Hi, Please check the documentation for operating the Ceph cluster: http://ceph.com/docs/master/rados/operations/operating/ Specifically, for stopping all monitors you can use: sudo stop ceph-mon-all And to restart all monitors, you can use: sudo start ceph-mon-all If you want to stop/start specifice mon, use: sudo stop/start ceph-mon id={hostname} On Fri, May 30, 2014 at 2:29 PM, Cao, Buddy <buddy.cao at intel.com<mailto:buddy.cao at intel.com>> wrote: I tried to stop monitor thru ?#service ceph -a stop mon.3?, However, after a while, the monitor is still in the cluster.
