Linux Storage Role

This role allows users to configure local storage with minimal input.

As of now, the role supports managing file systems and mount entries on

• unpartitioned disks
• lvm (unpartitioned whole-disk physical volumes only)

Role Variables

pools

The pools variable is a list of pools to manage. Each pool contains a nested list of volume dicts as described below, as well as the following keys:

name

This specifies the name of the pool to manage/create as a string. (One example of a pool is an LVM volume group.)

type

This specifies the type of pool to manage. Valid values for type: lvm.

disks

This specifies the set of disks to use as backing storage for the pool.

volumes

The volumes variable is a list of volumes to manage. Each volume has the following variables:

name

This specifies the name of the volume.

type

This specifies the type of volume on which the file system will reside. Valid values for type: lvm(the default) or disk.

disks

This specifies the set of disks to use as backing storage for the file system. This is relevant for volumes of type disk or partition.

size

The size specifies the size of the file system. The format for this is intended to be human-readable, eg: "10g", "50 GiB", or "100%" (use all available space on the specified disks).

fs_type

This indicates the desired file system type to use, eg: "xfs"(the default), "ext4", "swap".

fs_label

The fs_label is a string to be used for a file system label.

fs_create_options

The fs_create_options specifies custom arguments to mkfs as a string.

mount_point

The mount_point specifies the directory on which the file system will be mounted.

mount_options

The mount_options specifies custom mount options as a string, eg: 'ro'.
