config BR2_PACKAGE_LVM2 bool "lvm2 & device mapper" depends on BR2_LARGEFILE depends on BR2_USE_MMU # needs fork() help 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. config BR2_PACKAGE_LVM2_DMSETUP_ONLY bool "install dmsetup only" depends on BR2_PACKAGE_LVM2 help Install dmsetup only and skip the LVM2 suite. config BR2_PACKAGE_LVM2_APP_LIBRARY bool "install application library" depends on BR2_PACKAGE_LVM2 depends on !BR2_PACKAGE_LVM2_DMSETUP_ONLY help Install application library (liblvm2app). comment "lvm2 requires a toolchain with LARGEFILE support" depends on !BR2_LARGEFILE
