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> |

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 |

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. |

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. |

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. |

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> |

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(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(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. |

fix(ec): skip re-encode when EC shards already exist for the volume (#9448) (#9458)
* fix(ec): skip re-encode when EC shards already exist for the volume (#9448) When an earlier EC encoding succeeded but the post-encode source-delete left a regular replica behind on one of the servers, the next detection cycle proposes the same volume again. The new encode tries to redistribute shards to targets that already have them mounted, the volume server returns `ec volume %d is mounted; refusing overwrite`, the task fails, and detection re-queues the volume. The cycle repeats forever — issue #9448. The existing `metric.IsECVolume` skip catches the case where the canonical metric is reported on the EC-shard side of the heartbeat, but when the master sees BOTH a regular replica AND its EC shards in the same volume list, the canonical metric we pick is the regular replica and IsECVolume is false. Add a second guard that checks the topology directly via `findExistingECShards` (already present and indexed) and skip the volume when any shards exist, logging a warning that points the admin at the stuck source. This breaks the loop. Auto-cleanup of the orphaned replica is left as follow-up work — deleting a source replica from inside the detector is only safe with a re-verification step right before the delete, plus a config opt-in, and is best done in its own change. * fix(ec): #9448 guard only fires when EC shard set is complete The first version of the #9448 guard tripped on `len(existingShards) > 0`, which is broader than necessary. The existing recovery branch in the encode arm (around the `existingECShards` block, ~line 216) is designed to fold partial leftover shards from a previously failed encode into the new task as cleanup sources. Skipping unconditionally on any existing shards made that branch dead code, regressing the recovery behavior Gemini flagged in the review of |

fix(ec): preserve source disk type across EC encoding (#9423) (#9449)
* fix(ec): carry source disk type on VolumeEcShardsMount (#9423) When EC shards land on a target whose disk type differs from the source volume's, master heartbeats wrongly reported under the target disk's type. Add source_disk_type to VolumeEcShardsMountRequest; the target server applies it to the in-memory EcVolume via SetDiskType so the mount notification and steady-state heartbeat both carry the source's disk type. Empty value falls back to the location's disk type (used by disk-scan reload paths). The override is not persisted with the volume — disk type stays an environmental property and .vif remains portable. * fix(ec): plumb source disk type through plugin worker (#9423) Add source_disk_type to ErasureCodingTaskParams (field 8; 7 reserved), populate it from the metric the detector already collects, thread it through ec_task into the MountEcShards helper, and forward it on the VolumeEcShardsMount RPC. * fix(ec): mirror source disk type plumbing in rust volume server (#9423) The volume_ec_shards_mount handler now forwards source_disk_type into mount_ec_shard → DiskLocation::mount_ec_shards. When non-empty it overrides ec_vol.disk_type (and each mounted shard's disk_type) via the new set_disk_type method; empty value keeps the location's disk type, so disk-scan reload and reconcile paths are unchanged. Also picks up two pre-existing proto drifts that 'make gen' synced from weed/pb (LockRingUpdate in master.proto, listing_cache_ttl_seconds in remote.proto). * feat(ec): bias placement toward preferred disk type (#9423) Add DiskCandidate.DiskType and PlacementRequest.PreferredDiskType. When PreferredDiskType is non-empty, SelectDestinations partitions suitable disks into matching/fallback tiers and runs the rack/server/ disk-diversity passes on the matching tier first; the fallback tier is only consulted if the matching pool can't satisfy ShardsNeeded. PlacementResult.SpilledToOtherDiskType lets callers warn on spillover. Empty PreferredDiskType keeps the existing single-pool behavior. * fix(ec): plumb source disk type into placement planner (#9423) diskInfosToCandidates now copies DiskInfo.DiskType into the placement candidate, and ecPlacementPlanner.selectDestinations forwards metric.DiskType as PreferredDiskType so EC shards land on disks matching the source volume's disk type when possible. A glog warning fires when placement had to spill to other disk types. * test(ec): integration coverage for source-disk-type plumbing (#9423) store_ec_disk_type_test exercises Store.MountEcShards end-to-end: a shard physically lives on an HDD location, MountEcShards is called with sourceDiskType="ssd", and the test asserts that the in-memory EcVolume, the mounted shard, the NewEcShardsChan notification, and the steady-state heartbeat all report under the source's disk type. A companion test pins the empty-source path so disk-scan reload keeps the location's disk type. detection_disk_type_test exercises the worker plumbing: with a cluster of nodes carrying both HDD and SSD disks, planECDestinations must place every shard on SSD when metric.DiskType="ssd"; with only one SSD node and 13 HDD nodes it must still satisfy a 10+4 layout via spillover (and log a warning). * revert(ec): drop unrelated proto drift in seaweed-volume/proto (#9423) make gen pulled two pre-existing OSS changes into the rust proto tree (LockRingUpdate / by_plugin in master.proto, listing_cache_ttl_seconds in remote.proto). Reviewers flagged it as scope creep — none of the rust EC fix references those fields. Restore both files to origin/master so this branch only touches EC-related symbols. * fix(ec placement): treat empty disk type as hdd and skip used racks on spill (#9423) partitionByDiskType used raw string comparison, so a PreferredDiskType of "hdd" never matched candidates whose DiskType is "" (the HardDriveType sentinel that weed/storage/types uses). EC encoding of an HDD source would spill onto any HDD reporting "" even when the cluster has plenty of matching capacity. Normalize both sides through normalizeDiskType, which lowercases and folds "" → "hdd", mirroring types.ToDiskType without taking a dependency on it. selectFromTier's rack-diversity pass also kept revisiting racks the preferred tier had already used when running on the fallback tier, which negated PreferDifferentRacks on spillover. Skip racks already in usedRacks so fallback placements still spread onto new racks. * fix(ec): empty-source remount must not clobber existing disk type (#9423) mount_ec_shards_with_idx_dir runs more than once per vid (RPC mount, disk-scan reload, orphan-shard reconcile). After an RPC sets the source-derived disk type, any later call passing source_disk_type="" was resetting ec_vol.disk_type back to the location's value, which reintroduces the heartbeat drift this PR is meant to fix. Only default to the location's disk type when the EC volume is fresh (no shards mounted yet); otherwise leave the recorded type alone so empty-source reloads preserve whatever the original mount RPC set. |

