Depending on the actual Ceph version you can either use
ceph-volume lvm activate --all
on the reinstalled host, if it's not managed by cephadm yet. Or if it
is you can run this:
ceph cephadm osd activate <host>...
The latter is an example from the ceph docs [1].

Zitat von ceph@xxxxxxxxxx:
As far as i know you have just to install your os and ceph.
Your osd disks will automaticaly detected.
