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.
Best regards,
Michel

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?
Regards,
Alan
