Description
I many times break actions (debug mysql replication script, just multiple dump redirections) directly to directory, mounted via kernel on one of 3 node to 2 other nodes (to avoid kernel-to-userspace problems on same machine). After one of break it directory is "stuck" (others are good). Multiple time restarting mds, and even once upgrade whole ceph, now all clients connected to all 3 mds list... Directory stuck. IMHO there are another locking bug. Mds debug 10 attached for actual MDS.
