What is a logical volume group?

Logical volumes are groups of information located on physical volumes. A hierarchy of structures is used to manage disk storage. Every physical volume in use belongs to a volume group (VG). All of the physical volumes in a volume group are divided into physical partitions (PPs) of the same size.
