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

This example is taken from [`molecule/default/converge.yml`](https://github.com/robertdebock/ansible-role-lvm/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

  roles:

    - role: robertdebock.lvm

      # It's difficult to test this in CI.

      # lvm_volume_groups:

      #   - name: first

      #     pvs:

      #       - /dev/loop0

      # There is no device mapper in containers.

      # lvm_logical_volumes:

      #   - name: first

      #     vg: first

      #     size: 100%FREE

      #     opts: --type cache-pool

```

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

```yaml

---

- name: Prepare

  hosts: all

  become: true

  gather_facts: false

  roles:

    - role: robertdebock.bootstrap

  # tasks:

  #   - name: create disk.img

  #     command: dd if=/dev/zero of=/disk.img bs=1M count=100

  #     args:

  #       creates: /disk.img

  #   - name: create /dev/loop0

  #     command: mknod /dev/loop0 b 7 8

  #     args:

  #       creates: /dev/loop0

  #     notify:

  #       - link disk.img to /dev/loop0

  # handlers:

  #   - name: link disk.img to /dev/loop0

  #     command: losetup /dev/loop0 /disk.img

```

## [Role Variables](#role-variables)

The default values for the variables are set in [`defaults/main.yml`](https://github.com/robertdebock/ansible-role-lvm/blob/master/defaults/main.yml):

```yaml

---

# defaults file for lvm

# Per lvm a size can be set, if it's not set, use this value.

lvm_default_pesize: 32

# A list of volume groups.

# lvm_volume_groups:

#   - name: first

#     pvs:

#       - /dev/sdb1

#   - name: second

#     pvs:

#       - /dev/sdb2

#     pesize: 128K

#   - name: third

#     pvs:

#       - /dev/sdb3

#       - /dev/sdb4

# A list of volumes.

# lvm_logical_volumes:

#   - name: first

#     vg: first

#     size: 512

#     opts: --type cache-pool

```
