could be routed to a node with only HDD capacity (pickBestDiskOnNode then returns
disk 0 on the wrong tier). Filter rack/node selection to those with a free disk
of the requested type.
* ecbalancer.Place: enforce ReplicaPlacement DiffDataCenterCount (per-DC shard cap)
* ecbalancer: enforce DiffDataCenterCount in balance (cross-DC phase + cross-rack DC cap)
Adds a cross-DC corrective phase that drains data centers holding more than
DiffDataCenterCount shards of a volume, and a per-DC cap on cross-rack move
targets. Both are no-ops when DiffDataCenterCount is unset, so balance output is
unchanged for non-DC placements.
* topology: ratio-aware EC shard slots and provisional empty-disk slot
GetEffectiveAvailableEcShardSlots now takes the target collection's data-shard
count, so a 4+2 volume's larger shards are not over-counted at 10 per volume slot;
and it keeps the one provisional slot for freshly started empty servers that
report max=0, matching getEffectiveAvailableCapacityUnsafe. FromActiveTopology
threads the ratio through.
* ecbalancer.Place: explicit disk-type filter signal (fix HDD vs any ambiguity)
HardDriveType normalizes to "", which collided with "" meaning any disk. Add
Constraints.FilterDiskType and normalize both sides so a hdd request matches disks
reported as "" and never leaks to SSD, while filter=false still means any.
* ecbalancer: add clearShardAccounting for repair snapshot reconciliation
Clears one disk's copy of a shard from per-domain accounting and recomputes the
node-level union (preserving a kept copy on another disk of the same node), without
crediting capacity. Repair uses it to drop to-be-deleted copies before placing
missing shards.
* ecbalancer: don't cap cross-DC target racks when DiffRackCount is unset
len(racks)+1 wrongly limited each target rack (3 in a 2-rack cluster), so draining
a DC could stop short of the DiffDataCenterCount cap. Use MaxShardCount+1 as the
effectively-unlimited default.
* topology/ecbalancer: ratio-correct EC capacity accounting
Reservation shard slots (default ShardsPerVolumeSlot units) are now converted to
the target ratio before subtracting, and existing EC shards are charged by size
(targetDataShards/shardDataShards) so a 2+1 shard isn't counted as one 10+4 slot.
Per-shard ratio lookup is behind shardDataShards (OSS uses the standard ratio).
* ecbalancer.Place: candidate tiering and eligible-rack caps
Adds a per-disk eligibility/preference abstraction so Place supports:
- preferred-tag whole-plan retry (try disks carrying the earliest tags first,
widen to all only if a tier cannot place every shard; reports
SpilledOutsidePreferredTags),
- soft disk-type spill via DiskTypePolicy (Any/Prefer/Require): Prefer fills the
preferred type then spills, reporting SpilledToOtherDiskType; Require filters,
- even per-rack caps that divide by racks holding an eligible disk, so a tiered
cluster (e.g. SSDs in 2 of 4 racks) isn't capped impossibly low.
Disk tags carried via Node.AddDiskTags + FromActiveTopology.
* ecbalancer: export ClearShardAccounting for repair snapshot reconciliation
* ecbalancer: address review feedback (ratio rounding, bitmap walk, same-DC moves)
- topology/ecbalancer: round shard-reservation and existing-shard footprint up
when converting to target-ratio shard slots, so a sub-slot reservation is not
truncated to zero and free capacity is not overstated for low-data-shard
layouts (targetDataShards < ds).
- erasure_coding: add ShardBits.All iterator and use it across the balancer,
cross-DC phase, and placement scoring instead of scanning 0..MaxShardCount and
probing Has on every id.
- ecbalancer: allow same-DC cross-rack moves when a DC already sits at its
DiffDataCenterCount cap; a same-DC move leaves the DC total unchanged. Add a
regression test that fails without the guard.
- ecbalancer cross-DC phase: pick targets via the eligible-aware
pickNodeInRackEligible/pickBestDiskEligible helpers so the disk-type filter is
honored and a 0 disk id is not mistaken for a valid selection.
* ecbalancer: test ecShardSlotsOnDisk fractional round-up
Cover the mixed-ratio path (targetDataShards < existing data shards) so a
shard's fractional footprint is never floored to zero and free capacity is not
overstated. Exercises the round-up via the targetDataShards parameter; OSS uses
the standard ratio at runtime while the enterprise build hits it with real
per-volume ratios.
* ecbalancer: assert node B rack in TestFromActiveTopology
* ecbalancer: split Destination into separate DataCenter and bare Rack
Replace the composite "dc:rack" Rack field on Destination with separate
DataCenter and bare Rack values, matching topology.DiskInfo and the worker-task
convention. Callers (and tests) read the data center directly instead of parsing
the composite with strings.SplitN.
* shell ec.balance: use utilization-based global balancing (parity with worker)
The shell's global rebalance phase balanced by raw shard count; switch it to
fractional fullness (shards/capacity), as the worker already does. On uniform
capacity the two agree; on heterogeneous capacity it fills nodes proportionally
instead of driving small-capacity nodes toward full.
Updates the heterogeneous-capacity regression test to assert even fullness
(~equal shards/capacity per node) rather than even shard count.
* ecbalancer: bounded-proportional per-DC shard spread
DiffDataCenterCount was enforced only as a ceiling (drain-to-cap), which could
leave a within-cap-but-lopsided DC distribution under a loose cap (e.g. 10/4 of 14
with cap=10). Now the cross-DC phase, the cross-rack DC guard, and Place all target
boundedMaxPerDC = min(DiffDataCenterCount, max(ceil(total/numDCs), parityShards)):
shards spread proportionally across DCs, but no tighter than the durability floor
(once each DC holds <= parityShards a DC loss is recoverable, so further spreading
only adds cross-DC/WAN traffic). No-op when DiffDataCenterCount is 0; identical to
before when the cap is the binding constraint.
* ecbalancer: drop DiffDataCenterCount enforcement for EC placement
The 1-byte volume ReplicaPlacement packs xyz into x*100+y*10+z<=255, so the DC
digit can only be 0-2 -- far too small to be a meaningful per-DC EC shard cap (a
cap of 1-2 would demand 7-14 DCs for a 10+4 volume). It's volume replica-placement,
not an EC spec. Removes the cross-DC balance phase, the DC guard in the cross-rack
phase, and the per-DC cap in Place (and the just-added bounded-proportional logic);
EC relies on the RP-independent rack/node even spread instead. Rack/node caps
(DiffRackCount/SameRackCount) are unchanged. Per-domain EC caps are left for a real
EC placement spec.
* ecbalancer: enforce per-disk durability cap; symmetric reserve/release
Place now refuses to put more than parityShards shards of a volume on a single
disk (pickBestDiskEligible skips a disk once it holds parityShards of the volume,
a hard cap not relaxed even in durability-first). Previously Place assigned by
free capacity, so a skewed near-full cluster could pile >parityShards onto one
disk -> losing it loses the volume; only distinct-disk count was checked. This
covers encode and repair (both route through Place); the caller skips/leaves the
volume rather than minting an unrecoverable layout.
Also makes reserveShard decrement freeSlots unconditionally, symmetric with
releaseShard's unconditional increment (the old guarded decrement could credit a
phantom slot on release if a shard were ever reserved onto a full disk).
* ecbalancer: add Topology.ReleaseVolumeShards (clear + credit) for greenfield encode
Releases all of a volume's shards from the snapshot and credits the freed disk
capacity, so a greenfield encode can plan as if stale EC shards from a prior failed
attempt are gone. Safe to credit because the encode task deletes stale shards
(cleanupStaleEcShards) before distributing the new ones. Distinct from
ClearShardAccounting (repair), which does not credit.
* ecbalancer: ReleaseVolumeShards credits node freeSlots, not just disks
releaseShard only increments per-disk freeSlots, but rack capacity is summed from
node freeSlots (buildRacks) and node freeSlots gates node eligibility. Crediting
only disks left a node/rack looking full after releasing stale shards, so a
greenfield encode still couldn't use the freed capacity. Now credits the node by
the total disk-slots freed.
* ecbalancer: correct PlacementMode docs (encode uses durability-first)
PlaceStrict was labeled '(encode)' but encode uses PlaceDurabilityFirst. Clarify
that durability-first is used by both encode and repair, reports relaxations in
PlaceResult.Relaxed, and never relaxes the per-disk durability cap.
* ecbalancer: treat SameRackCount as a direct per-node shard cap
The 3rd ReplicaPlacement digit now caps shards per node at exactly the digit
value, matching how DiffRackCount (2nd digit) caps per rack, instead of allowing
digit+1 per node. This makes the per-rack and per-node caps consistent and
matches the documented "digits cap EC shards per rack and per node" semantics;
e.g. 011 now means at most one shard per rack and one per node.
* EC encode: place shards via ecbalancer.Place + configurable replica placement
Encode now plans destinations through the shared ecbalancer.Place policy
(durability-first: prefers the source disk type and honors replica placement /
caps / anti-affinity, relaxing rather than failing when capacity is tight) instead
of the EC-only placement planner. Targets and capacity reservations use Place's
actual per-disk shard assignment, not a round-robin guess; cross-volume in-cycle
capacity is tracked by ActiveTopology's pending task, so the cached planner is no
longer consulted. Adds a configurable replica_placement (proto field 6 + worker
form + reader) that overrides the master default replication.
The placement-package planner code is left in place (now unused) and removed in a
follow-up that drops the package.
* EC encode: drop unused dataShards param from createECTargets
Addresses review feedback: after switching to Place's per-disk shardsPerPlan
assignment, createECTargets no longer needs the data-shard count.
* EC encode: fix packed-target validation, greenfield stale-shard accounting, RP docs
- Validate counts distinct shard ids across targets, not target rows, so packed
plans (fewer (node,disk) targets than shards) aren't rejected.
- planECDestinations releases the volume's stale EC shards from the snapshot before
Place (ReleaseVolumeShards), crediting their capacity. The encode task deletes
stale shards before distributing, so a retry on tight capacity no longer fails
planning by counting shards that are about to be removed.
- replica_placement config/form help no longer claims a data-center limit (the DC
digit is ignored for EC); detection logs a warning when a DC digit is set.
* EC encode: surface relaxed placement; mark replica_placement best-effort
Encode places with PlaceDurabilityFirst (the chosen lenient behavior), which can
relax caps/anti-affinity/replica-placement to avoid deferring. That was silent
(only disk-type/tag spills were logged). Now logs PlaceResult.Relaxed so a tight
replica placement isn't weakened unnoticed, and the config/form help states the
rack/node caps are best-effort during encode (enforced by rebalancing).
* EC encode: key per-disk shard grouping by struct, not formatted string
planECDestinations grouped destinations using a fmt.Sprintf("%s:%d") map key
per shard; use a {node,diskID} struct key and pre-size the map/slice to the
shard count to drop the per-shard string allocation.

