I’m speaking at Percona Live, LinuxCon Europe, and linux.conf.au. And I just co-founded a new company.

I have a few busy weeks behind me, and even busier weeks ahead. If you’ve been wondering why recently I haven’t been updating this space too frequently, here’s why:

Yours truly and fellow ex-Linbiters Martin Loschwitz and Andreas Kurz have recently founded hastexo, an independent professional services organization focused on open-source high availability and disaster recovery. We are already offering both on-site and …

With OSCON in Portland under way (where LINBIT has a presence, of course), we are making three new documents available in the popular Tech Guides section of our web site.

• MySQL High Availability on the Pacemaker Cluster Stack is the definitive guide to setting up MySQL with DRBD on Pacemaker. A simple, step-by-step how-to which will have your highly available MySQL database up in no time.
• The DRBD Quick Reference has the most important DRBD …

Last week, the Linux-HA project made its Heartbeat 3.0.4 and Cluster Glue 1.0.7 release, and Pacemaker released 1.0.10 a few weeks back. Thanks to the amazing Simon Horman (horms to IRC regulars), those releases have been uploaded to Debian unstable (sid) yesterday.

What’s sid?

sid is the permanent code name of the Debian unstable distribution. It’s where package maintainers upload fresh builds and maintain the latest versions of distribution packages. It’s not meant for general consumption, …

When I read on the internetz that Alex Davies was about the publish a Packt book on MySQL HA I pinged my contacts at Packt and suggested that I'd review the book .

I've ran into Alex at some UKUUG conferences before and he's got a solid background on MySQL Cluster and other HA alternatives so I was looking forward to reading the book.

Alex starts of with a couple of indepth chapters on MySQL Cluster, he does mention that it's not a fit for all problems, but I'd hoped he did it a bit more prominently ... an upfront chapter outlining the different approaches and when which approach is a match could have been better. The avid reader now might be 80 pages into MySQL cluster before he realizes it's not going to be a match for his problem.

I really loved …

Thanks primarily to the efforts of Senko Rašić and Ante Karamatić, the Pacemaker cluster stack is being augmented with support for Upstart services. This is in addition to support for OCF resource agents and LSB/SysV init scripts, both of which have been supported in Pacemaker for years.

This is functionality now present in the upstream Mercurial trees, and we need testers to get in shape for release. Yes, that means you can help!

This is primarily relevant to you if you use a distribution with upstart as its default init daemon. This includes Ubuntu lucid, …

A little while back we did a webinar on using Pacemaker to fully automate MySQL replication. We now have a recording of that webinar available from our web site.

A couple of new webinar recordings are available from our web site:

• Upgrading to Pacemaker on Debian squeeze tells you all there is to know about upgrading to the Pacemaker cluster manager on the upcoming Debian release, “squeeze”.
• High Availability for Oracle databases shows you how to leverage the Linux cluster stack to deploy highly available Oracle databases.

Like our live webinars, the recordings are of course free of charge. Enjoy!

Martin Loschwitz, the longest-serving Debian Developer in our ranks, will present a walk-through of going from Linux clustering on Debian lenny (with Heartbeat 2.1.3, shudder) to squeeze (with Heartbeat 3 and Pacemaker). In this webinar you will learn everything you need to know about a painless migration to the new Linux cluster stack.
