LVM2 is a package for managing logical volumes from one or more hard drives.
LVM provides a great flexibility for the space occupied by each volume. In fact, each volume can be resized, deleted or added.
LVM has 3 layers :
- Physical volumes
- Volume groups
- Logical volumes
LVM also allows you to quickly create a snapshot of your LVM system.
To create your physical volumes, volume groups and your logical volumes, refer to the tutorial listed below.
