Re: local node on failover server.

[Jan Klopper <janklopper@xxxxxxxxx>]

How is this any different from the normal failover?

In the normal scenario the secundary server takes over the IP and starts 
arping right?
I figured i could use two "snoop" ports on my switch to connect the load 
balancers, this would force the switch to send all traffic (like a hub) 
to both of those ports.
Since the packages would then be delivered to the server no matter what 
the Mac addres in the package is, it would work right?
Normal LVS-rd also sends back the packages to the client from a 
different Mac address so that should not give any problems.
right?
If so, i;l try to modify the scripts to do all of this.
