While Yves presents a valid approach for managing NDB with Pacemaker and the anything Linux-HA resource agent (a generic wrapper for any daemon based application), the XML configuration shown is likely to have people running away screaming. This is how we had to do things back in the Heartbeat 2 days, which meant that as a cluster admin you would permanently run around with a loaded cocked shotgun with the muzzle pressed firmly against your foot.

Those days are long gone. Please don’t do this anymore. You also no longer need to use the low-level tools such as cibadmin or crm_attribute.

We have the crm shell …

Andrew just published an update to his Clusters from Scratch documentation that contains a step-by-step guide for initially setting up DRBD based cluster resources on Fedora 13.

Yes, that’s the Fedora release with Linux 2.6.33, so no more installing DRBD kernel modules.

…

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, …

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 …

MySQL replication support for the Pacemaker cluster manager (the stuff that we explained in this webinar) has made it into the Linux-HA resource agents default branch. If you are interested in testing — and you should! — please read the extended announcement. Feedback is extremely welcome on the linux-ha-dev mailing list.

We are expecting to release this as part of resource-agents 1.0.4, in late May/early June. …

We’re sticking with databases for our current round of webinars. Up next is an overview of Oracle high availability clustering on Linux.

In this 45-minute presentation, we will show you how to quickly and easily configure an Oracle database with an associated TNS Listener in a failover configuration, how to monitor both your database and your listener for failures, and how to have Pacemaker automatically intervene and recover from outages.

Brought to you in association with our friends over at Novell, we’ll showcase Oracle in combination with SUSE Linux Enterprise High Availability Extension.

This webinar is scheduled for April 28, 2010 at 1500 UTC.

As all of our webinars, this one requires registration — but we’ve made things easier for you. …

I just got word that a talk about iSCSI High Availability with Pacemaker and DRBD, which I submitted for LinuxTag 2010, has been accepted by the selection committee.

The presentation is entitled Storage Done Right: Building a Resilient, Distributed, Highly Available Open Source iSCSI SAN and I will talk in the Storage track, in English. Questions in German, of course, won’t be a problem.

As the conference organizers have asked speakers not to publicize the temporary schedule (for obvious reasons — hey it’s temporary), I can’t give the exact time and location yet. But if you want to hear about how you can replace your six-figure SAN with something much more open, much less locked-in and much less expensive, plan a trip to Berlin in early …

Yesterday’s webcast is now available for playback.

If you want a PDF of the slides, please leave a note on our web site.

Update, July 19, 2010: We have switched our webinar service provider. The webinar recordings are still available, albeit under a different URL, see this page for details.

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 backports.org) relatively soon.

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

As announced previously, our MySQL/Replication/Pacemaker webinar is on tomorrow (Wednesday April 7) at 1500 UTC. A few seats are still left; you may want to register quickly.
