fix(volume_server): load orphan EC shards across disks on startup (#9212) (#9244)
* fix(volume_server): load orphan EC shards across disks on startup (#9212) When ec.balance / ec.rebuild copies an EC shard onto a destination node without also pinning subsequent shards to the disk that holds .ecx, the shard ends up on a different physical disk than its index files. The per-disk loadAllEcShards has no visibility into other DiskLocations on the same store, so those orphan shards were silently left out of ecVolumes and never reported to master — volume.list showed partial counts, and ec.rebuild reported the volume as unrepairable even though all shards were physically present. After every DiskLocation finishes its initial pass, sweep the store for shard files that are on disk but not yet in any EcVolume, look up the .ecx-owning sibling disk, and load each shard against its physical disk with dirIdx pointing at the sibling. Each shard is still registered on its own disk's ecVolumes map so heartbeat reporting carries the right DiskId per shard (master fix #9219 already aggregates per-disk messages correctly). Also fall back to dirIdx for .vif lookup when dir != dirIdx, so the reconciliation path doesn't write a stub .vif on the shard disk and lose the real EC config and datFileSize. * fix(volume_server): track actual .ecx dir in cross-disk reconcile indexEcxOwners scans both IdxDirectory and Directory to find each volume's .ecx — the second scan covers the legacy case where index files were written into the data dir before -dir.idx was configured (removeEcVolumeFiles already accounts for this in disk_location_ec.go). But the returned map dropped which directory matched, and reconcile unconditionally passed owner.IdxDirectory to loadEcShardsWithIdxDir. When the owner's .ecx is in Directory and IdxDirectory != Directory (server later re-configured with -dir.idx pointing at a fresh path), NewEcVolume opens IdxDirectory/.ecx → ENOENT, retries the same-disk fallback at dataBaseFileName+.ecx — but dataBaseFileName uses the *orphan* disk's data dir, not the owner's, so it ENOENTs again and the orphan shards stay unloaded. Track which scan dir matched in indexEcxOwners and pass it through. Adds TestLoadEcShardsWhenOwnerEcxIsInDataDir as the regression. Reported in PR #9244 review by @gemini-code-assist and @coderabbitai. * refactor(storage): thread dataShardCount as a parameter into calculateExpectedShardSize The helper used erasure_coding.DataShardsCount directly, but tests in store_ec_orphan_shard_test.go save .vif with a local dataShards=10 constant. If the package default ever diverged from 10 (e.g. an enterprise build), the test would write a .vif for one layout while sizing shard files for another and silently break. Take dataShardCount as a parameter. Existing callers (validateEcVolume + size-validation tests + real-world tests) pass erasure_coding.DataShardsCount unchanged. The orphan-shard tests pass the same dataShards local they save into .vif, so the persisted shape and the on-disk shape stay consistent. Reported in PR #9244 review by @coderabbitai. |

fix(ec): honor disk_id in ReceiveFile so EC shards respect admin placement (#9184) (#9185)
* test(volume_server): reproduce #9184 EC ReceiveFile disk-placement bug The plugin-worker EC task sends shards via ReceiveFile, which picks Locations[0] as the target directory regardless of the admin planner's TargetDisk assignment. ReceiveFileInfo has no disk_id field, so there is no wire channel to honor the plan. Adds StartSingleVolumeClusterWithDataDirs to the integration framework so tests can launch a volume server with N data directories. The new repro asserts the current (buggy) behavior: sending three distinct EC shards via ReceiveFile leaves all three files in dir[0] and the other dirs empty. When the fix adds disk_id to ReceiveFileInfo, this assertion must flip to verify the planned placement is respected. * fix(ec): honor disk_id in ReceiveFile so EC shards respect admin placement Before this change, VolumeServer.ReceiveFile for EC shards always selected the first HDD location (Locations[0]). The plugin-worker EC task had no way to pass the admin planner's per-shard disk assignment — ReceiveFileInfo carried no disk_id field — so every received EC shard piled onto a single disk per destination server. On multi-disk servers this caused uneven load (one disk absorbing all EC shard I/O), frequent ENOSPC retries, and a growing EC backlog under sustained ingest (see issue #9184). Changes: - proto: add disk_id to ReceiveFileInfo, mirroring VolumeEcShardsCopyRequest.disk_id. - worker: DistributeEcShards tracks the planner-assigned disk per shard; sendShardFileToDestination forwards that disk id. Metadata files (ecx/ecj/vif) inherit the disk of the first data shard targeting the same node so they land next to the shards. - server: ReceiveFile honors disk_id when > 0 with bounds validation; disk_id=0 (unset) falls back to the same auto-selection pattern as VolumeEcShardsCopy (prefer disk that already has shards for this volume, then any HDD with free space, then any location with free space). Tests updated: - TestReceiveFileEcShardHonorsDiskID asserts three shards sent with disk_id={1,2,0} land on data dirs 1, 2, and 0 respectively. - TestReceiveFileEcShardRejectsInvalidDiskID pins the out-of-range disk_id rejection path. * fix(volume-rust): honor disk_id in ReceiveFile for EC shards Mirror the Go-side change: when disk_id > 0 place the EC shard on the requested disk; when unset, auto-select with the same preference order as volume_ec_shards_copy (disk already holding shards, then any HDD, then any disk). * fix(volume): compare disk_id as uint32 to avoid 32-bit overflow On 32-bit Go builds `int(fileInfo.DiskId) >= len(Locations)` can wrap a high-bit uint32 to a negative int, bypassing the bounds check before the index operation. Compare in the uint32 domain instead. * test(ec): fail invalid-disk_id test on transport error Previously a transport-level error from CloseAndRecv silently passed the test by returning early, masking any real gRPC failure. Fail loudly so only the structured ReceiveFileResponse rejection path counts as a pass. * docs(test): explain why DiskId=0 auto-selects dir 0 in EC placement test Documents the load-bearing assumption that shards are never mounted in this test, so loc.FindEcVolume always returns false and auto-select falls through to the first HDD. Saves future readers from re-deriving the expected directory for the DiskId=0 case. * fix(test): preserve baseDir/volume path for single-dir clusters StartSingleVolumeClusterWithDataDirs started naming the data directory volume0 even in the dataDirCount=1 case, which broke Scrub tests that reach into baseDir/volume via CorruptDatFile / CorruptEcShardFile / CorruptEcxFile. Keep the legacy name for single-dir clusters; only use the indexed "volumeN" layout when multiple disks are requested. |

fix(s3/shell): factor EC volumes into bucket size metrics and collection.list (#9182)
* fix(s3/shell): include EC volumes in bucket size metrics and collection.list S3 bucket size metrics exported to Prometheus (and fed through stats.UpdateBucketSizeMetrics) are computed by collectCollectionInfoFromTopology, which only walked diskInfo.VolumeInfos. As soon as a volume was encoded to EC it dropped out of every aggregate, so Grafana showed bucket sizes shrinking while physical disk usage kept climbing. The shell helper collectCollectionInfo — used by collection.list and s3.bucket.quota.enforce — had the same gap, with the EC branch left as a commented-out TODO. Fold EC shards into both paths using the same approach the admin dashboard already uses (PR #9093): - PhysicalSize / Size sum across shard holders: EC shards are node-local (not replicas), so per-node TotalSize() and MinusParityShards().TotalSize() sum to the whole-volume physical and logical sizes respectively. - FileCount is deduped via max across reporters (every shard holder reports the same .ecx count; a slow node with a not-yet-loaded .ecx reports 0 and must not pin the aggregate). - DeleteCount is summed (each delete tombstones exactly one node's .ecj). - VolumeCount increments once per unique EC volume id. Adds regression tests covering pure-EC, mixed regular+EC, and the slow-reporter FileCount dedupe case. Refs #9086 * Address PR review feedback: EC size helpers, composite key, VolumeCount dedupe - Add EcShardsTotalSize / EcShardsDataSize helpers in the erasure_coding package that walk the shard bitmap directly instead of materializing a ShardsInfo and copying it via MinusParityShards(). Keeps the DataShardsCount dependency encapsulated in one place and avoids the per-shard allocation/copy overhead in the metrics hot path. - Switch shell collectCollectionInfo ecVolumes map to a composite {collection, volumeId} key, matching the bucket_size_metrics collector and defending against any cross-collection volume id aliasing. - Dedupe VolumeCount in shell addToCollection by volume id so regular volumes aren't counted once per replica presence. Aligns the shell's collection.list output with the S3 metrics collector and the EC branch, all of which now report logical volume counts. - Add unit tests for the new helpers and for the regular-volume VolumeCount dedupe. * Parameterize EcShardsDataSize with dataShards for custom EC ratios Add a dataShards parameter to EcShardsDataSize so forks with per-volume ratio metadata (e.g. the enterprise data_shards field carried on an extended VolumeEcShardInformationMessage) can pass the configured value and get accurate logical sizes under custom EC policies like 6+3 or 16+6. Passing 0 or a negative value falls back to the upstream DataShardsCount default, which is correct for the fixed 10+4 layout — so OSS callers in s3api and shell pass 0 and keep their current behavior. Added table cases covering the custom 6+3 and 16+6 paths so the parameterization is pinned by tests. |

