Hi all!
The mds of our ceph cluster produces a health_err state.
It is a nautilus 14.2.2 on debian buster installed from the repo made by
croit.io with osds on bluestore.
The symptom:
# ceph -s

health: HEALTH_ERR
1 MDSs report damaged metadata

mon: 3 daemons, quorum mon1,mon2,mon3 (age 2d)
mgr: mon3(active, since 2d), standbys: mon2, mon1
mds: cephfs_1:1 {0=mds3=up:active} 2 up:standby
osd: 30 osds: 30 up (since 17h), 29 in (since 19h)

}

I tried this without much luck:
# ceph daemon mds.0 "~mds0/stray7/100005161f7/dovecot.index.backup" recursive
repair
admin_socket: exception getting command descriptions: [Errno 2] No such file or
directory
Is there a way out of this error?
Thanks and best regards,
Lars