fix(ec): planner treats each (server, disk_id) as a distinct target (#9369) (#9371)
* fix(ec): planner treats each (server, disk_id) as a distinct target (#9369) master_pb.DataNodeInfo.DiskInfos is keyed by disk type, so a volume server with multiple physical disks of the same type collapses into a single DiskInfo. Per-disk attribution survives only inside the VolumeInfos[].DiskId / EcShardInfos[].DiskId records, and the active topology never put it back together. The EC planner saw N candidates instead of N×disks, returned a short plan, and createECTargets round-robined extra shards onto the same (server, disk_id) — colliding with the #9185 disk_id-aware ReceiveFile. Reconstruct per-physical-disk view in UpdateTopology by splitting each DiskInfo into one entry per observed disk_id, and index volumes / EC shards by their own DiskId so lookups stay aligned. Refuse to plan an EC task when fewer than totalShards distinct disks are available rather than packing shards onto the same disk. Threads dataShards/parityShards through planECDestinations, createECTargets and createECTaskParams so the helpers don't depend on the OSS 10+4 constants — keeps enterprise merges clean. * trim verbose comments * align EC param signatures with enterprise - dataShards/parityShards: uint32 → int (matches enterprise's ratio API) - drop unused multiPlan from createECTaskParams - minTotalDisks: total/parity+1 → ceil(total/parity), correct for non-default ratios Reduces merge surface when this PR lands in seaweed-enterprise. |

refactor(plugin): rename detection_interval_seconds → detection_interval_minutes (#9366)
Minutes is the natural granularity for detection cadence — every production handler already set the seconds field to a 60-multiple (17*60, 30*60, 3600, 24*60*60). Switching to minutes drops the *60 arithmetic and matches the unit conventions used elsewhere in the plugin worker forms. - Proto: AdminRuntimeDefaults + AdminRuntimeConfig.detection_interval_* field renamed. - Helpers: durationFromMinutes / minutesFromDuration alongside the existing seconds variants in plugin_scheduler.go. - Handlers: vacuum, ec_balance, balance, erasure_coding, iceberg, admin_script, s3_lifecycle now declare DetectionIntervalMinutes. - Admin: scheduler_status + types + UI templ + plugin_api.go pass through the new field; UI label and table cells switch to "min". |

refactor(worker): co-locate plugin handlers with their task packages (#9301)
* refactor(worker): co-locate plugin handlers with their task packages
Move every per-task plugin handler from weed/plugin/worker/ into the
matching weed/worker/tasks/<name>/ package, so each task owns its
detection, scheduling, execution, and plugin handler in one place.
Step 0 (within pluginworker, no behavior change): extract shared helpers
that previously lived inside individual handler files into dedicated
files and export the ones now consumed across packages.
- activity.go: BuildExecutorActivity, BuildDetectorActivity
- config.go: ReadStringConfig/Double/Int64/Bytes/StringList, MapTaskPriority
- interval.go: ShouldSkipDetectionByInterval
- volume_state.go: VolumeState + consts, FilterMetricsByVolumeState/Location
- collection_filter.go: CollectionFilterMode + consts
- volume_metrics.go: export CollectVolumeMetricsFromMasters,
MasterAddressCandidates, FetchVolumeList
- testing_senders_test.go: shared test stubs
Phase 1: move the per-task plugin handlers (and the iceberg subpackage)
into their task packages.
weed/plugin/worker/vacuum_handler.go -> weed/worker/tasks/vacuum/plugin_handler.go
weed/plugin/worker/ec_balance_handler.go -> weed/worker/tasks/ec_balance/plugin_handler.go
weed/plugin/worker/erasure_coding_handler.go -> weed/worker/tasks/erasure_coding/plugin_handler.go
weed/plugin/worker/volume_balance_handler.go -> weed/worker/tasks/balance/plugin_handler.go
weed/plugin/worker/iceberg/ -> weed/worker/tasks/iceberg/
weed/plugin/worker/handlers/handlers.go now blank-imports all five
task subpackages so their init() registrations fire.
weed/command/mini.go and the worker tests construct the handler with
vacuum.DefaultMaxExecutionConcurrency (the constant moved with the
vacuum handler).
admin_script remains in weed/plugin/worker/ because there is no
underlying weed/worker/tasks/admin_script/ package to merge with.
* refactor(worker): update test/plugin_workers imports for moved handlers
Three handler constructors moved out of pluginworker into their task
packages — update the integration test files in test/plugin_workers/
to import from the new locations:
pluginworker.NewVacuumHandler -> vacuum.NewVacuumHandler
pluginworker.NewVolumeBalanceHandler -> balance.NewVolumeBalanceHandler
pluginworker.NewErasureCodingHandler -> erasure_coding.NewErasureCodingHandler
The pluginworker import is kept where the file still uses
pluginworker.WorkerOptions / pluginworker.JobHandler.
* refactor(worker): update test/s3tables iceberg import path
The iceberg subpackage moved from weed/plugin/worker/iceberg/ to
weed/worker/tasks/iceberg/. test/s3tables/maintenance/maintenance_integration_test.go
still imported the old path, breaking S3 Tables / RisingWave / Trino /
Spark / Iceberg-catalog / STS integration test builds.
Mirrors the OSS-side fix needed by every job in the run that
transitively imports test/s3tables/maintenance.
* chore: gofmt PR-touched files
The S3 Tables Format Check job runs `gofmt -l` over weed/s3api/s3tables
and test/s3tables, then fails if anything is unformatted. Files this
PR moved or modified had import-grouping and trailing-spacing issues
introduced by perl-based renames; reformat them with gofmt -w.
Touched files:
test/plugin_workers/erasure_coding/{detection,execution}_test.go
test/s3tables/maintenance/maintenance_integration_test.go
weed/plugin/worker/handlers/handlers.go
weed/worker/tasks/{balance,ec_balance,erasure_coding,vacuum}/plugin_handler*.go
* refactor(worker): bounds-checked int conversions for plugin config values
CodeQL flagged 18 go/incorrect-integer-conversion warnings on the moved
plugin handler files: results of pluginworker.ReadInt64Config (which
ultimately calls strconv.ParseInt with bit size 64) were being narrowed
to int32/uint32/int without an upper-bound check, so a malicious or
malformed admin/worker config value could overflow the target type.
Add three helpers in weed/plugin/worker/config.go that wrap
ReadInt64Config and clamp out-of-range values back to the caller's
fallback:
ReadInt32Config (math.MinInt32 .. math.MaxInt32)
ReadUint32Config (0 .. math.MaxUint32)
ReadIntConfig (math.MinInt32 .. math.MaxInt32, platform-portable)
Update each flagged call site in the four moved task packages to use
the bounds-checked helper. For protobuf uint32 fields (volume IDs)
the variable type also becomes uint32, removing the trailing
uint32(volumeID) casts and changing the "missing volume_id" check
from `<= 0` to `== 0`.
Touched files:
weed/plugin/worker/config.go
weed/worker/tasks/balance/plugin_handler.go
weed/worker/tasks/erasure_coding/plugin_handler.go
weed/worker/tasks/vacuum/plugin_handler.go
* refactor(worker): use ReadIntConfig for clamped derive-worker-config helpers
CodeQL still flagged three call sites where ReadInt64Config was being
narrowed to int after a value-range clamp (max_concurrent_moves <= 50,
batch_size <= 100, min_server_count >= 2). The clamp is correct but
CodeQL's flow analysis didn't recognize the bound, so it flagged them
as unbounded narrowing.
Switch to ReadIntConfig (already int32-bounded by the helper) for
those three sites, drop the now-redundant int64 intermediate variables.
Also drops the now-unused `> math.MaxInt32` clamp in
ec_balance.deriveECBalanceWorkerConfig (the helper covers it).

