Was there a MON running previously on that host? Do you see the daemon when running 'cephadm ls'? If so, remove it with 'cephadm rm-daemon --name mon.s-26-9-17'

Zitat von Fyodor Ustinov <u...@ufm.su>:

Hi!

After upgrading to version 16.2.6, my cluster is in this state:

root@s-26-9-19-mon-m1:~# ceph -s
  cluster:
    id:     1ef45b26-dbac-11eb-a357-616c355f48cb
    health: HEALTH_WARN
            failed to probe daemons or devices

In logs:

9/17/21 1:30:40 PM[ERR]cephadm exited with an error code: 1, stderr:Inferring config /var/lib/ceph/1ef45b26-dbac-11eb-a357-616c355f48cb/mon.s-26-9-17/config ERROR: [Errno 2] No such file or directory: '/var/lib/ceph/1ef45b26-dbac-11eb-a357-616c355f48cb/mon.s-26-9-17/config' Traceback (most recent call last): File "/usr/share/ceph/mgr/cephadm/serve.py", line 1366, in _remote_connection yield (conn, connr) File "/usr/share/ceph/mgr/cephadm/serve.py", line 1263, in _run_cephadm code, '\n'.join(err))) orchestrator._interface.OrchestratorError: cephadm exited with an error code: 1, stderr:Inferring config /var/lib/ceph/1ef45b26-dbac-11eb-a357-616c355f48cb/mon.s-26-9-17/config ERROR: [Errno 2] No such file or directory: '/var/lib/ceph/1ef45b26-dbac-11eb-a357-616c355f48cb/mon.s-26-9-17/config'

But:
1. There is no mon service on the s-26-9-17 node.
2. All services in the cluster work normally.

What could be causing this and how can it be fixed? Thanks in advance for your help!


WBR,
    Fyodor.