fix(ec): log EC destination planning failures at v=2

fix(ec): bring ec.encode worker and EC/volume helpers to parity with shell (#9599)
* refactor(volume): extract replica sync/select into shared volume_replica package Move the volume replica reconciliation helpers (status, union builder, SyncAndSelectBestReplica, ReadNeedleMeta) out of the shell into a new weed/storage/volume_replica package so both the shell (ec.encode, volume.tier.move, volume.check.disk) and the EC encode worker can reuse them. No behavior change. * fix(ec): bring ec.encode worker to parity with the shell - Sync replicas and encode the most-complete one (via the shared volume_replica.SyncAndSelectBestReplica) instead of a possibly-stale replica, marking all replicas readonly first. Prevents silent data loss when a stale replica is encoded and the originals deleted. - Skip remote/tiered volumes in detection (shell ec.encode excludes them). - Min-node safety gate: refuse to encode when cluster nodes < parity shards. - Align default thresholds with the shell (fullness 0.95, quiet 1h). * fix(vacuum): plugin path honors min_volume_age_seconds override deriveVacuumConfig hard-coded MinVolumeAgeSeconds=0, dropping any configured value. Read it from worker config (default 0, matching the shell/master vacuum which has no age gate) so an explicit override is honored. * address review feedback - config.go: align GetConfigSpec schema defaults (quiet_for_seconds=3600, fullness_ratio=0.95) with the runtime defaults so UI/bootstrap flows match the shell (coderabbitai). - ec_task.go: roll back readonly when markReplicasReadonly fails partway, so already-marked replicas don't stay readonly (coderabbitai). - volume_replica: pass the caller's replica statuses into buildUnionReplica instead of re-fetching them, and skip the per-needle ReadNeedleMeta RPC when the source replica is read-only (gemini-code-assist). * test(plugin_workers/ec): make fixtures eligible under the new defaults The default EC encode thresholds were raised to match the shell (fullness 0.95, quiet 1h), but the plugin-worker integration fixtures still used 90%-full / 10-minute-old volumes, so detection found no eligible volumes and the tests failed in CI. Bump the eligible fixtures to 96% full and 2h old. |

fix(admin): carry filer addresses as ServerAddress in plugin cluster context (#9600)
The plugin cluster context forwarded filers as gRPC-only addresses (host:grpcPort). The admin-script worker stored that in ShellOptions.FilerAddress, whose shell commands re-derive the gRPC port via ToGrpcAddress() and re-add the +10000 offset, dialing a non-existent host:28888. Carry filers in pb.ServerAddress form (host:httpPort.grpcPort) and let each consumer convert when it dials: the admin shell uses it verbatim, while the s3_lifecycle and iceberg workers collapse it to a gRPC address. Rename the proto field filer_grpc_addresses -> filer_addresses so the name matches the content. |

