Module Usage

There's a bit of a chicken and egg situation going on, because some commands can only be run if everything is set up. So, assuming that one filer is already up and running, we can use one as delegate:

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

This can then be used with the modules if required:

- 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 }}'

Configuration can be done for 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
