Pacemaker is the resource manager for the ClusterLabs open-source high-availability cluster stack. It coordinates the configuration, start-up, monitoring, and recovery of interrelated services across all cluster nodes.
Pacemaker was initially created by main architect and lead developer Andrew Beekhof andrew@beekhof.net with the aid of project catalyst and advocate Lars Marowsky-Brée lmb@suse.de.
Many, many developers have contributed significantly to the project since. The git log is the definitive record of their greatly appreciated contributions.
The wider ClusterLabs community is another essential aspect of the project's existence, especially the many users who participate in the mailing lists, blog about HA clustering, and otherwise actively make the project more useful.
Pacemaker source code is distributed via Github.
From there, you can clone or download the repository to get the latest development code, or download one of the official releases.
