• authorize qorum device on each pacemaker nodes
• create or update qorum device cluster configuration (check allowed_qdevice_changes)

Requirements

This role depend on role ondrejhome.pcs-modules-2. You need a cluster fully configured to add your qdevice see : https://github.com/OndrejHome/ansible.ha-cluster-pacemaker.

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: cluster
  roles:
    - ha-cluster-pacemaker-qdevice
