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 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 -> [v2:X.Y.1.1:3300/0,v1:X.Y.1.1:6789/0] 2022-09-08T16:38:10.828+0200 7f72bb1a9700 0 starting mon.mon1 rank -1 at public addrs [v2:X.Y.1.1:3300/0,v1:X.Y.1.1:6789/0] at bind addrs [v2:X.Y.1.1:3300/0,v1:X.Y.1.1:6789/0] mon_data /var/lib/ceph/mon/ceph-mon1 fsid 123...my-fsid...def 2022-09-08T16:38:10.834+0200 7f72bb1a9700 1 mon.mon1@-1(???) e0 preinit fsid 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?
