Product Overview

Logical Volume Manager

Description: Logical Volume Manager (LVM) is a disk management utility for Linux that allows administrators to create logical volumes out of physical disk partitions. This provides more flexibility in dynamically allocating storage space compared to using physical partitions directly.

LVM2

Description: LVM2 (Logical Volume Manager 2) is an open-source logical volume manager for Linux. It manages disk drives and similar mass-storage devices to provide large, flexible storage volumes for partitions and file systems.
