fix: volume balance detection returns multiple tasks per run (#8559)
* fix: volume balance detection now returns multiple tasks per run (#8551) Previously, detectForDiskType() returned at most 1 balance task per disk type, making the MaxJobsPerDetection setting ineffective. The detection loop now iterates within each disk type, planning multiple moves until the imbalance drops below threshold or maxResults is reached. Effective volume counts are adjusted after each planned move so the algorithm correctly re-evaluates which server is overloaded. * fix: factor pending tasks into destination scoring and use UnixNano for task IDs - Use UnixNano instead of Unix for task IDs to avoid collisions when multiple tasks are created within the same second - Adjust calculateBalanceScore to include LoadCount (pending + assigned tasks) in the utilization estimate, so the destination picker avoids stacking multiple planned moves onto the same target disk * test: add comprehensive balance detection tests for complex scenarios Cover multi-server convergence, max-server shifting, destination spreading, pre-existing pending task skipping, no-duplicate-volume invariant, and parameterized convergence verification across different cluster shapes and thresholds. * fix: address PR review findings in balance detection - hasMore flag: compute from len(results) >= maxResults so the scheduler knows more pages may exist, matching vacuum/EC handler pattern - Exhausted server fallthrough: when no eligible volumes remain on the current maxServer (all have pending tasks) or destination planning fails, mark the server as exhausted and continue to the next overloaded server instead of stopping the entire detection loop - Return canonical destination server ID directly from createBalanceTask instead of resolving via findServerIDByAddress, eliminating the fragile address→ID lookup for adjustment tracking - Fix bestScore sentinel: use math.Inf(-1) instead of -1.0 so disks with negative scores (high pending load, same rack/DC) are still selected as the best available destination - Add TestDetection_ExhaustedServerFallsThrough covering the scenario where the top server's volumes are all blocked by pre-existing tasks * test: fix computeEffectiveCounts and add len guard in no-duplicate test - computeEffectiveCounts now takes a servers slice to seed counts for all known servers (including empty ones) and uses an address→ID map from the topology spec instead of scanning metrics, so destination servers with zero initial volumes are tracked correctly - TestDetection_NoDuplicateVolumesAcrossIterations now asserts len > 1 before checking duplicates, so the test actually fails if Detection regresses to returning a single task * fix: remove redundant HasAnyTask check in createBalanceTask The HasAnyTask check in createBalanceTask duplicated the same check already performed in detectForDiskType's volume selection loop. Since detection runs single-threaded (MaxDetectionConcurrency: 1), no race can occur between the two points. * fix: consistent hasMore pattern and remove double-counted LoadCount in scoring - Adopt vacuum_handler's hasMore pattern: over-fetch by 1, check len > maxResults, and truncate — consistent truncation semantics - Remove direct LoadCount penalty in calculateBalanceScore since LoadCount is already factored into effectiveVolumeCount for utilization scoring; bump utilization weight from 40 to 50 to compensate for the removed 10-point load penalty * fix: handle zero maxResults as no-cap, emit trace after trim, seed empty servers - When MaxResults is 0 (omitted), treat as no explicit cap instead of defaulting to 1; only apply the +1 over-fetch probe when caller supplies a positive limit - Move decision trace emission after hasMore/trim so the trace accurately reflects the returned proposals - Seed serverVolumeCounts from ActiveTopology so servers that have a matching disk type but zero volumes are included in the imbalance calculation and MinServerCount check * fix: nil-guard clusterInfo, uncap legacy DetectionFunc, deterministic disk type order - Add early nil guard for clusterInfo in Detection to prevent panics in downstream helpers (detectForDiskType, createBalanceTask) - Change register.go DetectionFunc wrapper from maxResults=1 to 0 (no cap) so the legacy code path returns all detected tasks - Sort disk type keys before iteration so results are deterministic when maxResults spans multiple disk types (HDD/SSD) * fix: don't over-fetch in stateful detection to avoid orphaned pending tasks Detection registers planned moves in ActiveTopology via AddPendingTask, so requesting maxResults+1 would create an extra pending task that gets discarded during trim. Use len(results) >= maxResults as the hasMore