lvcreate [OPTIONS] VolumeGroup
DESCRIPTION
lvcreate creates a logical volume in an existing volume group. Logical volumes are virtual block devices that can span multiple physical volumes and support features like snapshots, striping, and mirroring.

-L, --size size
Specify size (e.g., 10G, 1500M)-l, --extents extents
Specify size in extents or percentage (%VG, %FREE, %PVS)-n, --name name
Name for the logical volume-s, --snapshot
Create a snapshot volume-T, --thin
Create a thin pool or thin volume--thinpool pool
Specify thin pool for thin volume-m, --mirrors count
Create a mirrored volume-i, --stripes count
Number of stripes for striped volume
CAVEATS
The volume group must have sufficient free space. Logical volume names must be unique within a volume group. After creation, a filesystem must be created on the LV before mounting.
