mds: force replay sessionmap version #49970
Conversation

@lxbsz I would also like to suggest this commit message as i feel the current one needs some corrections:
|
When expiring the MDLog Segments it will persist the sessionmap, but in case the number of Segments doesn't reach up to the max segment threshold then the expiry may not happen. So if there is a MDS failover then the sessionmap won't be persistent and cannot be replayed by the standby MDS when it is starting. We should just force replay the sessionmap version just the way inotable does. Fixes: https://tracker.ceph.com/issues/58489 Signed-off-by: Xiubo Li <xiubli@redhat.com>

@lxbsz There were two issues, one is the replay stuck for really long time and other is the crash. Does this fix both the issues ?
@kotreshhr They should be the same issue IMO. |
