You do need to use the stop script, not service stop. If you use service
stop, Upstart will restart the service. It's ok for start and restart,
because that what you want anyway, but service stop is effectively a
restart.
I wouldn't recommend doing stop ceph-all and start ceph-all after an
upgrade anyway, at least not with the latest 0.61 upgrades. Due to the
MON issues between 61.4, 61.5, and 61.6, it seemed safer to follow the
major version upgrade procedure
(http://ceph.com/docs/next/install/upgrading-ceph/). So I've been
restarting MON on all nodes, then all OSDs on all nodes, then the
remaining services.
That said, it stop ceph-all should stop all the daemons. I just
wouldn't use this upgrade procedure.
On all my cluster nodes to upgrade from 0.61.5 to 0.61.7 and then noticed
that some of my systems did not restart all the daemons. I tried:
stop ceph-all
start ceph-all
