Take a look at the config here, it does what you need, you
probably have to adapt to your specific setup.<br>

It's a three-node CRM cluster where node C acts as a failover for nodes
A and B, but nodes A and B do not fail over to each other. However, in a
three-node CRM cluster, all resources are allowed to run on all nodes by
default. For example, even though resource R1 only physically exists on
nodes A and C, if node A fails Pacemaker might try to start it on node B
if we don't put in some kind of constraints. You follow?
