Pacemaker

Ansible role to configure Pacemaker.

Developed on CentOS 6.5 with Pacemaker version 1.1.10.

This role provides several modules to manage Pacemaker configuration with pcs tool. See example below for details.

pcs is not available on Debian Wheezy, where crm is the tool available. In a future we may add support for it.

You will likely want to use Pacemaker in conjunction with Corosync. Checkout sbitmedia.corosync, and make sure this role is included later. See example below.
