Hi,

This morning one of my three monitor hosts got booted from the Nautilus 14.2.4 cluster and it won’t regain. There haven’t been any changes, or events at this site at all. The conf file is the [unchanged] and the same as the other two monitors. The host is also running the MDS and MGR apps without any issue. The ceph-mon log shows this repeating:

2020-01-08 13:33:29.403 7fec1a736700 1 mon.cephmon02@1(probing) e7 handle_auth_request failed to assign global_id
2020-01-08 13:33:29.433 7fec1a736700 1 mon.cephmon02@1(probing) e7 handle_auth_request failed to assign global_id
2020-01-08 13:33:29.541 7fec1a736700 1 mon.cephmon02@1(probing) e7 handle_auth_request failed to assign global_id
...

Try gathering a log with debug_mon 20. That should provide more detail about why  AuthMonitor::_assign_global_id() didn't return an ID.


There is nothing in the logs of the two remaining/healthy monitors. What is my best practice to get this host back in the cluster?
