If you're building a RAID array just for your session space and not the 
whole system, then I'd think you can probably get away without having to 
reinstall your OS.  You might need to enable some more settings in your 
kernel config to support your particular hardware and roll a new kernel, 

Note that RAID 0+1 requires a minimum of 4 disks - a pair to stripe data 
across another pair to mirror the first pair.  Your motherboard would need 
to have 4 SATA ports if you plan to use all SATA drives, or you'd need a 
PCI or PCI express expansion card (again depending on your motherboard) 
SATA controller that has more ports on it.  Software RAID can also place 
more load on your CPU, but should be enough to get you started, then if 
you decide that you want to move to a hardware RAID in the future, then 
you can do that.

As far as a good howto, that really depends on your distro, which I 
believe is Fedora Core 7, correct?  I didn't come across a howto that was 
specific to Fedora, but a good starting point is the info in the Linux 
Documentation Project, at:


It also provides more information on the different RAID types and some of 
their pros and cons.  For something that's more specific to Fedora, you 
may want to check some of the Fedora forum sites, like 

Hope this helps
