## [Example Playbook](#example-playbook)

This example is taken from [`molecule/default/converge.yml`](https://github.com/robertdebock/ansible-role-storage/blob/master/molecule/default/converge.yml) and is tested on each push, pull request and release.

```yaml
---
- name: Converge
  hosts: all
  become: true
  gather_facts: true

pre_tasks:
    # For testing in containers, a loopback device is created in `prepare.yml`.
    # The device created in `prepare.yml` is picked up here.
    # Normally you would point to /dev/sd*.
    - name: Read loop device from disk
      ansible.builtin.slurp:
        src: /loopback-devicename.txt
      register: loopback_devicename

roles:
    - role: robertdebock.storage
      # Partitioning a loopback device is not supported by parted.
      # storage_partitions:
      #   - name: "{{ loopback_devicename.content | b64decode }}"
      #     number: 1
      #     part_end: 100%
      #     label: gpt
      storage_volumegroups:
        - name: data
          devices:
            - "{{ loopback_devicename.content | b64decode }}"
          size: 4
      storage_volumes:
        - name: test1
          vg: data
          size: 1G
          opts: --zero n
      storage_filesystems:
        - name: /dev/data/test1
          fstype: xfs
      # Mounting is not idempotent for:
      # - debian:bullseye
      # - ubuntu:focal
      # - ubuntu:bionic
      # storage_mounts:
      #   - name: /mnt/test
      #     src: /dev/data/test1
      #     fstype: xfs
      #     owner: root
      #     group: root
      #     mode: "0755"
```

The machine needs to be prepared. In CI this is done using [`molecule/default/prepare.yml`](https://github.com/robertdebock/ansible-role-storage/blob/master/molecule/default/prepare.yml):

```yaml
---
- name: Prepare
  hosts: all
  become: true
  gather_facts: false

roles:
    - role: robertdebock.bootstrap

tasks:
    # These are "cleanup" tasks, to make sure the test is run in a non-biased environment.
    - name: Unmount /mnt/test
      ansible.posix.mount:
        path: /mnt/test
        state: absent

- name: Install lvm2
      ansible.builtin.package:
        name: lvm2

- name: Remove lv
      community.general.lvol:
        vg: data
        lv: test1
        state: absent
        force: true

- name: Remove all loop devices
      ansible.builtin.command:
        cmd: losetup -D
      changed_when: true
      when:
        - ansible_facts['distribution'] != "Alpine"

- name: Remove loop_device on Alpine
      when:
        - ansible_facts['distribution'] == "Alpine"
      block:
        - name: Find loop devices
          ansible.builtin.command:
            cmd: losetup -a
          register: loop_devices
          changed_when: false

- name: Remove loop device
          ansible.builtin.command:
            cmd: "losetup -d {{ item | split(':') | first }}"
          changed_when: true
          loop: "{{ loop_devices.stdout_lines }}"

# Since we're in a container, let's create a file.
    # Normally you would not require this, as `/dev/sd*` (or so) would be used.
    - name: Create a 4GB file
      community.general.filesize:
        path: /blockdevice.img
        size: 4G
        owner: root
        group: root
        mode: "0644"

- name: Find first unused loop device
      ansible.builtin.command:
        cmd: losetup -f
      register: loop_device
      changed_when: false

- name: Store loop device on disk
      ansible.builtin.copy:
        content: "{{ loop_device.stdout }}"
        dest: /loopback-devicename.txt
        owner: root
        group: root
        mode: "0644"

- name: Create loop device
      ansible.builtin.command:
        cmd: losetup {{ loop_device.stdout }} /blockdevice.img
      changed_when: true
```

# storage_mounts:
#   - name: /var

#     group: root
#     mode: "0755"
#     opts: defaults
