[Pacemaker] How are Scores computed regarding roles?

[Marcos Tiago]

Guys,

I am having trouble configuring a collocation in crm (corosync), but I am not sure if what I want is possible. This is the scenario:

Let's say it's a 2 node cluster, with one resource in each. RES1 is with location inf in Node1, and RES2 is with location inf in Node2. Both resources are in Started role.

I have a third resource (IP address) that has: colocation 20 with RES1 and colocation 10 with RES2, so that if RES1 fails, it moves to node2.

When RES1 is restarted after a failure, the IP resource moves to Node 1, as expected.

But the IP is moving to Node 1 *before* RES1 is in Started state, which is not good for my situation because RES1 is not ready to receive requests yet.

I would like the IP to move back to Node 1 only when RES1 is in Started role.

In other words, I would like the score associated with RES1 to be computed only when RES1 is Started.

Is this even possible? If it is, how? If it's not, then how could I achieve such behavior?

Thanks!
