lvol - Configure LVM logical volumes

Synopsis

  • This module creates, removes or resizes logical volumes.

Parameters

Parameter
Choices/Defaults
Comments
active
(added in 2.2)
    Choices:
  • no
  • yes ←
Whether the volume is activate and visible to the host.
force
(added in 1.5)
    Choices:
  • no ←
  • yes
Shrink or remove operations of volumes requires this switch. Ensures that that filesystems get never corrupted/destroyed by mistake.
lv
The name of the logical volume.
opts
(added in 2.0)
Free-form options to be passed to the lvcreate command.
pvs
(added in 2.2)
Comma separated list of physical volumes (e.g. /dev/sda,/dev/sdb).
resizefs
(added in 2.5)
    Choices:
  • no
  • yes ←
Resize the underlying filesystem together with the logical volume.
shrink
(added in 2.2)
    Choices:
  • no
  • yes ←
Shrink if current size is higher than size requested.
size
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]; Float values must begin with a digit. Resizing using percentage values was not supported prior to 2.1.
snapshot
(added in 2.1)
The name of the snapshot volume
state
    Choices:
  • absent
  • present ←
Control if the logical volume exists. If present and the volume does not already exist then the size option is required.
thinpool
(added in 2.5)
The thin pool volume name. When you want to create a thin provisioned volume, specify a thin pool volume name.
vg
The volume group this logical volume is part of.

Notes

Note

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