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. http://www.sourceware.org/lvm2/ if BR2_PACKAGE_LVM2 config BR2_PACKAGE_LVM2_STANDARD_INSTALL bool "standard install instead of only dmsetup" default y if !BR2_PACKAGE_LVM2_DMSETUP_ONLY # legacy 2013.11 help Install the standard suite of lvm2 programs.
