[Pacemaker] VIP on Active/Active cluster

[David Coulson]

Cloning IPAddr2 resources utilizes the iptables CLUSTERIP rule. Probably a good idea to start looking at it w/ tcpdump and seeing if either box gets the icmp echo-request packet (from a ping) and determining if it just doesn't respond properly, doesn't get it at all, or something else.

I'd say it's more of a iptables/networking issue than it is a pacemaker problem now. That said, you didn't detail why you wanted a shared VIP in the first place, or what the application is, so it's perhaps going to cause more problems than it's worth (e.g. if your app is running, but is broke on one box, the VIP will still route users to it).