fix(erasure_coding): surface replica delete failures from EC task (#9184) (#9187)
* test(erasure_coding): reproduce #9184 deleteOriginalVolume swallowing errors ErasureCodingTask.deleteOriginalVolume logs a warning when any replica VolumeDelete fails and then returns nil, so the EC task reports success to the admin even when a source replica survives. That stale replica lets a later detection scan re-propose the same volume and, once retried, drives the mounted-shard-truncation corruption that issue 9184 also describes. Reproducer: wire one reachable replica (succeeds) and one unreachable replica (fails) and assert the function currently returns nil. After the fix the function must surface the replica failure so the task is retried rather than marked done, and this test needs to be inverted. * fix(erasure_coding): surface replica delete failures from EC task ErasureCodingTask.deleteOriginalVolume previously logged a warning and returned nil when any VolumeDelete against a source replica failed. The EC task therefore reported overall success to the admin even when a source replica stayed on disk, which let a later detection scan propose a duplicate EC encoding of the same volume. The retry then walked the ReceiveFile path against servers that already had mounted EC shards for the volume, truncating the live shard files in place (the other half of #9184). This change returns an error describing the per-replica failures after the best-effort delete pass, so the task is marked failed instead of silently moving on. Successful deletes are still applied (per-replica progress is preserved); only the final return changes. When combined with the ReceiveFile mount-safety check, a stuck original replica now produces loud, actionable failures instead of silent corruption. Tests: - TestDeleteOriginalVolumeSurfacesReplicaFailures: asserts an error is returned and names the unreachable replica, while the reachable replica still gets deleted. - TestDeleteOriginalVolumeSucceedsWhenAllReplicasReachable: pins the happy path. |

fix(ec): generate .ecx before EC shards to prevent data inconsistency (#8972)
* fix(ec): generate .ecx before EC shards to prevent data inconsistency In VolumeEcShardsGenerate, the .ecx index was generated from .idx AFTER the EC shards were generated from .dat. If any write occurred between these two steps (e.g. WriteNeedleBlob during replica sync, which bypasses the read-only check), the .ecx would contain entries pointing to data that doesn't exist in the EC shards, causing "shard too short" and "size mismatch" errors on subsequent reads and scrubs. Fix by generating .ecx FIRST, then snapshotting datFileSize, then encoding EC shards. If a write sneaks in after .ecx generation, the EC shards contain more data than .ecx references — which is harmless (the extra data is simply not indexed). Also snapshot datFileSize before EC encoding to ensure the .vif reflects the same .dat state that .ecx was generated from. Add TestEcConsistency_WritesBetweenEncodeAndEcx that reproduces the race condition by appending data between EC encoding and .ecx generation. * fix: pass actual offset to ReadBytes, improve test quality - Pass offset.ToActualOffset() to ReadBytes instead of 0 to preserve correct error metrics and error messages within ReadBytes - Handle Stat() error in assembleFromIntervalsAllowError - Rename TestEcConsistency_DatFileGrowsDuringEncoding to TestEcConsistency_ExactLargeRowEncoding (test verifies fixed-size encoding, not concurrent growth) - Update test comment to clarify it reproduces the old buggy sequence - Fix verification loop to advance by readSize for full data coverage * fix(ec): add dat/idx consistency check in worker EC encoding The erasure_coding worker copies .dat and .idx as separate network transfers. If a write lands on the source between these copies, the .idx may have entries pointing past the end of .dat, leading to EC volumes with .ecx entries that reference non-existent shard data. Add verifyDatIdxConsistency() that walks the .idx and verifies no entry's offset+size exceeds the .dat file size. This fails the EC task early with a clear error instead of silently producing corrupt EC volumes. * test(ec): add integration test verifying .ecx/.ecd consistency TestEcIndexConsistencyAfterEncode uploads multiple needles of varying sizes (14B to 256KB), EC-encodes the volume, mounts data shards, then reads every needle back via the EC read path and verifies payload correctness. This catches any inconsistency between .ecx index entries and EC shard data. * fix(test): account for needle overhead in test volume fixture WriteTestVolumeFiles created a .dat of exactly datSize bytes but the .idx entry claimed a needle of that same size. GetActualSize adds header + checksum + timestamp overhead, so the consistency check correctly rejects this as the needle extends past the .dat file. Fix by sizing the .dat to GetActualSize(datSize) so the .idx entry is consistent with the .dat contents. * fix(test): remove flaky shard ID assertion in EC scrub test When shard 0 is truncated on disk after mount, the volume server may detect corruption via parity mismatches (shards 10-13) rather than a direct read failure on shard 0, depending on OS caching/mmap behavior. Replace the brittle shard-0-specific check with a volume ID validation. * fix(test): close upload response bodies and tighten file count assertion Wrap UploadBytes calls with ReadAllAndClose to prevent connection/fd leaks during test execution. Also tighten TotalFiles check from >= 1 to == 1 since ecSetup uploads exactly one file. |

