Make sure your resource agent returns exit codes expected by Pacemaker:
http://clusterlabs.org/doc/en-US/Pacemaker/1.1-pcs/html-single/Pacemaker_Explained/index.html#s-ocf-return-codes
In particular, if a monitor command returns 0 (OCF_SUCCESS), it means
the service is running.
When any node reboots, Pacemaker will "probe" the existing state of all
resources on it, by running a one-time monitor command. If the service
is not running, the command should return 7 (OCF_NOT_RUNNING).
So, I'm guessing that either the resource agent is wrongly returning 0
for monitor when the service is not actually running, or the node is
wrongly starting the service at boot, outside cluster control.
