"In other words, upgrading the underlying OS and Ceph are basically two very separate(d) things?"
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.

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?
