Agree 100%. Like I said, the right solution depends on your situation. If you're using the server doing ceph storage only for file serving, then protecting the OS installation isn't very important. Heck, you could just run the OS off of a USB stick. If you're running nodes that do a combination of application and storage, then obviously you need to worry about both, which probably means not relying on ceph as your sole source of protection. That applies to a lot of "kitchen sink" setups where hosts don't have a single role. -- Rich
