Description Charlie Wyse 2010-05-20 11:18:38 EDT
Description of problem:
Currently you can use failover domains to decide an ordered priority of when a resource or service fails, which node to fail over to.  What the customer would like to see added to cluster is the possibility to put a weight on a service or resource.  What is desired is the ability to weigh a resource that is known to have a heavy load down with a number so when the cluster fails over lighter services, it will try to reallocate those services to other nodes with less of a weight on them.

For example:  You have a 3 node cluster with 3 services X Y Z.  X=2, Y=1, Z=1. Each node is set to run 1 service on startup.  If the node running service Z fails.  It should look at the node running service X=2, and Y=1, and decide that X+Z=3 while Y+Z=2 and move the service to the node running Y before trying to relocate the service to the node running X.

While this would be a useful feature, it is too invasive to include in Red Hat Cluster Suite 4 at this point.
