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

Hi,

I don't kown which client held it.