fix(ec): correct multi-disk disk counting and EC balance shard attribution (#9594)
* fix(shell): count physical disks in cluster.status on multi-disk nodes
The master keys DataNodeInfo.DiskInfos by disk type, so several same-type
physical disks on one node collapse into a single DiskInfo entry. cluster.status
(printClusterInfo) and CountTopologyResources counted len(DiskInfos), reporting
one disk per node instead of the real physical disk count, while volume.list and
the admin ActiveTopology already split per physical disk.
Route both counters through DiskInfo.SplitByPhysicalDisk so a node with N
same-type disks reports N. Cosmetic/diagnostic only; placement already uses the
per-disk activeDisk map.
* fix(ec): attribute EC balance source disk per shard and reject same-node moves
On multi-disk nodes the EC balance worker built a node-level view that kept only
the first physical disk id per (node, volume), so a move of a shard living on a
different disk reported the wrong source disk. That source disk drives the
per-disk capacity reservation, so the wrong disk drifts the capacity model the
EC placement planner relies on. Track shards per physical disk and resolve the
actual source disk for every emitted move (dedup, cross-rack, within-rack,
global), keeping the per-disk view consistent as simulated moves are applied.
Also close a data-loss trap: VolumeEcShardsDelete is node-wide (it removes the
shard from every disk on the node) and copyAndMountShard skips the copy when
source and target addresses match, so a same-node move would erase a shard it
never copied. isDedupPhase now requires the same node AND disk, and Validate /
Execute reject same-node cross-disk moves outright.
* fix(ec): spread EC balance moves across destination disks
Port the shell ec.balance pickBestDiskOnNode heuristic to the EC balance
worker so a moved shard is placed on a good physical disk instead of always
deferring to the volume server (target disk 0). The detection now builds a
per-physical-disk view of each node (free slots split from the node total, exact
EC shard count, disk type, discovered from both regular volumes and EC shards)
and, for each cross-rack, within-rack, and global move, chooses the destination
disk by ascending score:
- fewer total EC shards on the disk,
- far fewer shards of the same volume on the disk (spread a volume's shards
across disks for fault tolerance), and
- data/parity anti-affinity (a data shard avoids disks holding the volume's
parity shards and vice versa).
Planned placements are reserved on the in-memory model during a run so multiple
shards moved to the same node spread across its disks rather than piling on one.
* fix(ec): bring EC balance worker to parity with shell ec.balance
The worker's cross-rack and within-rack balancing balanced shards by total
count; the shell balances data and parity shards separately with anti-affinity
and honors replica placement. Port that logic so the automatic balancer makes
the same fault-tolerance-aware decisions as the manual command:
- Cross-rack and within-rack now run a two-pass balance: data shards spread
first, then parity shards spread while avoiding racks/nodes that already hold
the volume's data shards (anti-affinity), mirroring doBalanceEcShardsAcrossRacks
and doBalanceEcShardsWithinOneRack.
- Optional replica placement: a new replica_placement config (e.g. "020")
constrains shards per rack (DiffRackCount) and per node (SameRackCount); empty
keeps the previous even-spread behavior.
- The data/parity boundary is resolved from a per-collection EC ratio (standard
10+4 here), replacing the previously hardcoded constant at the call sites.
Selection is deterministic (sorted keys) to keep behavior reproducible.
* refactor(ec): extract shared ecbalancer package for shell and worker
The EC shard balancing policy was duplicated between the shell ec.balance
command and the admin EC balance worker, and the two had drifted (multi-disk
handling, data/parity anti-affinity, replica placement). Extract the policy into
a new pure package, weed/storage/erasure_coding/ecbalancer, that both callers
share so it cannot drift again.
- ecbalancer.Plan(topology, options) runs the full policy (dedup, cross-rack and
within-rack data/parity two-pass with anti-affinity, global per-rack balance,
and diversity-aware disk selection) over a caller-built Topology snapshot and
returns the shard Moves. It depends only on erasure_coding and super_block.
- The worker builds the Topology from the master topology and turns Moves into
task proposals; the shell builds it from its EcNode model and executes Moves
via the existing move/delete RPCs. Per-collection EC ratio resolution stays in
each caller (passed as Options.Ratio).
- Options expose the two genuine policy differences: GlobalUtilizationBased
(worker balances by fractional fullness; shell by raw count) and
GlobalMaxMovesPerRack (worker moves incrementally across cycles; shell drains
in one pass).
The shell keeps pickBestDiskOnNode for the evacuate command. Policy tests move to
the ecbalancer package; the shell and worker keep their adapter/execution tests.
* fix(ec): restore parallelism and per-type/full-range balancing after ecbalancer refactor
Address regressions and gaps from the ecbalancer extraction:
- Shell ec.balance honors -maxParallelization again: planned moves run phase by
phase (preserving cross-phase dependencies) with bounded concurrency within a
phase. Apply mode does only the RPCs concurrently; dry-run stays sequential and
updates the in-memory model for inspection.
- Rack and node balancing gate on per-type spread (data and parity separately)
instead of combined totals, so a data/parity skew is corrected even when the
per-rack/node totals are even.
- Global rack balancing iterates the full shard-id space (MaxShardCount) so
custom EC ratios with more than the standard total are candidates.
- Cross-rack planning decrements the destination node's free slots per planned
move, so limited-capacity targets are no longer over-planned.
* fix(ec): make EC dedup keeper deterministic and capacity-aware
When a shard is duplicated across nodes, keep the copy on the node with the most
free slots and delete the duplicates from the more-constrained nodes, relieving
capacity pressure where it is tightest. Tie-break on node id so the choice is
deterministic. This unifies the shell and worker (the shell previously kept the
least-free node, an incidental default) on the more sensible behavior.
* fix(ec): restore global volume-diversity and per-volume move serialization
Two more behaviors lost in the ecbalancer refactor:
- Global rack balancing again prefers moving a shard of a volume the destination
does not hold at all before adding another shard of an already-present volume
(two-pass, mirroring the old balanceEcRack), keeping each volume's shards
spread across nodes.
- Shell apply-mode execution serializes a single volume's moves within a phase
while still running different volumes in parallel, so concurrent moves of the
same volume cannot race on its shared .ecx/.ecj/.vif sidecar files.
* fix(ec): key EC balance shards by (collection, volume id)
A numeric volume id can be reused across collections, and EC identity is
(collection, vid) (see store_ec_attach_reservation.go). The ecbalancer keyed
Node.shards by vid alone, so volumes sharing an id across collections merged into
one entry — letting dedup delete a "duplicate" that is actually a different
collection's shard, and letting moves act across collections. Key shards by
(collection, vid) throughout so each volume stays distinct.
* fix(ec): credit freed capacity from dedup before later balance phases
Dedup deletions are simulated only by applyMovesToTopology, which cleared shard
bits but did not return the freed disk/node/rack slots. Later phases reject
destinations with no free slots, so a slot opened by dedup could not be reused in
the same Plan/ec.balance run. applyMovesToTopology now credits the freed
disk/node/rack capacity for dedup moves (non-dedup moves still rely on the inline
accounting their phase already did).
* test(ec): add multi-disk EC balance integration test
Cover issue 9593 end-to-end at the unit level the old tests missed: build the
master's actual multi-disk wire format (same-type disks collapsed into one
DiskInfo, real DiskId only in per-shard records), run it through a real
ActiveTopology and the Detection entry point, then replay the planned moves with
the volume server's true semantics (node-wide VolumeEcShardsDelete) and assert no
EC shard is ever lost. Covers a balanced spread, a one-node-concentrated volume,
and a multi-rack spread, and asserts moves are safe (no same-node cross-disk),
correctly attributed to the source disk, and redistribute concentrated volumes
across both other racks and multiple destination disks.
* fix(ec): aggregate per-disk EC shards when verifying multi-disk volumes
collectEcNodeShardsInfo overwrote its per-server entry for each EcShardInfo of a
volume. A multi-disk node reports one EcShardInfo per physical disk holding shards
of the volume, so only the last disk's shards survived — the node looked like it
was missing shards it actually had. This made ec.encode's pre-delete verification
(and ec.decode) under-count volumes whose shards are spread across disks on one
server, falsely aborting the encode on multi-disk clusters. Union the per-disk
shard sets per server instead.
Also make verifyEcShardsBeforeDelete poll briefly: shard relocations reach the
master via volume-server heartbeats, so a freshly distributed shard set may not be
fully visible the instant the balance returns. Retry before concluding the set is
incomplete; genuine loss still fails after the retries are exhausted.
* test(ec): end-to-end multi-disk EC balance shard-loss regression
Start a real cluster of multi-disk volume servers (3 servers x 4 disks),
EC-encode a volume, run ec.balance, and assert hard invariants the prior
integration tests only logged: after encode all 14 shards exist, ec.balance loses
no shard, shards span more than one disk per node, and cluster.status counts
physical disks (not one per node). This reproduces issue 9593 end to end and would
have caught the multi-disk shard-aggregation bug fixed alongside it.
* fix(ec): bring EC balance worker/plugin path to parity with shell
- Per-volume serialization and phase order: key the plugin proposal dedupe by
(collection, volume) instead of (volume, shard, source), so the scheduler runs
only one of a volume's moves at a time (within a run and against in-flight jobs).
Concurrent same-volume moves raced on the volume's .ecx/.ecj/.vif sidecars; and
because the planner emits a volume's moves in phase order, they now execute in
order across detection cycles, matching the shell.
- disk_type "hdd": normalize via ToDiskType (hdd -> "" HardDriveType) while keeping
a "filter requested" flag, so disk_type=hdd matches the empty-keyed HDD disks
instead of nothing; apply the canonical type to planner options and move params.
- Replica placement: expose shard_replica_placement in the admin config form and
read it into the worker config, mirroring ec.balance -shardReplicaPlacement.
* test(ec): rename worker in-process test (not a real integration test)
The worker-package multi-disk tests build a fake master topology and simulate
move execution; they are not real-cluster integration tests. Rename
integration_test.go -> multidisk_detection_test.go and drop the Integration
prefix so 'integration' refers only to the real-cluster E2Es in test/erasure_coding.
* ci(ec): remove redundant ec-integration workflow
ec-integration.yml duplicated EC Integration Tests under the same workflow name
but ran only 'go test ec_integration_test.go' (one file), so it never ran new
test files (e.g. multidisk_shardloss_test.go) and was a strict, path-filtered
subset of ec-integration-tests.yml, which already runs 'go test -v' over the whole
test/erasure_coding package on every push/PR.
* fix(ec): worker falls back to master default replication for EC balance
For strict parity with the shell, the EC balance worker now uses the master's
configured default replication as the replica-placement fallback when no explicit
shard_replica_placement is set, instead of always defaulting to even spread.
The maintenance scanner reads it via GetMasterConfiguration each cycle and passes
it through ClusterInfo.DefaultReplicaPlacement; detection resolves the constraint
(explicit config wins, else master default, else none) in resolveReplicaPlacement.
A zero-replication default (the common 000 case) still means even spread, so the
common configuration is unchanged.
* fix(ec): plugin path populates master default replication too
The plugin worker built ClusterInfo with only ActiveTopology, so the master
default replication fallback added for the maintenance path never reached
plugin-driven EC balance detection — empty shard_replica_placement still meant
even spread there. Fetch the master default via GetMasterConfiguration (new
pluginworker.FetchDefaultReplicaPlacement) and set ClusterInfo.DefaultReplicaPlacement
so both detection paths resolve replica placement identically to the shell.
* docs(ec): empty shard replica placement uses master default, not even spread
The EC balance config text (admin plugin form, legacy form help text, and
the struct/proto field comments) still said an empty shard_replica_placement
spreads evenly. The runtime resolves empty to the master default replication
(resolveReplicaPlacement), matching shell ec.balance, with even spread only
when that default is empty or zero. Update the text to match and regenerate
worker_pb for the proto comment change.

fix(ec): pack EC shards onto fewer disks instead of refusing the task (#9588)
The planner refused to create an EC task unless it found totalShards distinct (server, disk_id) targets, so a cluster with fewer disks than shards (e.g. 8 single-disk servers for a 10+4 scheme) could never encode. A disk safely holds several distinct shards of one volume: each is its own .ecNN file and ReceiveFile keys by that extension. Drop the strict check and let createECTargets round-robin shards across the available disks, matching ec.encode's "4,4,3,3" fallback. The minTotalDisks floor (ceil(total/parity)) already keeps any disk under parityShards shards, so the volume still survives losing any one disk. Reserve capacity for the actual per-disk shard count rather than assuming one shard each, so packing doesn't over-commit disk slots. |

fix(iceberg): dial filer gRPC address verbatim in plugin worker (#9527)
* fix(iceberg): dial filer gRPC address verbatim in plugin worker dialFiler was running its address argument through pb.ServerAddress.ToGrpcAddress, whose single-port fallback adds +10000 to any host:port — so when the admin forwards ClusterContext.FilerGrpcAddresses (already host:grpcPort) to the worker, the iceberg handler turns the real gRPC port (e.g. 18888) into a non-existent 28888 and dispatched jobs fail with connection refused. Drop the conversion; the address is already dialable. Tests that produced fake filer addresses in dual-port form now return host:grpcPort to match the new contract. * test(ec): use renamed detection_interval_minutes field The admin_runtime.detection_interval_seconds field was renamed to detection_interval_minutes back in May. This integration test was not updated, so the unknown JSON field was silently ignored and the scheduler fell back to the default detection interval (17 min for erasure_coding), which exceeds the test's 5-minute wait and times out. Switch to detection_interval_minutes: 1 — local run completes in ~120s. |

fix(ec): blanket-clean every destination over the full shard range (#9512)
* fix(ec): blanket-clean every destination over the full shard range The previous cleanup pass walked t.sources only, with the shard ids the topology had reported at detection time. In the wild, a destination can end up with EC shards mounted that the topology snapshot didn't list — shards on a sibling disk that hadn't heartbeated, or shards left over from a concurrent attempt's mount step. FindEcVolume still returns true, so the next ReceiveFile trips the mounted-volume guard. Cleanup now unions t.sources (with ShardIds) and t.targets and issues unmount + delete over [0..totalShards-1] on each. Both RPCs are idempotent on missing shards, so the wider sweep is free. Two new tests cover the gap: shards mounted beyond what t.sources lists, and a target-only destination with no source row. * log(ec): include disk_id in EC unmount/delete/refusal log lines The current logs identify the volume and shard but leave disk_id off, which makes the cross-server cleanup story hard to follow when multiple disks of one server hold pieces of the same volume: UnmountEcShards 4121.1 -> add disk_id ec volume video-recordings_4121 shard delete [1 5] -> add per-loc disk_id volume server X:Y deletes ec shards from 4121 [...] -> add disk_id ReceiveFile: ec volume 4121 is mounted; refusing... -> add disk_ids ReceiveFile's refusal now names the disk_ids actually holding the mount so operators can see whether the next cleanup pass needs to target a sibling disk. Added Store.FindEcVolumeDiskIds / Store::find_ec_volume_disk_ids as the supporting primitive. Mirrored in seaweed-volume/src/ (unmount log in Store::unmount_ec_shard, heartbeat delete log in diff_ec_shard_delta_messages, refusal in the ReceiveFile handler). * test(ec): stub VolumeEcShardsUnmount/Delete on the fake volume server The plugin-worker EC tests boot a fake volume server that embeds UnimplementedVolumeServerServer. After the worker started calling VolumeEcShardsUnmount + VolumeEcShardsDelete pre-distribute, the default Unimplemented response surfaced as fourteen "method not implemented" errors and TestErasureCodingExecutionEncodesShards failed. Both RPCs are no-ops here — nothing on the fake server has mounted state or persisted shard files to remove. |

