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

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

Any other ideas?

Cheers, Frank