admin: report file and delete counts for EC volumes (#9060)
* admin: report file and delete counts for EC volumes The admin bucket size fix (#9058) left object counts at zero for EC-encoded data because VolumeEcShardInformationMessage carried no file count. Billing/monitoring dashboards therefore still under-report objects once a bucket is EC-encoded. Thread file_count and delete_count end-to-end: - Add file_count/delete_count to VolumeEcShardInformationMessage (proto fields 8 and 9) and regenerate master_pb. - Compute them lazily on volume servers by walking the .ecx index once per EcVolume, cache on the struct, and keep the cache in sync inside DeleteNeedleFromEcx (distinguishing live vs already-tombstoned entries so idempotent deletes do not drift the counts). - Populate the new proto fields from EcVolume.ToVolumeEcShardInformationMessage and carry them through the master-side EcVolumeInfo / topology sync. - Aggregate in admin collectCollectionStats, deduping per volume id: every node holding shards of an EC volume reports the same counts, so summing across nodes would otherwise multiply the object count by the number of shard holders. Regression tests cover the initial .ecx walk, live/tombstoned delete bookkeeping (including idempotent and missing-key cases), and the admin dedup path for an EC volume reported by multiple nodes. * ec: include .ecj journal in EcVolume delete count The initial delete count only reflected .ecx tombstones, missing any needle that was journaled in .ecj but not yet folded into .ecx — e.g. on partial recovery. Expand initCountsLocked to take the union of .ecx tombstones and .ecj journal entries, deduped by needle id, so: - an id that is both tombstoned in .ecx and listed in .ecj counts once - a duplicate .ecj entry counts once - an .ecj id with a live .ecx entry is counted as deleted (not live) - an .ecj id with no matching .ecx entry is still counted Covered by TestEcVolumeFileAndDeleteCountEcjUnion. * ec: report delete count authoritatively and tombstone once per delete Address two issues with the previous EcVolume file/delete count work: 1. The delete count was computed lazily on first heartbeat and mixed in a .ecj-union fallback to "recover" partial state. That diverged from how regular volumes report counts (always live from the needle map) and had drift cases when .ecj got reconciled. Replace with an eager walk of .ecx at NewEcVolume time, maintained incrementally on every DeleteNeedleFromEcx call. Semantics now match needle_map_metric: FileCount is the total number of needles ever recorded in .ecx (live + tombstoned), DeleteCount is the tombstones — so live = FileCount - DeleteCount. Drop the .ecj-union logic entirely. 2. A single EC needle delete fanned out to every node holding a replica of the primary data shard and called DeleteNeedleFromEcx on each, which inflated the per-volume delete total by the replica factor. Rewrite doDeleteNeedleFromRemoteEcShardServers to try replicas in order and stop at the first success (one tombstone per delete), and only fall back to other shards when the primary shard has no home (ErrEcShardMissing sentinel), not on transient RPC errors. Admin aggregation now folds EC counts correctly: FileCount is deduped per volume id (every shard holder has an identical .ecx) and DeleteCount is summed across nodes (each delete tombstones exactly one node). Live object count = deduped FileCount - summed DeleteCount. Tests updated to match the new semantics: - EC volume counts seed FileCount as total .ecx entries (live + tombstoned), DeleteCount as tombstones. - DeleteNeedleFromEcx keeps FileCount constant and increments DeleteCount only on live->tombstone transitions. - Admin dedup test uses distinct per-node delete counts (5 + 3 + 2) to prove they're summed, while FileCount=100 is applied once. * ec: test fixture uses real vid; admin warns on skewed ec counts - writeFixture now builds the .ecx/.ecj/.ec00/.vif filenames from the actual vid passed in, instead of hardcoding "_1". The existing tests all use vid=1 so behaviour is unchanged, but the helper no longer silently diverges from its documented parameter. - collectCollectionStats logs a glog warning when an EC volume's summed delete count exceeds its deduped file count, surfacing the anomaly (stale heartbeat, counter drift, etc.) instead of silently dropping the volume from the object count. * ec: derive file/delete counts from .ecx/.ecj file sizes seedCountsFromEcx walked the full .ecx index at volume load, which is wasted work: .ecx has fixed-size entries (NeedleMapEntrySize) and .ecj has fixed-size deletion records (NeedleIdSize), so both counts are pure file-size arithmetic. fileCount = ecxFileSize / NeedleMapEntrySize deleteCount = ecjFileSize / NeedleIdSize Rip out the cached counters, countsLock, seedCountsFromEcx, and the recordDelete helper. Track