modes
Must ensure all writes prior to failover are flushed
before processing replay of reads or writes
Replay, duplicate resolved via sequence numbers
Established byte range locks
Server preserves, client does not replay
Sticky timestamps
Office interop
SMB2 FIDs describing open handles
Only the persistent portion of SMB2 FID is needed
Enumeration of dir & EAs
Client restarts enumeration (Win32 API compliant)
Close
Client replays

Renegotiated on open re-establishment.

Operation
replay
Comments
SMB2 Redirector
Simple Replay of
operation
(requires server state
to ensure correct
operation)
CREATE (file or directory)
Using prior Create GUID, issue “re-open”.
Read or Write I/Os
Replay (after Create is reconnected).
Rename/set DELETE_DISPOSITION
SMB2 FID or GUID used for open data handles,
lease handles, opened for delete/rename handles.
In progress byte range lock requests
Replay - duplicates resolved via sequence numbers
FSCTLs
Replay after re-open
Close
Replay (re-open, then close), but re-open fails, is
okay
Directory Lease state
Renegotiation can cause directory cache flush.
File Lease state
Write+Handle leases preserved, all else could be
renegotiated
Cached file data & metadata
Write-Back data cache is preserved. May cause flush
of metadata and/or read caches.
Granted byte range locks
No replay – server preserves.
Enumeration State (dir and EAs)
Start enumeration over, skip entries already
returned.
Change notification queue/block
Complete to app with error code to force reenumeration/requeue.
Attempt to replay,
potentially
renegotiate
