You are right, I used the FSID of the OSD and not of the cluster in the deploy command. So now I tried again with the cluster ID as FSID but still it does not work as you can see below:
ubuntu@ceph1f:~$ sudo cephadm deploy --name osd.2 --fsid 8d47792c-987d-11eb-9bb6-a5302e00e1fa
Deploy daemon osd.2 ...
Traceback (most recent call last):
File "/usr/local/sbin/cephadm", line 6223, in <module>
r = args.func()
File "/usr/local/sbin/cephadm", line 1440, in _default_image
return func()
File "/usr/local/sbin/cephadm", line 3457, in command_deploy
deploy_daemon(args.fsid, daemon_type, daemon_id, c, uid, gid,
File "/usr/local/sbin/cephadm", line 2193, in deploy_daemon
deploy_daemon_units(fsid, uid, gid, daemon_type, daemon_id, c,
File "/usr/local/sbin/cephadm", line 2255, in deploy_daemon_units
assert osd_fsid
AssertionError
In case that's of any help here is the output of the "cephadm ceph-volume lvm list" command:
