Description

This morning I tried adding a mon node to my home Ceph cluster (mid-upgrade from 15.2.13 to 16.2.4) with the following command:

ceph orch daemon add mon ether

This seemed to work at first, but then it decided to remove it fairly quickly which broke the cluster because the mon. keyring was also removed:

Digging in to this it seems like this line might need to check for 'mon.' and not 'mon':
