Thats the idea!
You tell the cluster to run up to 4 cloned resources on the cluster as
long as possible (high availability!). And as long as possible, it will
run these four resources. It might even run several of these resources
on one node. You have to set clone-node-max appropriately to prevent all
four resources running on one node.
