As a follow-up to my original article on recursion in Puppet, and in my attempt to Push Puppet (to its limit), I’ll now attempt some more advanced recursion techniques in Puppet. In my original recursion example, the type does recurse, … Continue reading
Ironically, one of the reasons that I started writing Puppet code, was so that I could spend more time designing and building, and less time writing documentation. I suppose I’m a victim of my success, because Puppet-Gluster has grown large … Continue reading

In my attempt to push puppet to its limits, (for no particular reason), to develop more powerful puppet modules, to build in a distributed lock manager, and to be more dynamic, I’m now attempting to build a Finite State Machine … Continue reading
Hey there, I’ve done a bit of puppet-gluster hacking lately to try to squeeze some extra features and testing in before Linuxcon. Here’s a short list: SELinux fixes to keep Dan Walsh happy :) Ping and status checks before volume … Continue reading
