Dear community, Some time ago, I wondered why the Ceph version didn't show up in the ceph status (ceph -s) output. Perhaps it was because a Ceph cluster could run multiple versions at once (during an upgrade for example) and this information wasn't centralized, before the 'ceph versions' command was introduced. Regardless, I think it would be a great addition to have the Ceph version displayed in the ceph status. It could look something like this below. On a cluster where all daemons are on version 18.2.7: $ ceph -s cluster: version: 18.2.7 id: f4147dec-4c5d-11f0-a310-bc24113b5ce1 health: HEALTH_OK On a cluster that is currently being upgraded from 18.2.4 to 18.2.7: $ ceph -s cluster: version: 18.2.7 (432), 18.2.4 (248) <----- Could be refined. For example (3 MONs, 3 MGRs, 426 OSDs) until all daemons are on the same version. id: f4147dec-4c5d-11f0-a310-bc24113b5ce1 health: HEALTH_WARN Let me know if you like the idea and I'll create a tracker.