fix(ec): clear cross-server stale EC shards before re-distribute (#9478) (#9499)
* fix(ec): clear cross-server stale EC shards before re-distribute (#9478) A previous failed encode leaves partial .ec?? shards mounted on destination volume servers that are not the .dat owner. PR #9480 only prunes when the .dat sits on a sibling disk of the SAME store, so the cross-server case stays stuck: every retry trips volume_grpc_copy.go:570's "ec volume %d is mounted; refusing overwrite" guard and the scheduler loops. Detection already lists existing EC shards as CleanupECShards sources; plumb the shard ids through (ActiveTopology.GetECShardLocations, TaskSourceSpec, TaskSource.shard_ids) and have the EC worker call VolumeEcShardsUnmount + VolumeEcShardsDelete on each destination after the local shard set is generated and before distributeEcShards. Skip EC-shard sources in getReplicas so the post-encode VolumeDelete step does not target destination-only nodes. Integration test mounts a partial shard subset, asserts the mounted-volume refusal, runs cleanupStaleEcShards, and asserts the next ReceiveFile lands. * chore(ec): tighten code comments in stale-shard cleanup Drop issue-number refs from code comments and shorten the docstrings on cleanupStaleEcShards / unmountAndDeleteEcShards / getReplicas plus the new test file. Behavior unchanged. * fix(ec): skip empty-ShardIds locations; dedupe getReplicas by node GetECShardLocations dropped entries where ecShardMatchesCollection saw a phantom info record with EcIndexBits=0 — without ShardIds, getReplicas misread the resulting source as a regular replica and would have called VolumeDelete on a destination-only node. getReplicas now dedupes by Node since VolumeDelete is server-wide; per-disk source rows on the same server collapse to one call. * refactor(ec): use MaxShardCount and ShardBits in collectShardIdsForDisk Drop the literal 32 bit-iteration bound for erasure_coding.MaxShardCount and treat the EcIndexBits union as a ShardBits so Count() drives the slice preallocation. Keeps the helper aligned with the rest of the EC code and survives any future expansion of the shard-count ceiling. |

fix(ec): verify full shard set before deleting source volume (#9490) (#9493)
* fix(ec): verify full shard set before deleting source volume (#9490) Before this change, both the worker EC task and the shell ec.encode command would delete the source .dat as soon as MountEcShards returned — even if distribute/mount failed partway, leaving fewer than 14 shards in the cluster. The deletion was logged at V(2), so by the time someone noticed missing data the only trace was a 0-byte .dat synthesized by disk_location at next restart. - Worker path adds Step 6: poll VolumeEcShardsInfo on every destination, union the bitmaps, and refuse to call deleteOriginalVolume unless all TotalShardsCount distinct shard ids are observed. A failed gate leaves the source readonly so the next detection scan can retry. - Shell ec.encode adds the same gate after EcBalance, walking the master topology with collectEcNodeShardsInfo. - VolumeDelete RPC success and .dat/.idx unlinks now log at V(0) so any source destruction is traceable in default-verbosity production logs. The EC-balance-vs-in-flight-encode race is intentionally left for a follow-up; balance should refuse to move shards for a volume whose encode job is not in Completed state. * fix(ec): trim doc comments on the new shard-verification path Drop WHAT-describing godoc on freshly added helpers; keep only the WHY notes (query-error policy in VerifyShardsAcrossServers, the #9490 reference at the call sites). * fix(ec): drop issue-number anchors from new comments Issue references age poorly — the why behind each comment already stands on its own. * fix(ec): parametrize RequireFullShardSet on totalShards Take totalShards as an argument instead of reading the package-level TotalShardsCount constant. The OSS callers continue to pass 14, but the helper is now usable with any DataShards+ParityShards ratio. * test(plugin_workers): make fake volume server respond to VolumeEcShardsInfo The new pre-delete verification gate calls VolumeEcShardsInfo on every destination after mount, and the fake server's UnimplementedVolumeServer returns Unimplemented — the verifier read that as zero shards on every node and aborted source deletion. Build the response from recorded mount requests so the integration test exercises the gate end-to-end. * fix(rust/volume): log .dat/.idx unlink with size in remove_volume_files Mirror the Go-side change in weed/storage/volume_write.go: stat each file before removing and emit an info-level log for .dat/.idx so a destructive call is always traceable. The OSS Rust crate previously unlinked them silently. * fix(ec/decode): verify regenerated .dat before deleting EC shards After mountDecodedVolume succeeds, the previous code immediately unmounts and deletes every EC shard. A silent failure in generate or mount could leave the cluster with neither shards nor a valid normal volume. Probe ReadVolumeFileStatus on the target and refuse to proceed if dat or idx is 0 bytes. Also make the fake volume server's VolumeEcShardsInfo reflect whichever shard files exist on disk (seeded for tests as well as mounted via RPC), so the new gate can be exercised end-to-end. * fix(ec): address PR review nits in verification + fake server - Drop unused ServerShardInventory.Sizes field. - Skip shard ids >= MaxShardCount before bitmap Set so the ShardBits bound is explicit (Set already no-ops on overflow, this is for clarity). - Nil-guard the fake server's VolumeEcShardsInfo so a malformed call doesn't panic the test process. |

refactor(s3/lifecycle): drop Per-Run Time Limit knob; use scheduler's Execution Timeout (#9494)
* refactor(s3/lifecycle): drop Per-Run Time Limit knob; use scheduler's Execution Timeout "Per-Run Time Limit (minutes)" duplicated the admin scheduler's "Execution Timeout (s)" — both are wall-clock caps on the same Execute call, stacked via context.WithTimeout. Whichever was shorter won. Under defaults the scheduler's 90s timeout always clobbered the worker's 60-min cap, so the "Per-Run Time Limit" knob was effectively dead unless an operator also raised Execution Timeout, and operators had to keep two values in agreement. Remove the worker-side knob and declare a sane scheduler default on the handler descriptor: - WorkerConfigForm: nil (was: one section with one field) - Config.MaxRuntime removed; ParseConfig drops max_runtime_minutes - Handler no longer wraps ctx in context.WithTimeout(MaxRuntime); runCtx is just the ctx the scheduler passes - AdminRuntimeDefaults.ExecutionTimeoutSeconds = 3600 (1h) and JobTypeMaxRuntimeSeconds = 3600 — the scheduler's global 90s default would otherwise kill every real run Tests: - TestParseConfigDefaults loses the MaxRuntime check; new TestParseConfigIgnoresWorkerValues documents the contract - TestDescriptor_WorkerConfigFormIsAbsent pins that the form is gone so a future re-add forces a conscious revisit - TestDescriptor_AdminRuntimeDefaultsBoundExecutionTimeout pins the 1h default with a comment about the 90s scheduler floor * fix(s3/lifecycle): no per-pass timeout by default Lifecycle is a scheduled batch — its natural duration is "as long as today's events take." The 1h default ExecutionTimeoutSeconds from the previous commit was still a footgun: too low truncates legitimate large-bucket passes; too high makes the value meaningless. Set both ExecutionTimeoutSeconds and JobTypeMaxRuntimeSeconds to math.MaxInt32 (~68 years) to say "no timeout in practice" in a code-review-readable way. Operators who genuinely want a wall-clock cap can set one in the admin UI; the scheduler's context.WithTimeout machinery is unchanged (we just hand it an effectively-infinite duration). Note: the scheduler floors ExecutionTimeout at 90s (defaultScheduledExecutionTimeout in weed/admin/plugin/plugin_scheduler.go), so 0 doesn't mean "unlimited" — it clamps back to 90s. A literal math.MaxInt32 is the way to express the intent without touching the shared scheduler code. Test updated to pin math.MaxInt32 and document the rationale so a future tighter cap fails the test and forces conscious revisit. |

