lvol – Configure LVM logical volumes

Synopsis

  • This module creates, removes or resizes logical volumes.

Parameters

Parameter Choices/Defaults Comments
active
boolean
    Choices:
  • no
  • yes ←
Whether the volume is activate and visible to the host.
force
boolean
    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
-
Free-form options to be passed to the lvcreate command.
pvs
-
Comma separated list of physical volumes (e.g. /dev/sda,/dev/sdb).
resizefs
boolean
added in 2.5
    Choices:
  • no ←
  • yes
Resize the underlying filesystem together with the logical volume.
shrink
boolean
    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
-
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).
