Hi,
we had bad blocks on one OSD and around the same time a network switch
outage, which seems to have caused some corruption on the mon service.
> # ceph -s

14097 slow ops, oldest one blocked for 56417 sec, mon.server6 has slow ops
The mon ops log looks like:

It seems, that the mds transactions don't finish, while waiting for
mdsmap. In the mds server, there are no ops in flight, nor any errors in
the log file.
What is the proper way to repair this ?
kind regards
poelzi
