RE: RHAS LVS Gaps

Actually, what I am trying to do is effectively give my standby web server (REAL-B) a weight of 0, and my hot web server (REAL-A) a weight of 1, but still have REAL-B handle the web hits if REAL-A goes away.   I just tried this, and the Piranha-GUI will let me put in a weight of 0, but the ipvsadm output shows a weight of 1.

Thanks for the input

RHAS supports failover does it not? I believe that is
what you are looking for. Piranha handles the load
balancing and cluster manager is for setting up the
failover? I have not implimented either of these
features yet myself, but this is my understanding from
the docs I have read this far.
