A great GUI tool for managing and creating LVs. But sadly, doesn't exist or work past Rocky 8. When creating a Volume Group BLIVET creates the Partition, Physical Volume, and Volume Group in one swift move.

Command Alternative

# List Physical Volumes (PVs)
pvs

# List Volume Groups (VGs)
vgs

# List Logical Volumes (LVs)
lvs

Create a New LVM Structure

1. Create a Physical Volume (PV) on /dev/sdb

pvcreate /dev/sdb

2. Create a Volume Group (VG) named my_vg

vgcreate my_vg /dev/sdb

3. Create a Logical Volume (LV) named my_lv (10GB size)

lvcreate -L 10G -n my_lv my_vg
