new Ubuntu install using alt. cd and LVM (please help!)
 

HI, I'm not exactly new to using Linux, but I am not technically proficient in coping with what I'm needing to accomplish.

I want to install Ubuntu 12.04 using LVM and including all 4 physical hard drives in my computer.
so far I have been able to install using the alternative cd using LVM but only on one drive. once installed I haven't been able to add the other drives into the LVM (sorry if the terminology isn't correct)
here are the questions I need answered and maybe help with.
1. can I get the Ubuntu alt. cd installer to use all 4 drives as one logical volume during the install? if so how?
2. if the answer to question 1 is no, can I add the other 3 drives to the logical volume after the install? if so how?

someone suggested using Fedora as it makes it easy to accomplish what I want, but I'm having reliability issues that I never had with Ubuntu and I'd like to move back.
here is what my current LVM looks like under Fedora 14:

here are some of my system stats.
AMD Phenom II X6 1100T processor
16gb ram
4x2tb hdd's

You can add new disks (as pvs) anytime after the install. Then add the pv to the vg, then expand any lv in need.
There is a how-to on tldp.org, and redhat have/had good LVM doco as well.
