Package based Ceph deployments, while popular, are not a good choice in general. The very simple reason is that it makes upgrades more dangerous: you can unintentionally upgrade services in the wrong order due to failovers.
Or when a node crashes / reboots during an upgrade. This has happened to me.
Hmmm, that is not really nice to read that ceph is so picky that everything can go wrong with just a minor update on a single node.
Then if you really want to stick with package installs, deploy every service on a separate node. Your DC runneth over.
I am not sure if that is a good direction for development.
Hence the increasing motivations for container installations, which are by nature immune from this dynamic.
I would expect ceph to be more robust.
It's not a function of Ceph, but robustness is exactly the goal.
