ha-cluster-pacemaker-qdevice

Role for a basic configuring quorum device on pacemaker cluster ( Debian 10). This role complements the role https://github.com/OndrejHome/ansible.ha-cluster-pacemaker

This role can configure following aspects of pacemaker cluster:

install needed packages
create and configure users and groups for running quorum device
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.

Role tested on Debian 10.8 with ansible 2.10

Role Variables

user used for authorizing cluster nodes
```
cluster_user: 'hacluster'
```

qdevice_algorithm: 'ffsplit'
```

Example Playbook

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

  qdevice variable to set:
    qdevice_allowed_change: none
    qdevice_algorithm: 'ffsplit'
    cluster_node_is_arbiter: true
