i) Enable dm in the kernel config.
ii) Install libdevmapper from the latest device-mapper release at www.sistina.com iii) Install LVM2 tools.
There is more documentation in the device-mapper and LVM2 packages.

i downloaded devicemapper.?.98?.tar.gz or something (the latest one) and i dont find much documentation in that, though i have looked into the INTRO file i didnt find others that from name appeared to be documentation.

How it is built up. Detailed information explaining to me how i can expand it, stuff like that. The LVM1 howto has a part that describes how the LVM1 is built up piece by piece, Physical Volumes, Physical Extends, ...

LVM2 uses the same model, the difference is it uses dm to implement it. Read the dmsetup man page for more info on how dm works.

Okay? thats not the impression i got from reading what documentation i could find (INTRO and dmsetup.8).

The driver is very different, but the userland tools still have exactly the same concepts of extents, PVs, LVs and VGs. The LVM2 tools have a few extra features, but other than that they are identical in use to the LVM1 ones.

One can always suggest the source code, and without understating the value of that, we can and will do better.

I'm sorry, you lost me somewhere? I dont mind looking at the code, but other documentation is nice too.

Sorry if I wasn't clear. We're violently agreeing.

If you're interested in writing your own targets I suggest you look at a couple of the trivial targets that already exist. Such as dm-linear.c, dm-stripe.c.

i am planning to write my own targets as a graduate project. My idea was encryption and possibly compression as well. (is anyone else doing any of these targets?)

Not as far as I know - it's considered good though.

Implementing an encrypting or compressing block device as a device-mapper target. It's been discussed, but as far as I know, nobody has started on it.

This is an idea that quite a few people have come up with, but as far as I know nobody is following up on it. I'd suggest you start with the encryption target, I think that's slightly easier since you can arrange for the encrypted data to be the same size as clear. You should then use the end_io() method to catch the buffer_heads after they've read the encrypted data and decrypt it there. The dm side should be very simple, yell if you have any questions.
