Hi,

of course there is:

It has worked great for us. The orchestrator will ensure that keyrings and configs are copied (if set to managed), so you really just have to restore the OS. So after you reinstalled the OS, you just need to run:

ceph cephadm osd activate <host>

Thanks a lot! I have been searching for this but did not find it. Gr. Stefan
