remove directory of old osd folder

[xtou]

Hi,
it's safe to rm the ceph osd directory that aren't in use?

osd.0 osd.1 osd.2 runing on other ceph note, but I notice that folder it's there from old remove disk.

root@pve01:~# ls -la /var/lib/ceph/osd

If you don't have any OSDs with that name on the host, then ok. But why at all? They will be repopulated if the OSD ID on that node will be used again.
