Hi,
have you checked /var/log/ceph/cephadm.log for any hints?
ceph-volume.log may also provide some information
(/var/log/ceph/<FSID>/ceph-volume.log) what might be going on.
Zitat von Manuel Holtgrewe <zyklenfrei@xxxxxxxxx>:
Dear all,
I now attempted this and my host is back in the cluster but the `ceph
cephadm osd activate` does not work.
# ceph cephadm osd activate HOST
Created no osd(s) on host HOST; already created?
Using --verbose is not too helpful either:
bestcmds_sorted:
[{'flags': 8,
'help': 'Start OSD containers for existing OSDs',
'module': 'mgr',
'perm': 'rw',
'sig': [argdesc(<class 'ceph_argparse.CephPrefix'>, req=True,
name=prefix, n=1, numseen=0, prefix=cephadm),
argdesc(<class 'ceph_argparse.CephPrefix'>, req=True,
name=prefix, n=1, numseen=0, prefix=osd),
argdesc(<class 'ceph_argparse.CephPrefix'>, req=True,
name=prefix, n=1, numseen=0, prefix=activate),
argdesc(<class 'ceph_argparse.CephString'>, req=True, name=host,
n=N, numseen=0)]}]
Submitting command: {'prefix': 'cephadm osd activate', 'host': ['HOST'],
'target': ('mon-mgr', '')}
submit {"prefix": "cephadm osd activate", "host": ["HOST"], "target":
["mon-mgr", ""]} to mon-mgr
How can I find out what goes wrong here?
Thanks!
Manuel

That could also work as long as the OSDs are still in the CRUSH map.
Keep in mind that the last command is
ceph cephadm osd activate $HOSTNAME
