I'm using Debian (sarge, since stable is just too out of date, and I've never had a problem with sarge (touch wood)).  I'm running a 2.6.9 kernel, but I also had it running off 2.6.8.1

I grab the source from kernel.org, and then compile it up myself - I pick a few options that other people may not (mainly relating to the hardware I've got, which isn't exactly standard) but other than that it's pretty "simple". I've used the make-kpkg stuff from debian to allow me to better manage the created kernels, but that's the only thing "non-vanilla" about it.

2 at the moment - there's a couple of posts from me in the last few days about attempting to put a sparc node in as a 3rd node, but that's not really working out properly at the moment.  If that doesn't work, I've got another x86 motherboard lying around that I'll use to stick a normal 3rd node in the cluster - I like the idea of 3, since I've only really used 2 node clusters (sun, hp, aix) before.

The 2 node config file is pretty much nicked from that usage.txt, since that's what I used to create it, although I don't have any fencing devices:
