[olug] Upgrading to FC4 from FC3

[A-Wal]

Well, this raises another couple of questions.  Here's my current hard 
drive layout.  I have one 200Gb ATA hard drive plugged into the MB, and 
two identical 17Gb scsi plugged into a scsi PCI card.  The MB has a raid 
controller on it, but to date I have never used it.  Unfortunately, the 
raid controller on the MB only allows you to use two ATA hard drives, 
and I only have one.  I was wanting to learn how to setup a raid under 
Linux, but will have to do it using my two scsi hard drives instead.  My 
one ATA hard drive is used for dual windows/Linux.  It has one 100Gb 
partition that windows uses, and I use the other 100Gb for playing with 
Linux.  So far Grub has worked great for dual booting into windows.  The 
idea would be to setup a raid0 using my two 17Gb scsi hard drives, and 
use it for / to speed up overall performance in Linux, and then use the 
other 100Gb from my ATA hard drive for things like /home, /tmp, /usr, 
etc that aren't as performance dependant.  I know that Linux has been 
using scsi since it was pretty much first created, and I was wondering 
if there was a way to setup my two scsi hard drives in raid0 using Linux 
itself, since I can't use my raid controller on the MB.
