ansibleでディスク領域を拡張する

ansibleでディスクの操作を行う方法はいくつかあるが、特に使いそうな２つをメモしておく
※ansibleのverによって名前が変わるmoduleがあるため注意

動作環境

ansible 2.7.10

partedでパーティションを切る

パーティションの情報をwith_itemsに持たせる。
複数パーティションを切る場合はwith_itemsに追加してやれば良い

roles/set_disk/tasks/main.yml

  - name: "disk settings"
  include: disk.yml
  with_items:
    - device: /dev/sdb
      num: 1
      label: gpt
      fstype: xfs
      mount_point: /home/foo/bar
      owner: hoge
  loop_control:
    loop_var: disk

roles/set_disk/tasks/disk.yml

- name: "parted {{ disk.device }}"
  parted:
    device: "{{ disk.device }}"
    number: "{{ disk.num }}"
    state: present
    label: "{{ disk.label }}"
  become: yes
  become_user: root

- name: "format {{ disk.device }}{{ disk.num }}"
  filesystem:
    dev: "{{ disk.device }}{{ disk.num }}"
    fstype: "{{ disk.fstype }}"
  become: yes
  become_user: root

- name: "get blkid for {{ disk.device }}{{ disk.num }}"
  shell: "blkid -s UUID -o value {{ disk.device }}{{ disk.num }}"
  register: uuid
  become: yes
  become_user: root

- name: "Mount up device by UUID for {{ disk.device }}{{ disk.num }}"
  mount:
    path: "{{ disk.mount_point }}"
    src: "UUID={{ uuid.stdout }}"
    fstype: "{{ disk.fstype }}"
    state: mounted
  become: yes
  become_user: root

- name: "chown mount point for {{ disk.device }}{{ disk.num }}"
  file:
    path: "{{ disk.mount_point }}"
    owner: "{{ disk.owner }}"
    group: "{{ disk.owner }}"
    state: directory
  become: yes
  become_user: root

LVMでディスクを拡張する

vgとlgの名前は特になければなんでも良い。
マウントポイントはpathに指定する。

roles/set_disk/tasks/main.yml

- name: create volume group
  lvg:
    vg: hoge
    pvs: "/dev/sdb"
  become: yes

- name: create logical volume
  lvol:
    vg: hoge
    lv: fuga
    size: +100%FREE
  become: yes

- name: make filesystem
  filesystem:
    fstype: xfs
    dev: /dev/hoge/fuga
    resizefs: yes
  become: yes

- name: mount disk
  mount:
    path: /home/foo/bar
    src: /dev/hoge/fuga
    fstype: xfs
    state: mounted
  become: yes

- name: "change permission for mount point"
  file:
    path: "/home/foo/bar"
    mode: "0755"
    owner: "hoge"
    group: "hoge"
    state: directory
  become: yes
