LVM2

• (If you use an old Knoppix version you may need to install LVM tools first. Version 5.0.1 already has the packages and dm-mod module loaded, and the following first steps are not necessary.)

# modprobe dm-mod
# apt-get update
# apt-get install lvm-common lvm2

If you needed the above steps, remember that the tools are in /lib/lvm-200 but if you don't want to type the complete path, you may link them into /usr/bin.

# lndir /lib/lvm-200/ /usr/sbin/

• To use existing volume groups you have to activate them.

# vgscan
# vgchange -a y

• To mount it, find the VG name, then find that name in /dev/

# vgdisplay | head
--- Volume group ---
VG Name               music2_vg

# ls /dev/music2_vg/*
/dev/music2_vg/lvol1

# mount /dev/music2_vg/lvol1 /mnt/tmp
# ls /mnt/tmp