ecjFileSize directly on the EcVolume struct, seed it from Stat() at load, and bump it on every successful .ecj append inside DeleteNeedleFromEcx under ecjFileAccessLock. Skip the .ecj write entirely when the needle is already tombstoned so the derived delete count stays idempotent on repeat deletes. Heartbeats now compute counts in O(1). Tests updated: the initial fixture pre-populates .ecj with two ids to verify the file-size derivation end-to-end, and the delete test keeps its idempotent-re-delete / missing-needle invariants (unchanged externally, now enforced by the early return rather than a cache guard). * ec: sync Rust volume server with Go file/delete count semantics Mirror the Go-side EC file/delete count work in the Rust volume server so mixed Go/Rust clusters report consistent bucket object counts in the admin dashboard. - Add file_count (8) and delete_count (9) to the Rust copy of VolumeEcShardInformationMessage (seaweed-volume/proto/master.proto). - EcVolume gains ecj_file_size, seeded from the journal's metadata on open and bumped inside journal_delete on every successful append. - file_and_delete_count() returns counts derived in O(1) from ecx_file_size / NEEDLE_MAP_ENTRY_SIZE and ecj_file_size / NEEDLE_ID_SIZE, matching Go's FileAndDeleteCount. - to_volume_ec_shard_information_messages populates the new proto fields instead of defaulting them to zero. - mark_needle_deleted_in_ecx now returns a DeleteOutcome enum (NotFound / AlreadyDeleted / Tombstoned) so journal_delete can skip both the .ecj append and the size bump when the needle is missing or already tombstoned, keeping the derived delete_count idempotent on repeat or no-op deletes. - Rust's EcVolume::new no longer replays .ecj into .ecx on load. Go's RebuildEcxFile is only called from specific decode/rebuild gRPC handlers, not on volume open, and replaying on load was hiding the deletion journal from the new file-size-derived delete counter. rebuild_ecx_from_journal is kept as dead_code for future decode paths that may want the same replay semantics. Also clean up the Go FileAndDeleteCount to drop unnecessary runtime guards against zero constants — NeedleMapEntrySize and NeedleIdSize are compile-time non-zero. test_ec_volume_journal updated to pre-populate the .ecx with the needles it deletes, and extended to verify that repeat and missing-id deletes do not drift the derived counts. * ec: document enterprise-reserved proto field range on ec shard info Both OSS master.proto copies now note that fields 10-19 are reserved for future upstream additions while 20+ are owned by the enterprise fork. Enterprise already pins data_shards/parity_shards at 20/21, so keeping OSS additions inside 8-19 avoids wire-level collisions for mixed deployments. * ec(rust): resolve .ecx/.ecj helpers from ecx_actual_dir ecx_file_name() and ecj_file_name() resolved from self.dir_idx, but new() opens the actual files from ecx_actual_dir (which may fall back to the data dir when the idx dir does not contain the index). After a fallback, read_deleted_needles() and rebuild_ecx_from_journal() would read/rebuild the wrong (nonexistent) path while heartbeats reported counts from the file actually in use — silently dropping deletes. Point idx_base_name() at ecx_actual_dir, which is initialized to dir_idx and only diverges after a successful fallback, so every call site agrees with the file new() has open. The pre-fallback call in new() (line 142) still returns the dir_idx path because ecx_actual_dir == dir_idx at that point. Update the destroy() sweep to build the dir_idx cleanup paths explicitly instead of leaning on the helpers, so post-fallback stale files in the idx dir are still removed. * ec: reset ecj size after rebuild; rollback ecx tombstone on ecj failure Two EC delete-count correctness fixes applied symmetrically to Go and Rust volume servers. 1. rebuild_ecx_from_journal (Rust) now sets ecj_file_size = 0 after recreating the empty journal, matching the on-disk truth. Previously the cached size still reflected the pre-rebuild journal and file_and_delete_count() would keep reporting stale delete counts. The Go side has no equivalent bug because RebuildEcxFile runs in an offline helper that does not touch an EcVolume struct. 