Ubuntu 10.04 with full cluster stack support

Just in case you haven’t noticed, Ubuntu 10.04 “Lucid Lynx” has arrived. I upgraded my personal box over the weekend, and am happy to report that things went pretty flawlessly for me. So I’m now a happy lucid user.

What’s more important for the ever-growing cluster community is the fact that this LTS release comes with built-in support for the Pacemaker cluster stack — and indeed, it’s the first commercially-supported distribution that comes with support for both the Heartbeat and the Corosync cluster messaging layer. And it’s easy, too!

Here’s how I install the Pacemaker stack with Heartbeat (which I prefer) on an Ubuntu box:

aptitude install heartbeat pacemaker

And if you choose to go with Corosync, here’s how.

aptitude install corosync pacemaker

… and you’re good to go!
