Upstart

Ubuntu releases earlier than Xenial (such as Trusty) use the Upstart service management system, which is almost, but not entirely unlike systemd. Here we'll list analogous Upstart commands for each task explored above.

Showing all Upstart jobs and instances on a given system:

    # initctl list | grep ceph

Stopping and starting all Ceph daemons on a host:

    # stop ceph-all
    # start ceph-all

To stop and start all instances of a particular Ceph component on a given host:

    # stop ceph-osd-all
    # start ceph-osd-all
    
    # stop ceph-mon-all
    # start ceph-mon-all
    
    # stop ceph-mds-all
    # start ceph-mds-all

To stop and start individual instances:

    # stop ceph-osd id=11
    # start ceph-osd id=11
    
    # stop ceph-mon id=monhost-005
 # start ceph-mon id=monhost-005 ...
