What is Pacemaker?

Pacemaker is an advanced, scalable high-availability cluster resource manager.

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.

How do I install Pacemaker?


What higher-level interfaces to Pacemaker are available?

There are multiple user interfaces for Pacemaker, including command-line tools, graphical user interfaces and web frontends. The crm shell used to be included in the Pacemaker source tree, but is now a separate project.

This is not an exhaustive list:

Can I convert some other cluster configuration to Pacemaker?

clufter is a general-purpose tool for converting one cluster representation format to another. Among other possibilities, it can convert from a cluster based on rgmanager with CMAN to a one based on pacemaker with corosync. See its documentation for details.