feat(s3/lifecycle): enable scheduler by default (#9492)
S3 lifecycle is a standard bucket feature — operators set PutBucketLifecycleConfiguration through the S3 API expecting the configured expirations to actually fire. With the prior default (scheduler enabled=false), buckets with lifecycle XML silently retained data past their declared expiration until an operator noticed and turned the scheduler on. The failure mode of enabled-by-default is "worker runs every day and fast-exits on buckets with no lifecycle rules" — cheap. The failure mode of disabled-by-default is "data lingers, looks like it expired, doesn't" — bad. Enabled-by-default matches both the AWS S3 default behavior and the operator's natural mental model. Operators who want the worker off can still disable it via the admin UI; once a persisted config exists, this descriptor default no longer applies (the persisted Enabled state wins). Test pins the choice so a future flip to false fails loud. |

feat(s3/lifecycle): plumb WalkerInterval through worker admin config (#9485)
* feat(s3/lifecycle): throttle steady-state walker by cfg.WalkerInterval The steady-state and empty-replay walker fired on every dailyrun.Run invocation, which is fine when Run is called at the bucket-walk cadence the operator intends (e.g., once per hour or once per day), but catastrophic when a fast driver like the s3tests CI workflow or the admin worker scheduler invokes Run at multi-second cadence — each tick ran a full subtree scan per shard, crushing the filer. Decouple walker cadence from Run() invocation cadence: persist LastWalkedNs in the per-shard cursor and fire the steady-state / empty-replay walker only when (runNow - LastWalkedNs) >= cfg.WalkerInterval. Cold-start and recovery walker fires (RecoveryView) stay unconditional since those are bounded events that must run when their trigger condition (no cursor, hash mismatch) is met. Recovery walker fires also update LastWalkedNs so the subsequent steady-state pass doesn't double-walk. cfg.WalkerInterval=0 keeps the prior "fire every pass" behavior — the in-repo integration tests and s3tests fast driver continue to work unchanged. Production deployments should set this to the walk cost budget (typically 1h-24h depending on cluster size). Cursor file is back-compat: last_walked_ns is omitempty, so cursor files written before this change decode as LastWalkedNs=0, which walkerDue treats as "never walked steady-state" → walker fires next pass to establish the anchor (same path a cold-start cursor takes). No version bump. Operator surface for WalkerInterval is the dailyrun.Config struct; plumbing through worker.tasks.s3_lifecycle.Config and the admin schema is a follow-up. * fix(s3/lifecycle): suppress walker double-fire within a single pass Two gemini-code-assist findings: 1. walkerDue with interval=0 returned true even when lastWalkedNs == runNow.UnixNano() — the cold-start / recovery branch already fired the walker this pass, and the steady-state fall-through fired it again. RecoveryView is a superset of every per-shard partition, so the second walk added zero coverage and burned a full subtree scan. Add a within-pass guard at the front of walkerDue: if the cursor's LastWalkedNs equals runNow's UnixNano, the walker already ran this pass — skip. 2. The empty-replay branch passed persisted.LastWalkedNs to walkerDue instead of the local lastWalkedNs variable the rest of runShard threads through. Trivially equal at this point in the function, but the inconsistency would mask a future bug if any code above the branch ever sets lastWalkedNs. Test updates: TestWalkerDue gains the within-pass guard case plus a companion "earlier same pass still fires" sanity check. TestRunShard_ColdStartDoesNotDoubleWalk is new and pins the integration: cold-start runShard with WalkerInterval=0 must call cfg.Walker exactly once, not twice. * fix(s3/lifecycle): reject negative WalkerInterval + lift within-pass guard Two coderabbit findings: 1. validate() now rejects negative cfg.WalkerInterval. A typo like -1h previously fell through walkerDue's `interval <= 0` branch and silently re-enabled "walk every pass" — the exact behavior the throttle was added to prevent. The admin-config parser already clamps negative input to zero, but callers using dailyrun.Config directly (tests, embedders) now get a loud error instead. 2. Within-pass double-fire suppression moves out of walkerDue and into runShard's walkedThisPass local flag. walkerDue's equality check (lastWalkedNs == runNow.UnixNano) was correct in production (each pass freezes runNow at time.Now().UTC, no collisions) but fragile in tests that inject the same runNow across distinct passes — the test would see false suppression. Separating the concerns also makes walkerDue answer one question (persisted-state throttle) and runShard another (within-pass call-site dedup). walker_interval_test.go: TestValidate_RejectsNegativeWalkerInterval pins the new validation. TestWalkerDue's within-pass cases move out (the function is pure throttle now); TestRunShard_ColdStartDoesNot DoubleWalk still pins the integration behavior end-to-end. * feat(s3/lifecycle): plumb WalkerInterval through worker admin config #9484 added cfg.WalkerInterval to dailyrun.Config but left the worker side wired to zero — operators couldn't actually use the throttle without recompiling. Add the admin-schema knob: - New constant WalkerIntervalMinutesAdminKey = "walker_interval_minutes" follows the MetaLogRetentionDaysAdminKey pattern (Int64, minutes unit, 0 = unbounded / fire every pass). - New Config.WalkerInterval populated in ParseConfig from adminValues; negative / zero stay at zero so the prior "fire every pass" semantics keep the in-repo integration tests and the s3tests sub-minute driver working unchanged. - handler.go: admin form field with operator-facing label and description, default in DefaultValues, value forwarded to dailyrun.Run via cfg.WalkerInterval. Tests cover the default-zero, positive, and negative cases — same shape as the MetaLogRetention tests so the parsing contract stays consistent. Stacked on #9484; rebase after that lands. |

feat(s3/lifecycle): apply cluster rate limit to walker dispatch (#9471)
Phase 4b shipped the walker without plugging it into the cluster rate.Limiter that processMatches honors. A walker hitting a large bucket on the recovery branch could burst LifecycleDelete RPCs past the cluster_deletes_per_second cap that streaming-replay respects. WalkerDispatcher now takes a *rate.Limiter and waits on it before each RPC, observing the wait time on S3LifecycleDispatchLimiterWaitSeconds just like processMatches does. The handler passes the same limiter to both paths so replay + walk share one budget; nil disables throttling (unchanged default). Tests pin: the limiter actually delays a dispatch when the burst token is drained, and a ctx cancellation in Limiter.Wait surfaces as an error without sending the RPC. |

feat(s3/lifecycle): operator-declared meta-log retention activates PromotedHash (#9473)
* feat(s3/lifecycle): operator-declared meta-log retention activates PromotedHash dailyrun.Config.RetentionWindow has been wired since Phase 4b but the handler never supplied a value, so runShard always fell back to maxTTL and engine.PromotedHash hashed nothing. The partition-flip recovery trigger was dormant by design "until the handler plumbs the real meta-log retention here." This PR plumbs it via a new admin form field: Meta-Log Retention (days) — 0 = unbounded (current behavior). When set, ParseConfig converts days to a time.Duration on cfg.MetaLogRetention. The handler passes it as dailyrun.Config.RetentionWindow, which runShard then feeds to engine.PromotedHash. Rules whose TTL exceeds the declared window land in the walk partition; the next time an operator shrinks retention so a previously replay-eligible rule slips past it, PromotedHash mismatches → recovery branch fires → walker re-evaluates the rule across the whole filer tree. 0 stays the default, so existing deployments see no behavior change. * chore(s3/lifecycle): rephrase days->duration conversion gemini-code-assist flagged the original form as a compile error, which it wasn't (time.Duration is a named int64 and supports * with other time.Durations — the test suite verified the value was correct). The suggested form is more idiomatic regardless: days*24 happens in int64 space before the lift to time.Duration, so the unit is unambiguous. |

