This error occurs because of orphaned directories under /var/lib/ceph/osd/ . These sub-directories should be empty and only serve as mountpoints. Because the sub-directories exist, Ceph will assume an OSD exists and try to mount them. Consequently, it will fail because they cannot be mounted.) F7 P$ z% F, f  N! i/ q
