14 LVM
15 Logical volume manager. The LVM allows to allocate space on block
16 devices more dynamically than with traditional partitions. The block
17 devices are managed as physical volumes (PVs) that are grouped in volume
18 groups (VGs). Space can be allocated as logical volumes (LVs) that can be
19 formatted using regular file system tools. LVs can be resized without
20 reboot. LVM provides snapshot functionality that is useful for backup and
21 upgrade procedures.