chore: remove ~50k lines of unreachable dead code (#8913)
* chore: remove unreachable dead code across the codebase Remove ~50,000 lines of unreachable code identified by static analysis. Major removals: - weed/filer/redis_lua: entire unused Redis Lua filer store implementation - weed/wdclient/net2, resource_pool: unused connection/resource pool packages - weed/plugin/worker/lifecycle: unused lifecycle plugin worker - weed/s3api: unused S3 policy templates, presigned URL IAM, streaming copy, multipart IAM, key rotation, and various SSE helper functions - weed/mq/kafka: unused partition mapping, compression, schema, and protocol functions - weed/mq/offset: unused SQL storage and migration code - weed/worker: unused registry, task, and monitoring functions - weed/query: unused SQL engine, parquet scanner, and type functions - weed/shell: unused EC proportional rebalance functions - weed/storage/erasure_coding/distribution: unused distribution analysis functions - Individual unreachable functions removed from 150+ files across admin, credential, filer, iam, kms, mount, mq, operation, pb, s3api, server, shell, storage, topology, and util packages * fix(s3): reset shared memory store in IAM test to prevent flaky failure TestLoadIAMManagerFromConfig_EmptyConfigWithFallbackKey was flaky because the MemoryStore credential backend is a singleton registered via init(). Earlier tests that create anonymous identities pollute the shared store, causing LookupAnonymous() to unexpectedly return true. Fix by calling Reset() on the memory store before the test runs. * style: run gofmt on changed files * fix: restore KMS functions used by integration tests * fix(plugin): prevent panic on send to closed worker session channel The Plugin.sendToWorker method could panic with "send on closed channel" when a worker disconnected while a message was being sent. The race was between streamSession.close() closing the outgoing channel and sendToWorker writing to it concurrently. Add a done channel to streamSession that is closed before the outgoing channel, and check it in sendToWorker's select to safely detect closed sessions without panicking. |

fix(worker): pass compaction revision and file sizes in EC volume copy (#8835)
* fix(worker): pass compaction revision and file sizes in EC volume copy The worker EC task was sending CopyFile requests without the current compaction revision (defaulting to 0) and with StopOffset set to math.MaxInt64. After a vacuum compaction this caused the volume server to reject the copy or return stale data. Read the volume file status first and forward the compaction revision and actual file sizes so the copy is consistent with the compacted volume. * propagate erasure coding task context * fix(worker): validate volume file status and detect short copies Reject zero dat file size from ReadVolumeFileStatus — a zero-sized snapshot would produce 0-byte copies and broken EC shards. After streaming, verify totalBytes matches the expected stopOffset and return an error on short copies instead of logging success. * fix(worker): reject zero idx file size in volume status validation A non-empty dat with zero idx indicates an empty or corrupt volume. Without this guard, copyFileFromSource gets stopOffset=0, produces a 0-byte .idx, passes the short-copy check, and generateEcShardsLocally runs against a volume with no index. * fix fake plugin volume file status * fix plugin volume balance test fixtures |

Replace all duplicate implementations with imports and calls to util.NormalizeTagList. This improves code reuse and maintainability by centralizing tag normalization logic. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add PreferredTags to EC config persistence Add preferred_tags field to ErasureCodingTaskConfig protobuf with field number 5. Update GetConfigSpec to include preferred_tags field in the UI configuration schema. Add PreferredTags to ToTaskPolicy to serialize config to protobuf.

Add defensive copy in ToTaskPolicy for PreferredTags slice to match the pattern used in FromTaskPolicy, preventing external mutation of the returned TaskPolicy. 3. Add clarifying comment in buildCandidateSets explaining that the shardsNeeded <= 0 branch is a defensive check for direct callers, since selectDestinations guarantees shardsNeeded > 0. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix nil pointer dereference in parseVolumeTags Ensure all folder tags are initialized to either normalized tags or empty slices, not nil.

Make EC detection context aware (#8449)
* Make EC detection context aware * Update register.go * Speed up EC detection planning * Add tests for EC detection planner * optimizations detection.go: extracted ParseCollectionFilter (exported) and feed it into the detection loop so both detection and tracing share the same parsing/whitelisting logic; the detection loop now iterates on a sorted list of volume IDs, checks the context at every iteration, and only sets hasMore when there are still unprocessed groups after hitting maxResults, keeping runtime bounded while still scheduling planned tasks before returning the results. erasure_coding_handler.go: dropped the duplicated inline filter parsing in emitErasureCodingDetectionDecisionTrace and now reuse erasurecodingtask.ParseCollectionFilter, and the summary suffix logic now only accounts for the hasMore case that can actually happen. detection_test.go: updated the helper topology builder to use master_pb.VolumeInformationMessage (matching the current protobuf types) and tightened the cancellation/max-results tests so they reliably exercise the detection logic (cancel before calling Detection, and provide enough disks so one result is produced before the limit). * use working directory * fix compilation * fix compilation * rename * go vet * fix getenv * address comments, fix error |

