/var/lib/ceph/mon/tmp/keyring
: chown -R ceph:ceph /var/lib/ceph/mon/ceph-mon1
: systemctl start ceph-mon@mon1.service
I tried to reboot the mon1 node, and once again did the above.
Now I don't see the "failed to assign global_id" log messages, but instead
this one:
2022-09-08T16:38:10.826+0200 7f72bb1a9700 0 mon.mon1 does not exist in monmap,
will attempt to join an existing cluster
2022-09-08T16:38:10.827+0200 7f72bb1a9700 0 using public_addr v2:X.Y.1.1:0/0

123...my-fsid...def
So now it apparently tries to join a new cluster.
I also see traffic coming from other two mons to port 3300 of this host,
so they try to communicate.
But in "ceph -s" there remain only two mons.
The fsid and the public IP address appear to be correct.
How can I debug this further? Thanks,

We all agree on the necessity of compromise. We just can't agree on
when it's necessary to compromise. --Larry Wall