feat(s3/lifecycle): delete streaming algorithm path (Phase 5b) (#9466)
* feat(s3/lifecycle): delete streaming algorithm path (Phase 5b) Phase 5a (PR #9465) retired the algorithm flag and made daily_replay the only execution path. The streaming-side code (scheduler.Scheduler, scheduler.BucketBootstrapper, dispatcher.Pipeline, dispatcher.Dispatcher, dispatcher.FilerPersister, and their tests) has had no in-tree caller since then. This PR deletes it. Net change: ~4800 lines removed, ~130 added (the scheduler/configload tests' helper file the deleted bootstrap_test.go used to host). Removed: - weed/s3api/s3lifecycle/scheduler/{bootstrap,bootstrap_test, scheduler,scheduler_test,pipeline_fanout_test, refresh_default,refresh_s3tests}.go - weed/s3api/s3lifecycle/dispatcher/{dispatcher,dispatcher_test, dispatcher_helpers_test,edge_cases_test,multi_shard_test, pipeline,pipeline_test,pipeline_helpers_test,toproto_test, dispatch_ticks_default,dispatch_ticks_s3tests}.go - weed/s3api/s3lifecycle/dispatcher/filer_persister_test.go (FilerPersister deleted; FilerStore tests don't need their own file) - weed/shell/command_s3_lifecycle_run_shard{,_test}.go (debug-only shell command that only ever wrapped the streaming pipeline; the production worker now exercises the same path every daily run) Trimmed: - dispatcher/filer_persister.go down to FilerStore + NewFilerStoreClient — the small interface daily_replay's cursor persister (dailyrun.FilerCursorPersister) plugs into. Kept (still consumed by daily_replay): - scheduler/configload.{go,_test.go} (LoadCompileInputs, AllActivePriorStates) - dispatcher/sibling_lister.{go,_test.go} (NewFilerSiblingLister, FilerSiblingLister) - dispatcher/filer_persister.go (FilerStore, NewFilerStoreClient) scheduler/testhelpers_test.go restores fakeFilerClient, fakeListStream, dirEntry, fileEntry — helpers the configload tests used to share with the deleted bootstrap_test.go. Updates the handler-package doc strings and one reader-package comment that still named the streaming pipeline. * fix(s3/lifecycle): hold lock through tree read in test filer client gemini caught an inconsistency in scheduler/testhelpers_test.go: LookupDirectoryEntry reads c.tree under c.mu, but ListEntries was releasing the lock before reading c.tree.

feat(s3/lifecycle): retire algorithm flag, daily_replay is the only path (Phase 5a) (#9465)
feat(s3/lifecycle): remove algorithm flag, daily_replay is the only path (Phase 5a)
With Phase 4b on master the daily_replay path covers every rule kind
and the streaming algorithm has no remaining responsibilities. This
PR retires the algorithm flag from the worker:
- Drop the "Algorithm" enum field from AdminConfigForm and its
DefaultValues entry.
- Drop the if/else routing in Execute — every Execute call now
routes straight into executeDailyReplay.
- Drop the streaming-only worker fields (DispatchTick,
CheckpointTick, RefreshInterval, BootstrapInterval) and their
matching form fields. None of them are read by the daily_replay
path; keeping them in the form would suggest tuning knobs that
don't do anything.
- Drop AlgorithmStreaming / AlgorithmDailyReplay constants and the
Config.Algorithm field.
The streaming-path packages (s3lifecycle/scheduler, s3lifecycle/dispatcher)
remain on the tree; they're now reachable only by the
weed shell s3.lifecycle.run-shard debug command and the few helpers
(LoadCompileInputs, FilerStore, FilerSiblingLister) the daily_replay
worker still uses. Phase 5b deletes the dead code.
Tests prune the cadence-default assertions to the single remaining
field (max_runtime_minutes).