Fix maintenance worker panic and add EC integration tests (#8068)
* Fix nil pointer panic in maintenance worker when receiving empty task assignment When a worker requests a task and none are available, the admin server sends an empty TaskAssignment message. The worker was attempting to log the task details without checking if the TaskId was empty, causing a nil pointer dereference when accessing taskAssign.Params.VolumeId. This fix adds a check for empty TaskId before processing the assignment, preventing worker crashes and improving stability in production environments. * Add EC integration test for admin-worker maintenance system Adds comprehensive integration test that verifies the end-to-end flow of erasure coding maintenance tasks: - Admin server detects volumes needing EC encoding - Workers register and receive task assignments - EC encoding is executed and verified in master topology - File read-back validation confirms data integrity The test uses unique absolute working directories for each worker to prevent ID conflicts and ensure stable worker registration. Includes proper cleanup and process management for reliable test execution. * Improve maintenance system stability and task deduplication - Add cross-type task deduplication to prevent concurrent maintenance operations on the same volume (EC, balance, vacuum) - Implement HasAnyTask check in ActiveTopology for better coordination - Increase RequestTask timeout from 5s to 30s to prevent unnecessary worker reconnections - Add TaskTypeNone sentinel for generic task checks - Update all task detectors to use HasAnyTask for conflict prevention - Improve config persistence and schema handling * Add GitHub Actions workflow for EC integration tests Adds CI workflow that runs EC integration tests on push and pull requests to master branch. The workflow: - Triggers on changes to admin, worker, or test files - Builds the weed binary - Runs the EC integration test suite - Uploads test logs as artifacts on failure for debugging This ensures the maintenance system remains stable and worker-admin integration is validated in CI. * go version 1.24 * address comments * Update maintenance_integration.go * support seconds * ec prioritize over balancing in tests |

opt: reduce ShardsInfo memory usage with bitmap and sorted slice (#7974)
* opt: reduce ShardsInfo memory usage with bitmap and sorted slice - Replace map[ShardId]*ShardInfo with sorted []ShardInfo slice - Add ShardBits (uint32) bitmap for O(1) existence checks - Use binary search for O(log n) lookups by shard ID - Maintain sorted order for efficient iteration - Add comprehensive unit tests and benchmarks Memory savings: - Map overhead: ~48 bytes per entry eliminated - Pointers: 8 bytes per entry eliminated - Total: ~56 bytes per shard saved Performance improvements: - Has(): O(1) using bitmap - Size(): O(log n) using binary search (was O(1), acceptable tradeoff) - Count(): O(1) using popcount on bitmap - Iteration: Faster due to cache locality * refactor: add methods to ShardBits type - Add Has(), Set(), Clear(), and Count() methods to ShardBits - Simplify ShardsInfo methods by using ShardBits methods - Improves code readability and encapsulation * opt: use ShardBits directly in ShardsCountFromVolumeEcShardInformationMessage Avoid creating a full ShardsInfo object just to count shards. Directly cast vi.EcIndexBits to ShardBits and use Count() method. * opt: use strings.Builder in ShardsInfo.String() for efficiency * refactor: change AsSlice to return []ShardInfo (values instead of pointers) This completes the memory optimization by avoiding unnecessary pointer slices and potential allocations. * refactor: rename ShardsCountFromVolumeEcShardInformationMessage to GetShardCount * fix: prevent deadlock in Add and Subtract methods Copy shards data from 'other' before releasing its lock to avoid potential deadlock when a.Add(b) and b.Add(a) are called concurrently. The previous implementation held other's lock while calling si.Set/Delete, which acquires si's lock. This could deadlock if two goroutines tried to add/subtract each other concurrently. * opt: avoid unnecessary locking in constructor functions ShardsInfoFromVolume and ShardsInfoFromVolumeEcShardInformationMessage now build shards slice and bitmap directly without calling Set(), which acquires a lock on every call. Since the object is local and not yet shared, locking is unnecessary and adds overhead. This improves performance during object construction. * fix: rename 'copy' variable to avoid shadowing built-in function The variable name 'copy' in TestShardsInfo_Copy shadowed the built-in copy() function, which is confusing and bad practice. Renamed to 'siCopy'. * opt: use math/bits.OnesCount32 and reorganize types 1. Replace manual popcount loop with math/bits.OnesCount32 for better performance and idiomatic Go code 2. Move ShardSize type definition to ec_shards_info.go for better code organization since it's primarily used there * refactor: Set() now accepts ShardInfo for future extensibility Changed Set(id ShardId, size ShardSize) to Set(shard ShardInfo) to support future additions to ShardInfo without changing the API. This makes the code more extensible as new fields can be added to ShardInfo (e.g., checksum, location, etc.) without breaking the Set API. * refactor: move ShardInfo and ShardSize to separate file Created ec_shard_info.go to hold the basic shard types (ShardInfo and ShardSize) for better code organization and separation of concerns. * refactor: add ShardInfo constructor and helper functions Added NewShardInfo() constructor and IsValid() method to better encapsulate ShardInfo creation and validation. Updated code to use the constructor for cleaner, more maintainable code. * fix: update remaining Set() calls to use NewShardInfo constructor Fixed compilation errors in storage and shell packages where Set() calls were not updated to use the new NewShardInfo() constructor. * fix: remove unreachable code in filer backup commands Removed unreachable return statements after infinite loops in filer_backup.go and filer_meta_backup.go to fix compilation errors. * fix: rename 'new' variable to avoid shadowing built-in Renamed 'new' to 'result' in MinusParityShards, Plus, and Minus methods to avoid shadowing Go's built-in new() function. * fix: update remaining test files to use NewShardInfo constructor Fixed Set() calls in command_volume_list_test.go and ec_rebalance_slots_test.go to use NewShardInfo() constructor. |

Fix reporting of EC shard sizes from nodes to masters. (#7835)
SeaweedFS tracks EC shard sizes on topology data stuctures, but this information is never
relayed to master servers :( The end result is that commands reporting disk usage, such
as `volume.list` and `cluster.status`, yield incorrect figures when EC shards are present.

