Main components and entities of the Logical Volume Management (LVM) system:
- Physical Volume (PV) — a physical disk or partition used by LVM.
- Volume Group (VG) — a group of physical volumes combined into a single logical space.
- Logical Volume (LV) — a logical partition created within a Volume Group, used as a regular filesystem partition.
- Physical Extent (PE) — the smallest block of space on a physical volume allocated for logical volumes.
- Logical Extent (LE) — a block of space within a logical volume, corresponding to one or more physical extents.
LVM allows flexible management of disk space: expanding, shrinking, and moving logical volumes without data loss.
