6.2. Logical Volume Manager

The set of operating system commands, library subroutines, and other tools that allow you to establish and control logical volume storage is called the Logical Volume Manager (LVM). The LVM controls disk resources by mapping data between a more simple and flexible logical view of storage space and the actual physical disks.

6.2.1. LVM configuration data

The data that describes the components of the LVM is not kept in one place. It is important to understand that this descriptive data about volume groups, logical volumes, and physical volumes is kept in several places.
