community.general.lvol module – Configure LVM logical volumes

Note

This module is part of the community.general collection (version 8.4.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.general.

To use it in a playbook, specify: community.general.lvol.

Synopsis

  • This module creates, removes or resizes logical volumes.

Aliases: system.lvol

Parameters

Parameter

Comments

active

boolean

Whether the volume is active and visible to the host.

Choices:

  • false

  • true ← (default)

force

boolean

Shrink or remove operations of volumes requires this switch. Ensures that that filesystems get never corrupted/destroyed by mistake.

Choices:

  • false ← (default)

  • true

lv

string

The name of the logical volume.

opts

string

Free-form options to be passed to the lvcreate command.

pvs

list / elements=string

List of physical volumes (for example /dev/sda, /dev/sdb).

resizefs

boolean

Resize the underlying filesystem together with the logical volume.

Supported for ext2, ext3, ext4, reiserfs and XFS filesystems. Attempts to resize other filesystem types will fail.

Choices:

  • false ← (default)

  • true

shrink

boolean

Shrink if current size is higher than size requested.

Choices:

  • false

  • true ← (default)

size

string

The size of the logical volume, according to lvcreate(8) –size, by default in megabytes or optionally with one of [bBsSkKmMgGtTpPeE] units; or according to lvcreate(8) –extents as a percentage of [VG|PVS|FREE|ORIGIN]; Float values must begin with a digit.

When resizing, apart from specifying an absolute size you may, according to lvextend(8)|lvreduce(8) --size, specify the amount to extend the logical volume with the prefix + or the amount to reduce the logical volume by with prefix -.

Resizing using + or - was not supported prior to community.general 3.0.0.

Please note that when using +, -, or percentage of FREE, the module is not idempotent.

snapshot

string

The name of a snapshot volume to be configured. When creating a snapshot volume, the lv parameter specifies the origin volume.

state

string

Control if the logical volume exists. If present and the volume does not already exist then the size option is required.

Choices:

  • "absent"

  • "present" ← (default)

thinpool

string

The thin pool volume name. When you want to create a thin provisioned volume, specify a thin pool volume name.

vg

string / required

The volume group this logical volume is part of.

Attributes

Attribute

Support

Description

check_mode

Support: full

Can run in check_mode and return changed status prediction without modifying target.

diff_mode

Support: none

Will return details on what has changed (or possibly needs changing in check_mode), when in diff mode.

Notes

Note

  • You must specify lv (when managing the state of logical volumes) or thinpool (when managing a thin provisioned volume).