Fix issue #7880: Tasks use Volume IDs instead of ip:port (#7881)
* Fix issue #7880: Tasks use Volume IDs instead of ip:port When volume servers are registered with custom IDs, tasks were attempting to connect using the ID instead of the actual ip:port address, causing connection failures. Modified task detection logic in balance, erasure coding, and vacuum tasks to resolve volume server IDs to their actual ip:port addresses using ActiveTopology information. * Use server addresses directly instead of translating from IDs Modified VolumeHealthMetrics to include ServerAddress field populated directly from topology DataNodeInfo.Address. Updated task detection logic to use addresses directly without runtime lookups. Changes: - Added ServerAddress field to VolumeHealthMetrics - Updated maintenance scanner to populate ServerAddress - Modified task detection to use ServerAddress for Node fields - Updated DestinationPlan to include TargetAddress - Removed runtime address lookups in favor of direct address usage * Address PR comments: add ServerAddress field, improve error handling - Add missing ServerAddress field to VolumeHealthMetrics struct - Add warning in vacuum detection when server not found in topology - Improve error handling in erasure coding to abort task if sources missing - Make vacuum task stricter by skipping if server not found in topology * Refactor: Extract common address resolution logic into shared utility - Created weed/worker/tasks/util/address.go with ResolveServerAddress function - Updated balance, erasure_coding, and vacuum detection to use the shared utility - Removed code duplication and improved maintainability - Consistent error handling across all task types * Fix critical issues in task address resolution - Vacuum: Require topology availability and fail if server not found (no fallback to ID) - Ensure all task types consistently fail early when topology is incomplete - Prevent creation of tasks that would fail due to missing server addresses * Address additional PR feedback - Add validation for empty addresses in ResolveServerAddress - Remove redundant serverAddress variable in vacuum detection - Improve robustness of address resolution * Improve error logging in vacuum detection - Include actual error details in log message for better diagnostics - Make error messages consistent with other task types |

Add disk-aware EC rebalancing (#7597)
* Add placement package for EC shard placement logic - Consolidate EC shard placement algorithm for reuse across shell and worker tasks - Support multi-pass selection: racks, then servers, then disks - Include proper spread verification and scoring functions - Comprehensive test coverage for various cluster topologies * Make ec.balance disk-aware for multi-disk servers - Add EcDisk struct to track individual disks on volume servers - Update EcNode to maintain per-disk shard distribution - Parse disk_id from EC shard information during topology collection - Implement pickBestDiskOnNode() for selecting best disk per shard - Add diskDistributionScore() for tie-breaking node selection - Update all move operations to specify target disk in RPC calls - Improves shard balance within multi-disk servers, not just across servers * Use placement package in EC detection for consistent disk-level placement - Replace custom EC disk selection logic with shared placement package - Convert topology DiskInfo to placement.DiskCandidate format - Use SelectDestinations() for multi-rack/server/disk spreading - Convert placement results back to topology DiskInfo for task creation - Ensures EC detection uses same placement logic as shell commands * Make volume server evacuation disk-aware - Use pickBestDiskOnNode() when selecting evacuation target disk - Specify target disk in evacuation RPC requests - Maintains balanced disk distribution during server evacuations * Rename PlacementConfig to PlacementRequest for clarity PlacementRequest better reflects that this is a request for placement rather than a configuration object. This improves API semantics. * Rename DefaultConfig to DefaultPlacementRequest Aligns with the PlacementRequest type naming for consistency * Address review comments from Gemini and CodeRabbit Fix HIGH issues: - Fix empty disk discovery: Now discovers all disks from VolumeInfos, not just from EC shards. This ensures disks without EC shards are still considered for placement. - Fix EC shard count calculation in detection.go: Now correctly filters by DiskId and sums actual shard counts using ShardBits.ShardIdCount() instead of just counting EcShardInfo entries. Fix MEDIUM issues: - Add disk ID to evacuation log messages for consistency with other logging - Remove unused serverToDisks variable in placement.go - Fix comment that incorrectly said 'ascending' when sorting is 'descending' * add ec tests * Update ec-integration-tests.yml * Update ec_integration_test.go * Fix EC integration tests CI: build weed binary and update actions - Add 'Build weed binary' step before running tests - Update actions/setup-go from v4 to v6 (Node20 compatibility) - Update actions/checkout from v2 to v4 (Node20 compatibility) - Move working-directory to test step only * Add disk-aware EC rebalancing integration tests - Add TestDiskAwareECRebalancing test with multi-disk cluster setup - Test EC encode with disk awareness (shows disk ID in output) - Test EC balance with disk-level shard distribution - Add helper functions for disk-level verification: - startMultiDiskCluster: 3 servers x 4 disks each - countShardsPerDisk: track shards per disk per server - calculateDiskShardVariance: measure distribution balance - Verify no single disk is overloaded with shards |

