Hi,
Is there any other way excpet rebooting the server when the client hangs?
If the server is in production environment, I can't restart it everytime.
One method that worked for me today:
- failover to other mds (during failover the client disconnect should be
denied, e.g. 'mds.ceph-storage-01 [INF] denied reconnect attempt (mds is
up:reconnect) from client.19660826 192.168.2.92:0/2522971681 (session is
closed)')
- failover to first mds again (this time, the client should not try to
connect. mds_sessions in the debug directory should not list a session)
- accessing the mountpoint triggered a reconned to the now active mds
