Introduction to LVM2
The LVM2 package is a package that
manages logical partitions. It allows spanning of file systems
across multiple physical disks and disk partitions and provides for
dynamic growing or shrinking of logical partitions.
This package is known to build and work properly using an LFS-7.4

Enable the following option in the kernel configuration and
recompile the kernel:
There are several other Device Mapper options in the kernel
beyond those listed below. In order to get reasonable results if
running the regression tests, all must be enabled either
internally or as a module.
Device Drivers --->
Multiple devices driver support (RAID and LVM): Y
Device mapper support: Y or M
Crypt target support: (optional)
Snapshot target: (optional)
Mirror target: (optional)
Installation of LVM2
Install LVM2 by running the
./configure --prefix=/usr \
The check command must be run as the
root user. Also the tests are known to hang if
at least one partition on a hard drive is not set up as a Linux LVM
partition (type 8e00). To test the results, issue: make check as the
