The total capacity of volume groups can be allocated 11 to logical volumes, which are accessed as regular block 12 devices. 13 14 The Linux Kernel Device Mapper is the LVM 15 (Linux Logical Volume Management) Team's implementation of a 16 minimalistic kernel-space driver that handles volume 17 management, while keeping knowledge of the underlying device 18 layout in user-space. This makes it useful for not only LVM, 19 but EVMS, software raid, and other drivers that create 20 "virtual" block devices. 21 22 http://www.sourceware.org/lvm2/ 23 24if BR2_PACKAGE_LVM2 25 26config BR2_PACKAGE_LVM2_STANDARD_INSTALL 27 bool "standard install instead of only dmsetup" 28 default y 29 select BR2_PACKAGE_LIBAIO 30 help 31 Install the standard suite of lvm2 programs.
