[Pacemaker] Monitor process, migrate only ip resources

Yes, you are correct. I manually stopped kamailio and messed with its config script so it would not start again. 
The resources were migrated to the secondary node =). Awesome piece of software!

So in theory I now have a broken primary server which I should fix. Once fixed, how will the resources be migrated back to the primary again? Does heartbeat take care of this or do I need to instruct heartbeat to do stuff?

Pacemaker always tries to restart a failed resources on it's original hosting node.
Only if it fails to do so it will migrate the resource(s) to another node.

I guess the question is: is failcount incremented when a failed resource
*is* restarted on the same node and no transition occurs .
