This is LVM2, the rewrite of The Linux Logical Volume Manager.
|
LVM supports enterprise level volume management of disk and
|
disk subsystems by grouping arbitrary disks into volume
|
groups. The total capacity of volume groups can be allocated
|
to logical volumes, which are accessed as regular block
|
devices.
|
|
The Linux Kernel Device Mapper is the LVM
|
(Linux Logical Volume Management) Team's implementation of a
|
minimalistic kernel-space driver that handles volume
|
management, while keeping knowledge of the underlying device
|
layout in user-space. This makes it useful for not only LVM,
|
but EVMS, software raid, and other drivers that create
|
"virtual" block devices.
