What is Pacemaker?

Pacemaker is an advanced, scalable high-availability cluster resource manager. It runs on top of a cluster communication layer, either Corosync or Linux-HA's Heartbeat.

It supports "N-node" clusters with significant capabilities for managing resources and dependencies.

It will run scripts at initialization, when machines go up or down, when related resources fail and can be configured to periodically check resource health.

Who is Pacemaker?

Pacemaker is distributed by ClusterLabs.

Pacemaker was initially created by main architect and lead developer Andrew Beekhof, with the aid of project catalyst and advocate Lars Marowsky-Brée

Many, many developers have contributed significantly to the project since. The git log is the definitive record of their greatly appreciated contributions.

The wider community of Pacemaker users 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.
