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.

• Issues/Bugs
• Mailing list.

Important information about the crm shell

Since late-April, the crm shell is no longer included in the Pacemaker source tree. This change was made at the author's request as it is now maintained as a separate project at https://savannah.nongnu.org/projects/crmsh/
