Hi,

please try :

[mon.odcf-pve0X]

 host = hostname
 mon addr = 192.168.255.x:6789

seperate entry for each

yes /etc/ceph/ceph.conf is identical on all three hosts and there is a
mon_host line with the correct IPs.  Interestingly there is a special
section for odcf-pve02:

-----------
[mon.odcf-pve02]
     public_addr = 192.168.255.2
-----------

This is the same IP as in the mon_host line.  However there is no
equivalent section for the other two nodes.

I will check that (tomorrow :-)


using the monitor's admin socket on either of the three nodes I can
query the monitors of 01 and 03 (the good ones) but not of 02 (the
problematic one):

root@odcf-pve01:~# ceph tell mon.odcf-pve02 mon_status
Error ENOENT: problem getting command descriptions from
mon.odcf-pve02
root@odcf-pve01:~#

The monitor daemon is running on all three and the ports are open.

Any other ideas?

You could check the permissions on the socket:

ss -xln | grep ceph-mon
SOCK=$(ss -xln | awk '/ceph-mon/ {print $5}')
ls -la ${SOCK}

On my host, this shows

srwxr-xr-x 1 ceph ceph 0 Dec 20 23:47
/var/run/ceph/ceph-mon.px-alpha-cluster.asok

same here
