Logical Volume Manager (LVM)
About LVM Logical Volume Manager
Storage virtualization known as logical volume management (LVM) gives system administrators greater flexibility in controlling disk storage capacity than traditional partitioning. The operating system's device-driver stack is home to this kind of virtualization technology.
As a logical volume management tool, it allows for the allocation of disk space as well as striping, mirroring, and resizing of logical volumes. A hard disk or group of drives is allotted to one or more physical volumes using LVM. Other block devices that may span two or more disks can host LVM physical volumes.
Why is LVM Logical Volume Manager important?
Increased abstraction, flexibility, and control are LVM's key benefits. Meaningful names for logical volumes include "databases" and "root backup." Additionally, volumes may be dynamically enlarged as storage needs change, moved between physical devices in the pool on a running system, or exported.

- System or Network Administrators
