Ceph - Unable to stop or start MON or OSD service with 'systemctl'

Solution Verified - Updated -


  • 'systemctl stop/start ceph' does not stop/start the Ceph MON or OSD services.
  • 'systemctl stop/start [daemon-type.[instance]' does not stop/start the MON or OSD service.

  • Issuing 'systemctl stop ceph' does not kill the Ceph processes on the node:

# ceph@cephmon1:TESTING:~> sudo systemctl stop ceph
# ceph@cephmon1:TESTING:~> ps ax | grep ceph
