If you want auto-failback to a specific node you have to set the preference of a resource to a node.
e.g.
crm configure location location-resource1 resource1 100: node1

If the difference between this location preference and the node that it is running on is higher than the cluster suite stickiness it will migrate the resource.
The stickiness off the cluster suite is set as follows:
crm_attribute --type rsc_defaults --attr-name resource-stickiness --attr-value 50