Erasure Coding: Ec refactoring (#7396)
* refactor: add ECContext structure to encapsulate EC parameters
- Create ec_context.go with ECContext struct
- NewDefaultECContext() creates context with default 10+4 configuration
- Helper methods: CreateEncoder(), ToExt(), String()
- Foundation for cleaner function signatures
- No behavior change, still uses hardcoded 10+4
* refactor: update ec_encoder.go to use ECContext
- Add WriteEcFilesWithContext() and RebuildEcFilesWithContext() functions
- Keep old functions for backward compatibility (call new versions)
- Update all internal functions to accept ECContext parameter
- Use ctx.DataShards, ctx.ParityShards, ctx.TotalShards consistently
- Use ctx.CreateEncoder() instead of hardcoded reedsolomon.New()
- Use ctx.ToExt() for shard file extensions
- No behavior change, still uses default 10+4 configuration
* refactor: update ec_volume.go to use ECContext
- Add ECContext field to EcVolume struct
- Initialize ECContext with default configuration in NewEcVolume()
- Update LocateEcShardNeedleInterval() to use ECContext.DataShards
- Phase 1: Always uses default 10+4 configuration
- No behavior change
* refactor: add EC shard count fields to VolumeInfo protobuf
- Add data_shards_count field (field 8) to VolumeInfo message
- Add parity_shards_count field (field 9) to VolumeInfo message
- Fields are optional, 0 means use default (10+4)
- Backward compatible: fields added at end
- Phase 1: Foundation for future customization
* refactor: regenerate protobuf Go files with EC shard count fields
- Regenerated volume_server_pb/*.go with new EC fields
- DataShardsCount and ParityShardsCount accessors added to VolumeInfo
- No behavior change, fields not yet used
* refactor: update VolumeEcShardsGenerate to use ECContext
- Create ECContext with default configuration in VolumeEcShardsGenerate
- Use ecCtx.TotalShards and ecCtx.ToExt() in cleanup
- Call WriteEcFilesWithContext() instead of WriteEcFiles()
- Save EC configuration (DataShardsCount, ParityShardsCount) to VolumeInfo
- Log EC context being used
- Phase 1: Always uses default 10+4 configuration
- No behavior change
* fmt
* refactor: update ec_test.go to use ECContext
- Update TestEncodingDecoding to create and use ECContext
- Update validateFiles() to accept ECContext parameter
- Update removeGeneratedFiles() to use ctx.TotalShards and ctx.ToExt()
- Test passes with default 10+4 configuration
* refactor: use EcShardConfig message instead of separate fields
* optimize: pre-calculate row sizes in EC encoding loop
* refactor: replace TotalShards field with Total() method
- Remove TotalShards field from ECContext to avoid field drift
- Add Total() method that computes DataShards + ParityShards
- Update all references to use ctx.Total() instead of ctx.TotalShards
- Read EC config from VolumeInfo when loading EC volumes
- Read data shard count from .vif in VolumeEcShardsToVolume
- Use >= instead of > for exact boundary handling in encoding loops
* optimize: simplify VolumeEcShardsToVolume to use existing EC context
- Remove redundant CollectEcShards call
- Remove redundant .vif file loading
- Use v.ECContext.DataShards directly (already loaded by NewEcVolume)
- Slice tempShards instead of collecting again
* refactor: rename MaxShardId to MaxShardCount for clarity
- Change from MaxShardId=31 to MaxShardCount=32
- Eliminates confusing +1 arithmetic (MaxShardId+1)
- More intuitive: MaxShardCount directly represents the limit
fix: support custom EC ratios beyond 14 shards in VolumeEcShardsToVolume
- Add MaxShardId constant (31, since ShardBits is uint32)
- Use MaxShardId+1 (32) instead of TotalShardsCount (14) for tempShards buffer
- Prevents panic when slicing for volumes with >14 total shards
- Critical fix for custom EC configurations like 20+10
* fix: add validation for EC shard counts from VolumeInfo
- Validate DataShards/ParityShards are positive and within MaxShardCount
- Prevent zero or invalid values that could cause divide-by-zero
- Fallback to defaults if validation fails, with warning log
- VolumeEcShardsGenerate now preserves existing EC config when regenerating
- Critical safety fix for corrupted or legacy .vif files
* fix: RebuildEcFiles now loads EC config from .vif file
- Critical: RebuildEcFiles was always using default 10+4 config
- Now loads actual EC config from .vif file when rebuilding shards
- Validates config before use (positive shards, within MaxShardCount)
- Falls back to default if .vif missing or invalid
- Prevents data corruption when rebuilding custom EC volumes
* add: defensive validation for dataShards in VolumeEcShardsToVolume
- Validate dataShards > 0 and <= MaxShardCount before use
- Prevents panic from corrupted or uninitialized ECContext
- Returns clear error message instead of panic
- Defense-in-depth: validates even though upstream should catch issues
* fix: replace TotalShardsCount with MaxShardCount for custom EC ratio support
Critical fixes to support custom EC ratios > 14 shards:
disk_location_ec.go:
- validateEcVolume: Check shards 0-31 instead of 0-13 during validation
- removeEcVolumeFiles: Remove shards 0-31 instead of 0-13 during cleanup
ec_volume_info.go ShardBits methods:
- ShardIds(): Iterate up to MaxShardCount (32) instead of TotalShardsCount (14)
- ToUint32Slice(): Iterate up to MaxShardCount (32)
- IndexToShardId(): Iterate up to MaxShardCount (32)
- MinusParityShards(): Remove shards 10-31 instead of 10-13 (added note about Phase 2)
- Minus() shard size copy: Iterate up to MaxShardCount (32)
- resizeShardSizes(): Iterate up to MaxShardCount (32)
Without these changes:
- Custom EC ratios > 14 total shards would fail validation on startup
- Shards 14-31 would never be discovered or cleaned up
- ShardBits operations would miss shards >= 14
These changes are backward compatible - MaxShardCount (32) includes
the default TotalShardsCount (14), so existing 10+4 volumes work as before.
* fix: replace TotalShardsCount with MaxShardCount in critical data structures
Critical fixes for buffer allocations and loops that must support
custom EC ratios up to 32 shards:
Data Structures:
- store_ec.go:354: Buffer allocation for shard recovery (bufs array)
- topology_ec.go:14: EcShardLocations.Locations fixed array size
- command_ec_rebuild.go:268: EC shard map allocation
- command_ec_common.go:626: Shard-to-locations map allocation
Shard Discovery Loops:
- ec_task.go:378: Loop to find generated shard files
- ec_shard_management.go: All 8 loops that check/count EC shards
These changes are critical because:
1. Buffer allocations sized to 14 would cause index-out-of-bounds panics
when accessing shards 14-31
2. Fixed arrays sized to 14 would truncate shard location data
3. Loops limited to 0-13 would never discover/manage shards 14-31
Note: command_ec_encode.go:208 intentionally NOT changed - it creates
shard IDs to mount after encoding. In Phase 1 we always generate 14
shards, so this remains TotalShardsCount and will be made dynamic in
Phase 2 based on actual EC context.
Without these fixes, custom EC ratios > 14 total shards would cause:
- Runtime panics (array index out of bounds)
- Data loss (shards 14-31 never discovered/tracked)
- Incomplete shard management (missing shards not detected)
* refactor: move MaxShardCount constant to ec_encoder.go
Moved MaxShardCount from ec_volume_info.go to ec_encoder.go to group it
with other shard count constants (DataShardsCount, ParityShardsCount,
TotalShardsCount). This improves code organization and makes it easier
to understand the relationship between these constants.
Location: ec_encoder.go line 22, between TotalShardsCount and MinTotalDisks
* improve: add defensive programming and better error messages for EC
Code review improvements from CodeRabbit:
1. ShardBits Guardrails (ec_volume_info.go):
- AddShardId, RemoveShardId: Reject shard IDs >= MaxShardCount
- HasShardId: Return false for out-of-range shard IDs
- Prevents silent no-ops from bit shifts with invalid IDs
2. Future-Proof Regex (disk_location_ec.go):
- Updated regex from \.ec[0-9][0-9] to \.ec\d{2,3}
- Now matches .ec00 through .ec999 (currently .ec00-.ec31 used)
- Supports future increases to MaxShardCount beyond 99
3. Better Error Messages (volume_grpc_erasure_coding.go):
- Include valid range (1..32) in dataShards validation error
- Helps operators quickly identify the problem
4. Validation Before Save (volume_grpc_erasure_coding.go):
- Validate ECContext (DataShards > 0, ParityShards > 0, Total <= MaxShardCount)
- Log EC config being saved to .vif for debugging
- Prevents writing invalid configs to disk
These changes improve robustness and debuggability without changing
core functionality.
* fmt
* fix: critical bugs from code review + clean up comments
Critical bug fixes:
1. command_ec_rebuild.go: Fixed indentation causing compilation error
- Properly nested if/for blocks in registerEcNode
2. ec_shard_management.go: Fixed isComplete logic incorrectly using MaxShardCount
- Changed from MaxShardCount (32) back to TotalShardsCount (14)
- Default 10+4 volumes were being incorrectly reported as incomplete
- Missing shards 14-31 were being incorrectly reported as missing
- Fixed in 4 locations: volume completeness checks and getMissingShards
3. ec_volume_info.go: Fixed MinusParityShards removing too many shards
- Changed from MaxShardCount (32) back to TotalShardsCount (14)
- Was incorrectly removing shard IDs 10-31 instead of just 10-13
Comment cleanup:
- Removed Phase 1/Phase 2 references (development plan context)
- Replaced with clear statements about default 10+4 configuration
- SeaweedFS repo uses fixed 10+4 EC ratio, no phases needed
Root cause: Over-aggressive replacement of TotalShardsCount with MaxShardCount.
MaxShardCount (32) is the limit for buffer allocations and shard ID loops,
but TotalShardsCount (14) must be used for default EC configuration logic.
* fix: add defensive bounds checks and compute actual shard counts
Critical fixes from code review:
1. topology_ec.go: Add defensive bounds checks to AddShard/DeleteShard
- Prevent panic when shardId >= MaxShardCount (32)
- Return false instead of crashing on out-of-range shard IDs
2. command_ec_common.go: Fix doBalanceEcShardsAcrossRacks
- Was using hardcoded TotalShardsCount (14) for all volumes
- Now computes actual totalShardsForVolume from rackToShardCount
- Fixes incorrect rebalancing for volumes with custom EC ratios
- Example: 5+2=7 shards would incorrectly use 14 as average
These fixes improve robustness and prepare for future custom EC ratios
without changing current behavior for default 10+4 volumes.
Note: MinusParityShards and ec_task.go intentionally NOT changed for
seaweedfs repo - these will be enhanced in seaweed-enterprise repo
where custom EC ratio configuration is added.
* fmt
* style: make MaxShardCount type casting explicit in loops
Improved code clarity by explicitly casting MaxShardCount to the
appropriate type when used in loop comparisons:
- ShardId comparisons: Cast to ShardId(MaxShardCount)
- uint32 comparisons: Cast to uint32(MaxShardCount)
Changed in 5 locations:
- Minus() loop (line 90)
- ShardIds() loop (line 143)
- ToUint32Slice() loop (line 152)
- IndexToShardId() loop (line 219)
- resizeShardSizes() loop (line 248)
This makes the intent explicit and improves type safety readability.
No functional changes - purely a style improvement.

