mds: session reclaim could miss blocklisting an old session#66180
Conversation
Credit to ymo zhang[0] for the RCA and the fix. This is due to a race between a client session close (which is retired by the MDS) and a session open sent by the client due to MDSMap update for the MDS state change. This results in the old session still holding the client uuid (in client metadata).
