I've got a replicated /mysql with vip/ setup i've been trying to create, 
and it doesnt seem to be obeying my colocation rule much.

Situation:
I had shut down corosync on all (3) nodes and verified all associated 
services were off.
I then started it up an all 3 nodes.
When it came back up, the VIP was running on node1, while the master 
mysql service was running on node 2.

I dont get it. Why did it decide to just ignore the co_mysql rule?
