[ClusterLabs] Is corosync supposed to be restarted if it fies?

[Andrei Borzenkov]

In one of guides suggested procedure to simulate split brain was to kill
corosync process. It actually worked on one cluster, but on another
corosync process was restarted after being killed without cluster
noticing anything. Except after several attempts pacemaker died with
stopping resources ... :)

This is SLES12 SP2; I do not see any Restart in service definition so it
probably not systemd.
