I'm playing around with the nfscookbook on a test cluster. I'm finding
some really odd behavior. I can't seem to get the services to 'stick' the
cluster node with the lowest priority.
When a cluster node starts a services, it seems to re-locate other
services for no apparent reasons. Have I've done something wrong?
Thanks,
Dennis
