Depends upon how much more disk you need, what kind of disks you have in
your junk box and how much you value your time. Raid 0 will give you better
performance with two disks than you would get with either one, since you get
the advantage of overlap because of striping. It's also cheap enough if you
have spare IDs and junk disks. Booting off of a RAIDed root device can be a
bit dicey, but it is not impossible. You will probably have to back up,
boot from your floppy rescue disks and reload in order to reconfigure your
system. Tedious, but not terribly complicated. On the other hand, with the
price of new 8.4Gb EIDE drives at ~$US100 these days, you might want to just
buy a shiney new hard drive and ditch your old one. It's hard to justify
putting a lot of effort into it unless you're cheap, like me. :-)
Good luck!

Subject: Is Raid as frought as it looks?
I am running out of space on my root device and am thinking of adding
another scsi disk using Raid - linear or 0 (whichever is the easiest!). Is
software Raid as fearsome as all the docs I read suggest? Ideally, I'd like
to be able to hitch the disk up, add a couple of lines to my rc startup file
- job done! Am I asking for the moon? Would I be better off getting out my
wallet for a bigger (IDE) HD?
