Defined Type: lvm::volume

Defined in:
modules/lvm/manifests/volume.pp

Overview

Define: lvm::volume

This defined type will create a logical_volume with the name of the define and ensure a physical_volume, volume_group, and filesystem resource have been created on the block device supplied.

Parameters

ensure

Can only be set to cleaned, absent or

present. A value of present will ensure that the physical_volume, volume_group, logical_volume, and filesystem resources are present for the volume. A value of cleaned will ensure that all of the resources are absent Warning this has a high potential for unexpected harm use it with caution. A value of absent will remove only the logical_volume resource from the system.

pv

The block device to ensure a physical_volume has been

created on. [vg] The volume_group to ensure is created on the physical_volume provided by the pv parameter.

fstype

The type of filesystem to create on the logical

volume. [size] The size the logical_voluem should be.

Examples

Provide some examples on how to use this type:

lvm::volume { 'lv_example0':
  vg     => 'vg_example0',
  pv     => '/dev/sdd1',
  fstype => 'ext4',
  size => '100GB',
}
