We are in need of some very basic software that will give us the ability to swing an ip address from one host to another during controlled maintenance or host failure. For now the IP address will be the only resource that is shared and there will never be a need for shared storage. Eventually we may want to monitor processes for health (probably just read in pid file) and it would be great if the recommended software had this ability as well but not completely necessary. The process monitoring part is just me trying to think ahead but it definitely wouldn't be needed in the near future.
Ideally, this should be light weight user land code that hopefully already comes easily with the distribution :)
Any suggestions? Thanks.
I neglected one obvious detail, this will running on 32 bit CentOS 5.1.

yum install heartbeat
Very robust, very reliable, easy to configure, easy to use :-) We use it for almost every critical server for about 3 years without any problem.

I had originally considered heartbeat but just didn't know if version 2 was overkill. It's a pretty capable package and I just didn't want to get in over my head for this project. Is version 2 still pretty simple if you want it to be?

Well, exactly as you say... if you want it to be, it can be still pretty simple :)
I don't know any software which could be simplier and still so reliable for mission critical usage.
