Pacemaker

What is Pacemaker?

Pacemaker is an advanced, scalable High-Availability cluster resource manager for Linux-HA (Heartbeat) and/or Corosync.

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.

For more information look at:

User interfaces / shells

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