feat(s3/lifecycle): Phase 4b — daily walker for recovery and steady state (#9459)
* feat(s3/lifecycle): plumb RetentionWindow into dailyrun.Config
Adds a Config.RetentionWindow field that runShard threads into
engine.PromotedHash. Zero (the default) falls back to maxTTL, which
matches Phase 4a behavior — PromotedHash stays empty and the
partition-flip recovery trigger stays dormant.
Pure plumbing. The handler still passes zero so nothing changes at
runtime. The walker work (Phase 4b proper) sets a real retention from
the meta-log boundary and the partition-flip trigger starts firing.
* feat(s3/lifecycle): WalkerDispatcher adapter for the daily-run walker
Phase 4b prep. Implements bootstrap.Dispatcher on top of LifecycleClient
so the same LifecycleDelete RPC drives both the meta-log replay path
and the walker. No CAS witness — the server's identityMatches treats
nil ExpectedIdentity as a bootstrap call and rebuilds the witness from
the live entry, which is the right contract for a full-tree walk.
Adds VersionID to bootstrap.Entry so versioned-bucket walks address
the right version. MPU init uses DestKey for ObjectPath (matching the
prefix-match contract); rejecting empty DestKey keeps malformed init
records out of the dispatch path.
Not wired yet — runShard still doesn't invoke the walker. Follow-up
commits add the ListFunc adapter and the recovery-branch wiring.
* feat(s3/lifecycle): wire Walker hook into runShard's recovery branch
Adds a Config.Walker callback that fires on rule-content edit /
partition flip BEFORE the cursor rewinds, so already-due objects across
the rewritten rule set get caught instead of waiting on meta-log
replay alone. The callback receives engine.RecoveryView(snap) and the
per-shard ID; nil disables it (Phase 4a behavior preserved).
Decoupling the wiring from the implementation: the handler-side
WalkerFunc that drives bootstrap.Walk via the filer is the follow-up
commit, and tests can stub the callback without standing up the full
filer/client/lister harness.
Tests pin: walker fires exactly once on hash mismatch, walker error
propagates and leaves the cursor unchanged, nil Walker is a no-op.
* feat(s3/lifecycle): WalkBuckets composes ListFunc + Dispatcher per shard
Adds dailyrun.WalkBuckets — the composable driver the handler-side
WalkerFunc will call. Iterates a bucket list, wraps the supplied
bootstrap.ListFunc with a per-shard filter (Path for non-MPU, DestKey
for MPU init), and runs bootstrap.Walk per bucket using the supplied
Dispatcher. First bucket error wins; remaining buckets log and run to
completion so one filer flake doesn't kill the shard.
Composable rather than monolithic so callers and tests can swap parts:
production uses a filer-backed ListFunc + WalkerDispatcher; tests use
bootstrap.EntryCallback + a stub. The filer-backed ListFunc is the
next commit.
Tests pin: shard filter routes only matching entries, MPU shard uses
DestKey not the .uploads/<id> path, single-bucket error propagates
while other buckets still run, ctx cancellation short-circuits between
buckets, nil guards on view/list/dispatch.
* feat(s3/lifecycle): filer-backed ListFunc for the daily-run walker
Phase 4b: dailyrun.FilerListFunc returns a bootstrap.ListFunc that
streams entries under <bucketsPath>/<bucket> by paginated SeaweedList.
Recurses into regular directories; .versions/ and .uploads/ are
skipped at this stage so they don't surface as raw children — the
sibling expansion (versioned NoncurrentDays state, MPU init dispatch)
lands in the next commit.
listAll and isVersionsDir are ported from scheduler/bootstrap.go's
same-named helpers. Phase 5 deletes the scheduler copies along with
the streaming path.
Tests pin: flat listing, recursion through nested directories,
.versions/ and .uploads/ skipped, kill-resume via the start path
contract, nil-client error, attribute propagation (mtime / size /
IsLatest default).
* feat(s3/lifecycle): versioned-sibling expansion in FilerListFunc
Adds the .versions/<key>/ expansion to the daily-run's filer-backed
ListFunc. Each call emits one bootstrap.Entry per sibling (real
version files + the bare null version, when found) with the same
sibling state the streaming bootstrap injects via reader.Event:
- Path = logical key (not the .versions/<file> physical path), so
bootstrap.Walk's MatchPath uses the user's intended path.
- VersionID per sibling (version_id or "null").
- IsLatest resolved via parent's ExtLatestVersionIdKey, falling back
to explicit-null-bare, falling back to newest-by-mtime.
- NoncurrentIndex rank computed against the latest's position.
- SuccessorModTime: SuccessorFromEntryStamp if stamped, else the
previous-newer sibling's mtime (legacy derivation).
- IsDeleteMarker from ExtDeleteMarkerKey.
- NumVersions = len(siblings).
Two-pass walk so .versions/ dirs run before regular files; the bare
null-version path is recorded in skipBare so pass 2 doesn't emit it
twice.
expandVersionsDir and lookupNullVersion are ported from
scheduler/bootstrap.go. Sort order, latest resolution, and successor
derivation must agree with that path verbatim so streaming and walker
reach the same verdict on the same objects. Phase 5 deletes the
scheduler copy.
MPU init (.uploads/<id>) remains skipped — the dedicated commit emits
it with IsMPUInit and DestKey.
Tests pin: pointer-wins latest resolution, no-pointer newest-sibling
fallback, explicit-null-is-latest with skipBare suppression of the
bare emission, coincidentally-named .versions folder recursing as a
regular subdir, delete-marker propagation.
* feat(s3/lifecycle): emit MPU init records from FilerListFunc
Last gap in the filer-backed ListFunc. A directory at .uploads/<id>
carrying ExtMultipartObjectKey is the MPU init record; emit one
bootstrap.Entry with IsMPUInit=true and DestKey set to the user's
intended path. The walker's MatchPath uses DestKey for prefix
matching; the WalkerDispatcher uses it for the LifecycleDelete RPC's
ObjectPath. .uploads/<id> directories without the extended key are
mid-write before metadata landed and stay skipped.
isMPUInitDir is upgraded from the path-shape-only stub to the full
shape + extended-attr check that mirrors router.mpuInitInfo and
scheduler/bootstrap.go's same-named helper.
Tests pin: valid init record emits with the right DestKey, missing
ExtMultipartObjectKey skips the directory.
* feat(s3/lifecycle): wire walker into executeDailyReplay
Activates the recovery-branch walker. The handler composes the three
Phase 4b building blocks — FilerListFunc + WalkerDispatcher + WalkBuckets
— into a dailyrun.WalkerFunc and passes it via Config.Walker. The
bucket list is derived from the compiled inputs so it matches the
engine snapshot exactly.
Effect on master behavior: when a worker observes a RuleSetHash or
PromotedHash mismatch on its persisted cursor (rule content edited /
partition flip), runShard now walks the live filer tree under the
RecoveryView before rewinding the cursor. Already-due objects across
the rewritten rule set fire immediately instead of waiting on the
sliding meta-log replay.
Still scoped to replay-eligible action kinds because
checkSnapshotForUnsupported continues to reject walker-bound rules
(ExpirationDate / ExpiredDeleteMarker / NewerNoncurrent) and
scan_only-promoted rules at the top of Run. The follow-up commit
relaxes the gate once the steady-state walker over RulesForShard's
walk view is wired so those rules fire every day, not just on rule
edits.
* feat(s3/lifecycle): steady-state walker + drop unsupported-rule gate
Adds the second walker invocation in runShard. After the recovery
check passes, runShard derives the walk view via snap.RulesForShard
(using the same retentionWindow PromotedHash used, so the partition
is consistent) and runs the walker over it. The view holds
walker-bound action kinds (ExpirationDate / ExpiredDeleteMarker /
NewerNoncurrent) plus any replay-eligible rules promoted to walk by
retention shortage; an empty view skips the call so non-versioned,
replay-only deployments don't pay an O(N) bucket walk per run.
With the walker now servicing every rule kind, checkSnapshotForUnsupported
and its UnsupportedRuleError type are obsolete. router.Route gates
replay on Mode == ModeEventDriven, so walker-bound and scan_only
rules are silently dropped by replay and picked up by the walker
instead — no double-dispatch. Drop the gate, delete replayability.go
+ replayability_test.go, and remove the handler's redundant
IsUnsupportedRule branch.
* fix(s3/lifecycle): walker dispatcher nil-response guard + retention-comment
Two PR-review fixes on 9459:
1. WalkerDispatcher.Delete used to panic on a (nil, nil) RPC return —
add a defensive nil-response check so the walk halts cleanly
instead. Spotted by coderabbit.
2. The retentionWindow=maxTTL comment in runShard claimed PromotedHash
"stays empty" in fallback mode, which gemini correctly pointed out
is only true once rules are active. During bootstrap (rules
compiled but IsActive=false) MaxEffectiveTTL is 0 while
PromotedHash counts every non-disabled rule, so promoted becomes
non-empty and the next post-activation run hits the recovery
branch. That's the intended bootstrap walk — rewrite the comment
to explain it rather than misstate the invariant.
Test: pins nil-response → error path on WalkerDispatcher.
* fix(s3/lifecycle): explicit stale-pointer fallback in versioned expansion
Reviewer caught a structural bug in expandVersionsDir's latest
resolution: when ExtLatestVersionIdKey was set but no scanned sibling
carried that id (stale pointer), the code left latestPos at the
default 0 without ever entering the no-pointer fallback. Today the
two paths yield the same value (newest sibling wins), but the
implicit fall-through makes the intent unclear and would break
silently if the no-pointer branch ever did anything more than
latestPos=0.
Track a pointerResolved flag explicitly so the no-pointer branch
(including the explicit-null-bare check) re-runs on a stale pointer.
Behavior unchanged today.
Test pins: stale pointer + two real versions falls back to
newest-sibling (vnew, not vold).
* feat(s3/lifecycle): walker-side dispatch metrics in WalkerDispatcher
Mirrors the Phase 6 instrumentation already on the replay side
(processMatches) onto the walker's Delete dispatch. Every walker
dispatch now bumps S3LifecycleDispatchCounter with the resolved
outcome (or TRANSPORT_ERROR / NIL_RESPONSE for the failure paths) so
streaming, daily_replay's replay drain, and daily_replay's walker
share a single per-(bucket, kind, outcome) counter view.
Lands together with the rest of Phase 4b — no new metric, just an
extra observation site for the existing one.