Admin: refactoring active topology (#7073)
* refactoring * add ec shard size * address comments * passing task id There seems to be a disconnect between the pending tasks created in ActiveTopology and the TaskDetectionResult returned by this function. A taskID is generated locally and used to create pending tasks via AddPendingECShardTask, but this taskID is not stored in the TaskDetectionResult or passed along in any way. This makes it impossible for the worker that eventually executes the task to know which pending task in ActiveTopology it corresponds to. Without the correct taskID, the worker cannot call AssignTask or CompleteTask on the master, breaking the entire task lifecycle and capacity management feature. A potential solution is to add a TaskID field to TaskDetectionResult and worker_pb.TaskParams, ensuring the ID is propagated from detection to execution. * 1 source multiple destinations * task supports multi source and destination * ec needs to clean up previous shards * use erasure coding constants * getPlanningCapacityUnsafe getEffectiveAvailableCapacityUnsafe should return StorageSlotChange for calculation * use CanAccommodate to calculate * remove dead code * address comments * fix Mutex Copying in Protobuf Structs * use constants * fix estimatedSize The calculation for estimatedSize only considers source.EstimatedSize and dest.StorageChange, but omits dest.EstimatedSize. The TaskDestination struct has an EstimatedSize field, which seems to be ignored here. This could lead to an incorrect estimation of the total size of data involved in tasks on a disk. The loop should probably also include estimatedSize += dest.EstimatedSize. * at.assignTaskToDisk(task) * refactoring * Update weed/admin/topology/internal.go Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> * fail fast * fix compilation * Update weed/worker/tasks/erasure_coding/detection.go Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> * indexes for volume and shard locations * dedup with ToVolumeSlots * return an additional boolean to indicate success, or an error * Update abstract_sql_store.go * fix * Update weed/worker/tasks/erasure_coding/detection.go Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> * Update weed/admin/topology/task_management.go Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> * faster findVolumeDisk * Update weed/worker/tasks/erasure_coding/detection.go Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update weed/admin/topology/storage_slot_test.go Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * refactor * simplify * remove unused GetDiskStorageImpact function * refactor * add comments * Update weed/admin/topology/storage_impact.go Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> * Update weed/admin/topology/storage_slot_test.go Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> * Update storage_impact.go * AddPendingTask The unified AddPendingTask function now serves as the single entry point for all task creation, successfully consolidating the previously separate functions while maintaining full functionality and improving code organization. --------- Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> |
