The one for RHEL4.

Yes, I've seen it, but that's not what I want.

That would be an option, but I have a two node cluster, so failover domains do not give me this.

I'm thinkig of simply adding appropriate checks to init scripts of these two services, so if one is already up, the other would fail on start and the cluster is going to try starting it on the other node (hopefully).
