Pinner wired to real retention: - NewPinner calls vol.SetV2RetentionFloor(p.MinWALRetentionFloor) - Flusher.RetentionFloorFn() / SetRetentionFloorFn() exposed - SetV2RetentionFloor chains with existing shipper retention floor - Holds actually prevent WAL reclaim (not just tracked state) Executor uses real WAL scan: - BlockVol.ScanWALEntries(fromLSN, callback) wraps wal.ScanFrom with real fd, walOffset, checkpointLSN - Executor.StreamWALEntries uses ScanWALEntries (not stub) - Reads real WAL entries, tracks highest LSN scanned CommittedLSN mapping: - Explicitly documented as interim V1 model (committed = checkpointed) - Will diverge when V2 distributed commit separates from local flush Carry-forward: - TransferSnapshot/TransferFullBase/TruncateWAL: stubs (need extent I/O) - Control intent from confirmed failover: deferred Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# F8: Multi-Client Concurrent Failover
|
|
#
|
|
# Tests: 2 iSCSI clients (different IQNs) connected to same primary.
|
|
# Both write data concurrently. Kill primary → promote replica →
|
|
# both clients reconnect to new primary → verify both datasets intact.
|
|
#
|
|
# Gap: Previously untested (session-storm is sequential, not concurrent failover)
|
|
#
|
|
# Note: Uses 2 clients (not 4) since both test nodes are available.
|
|
# client_node uses 2 separate iSCSI sessions with different initiator names.
|
|
#
|
|
# Pass criteria:
|
|
# - Both clients write successfully before failover
|
|
# - After failover, both datasets are intact on promoted replica
|
|
# - No data corruption or cross-client interference
