    - A logical volume manager (LVM) is a software package available with most operating systems.

    - Sometimes it is called a logical disk manager (LDM).

    - It allows pieces of multiple physical disks to be combined into a single contiguous address space that appears as one disk to higher layers of software.

    - An LVM can make the logical volume have better capacity, performance, reliability, and availability characteristics than any of the underlying physical disks.

    - It uses techniques such as mirroring, striping, concatenation, and RAID 5 to implement these characteristics.

    - Some LVMs allow the characteristics of a logical volume to be changed after it is created, even while it is in use.

    - The volume may be resized or mirrored, or it may be relocated to different physical disks.
