Red Hat Bugzilla – Bug 594409
[RFE] Add weights to resources.
Last modified: 2010-10-06 19:34:52 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.
