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...
