location constraints with a negative score:

http://clusterlabs.org/doc/en-US/Pacemaker/1.1-pcs/html-single/Pacemaker_Explained/index.html#_deciding_which_nodes_a_resource_can_run_on


you can even use a single constraint with a rule based on #kind ne
cluster, so you don't need a separate constraint for each node:

http://clusterlabs.org/doc/en-US/Pacemaker/1.1-pcs/html-single/Pacemaker_Explained/index.html#_node_attribute_expressions


alternatively, you can set symmetric-cluster=false and use positive
constraints for cluster nodes only