signal instead, which is correct since Detection already caps internally. * fix: return explicit truncated flag from Detection instead of approximating Detection now returns (results, truncated, error) where truncated is true only when the loop stopped because it hit maxResults, not when it ran out of work naturally. This eliminates false hasMore signals when detection happens to produce exactly maxResults results by resolving the imbalance. * cleanup: simplify detection logic and remove redundancies - Remove redundant clusterInfo nil check in detectForDiskType since Detection already guards against nil clusterInfo - Remove adjustments loop for destination servers not in serverVolumeCounts — topology seeding ensures all servers with matching disk type are already present - Merge two-loop min/max calculation into a single loop: min across all servers, max only among non-exhausted servers - Replace magic number 100 with len(metrics) for minC initialization in convergence test * fix: accurate truncation flag, deterministic server order, indexed volume lookup - Track balanced flag to distinguish "hit maxResults cap" from "cluster balanced at exactly maxResults" — truncated is only true when there's genuinely more work to do - Sort servers for deterministic iteration and tie-breaking when multiple servers have equal volume counts - Pre-index volumes by server with per-server cursors to avoid O(maxResults * volumes) rescanning on each iteration - Add truncation flag assertions to RespectsMaxResults test: true when capped, false when detection finishes naturally * fix: seed trace server counts from ActiveTopology to match detection logic The decision trace was building serverVolumeCounts only from metrics, missing zero-volume servers seeded from ActiveTopology by Detection. This could cause the trace to report wrong server counts, incorrect imbalance ratios, or spurious "too few servers" messages. Pass activeTopology into the trace function and seed server counts the same way Detection does. * fix: don't exhaust server on per-volume planning failure, sort volumes by ID - When createBalanceTask returns nil, continue to the next volume on the same server instead of marking the entire server as exhausted. The failure may be volume-specific (not found in topology, pending task registration failed) and other volumes on the server may still be viable candidates. - Sort each server's volume slice by VolumeID after pre-indexing so volume selection is fully deterministic regardless of input order. * fix: use require instead of assert to prevent nil dereference panic in CORS test The test used assert.NoError (non-fatal) for GetBucketCors, then immediately accessed getResp.CORSRules. When the API returns an error, getResp is nil causing a panic. Switch to require.NoError/NotNil/Len so the test stops before dereferencing a nil response. * fix: deterministic disk tie-breaking and stronger pre-existing task test - Sort available disks by NodeID then DiskID before scoring so destination selection is deterministic when two disks score equally - Add task count bounds assertion to SkipsPreExistingPendingTasks test: with 15 of 20 volumes already having pending tasks, at most 5 new tasks should be created and at least 1 (imbalance still exists) * fix: seed adjustments from existing pending/assigned tasks to prevent over-scheduling Detection now calls ActiveTopology.GetTaskServerAdjustments() to initialize the adjustments map with source/destination deltas from existing pending and assigned balance tasks. This ensures effectiveCounts reflects in-flight moves, preventing the algorithm from planning additional moves in the same direction when prior moves already address the imbalance. Added GetTaskServerAdjustments(taskType) to ActiveTopology which iterates pending and assigned tasks, decrementing source servers and incrementing destination servers for the given task type. |

fix: resolve ServerAddress to NodeId in maintenance task sync (#8508)
* fix: maintenance task topology lookup, retry, and stale task cleanup 1. Strip gRPC port from ServerAddress in SyncTask using ToHttpAddress() so task targets match topology disk keys (NodeId format). 2. Skip capacity check when topology has no disks yet (startup race where tasks are loaded from persistence before first topology update). 3. Don't retry permanent errors like "volume not found" - these will never succeed on retry. 4. Cancel all pending tasks for each task type before re-detection, ensuring stale proposals from previous cycles are cleaned up. This prevents stale tasks from blocking new detection and from repeatedly failing.

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 |

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> |
