The name of the logical volume.
opts
(added in 2.0)
no
Free-form options to be passed to the lvcreate command
pvs
(added in 2.2)
no
Comma separated list of physical volumes e.g. /dev/sda,/dev/sdb
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
yes
The volume group this logical volume is part of.