2. DeleteNeedleFromEcx / journal_delete used to tombstone the .ecx entry before writing the .ecj record. If the .ecj append then failed, the needle was permanently marked deleted but the heartbeat-reported delete_count never advanced (it is derived from .ecj file size), and a retry would see AlreadyDeleted and early- return, leaving the drift permanent. Both languages now capture the entry's file offset and original size bytes during the mark step, attempt the .ecj append, and on failure roll the .ecx tombstone back by writing the original size bytes at the known offset. A rollback that itself errors is logged (glog / tracing) but cannot re-sync the files — this is the same failure mode a double disk error would produce, and is unavoidable without a full on-disk transaction log. Go: wrap MarkNeedleDeleted in a closure that captures the file offset into an outer variable, then pass the offset + oldSize to the new rollbackEcxTombstone helper on .ecj seek/write errors. Rust: DeleteOutcome::Tombstoned now carries the size_offset and a [u8; SIZE_SIZE] copy of the pre-tombstone size field. journal_delete destructures on Tombstoned and calls restore_ecx_size on .ecj append failure. * test(ec): widen admin /health wait to 180s for cold CI TestEcEndToEnd starts master, 14 volume servers, filer, 2 workers and admin in sequence, then waited only 60s for admin's HTTP server to come up. On cold GitHub runners the tail of the earlier subprocess startups eats most of that budget and the wait occasionally times out (last hit on run 24374773031). The local fast path is still ~20s total, so the bump only extends the timeout ceiling, not the happy path. * test(ec): fork volume servers in parallel in TestEcEndToEnd startWeed is non-blocking (just cmd.Start()), so the per-process fork + mkdir + log-file-open overhead for 14 volume servers was serialized for no reason. On cold CI disks that overhead stacks up and eats into the subsequent admin /health wait, which is how run 24374773031 flaked. Wrap the volume-server loop in a sync.WaitGroup and guard runningCmds with a mutex so concurrent appends are safe. startWeed still calls t.Fatalf on failure, which is fine from a goroutine for a fatal test abort; the fail-fast isn't something we rely on for precise ordering. * ec: fsync ecx before ecj, truncate on failure, harden rebuild Four correctness fixes covering both volume servers. 1. Durability ordering (Go + Rust). After marking the .ecx tombstone we now fsync .ecx before touching .ecj, so a crash between the two files cannot leave the journal with an entry for a needle whose tombstone is still sitting in page cache. Once the fsync returns, the tombstone is the source of truth: reads see "deleted", delete_count may under-count by one (benign, idempotent retries) but never over-reports. If the fsync itself fails we restore the original size bytes and surface the error. The .ecj append is then followed by its own Sync so the reported delete_count matches the on-disk journal once the write returns. 2. .ecj truncation on append failure. write_all may have extended the journal on disk before sync_all / Sync errors out, leaving the cached ecj_file_size out of sync with the physical length and drifting delete_count permanently after restart. Both languages now capture the pre-append size, truncate the file back via set_len / Truncate on any write or sync failure, and only then restore the .ecx tombstone. Truncation errors are logged — same-fd length resets cannot realistically fail — but cannot themselves re-sync the files. 3. Atomic rebuild_ecx_from_journal (Rust, dead code today but wired up on any future decode path). Previously a failed mark_needle_deleted_in_ecx call was swallowed with `let _ = ...` and the journal was still removed, silently losing tombstones. We now bubble up any non-NotFound error, fsync .ecx after the whole replay succeeds, and only then drop and recreate .ecj. NotFound is still ignored (expected race between delete and encode). 4. Missing-.ecx hardening (Rust). mark_needle_deleted_in_ecx used to return Ok(NotFound) when self.ecx_file was None, hiding a closed or corrupt volume behind what looks like an idempotent no-op. It now returns an io::Error carrying the volume id so callers (e.g. journal_delete) fail loudly instead. Existing Go and Rust EC test suites stay green. * ec: make .ecx immutable at runtime; track deletes in memory + .ecj Refactors both volume servers so the sealed sorted .ecx index is never mutated during normal operation. Runtime deletes are committed to the .ecj deletion journal and tracked in an in-memory deleted-needle set; read-path lookups consult that set to mask out deleted ids on top of the immutable .ecx record. Mirrors the intended design on both Go and Rust sides. EcVolume gains a `deletedNeedles` / `deleted_needles` set seeded from .ecj in NewEcVolume / EcVolume::new. DeleteNeedleFromEcx / journal_delete: 1. Looks the needle up read-only in .ecx. 2. Missing needle -> no-op. 3. Pre-existing .ecx tombstone (from a prior decode/rebuild) -> mirror into the in-memory set, no .ecj append. 