cluster comes up from stopped state.

6. Run Exclusive checkbox — This sets a policy wherein the service only runs on nodes that

have no other services running on them. For example, for a very busy web server that is

alone with no other services competing for his resources — that is, Run Exclusive checked.

On the other hand, services that consume few resources (like NFS and Samba), can run

together on the same node without little concern over contention for resources. For those
