You need three nodes / entitlements.

You can use Red Hat Cluster Manager for failover, too. Having a GFS entitlement includes Cluster Suite, IIRC.

This will all be released sometime soon as a layered product for RHEL4. -- Lon -- Linux-cluster@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/linux-cluster
