Alan, I'd say yes OS and Ceph upgrades are two very separated operations. Thus I personally advise (it's what I'm doing) not to do them at the same time. It makes easier to identify the culprit in case of problems.I generally upgrade the OS before Ceph.

Unless you have to reboot a node after OS upgrade. In this case send a node into maintenance mode (ceph orch host maintenance enter <host> --force) before rebooting.

Ok, thanks for the confirmation.
Just as a followup, our Ceph nodes are running on Debian + Docker -- currently Debian 12.4. I assume that installing any OS-level updates should not affect anything Ceph-wise, as long as there are no issues with Docker? In other words, upgrading the underlying OS and Ceph are basically two very separate(d) things?

Hello,
I just wanted to check quickly, but feel I am being a little *too* cautious...
We have a Ceph cluster (installed via cephadm) that is currently version 18.2.2. The "Upgrade" tab gives me an option to upgrade to 18.2.7 (its default selection), or I can upgrade to another version where I can choose "earlier" upgrades (from 18.2.3 to the offered 18.2.7)
Is it generally OK and safe to "jump" upgrades like this (i.e. go straight from 18.2.2 straight to 18.2.7) or would it be recommended to upgrade in order (18.2.2 -> 18.2.3 -> 18.2.4 -> etc.)?
I assume once I am on latest 18.2.7, there might be an option to upgrade to 19.2.x (not that I would necessarily want to do that straight away)?
Thanks! :-)
