How to ceph-volume on remote hosts?
Hello, I am new to CEPH and on a few test servers attempting to setup and learn a test ceph system. I started off the install with the "Cephadm" option and it uses podman containers. Followed steps here: https://docs.ceph.com/docs/master/cephadm/install/ I ran the bootstrap, added remote hosts, added monitors and everything is looking good. Now I would like to add OSDs... On the bootstrapped server i did a : ceph-volume lvm prepare --data /dev/sda6 and then the "activate" and "ceph orch daemon add osd (etc)" to add it and it works... But now I am ready to add OSDs on the remote nodes. I am not able to find documentation or examples on how to do : ceph-volume lvm prepare & activate steps on the remote hosts. How do we prepare & activate the remote hosts disks? Thank you very much for your input, Cheers Steve

ceph orch apply osd as described in https://docs.ceph.com/docs/master/cephadm/install/#deploy-osds should do the trick. In case it doesn't, what's the output of ceph orch device ls ?
Thank you very much for your input,

Hello, If you do it, like Sebastian told you, you would automatically deploy osd's. For a beginner I would recommend to do it semi-automated, so you know a bit more what's going on. So first do the "ceph orch device ls" which should print every disk, in all nodes. Then I recommend to zap devices you want to use first, even if it says you can use them: ceph orch device zap {node} /dev/sd? --force And then you can add devices one by one: ceph orch daemon add osd {node}:/dev/sd? Just to top it off. Regards, Simon -----Ursprüngliche Nachricht----- Von: Sebastian Wagner [mailto:swagner@suse.com] Gesendet: Mittwoch, 24.
