Ceph OSD fails to restart with "lock_fsid failed to lock /var/lib/ceph/osd/ceph-X/fsid is another ceph-osd still running" in OSD logs

Issue

• When restarting the ceph service some OSDs fail to start with the following log message in /var/log/ceph-osd.#.log:

2015-09-25 17:03:54.199295 7f1633f9c7c0  0 filestore(/var/lib/ceph/osd/ceph-104) lock_fsid failed to lock /var/lib/ceph/osd/ceph-104/fsid, is another ceph-osd still running? (11) Resource temporarily unavailable

• Starting the OSD manually using the following command works fine:

 # service ceph start osd.#
