Hi, I posted a link to the docs [1], [2] just yesterday ;-) You should see the respective OSD in the output of 'cephadm ceph-volume lvm list' on that node. You should then be able to get it back to cephadm with cephadm deploy --name osd.x But I haven't tried this yet myself, so please report back if that works for you.

Hello,
I have by mistake re-installed the OS of an OSD node of my Octopus cluster (managed by cephadm). Luckily the OSD data is on a separate disk and did not get affected by the re-install.
Now I have the following state:
health: HEALTH_WARN 1 stray daemon(s) not managed by cephadm 1 osds down 1 host (1 osds) down
To fix that I tried to run:
# ceph orch daemon add osd ceph1f:/dev/sda Created no osd(s) on host ceph1f; already created?
That did not work, so I tried:
# ceph cephadm osd activate ceph1f no valid command found; 10 closest matches: ... Error EINVAL: invalid command
Did not work either. So I wanted to ask how can I "adopt" back an OSD disk to my cluster?
Thanks for your help.
