lvol – Configure LVM logical volumes¶
Synopsis¶
This module creates, removes or resizes logical volumes.
Parameters¶
| Parameter | Choices/Defaults | Comments |
|---|---|---|
|
active
boolean
added in 2.2 |
|
Whether the volume is activate and visible to the host.
|
|
force
boolean
|
|
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
boolean
added in 2.5 |
|
Resize the underlying filesystem together with the logical volume.
|
|
shrink
boolean
added in 2.2 |
|
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
-
|
|
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).
