[Linux-cluster] RHEL6 & IP load balancing



So I just started setting up a RHEL6 box for use in a load balanced cluster and have run across a problem. The way you set up a virtual IP on the back end realhost side is to add an interface alias to the loopback device (such as lo:0). Well the ifup-eth script in RHEL6 refuses to add aliases to the loopback interface. Additionally if you try to add the alias to the real ethX device instead it fails because the arping check it does finds that the IP is already running on the IPVS director.

So, how is one supposed to setup a realhost now?
The difference from RHEL5 is that RHEL5 doesnt check to see if youre adding an alias to the loopback device or not. Why does RHEL6 even care about that anyway? Theres nothing wrong with it...
