Since the new MySQL Pacemaker resource agent supporting PRM is now included in version 3.9.3 of the official Pacemaker resource agents package and things have stabilized a bit, I have been able to write some documentation. I wrote a first draft of the PRM documentation that is likely far from perfect, but I hope it will be useful and improve rapidly. The PRM documentation is available here. Comments and suggestions are welcome, please use the PRM discuss or the PRM devel mailing lists instead of replying to the blog post directly.
