opts
(added in 2.0)
 no
Free-form options to be passed to the lvcreate command
pvs
(added in 2.2)

shrink
(added in 2.2)
 no True
shrink if current size is higher than size requested
size
 no
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)
 no
The name of the snapshot volume
state
 no present
  • present
  • absent
Control if the logical volume exists. If present and the volume does not already exist then the size option is required.
vg
