1. Physical Volumes
Define raw disks or partitions. Avoid OS disk by default.
2. Volume Groups
Pool one or more PVs into VGs.
3. Logical Volumes
Carve LVs from VGs with linear, striped, mirrored, or thin options.

Common LVM Layouts
How LVM Works
LVM builds storage in layers. First, disks or partitions become physical volumes (PVs). PVs are grouped into a volume group (VG), a shared capacity pool. From that pool, logical volumes (LVs) are created and formatted with filesystems like XFS or ext4. This abstraction allows flexible resizing, snapshots, thin provisioning, and easier migration compared with fixed partition-only layouts.
