The best way is to set all your resources to unmanaged mode, stop heartbeat, change configuration, start heartbeat, and put resources back to the managed mode. Look for the is_managed attribute at linux-ha.org. This is only if you're using the v2/CIB style configuration. With v1, I'm not sure if that's possible at all.
