Two bugs prevented reliable volume balancing when a Rust volume server is the copy target: 1. find_last_append_at_ns returned None for delete tombstones (Size==0 in dat header), falling back to file mtime truncated to seconds. This caused the tail step to re-send needles from the last sub-second window. Fix: change `needle_size <= 0` to `< 0` since Size==0 delete needles still have a valid timestamp in their tail. 2. VolumeTailReceiver called read_body_v2 on delete needles, which have no DataSize/Data/flags — only checksum+timestamp+padding after the header. Fix: skip read_body_v2 when size == 0, reject negative sizes. Also: - Unify gRPC server bind: use TcpListener::bind before spawn for both TLS and non-TLS paths, propagating bind errors at startup. - Add mixed Go+Rust cluster test harness and integration tests covering VolumeCopy in both directions, copy with deletes, and full balance move with tail tombstone propagation and source deletion. - Make FindOrBuildRustBinary configurable for default vs no-default features (4-byte vs 5-byte offsets).
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
