How can I test whether rgmanager will restart any resources when I update my cluster configuration in RHEL 5 or 6?
Issue
-
I need to update my cluster.conf, but I want to check if rgmanager will restart any critical resources.
-
When updating the cluster.conf to change the dependency tree, the service stopped all the resources causing an unexpected outage