4. Otherwise append the id to .ecj, fsync, and only then publish the id into the set. A partial write is truncated back to the pre-append length so the on-disk journal and the in-memory set cannot drift. FindNeedleFromEcx / find_needle_from_ecx now return TombstoneFileSize when the id is in the in-memory set, even though the bytes on disk still show the original size. FileAndDeleteCount: fileCount = .ecx size / NeedleMapEntrySize (unchanged) deleteCount = len(deletedNeedles) (was: .ecj size / NeedleIdSize) The RebuildEcxFile / rebuild_ecx_from_journal decode-time helpers still fold .ecj into .ecx — that is the one place tombstones land in the physical index, and it runs offline on closed files. Rust's rebuild helper now also clears the in-memory set when it succeeds. Dead code removed on the Rust side: `DeleteOutcome`, `mark_needle_deleted_in_ecx`, `restore_ecx_size`. Go drops the runtime `rollbackEcxTombstone` path. Neither helper was needed once .ecx stopped being a runtime mutation target. TestEcVolumeSyncEnsuresDeletionsVisible (issue #7751) is rewritten as TestEcVolumeDeleteDurableToJournal, which exercises the full durability chain: delete -> .ecj fsync -> FindNeedleFromEcx masks via the in-memory set -> raw .ecx bytes are *unchanged* -> Close + RebuildEcxFile folds the journal into .ecx -> raw bytes now show the tombstone, as CopyFile in the decode path expects. |

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. |

fix(ec): off-by-one in nLargeBlockRows causes EC read corruption (#8957)
* fix(ec): off-by-one in nLargeBlockRows causes EC read corruption (#8947) The nLargeBlockRows formula in locateOffset used (shardDatSize-1)/largeBlockLength, which produces an off-by-one error when shardDatSize is an exact multiple of largeBlockLength (e.g. a 30GB volume with 10 data shards = 3GB per shard). This causes needles in the last large block row to be mislocated as small blocks, reading from completely wrong shard positions and returning garbage data. Fix: remove the -1 from locateOffset and only apply it in the ecdFileSize fallback path (old volumes without datFileSize in .vif), where it's needed to handle the ambiguous case conservatively. Also fix ReadEcShardNeedle to pass offset=0 to ReadBytes, consistent with the scrub path, since the bytes buffer already starts at position 0. * fix: add volume context to EC read errors, remove contextless glog The glog.Errorf in ReadBytes logged "entry not found" without any volume ID, making it impossible to identify which volume was affected. Remove this contextless log and instead add volume ID, needle ID, offset, and size to the error returned from the EC read path. The EC scrub callers already wrap errors with volume context. |

Process .ecj deletions during EC decode and vacuum decoded volume (#8863)
* Process .ecj deletions during EC decode and vacuum decoded volume (#8798) When decoding EC volumes back to normal volumes, deletions recorded in the .ecj journal were not being applied before computing the dat file size or checking for live needles. This caused the decoded volume to include data for deleted files and could produce false positives in the all-deleted check. - Call RebuildEcxFile before HasLiveNeedles/FindDatFileSize in VolumeEcShardsToVolume so .ecj deletions are merged into .ecx first - Vacuum the decoded volume after mounting in ec.decode to compact out deleted needle data from the .dat file - Add integration tests for decoding with non-empty .ecj files * storage: add offline volume compaction helper Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * ec: compact decoded volumes before deleting shards Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * ec: address PR review comments - Fall back to data directory for .ecx when idx directory lacks it - Make compaction failure non-fatal during EC decode - Remove misleading "buffer: 10%" from space check error message * ec: collect .ecj from all shard locations during decode Each server's .ecj only contains deletions for needles whose data resides in shards held by that server. Previously, sources with no new data shards to contribute were skipped entirely, losing their .ecj deletion entries. Now .ecj is always appended from every shard location so RebuildEcxFile sees the full set of deletions. * ec: add integration tests for .ecj collection during decode TestEcDecodePreservesDeletedNeedles: verifies that needles deleted via VolumeEcBlobDelete are excluded from the decoded volume. TestEcDecodeCollectsEcjFromPeer: regression test for the fix in collectEcShards. Deletes a needle only on a peer server that holds no new data shards, then verifies the deletion survives decode via .ecj collection. * ec: address review nits in decode and tests - Remove double error wrapping in mountDecodedVolume - Check VolumeUnmount error in peer ecj test - Assert 404 specifically for deleted needles, fail on 5xx --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> |

fix(ec): gather shards from all disk locations before rebuild (#8633)
* fix(ec): gather shards from all disk locations before rebuild (#8631)
Fix "too few shards given" error during ec.rebuild on multi-disk volume
servers. The root cause has two parts:
1. VolumeEcShardsRebuild only looked at a single disk location for shard
files. On multi-disk servers, the existing local shards could be on one
disk while copied shards were placed on another, causing the rebuild to
see fewer shards than actually available.
