Hi All,
I'm getting this error while setting up a ceph cluster. I'm relatively new to
ceph, so there is no telling what kind of mistakes I've been making. I'm using
cephadm, ceph v16 and I apparently have a stray daemon. But it also doesn't
seem to exist and I can't get ceph to forget about it.
$ ceph health detail
[WRN] CEPHADM_STRAY_DAEMON: 1 stray daemon(s) not managed by cephadm
stray daemon mon.cmon01 on host cmgmt01 not managed by cephadm
mon.cmon01 also shows up in dashboard->hosts as running on cmgmt01. It does not
show up in the monitors section though.
But, there isn't a monitor daemon running on that machine at all (no podman
container, not in process list, not listening on a port).
On that host in cephadm shell,
# ceph orch daemon rm mon.cmon01 --force
Error EINVAL: Unable to find daemon(s) ['mon.cmon01']
I don't currently have any real data on the cluster, so I've also tried
deleting the existing pools (except device_health_metrics) in case ceph was
connecting that monitor to one of the pools.
I'm not sure what to try next in order to get ceph to forget about that daemon.
