1) write a script that measures the load of every node. Take the 5 min average! See damping below for explanation. 2) user attrd_updater to write these values into the status section of the nodes. Something like: attrd_updater -n cpu_load -v <load> -d 15 Perhaps you need to adapt damping (-d) 3) use the score_attribute to distribute the resources. See http://www.linux-ha.org/CIB/Idioms/PingdAttrAsScore and http://www.linux-ha.org/v2/faq/pingd Make extensive use of resource_stickiness to find a good balance between moving resources and overload on one node.
