* fix(ec): VolumeEcShardsInfo walks every disk on multi-disk servers When a volume server holds EC shards for the same vid across more than one disk, each DiskLocation registers its own EcVolume entry and Store.FindEcVolume returns whichever one it hits first. The shard-info RPC iterated only that single EcVolume's Shards, so the response missed every shard mounted on a sibling disk. The worker's verifyEcShardsBeforeDelete sums the per-server responses into a union bitmap and refuses to delete the source volume when the union falls short of dataShards+parityShards. On multi-disk destinations, the union was systematically under-counted and source deletion got blocked even though all shards were physically present and mounted. Walk every DiskLocation in the handler and emit the deduplicated union of all shards. The .ecx-backed fields (file counts, volume size) still come from a single EcVolume since every disk's entry opens the same .ecx via NewEcVolume's cross-disk fallback. Tests: - TestVolumeEcShardsInfo_AggregatesAcrossDisks unit test in weed/server/. - test/volume_server/grpc/ec_verify_multi_disk_test.go integration test drives the full generate -> mount -> redistribute -> restart -> reconcile path and asserts both VolumeEcShardsInfo and VerifyShardsAcrossServers + RequireFullShardSet (the production source-deletion gate) report all 14 shards. - ec_multi_disk_lifecycle_test.go tightened: replaces the "VolumeEcShardsInfo only sees one disk's EcVolume" workaround with a full-shard-set assertion. * review: use ShardBits bitmask + cap-pre-allocation for shard dedup
Volume Server Integration Tests
This package contains integration tests for SeaweedFS volume server HTTP and gRPC APIs.
Run Tests
Run tests from repo root:
go test ./test/volume_server/... -v
If a weed binary is not found, the harness will build one automatically.
Optional environment variables
WEED_BINARY: explicit path to theweedexecutable (disables auto-build).VOLUME_SERVER_IT_KEEP_LOGS=1: keep temporary test directories and process logs.
Current scope (Phase 0)
- Shared cluster/framework utilities
- Matrix profile definitions
- Initial HTTP admin endpoint checks
- Initial gRPC state/status checks
More API coverage is tracked in /Users/chris/dev/seaweedfs2/test/volume_server/DEV_PLAN.md.
