I've not seen a howto for this, but the steps are reasonably straight
forward. I've done this myself recently after deciding I didn't need my
Windoze partition any more!

Use cfdisk to change the partition type of your ntfs partition to 8E.
Use pvcreate to create a physical volume out of the partition.
Use vgcreate to create a volume group (calling it VG01, for example;
pick your own name) containing just the physical volume you just
created.
Use lvcreate (called home say, pick your own meaningful name) to create
on or more logical volumes in the volume group just created.
Create a file system in the logical volume with mkfs, e.g.,
	mkfs -t ext3 /dev/VG01/home

If you call the volume group VG1 and the logical volume 'home', then it
can be mounted from /dev/VG1/home onto any suitable mount point.

I would read the man pages carefully!

There is a good general howto on LVM at http://tldp.org/HOWTO/LVM-HOWTO/

Have fun!

Regards,
Tony.
