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]. Regards, Eugen [1] https://docs.ceph.com/en/latest/cephadm/osd/#activate-existing-osds Zitat von ceph@elchaka.de:
As far as i know you have just to install your os and ceph.
Your osd disks will automaticaly detected.
