How to Use the Modules

Some commands need a server to be running first. So, once you have a filer (file server) working, you can randomly choose one as a delegate:

- name: find our delegate
  set_fact:
    mmdelegate: '{{ groups.filer | random }}'

You can then use this delegate in your tasks:

- name: add node
  mmnode:
    name: node007
  delegate_to: '{{ mmdelegate }}'

- name: add to nodeclass
  mmnodeclass:
    node: node007
    nodeclass: compute
  delegate_to: '{{ mmdelegate }}'

- name: set license
  mmlicense:
    node: node007
    license: client
  delegate_to: '{{ mmdelegate }}'

You can also configure node classes:

- name: small pagepool for compute
  mmconfig:
    node: compute
    key: pagepool
    value: 4G
  run_once: yes

- name: fat pagepool for filer
  mmconfig:
    node: filer
    key: pagepool
    value: 256G
  run_once: yes
