Pacemaker is the Project Successor

  • {i} Note <!> Pacemaker is the Project Successor of "Heartbeat Version 2".

If you are looking for documentation and information for the "Version 2" heartbeat, you should really be reading the Pacemaker home page at

If you are stuck with Heartbeat 2.1.3 or Heartbeat 2.1.4, the best fitting Documentation is probably that for Pacemaker 0.6, which can also be found on the Pacemaker Documentation page {OK}

Quoting the first paragraph from v2 (in this wiki):

Special Note for Version 2 Users

The CRM is now maintained as an independent project called Pacemaker and now has many new features including support for the OpenAIS cluster stack.

Heartbeat 2.1.4 was the last release to contain the CRM or "Version 2 Resource Manager" and since then all development and maintenance is performed as part of the Pacemaker project and all CRM code has been removed from Heartbeat.
