The resources does not go back to Nomen anymore when it's heartbeat is started again (resources stays with Rubric). However, the resources still gets bounced once Nomen joins the cluster. Is there any way to keep the resources from bouncing when Nomen rejoins the cluster?
Please share your current configuration.

If I manually turn off any of these resources, I would like the group resource, Directory_Server, to failover to the other node. Is there a configuration that will do this? Currently, if one of three resources goes down it stays down and the rest continues running. All three resources will need to be up and running for our applications to work properly.
Sounds like you're not doing any resource monitoring. Read up on that
and configure it. The ScoreCalculation page might be handy to understand
how things work: http://www.linux-ha.org/ScoreCalculation
