Hi, you can list all clients of an active MDS like this (within the container): ceph daemon mds.cephfs.ses7-host4.qvrwta session ls or list blocked operations with ceph daemon mds.cephfs.ses7-host4.qvrwta dump_blocked_ops There are a couple of other commands that could be useful, e.g. dump_historic_ops_by_duration. Did or does your cluster report stuck requests? Please provide more details if this doesn't help you resolve the issue. Regards, Eugen Zitat von "Norman.Kern" <norman.kern@gmx.com>:
