ansible-pacemaker2's Introduction

ansible-pacemaker2

Ansible modules set for Pacemaker, cluster resource manager for Linux/*NIX

It contains below:

pacemaker_resource: configure a pacemaker resource, including clone and master ones
pacemaker_resource_group: configure a pacemaker resource group
pacemaker_resource_default: configure default resource parameters
pacemaker_location: configure a location constraint
pacemaker_colocation: configure a colocation constraint
pacemaker_order: configure an order constraint
pacemaker_order_set: configure an order-set constraint
pacemaker_property: configure pacemaker cluster properties

They depend on cibadmin command.
