Hello, I had to rebuld a data directory of one of my mons, but now I can't get the new mon to join the cluster. What I did was based on this documentation: https://docs.ceph.com/en/latest/rados/operations/add-or-rm-mons/ ceph mon remove mon1 ssh root@mon1 mkdir /var/lib/ceph/mon/tmp mkdir /var/lib/ceph/mon/ceph-mon1 ceph auth get mon. -o /var/lib/ceph/mon/tmp/keyring ceph mon getmap -o /var/lib/ceph/mon/tmp/monmap ceph-mon -i mon1 --mkfs --monmap /var/lib/ceph/mon/tmp/monmap --keyring /var/lib/ceph/mon/tmp/keyring chown -R ceph:ceph /var/lib/ceph/mon/ceph-mon1 systemctl start ceph-mon@mon1.service Now "ceph -s" reports only two mons, and in /var/log/ceph/ceph-mon.mon1.log there following lines are being added every few seconds: 2022-09-08T16:08:50.578+0200 7f5f322d9700 1 mon.mon1@0(probing) e21 handle_auth_request failed to assign global_id 2022-09-08T16:08:51.630+0200 7f5f322d9700 1 mon.mon1@0(probing) e21 handle_auth_request failed to assign global_id This is with Octopus, but tried also upgrade this single mon to Pacific, CentOS 8. What can be wrong, why the new mon does not join the cluster, as described in the above documentation?
