<div>*<u>If you use an old Knoppix version</u> you may need to install LVM tools first. Version 5.0.1 and later (at least) already have the packages and dm-mod module loaded, and the following first steps are not necessary.<br />
<br />
# modprobe dm-mod<br />
# apt-get update<br />
# apt-get install lvm-common lvm2<br />
<br />
If you needed the above steps, remember that the tools are in /lib/lvm-200 <br />
but if you don't want to type the complete path, you may link them into /usr/bin.<br />
<br />
# lndir /lib/lvm-200/ /usr/sbin/<br />
<br />
<br />
*To use existing volume groups you have to activate them.<br />
-----<br />
<br />
# vgscan<br />
# vgchange -a y<br />
<br />
*To mount a logical volume first find out what it is called, unless you know already. Use lvs or vgdisplay/lvdisplay for this.<br />
-----<br />
# lvs<br />
LV VG Attr LSize Origin Snap% Move Log Copy%<br />
home vg -wi-ao 2.09G<br />
var vg -wi-ao 1.32G<br />
<br />
*In this example, the volume group 'vg' contains two logical volumes, called 'home' and 'var'. To mount the 'home' volume:<br />
-----<br />
<br />
# mount /dev/vg/home /mnt/tmp<br />
# ls /mnt/tmp<br />

<br />
*The volumes can be accessed with names '''/dev/<vg>/<lv>''' or '''/dev/mapper/vg-lv'''. For example, the file /dev/vg/home is a symbolic link to /dev/mapper/vg-home, and you can use either name to mount it.</div>82.93.37.155
