Use location constraint to set your preference for instance in my set-up I have location PrimaryNode-pbx_service_01 pbx_service_01 200: pbxsrv1 location SecondaryNode-pbx_service_01 pbx_service_01 10: pbxsrv3 which will make pbxsrv1 the primary node for pbx_service_01 resource group You also need to make sure your resource-stickiness is low, 0 in this case will be fine.
