I've been meaning to get that USB code off my chest for a while, so I
guess you struck a nerve :-)

In that case, I would setup 4 LVs. One on each drive. (pvcreate,
vgcreate, lvcreate, mkfs, etc.)
Then, use md to create a RAID5 array from those LVs. That gives you
expandability and RAID.
As I said in my last post, I haven't successfully used md, so I don't
have answers off the top of my head. I'm sure there is a forum
somewhere that can help. You might try a search on that gossamer
threads (?) site. If I have time, I will look into it too.
Regards,
JJ

Help everyone. If you can't do that, then at least be nice.
