Ansible modules for configuring pacemaker cluster on CentOS/RHEL 6/7 and Fedora 29 systems.
If you are looking for a role that will configure a basic pacemaker cluster on CentOS/RHEL 6/7 or Fedora 29 systems, then check out the ondrejhome.ha-cluster-pacemaker role that uses the pcs-modules-2.
Note that modules manipulating with cluster configuration such as pcs_resource, pcs_constraint_*, pcs_property and pcs_resource_defaults should be run only from one of the cluster nodes in cluster by using either run_once: True or delegate_to: options.
RHEL: It is expected that machines will already be registered and subscribed for access to 'High Availability' or 'Resilient storage' channels.
