Linux cluster stack hits Debian squeeze

The full Linux cluster stack, including Pacemaker, Heartbeat, Corosync and related packages, cleared all hurdles and migrated to the Debian testing repository this morning. This means that Pacemaker and both messaging layers it supports will be in the upcoming Debian release, codenamed squeeze.

Credit goes to the debian-ha maintainers crowd for making this possible: Martin Loschwitz, …

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:

Complete Pacemaker cluster stack now in Debian

Thanks to the efforts of the Debian HA Maintainers team, the complete Pacemaker cluster stack is now available in Debian GNU/Linux. Packages are currently included only in Debian unstable (“sid“), but we expect them to make their way into squeeze (and lenny, via relatively soon.

See the following links in the Debian package database for details:

MySQL scale-out with replication and Pacemaker

It seems that the MySQL Conference selection committee didn’t seem to like the talk (and tutorial) I submitted about integrating MySQL Replication with the Pacemaker cluster stack, enabling full MySQL scale-out in an environment you previously knew only for its synchronous-replication High Availability features. But — fear not, my fellow HA geeks! — we are instead making the talk available for free, over the web, one week ahead of the conference.

In this 45-minute presentation, we will give an overview about

  • the Pacemaker cluster stack and the Linux-HA project it evolved out of;
  • the current state of MySQL integration in Pacemaker, and of course
  • leveraging Pacemaker’s built-in clone infrastructure for MySQL Replication.

It’s pretty cool stuff that the Linux-HA …

DRBD User’s Guide update — feedback appreciated!

A new version of the DRBD User’s Guide is up at As this version has some major additions to the previous release, I’ve decided to create a release
candidate this time, before declaring this an “official reference” — everyone’s feedback is requested and highly encouraged.

What’s new is Chapter 8, “Integrating DRBD with Pacemaker clusters“. It deals with the new drbd OCF resource agent we are about to release with 8.3.2, and how to use it in Pacemaker clusters using the CRM shell. It also has setup examples for MySQL, as does the legacy chapter on Heartbeat. Please grab the 8.3.2rc2 tarball if you are …