2. VolumeEcShardsCopy had a DiskId condition (req.DiskId == 0 &&
len(vs.store.Locations) > 0) that was always true, making the
FindFreeLocation fallback dead code. This meant copies always went to
Locations[0] regardless of where existing shards were.
Changes:
- VolumeEcShardsRebuild now finds the location with the most shards,
then gathers shard files from other locations via hard links (or
symlinks for cross-device) before rebuilding. Gathered files are
cleaned up after rebuild.
- VolumeEcShardsCopy now only uses Locations[DiskId] when DiskId > 0
(explicitly set). Otherwise, it prefers the location that already has
the EC volume, falling back to HDD then any free location.
- generateMissingEcFiles now logs shard counts and provides a clear
error message when not enough shards are found, instead of passing
through to the opaque reedsolomon "too few shards given" error.
* fix(ec): update test to match skip behavior for unrepairable volumes
The test expected an error for volumes with insufficient shards, but

ec: fall back to data dir when ecx file not found in idx dir (#8541)
* ec: fall back to data dir when ecx file not found in idx dir (#8540) When -dir.idx is configured after EC encoding, the .ecx/.ecj files remain in the data directory. NewEcVolume now falls back to the data directory when the index file is not found in dirIdx. * ec: add fallback logging and improved error message for ecx lookup * ec: preserve configured dirIdx, track actual ecx location separately The previous fallback set ev.dirIdx = dir when finding .ecx in the data directory, which corrupted IndexBaseFileName() for future writes (e.g., WriteIdxFileFromEcIndex during EC-to-volume conversion would write the .idx file to the data directory instead of the configured index directory). Introduce ecxActualDir to track where .ecx/.ecj were actually found, used only by FileName() for cleanup/destroy. IndexBaseFileName() continues to use the configured dirIdx for new file creation. * ec: check both idx and data dirs for .ecx in all cleanup and lookup paths When -dir.idx is configured after EC encoding, .ecx/.ecj files may reside in the data directory. Several code paths only checked l.IdxDirectory, causing them to miss these files: - removeEcVolumeFiles: now removes .ecx/.ecj from both directories - loadExistingVolume: ecx existence check falls back to data dir - deleteEcShardIdsForEachLocation: ecx existence check and cleanup both cover the data directory - VolumeEcShardsRebuild: ecx lookup falls back to data directory so RebuildEcxFile operates on the correct file |

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

fix: EC rebalance fails with replica placement 000 (#7812)
* fix: EC rebalance fails with replica placement 000 This PR fixes several issues with EC shard distribution: 1. Pre-flight check before EC encoding - Verify target disk type has capacity before encoding starts - Prevents encoding shards only to fail during rebalance - Shows helpful error when wrong diskType is specified (e.g., ssd when volumes are on hdd) 2. Fix EC rebalance with replica placement 000 - When DiffRackCount=0, shards should be distributed freely across racks - The '000' placement means 'no volume replication needed' because EC provides redundancy - Previously all racks were skipped with error 'shards X > replica placement limit (0)' 3. Add unit tests for EC rebalance slot calculation - TestECRebalanceWithLimitedSlots: documents the limited slots scenario - TestECRebalanceZeroFreeSlots: reproduces the 0 free slots error 4. Add Makefile for manual EC testing - make setup: start cluster and populate data - make shell: open weed shell for EC commands - make clean: stop cluster and cleanup * fix: default -rebalance to true for ec.encode The -rebalance flag was defaulting to false, which meant ec.encode would only print shard moves but not actually execute them. This is a poor default since the whole point of EC encoding is to distribute shards across servers for fault tolerance. Now -rebalance defaults to true, so shards are actually distributed after encoding. Users can use -rebalance=false if they only want to see what would happen without making changes. * test/erasure_coding: improve Makefile safety and docs - Narrow pkill pattern for volume servers to use TEST_DIR instead of port pattern, avoiding accidental kills of unrelated SeaweedFS processes - Document external dependencies (curl, jq) in header comments * shell: refactor buildRackWithEcShards to reuse buildEcShards Extract common shard bit construction logic to avoid duplication between buildEcShards and buildRackWithEcShards helper functions. * shell: update test for EC replication 000 behavior When DiffRackCount=0 (replication "000"), EC shards should be distributed freely across racks since erasure coding provides its own redundancy. Update test expectation to reflect this behavior. * erasure_coding: add distribution package for proportional EC shard placement Add a new reusable package for EC shard distribution that: - Supports configurable EC ratios (not hard-coded 10+4) - Distributes shards proportionally based on replication policy - Provides fault tolerance analysis - Prefers moving parity shards to keep data shards spread out Key components: - ECConfig: Configurable data/parity shard counts - ReplicationConfig: Parsed XYZ replication policy - ECDistribution: Target shard counts per DC/rack/node - Rebalancer: Plans shard moves with parity-first strategy This enables seaweed-enterprise custom EC ratios and weed worker integration while maintaining a clean, testable architecture. * shell: integrate distribution package for EC rebalancing Add shell wrappers around the distribution package: - ProportionalECRebalancer: Plans moves using distribution.Rebalancer - NewProportionalECRebalancerWithConfig: Supports custom EC configs - GetDistributionSummary/GetFaultToleranceAnalysis: Helper functions The shell layer converts between EcNode types and the generic TopologyNode types used by the distribution package. * test setup * ec: improve data and parity shard distribution across racks - Add shardsByTypePerRack helper to track data vs parity shards - Rewrite doBalanceEcShardsAcrossRacks for two-pass balancing: 1. Balance data shards (0-9) evenly, max ceil(10/6)=2 per rack 2. Balance parity shards (10-13) evenly, max ceil(4/6)=1 per rack - Add balanceShardTypeAcrossRacks for generic shard type balancing - Add pickRackForShardType to select destination with room for type - Add unit tests for even data/parity distribution verification This ensures even read load during normal operation by spreading both data and parity shards across all available racks. * ec: make data/parity shard counts configurable in ecBalancer - Add dataShardCount and parityShardCount fields to ecBalancer struct - Add getDataShardCount() and getParityShardCount() methods with defaults - Replace direct constant usage with configurable methods - Fix unused variable warning for parityPerRack This allows seaweed-enterprise to use custom EC ratios while defaulting to standard 10+4 scheme. * Address PR 7812 review comments Makefile improvements: - Save PIDs for each volume server for precise termination - Use PID-based killing in stop target with pkill fallback - Use more specific pkill patterns with TEST_DIR paths Documentation: - Document jq dependency in README.md Rebalancer fix: - Fix duplicate shard count updates in applyMovesToAnalysis - All planners (DC/rack/node) update counts inline during planning - Remove duplicate updates from applyMovesToAnalysis to avoid double-counting * test/erasure_coding: use mktemp for test file template Use mktemp instead of hardcoded /tmp/testfile_template.bin path to provide better isolation for concurrent test runs. |

fix: sync EC volume files before copying to fix deleted needles not being marked when decoding (#7755)
* fix: sync EC volume files before copying to fix deleted needles not being marked when decoding (#7751) When a file is deleted from an EC volume, the deletion is written to both the .ecx and .ecj files. However, these writes were not synced to disk before the files were copied during ec.decode. This caused the copied files to miss the deletion markers, resulting in 'leaked' space where deleted files were not properly tracked after decoding. This fix: 1. Adds a Sync() method to EcVolume that flushes .ecx and .ecj files to disk without closing them 2. Calls Sync() in CopyFile before copying EC volume files to ensure all deletions are visible to the copy operation Fixes #7751 * test: add integration tests for EC volume deletion sync (issue #7751) Add comprehensive tests to verify that deleted needles are properly visible after EcVolume.Sync() is called. These tests cover: 1. TestWriteIdxFileFromEcIndex_PreservesDeletedNeedles - Verifies that WriteIdxFileFromEcIndex preserves deletion markers from .ecx files when generating .idx files 2. TestWriteIdxFileFromEcIndex_ProcessesEcjJournal - Verifies that deletions from .ecj journal file are correctly appended to the generated .idx file 3. TestEcxFileDeletionVisibleAfterSync - Verifies that MarkNeedleDeleted changes are visible after Sync() 4. TestEcxFileDeletionWithSeparateHandles - Tests that synced changes are visible across separate file handles 5. TestEcVolumeSyncEnsuresDeletionsVisible - Integration test for the full EcVolume.DeleteNeedleFromEcx + Sync() workflow that validates the fix for issue #7751 * refactor: log sync errors in EcVolume.Sync() instead of ignoring them Per code review feedback: sync errors could reintroduce the bug this PR fixes, so logging warnings helps with debugging. |

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.
