LVM version >= 2.0 found.
Just before you extrapolate mountlist to include RAID partitions,
extrapolate it to include the following LVM drives and partitions:-
>>>>> /dev/sda5 
To get started, type:-
(insmod dm-mod)
(insmod dm_mod)
# lvm vgchange -an
# echo y | lvm pvcreate -ff /dev/sda5
# lvm vgscan

Create and activate the VG's (volume groups).
# lvm vgcreate root-vg -l 0 -p 0 -s 4.00m /dev/sda5 
# lvm vgchange -a y root-vg

Finally, create the LV's (logical volumes).
# lvm lvcreate -L 4096m -r auto -n lv_root root-vg
# lvm lvcreate -L 1024m -r auto -n lv_swap root-vg
# lvm lvcreate -L 10240m -r auto -n lv_home root-vg
# lvm lvcreate -L 3072m -r auto -n lv_tmp root-vg
# lvm lvcreate -L 6144m -r auto -n lv_usr root-vg
# lvm lvcreate -L 6144m -r auto -n lv_var root-vg
# lvm lvcreate -L 12288m -r auto -n lv_opt root-vg

# lvm vgscan
Now you may format the LV's:-
(mkfs -t foo /dev/root-vg/lv_root or something like that)
(mkfs -t foo /dev/root-vg/lv_swap or something like that)
(mkfs -t foo /dev/root-vg/lv_home or something like that)
(mkfs -t foo /dev/root-vg/lv_tmp or something like that)
(mkfs -t foo /dev/root-vg/lv_usr or something like that)
(mkfs -t foo /dev/root-vg/lv_var or something like that)
(mkfs -t foo /dev/root-vg/lv_opt or something like that)

Finally, to shut down and delete the volumes, do this:-
(lvm lvremove -f /dev/root-vg/lv_root)
(lvm lvremove -f /dev/root-vg/lv_swap)
(lvm lvremove -f /dev/root-vg/lv_home)
(lvm lvremove -f /dev/root-vg/lv_tmp)
(lvm lvremove -f /dev/root-vg/lv_usr)
(lvm lvremove -f /dev/root-vg/lv_var)
(lvm lvremove -f /dev/root-vg/lv_opt)
(lvm vgchange -a n root-vg)
(lvm vgremove root-vg)
(rmmod dm-mod & rmmod dm_mod & )
