LVM2 is a userspace volume
management software. LVM2 needs a kernel driver called device-mapper
to provide virtual disks/partitions.
LVM2 reads and writes metadata to real disks and uses the device-mapper
to present virtual disks/partitions to the user. A partition created
with device-mapper is defined from ranges of sectors. Each range is
mapped to one or many real disks through a mapping. Possible mappings
include linear, striping, mirror, snapshot...
as far as i know, 2.6 kernel has LVM2 while 2.4 kernel has LVM1. so just like the module-init-tool. u need to download new LVM tools to support it. have u tried this? if u can get it work, then fine. if not, i will try to see if i can get some time this weekend to test it.
