Redhat 5 Cluster suite

[David Hardy]

You go, Kenny.  I know it can be done; it's just the mess one has to go
through to get it all working.  If RH support is being paid for, then one of
their RHCEs should have had the experience and training by now to help out.
I was just a RHCT and finally deprived of the opportunity to make it happen
with RHEL 4, but no use crying over spilt milk.

Please let us know the particulars when you and the organization get it
going;  I'd love to be able to try this again somewhere.
