I was unclear. With a RAID controller, you *should* be able to merge a
large number of disks into a single RAIDset and have that occur in
hardware, saving cycles from doing other sophisticated tasks (like LVM).
What do you expect to gain from using LVM?

That wouldn't have helped against *THIS* problem. You wouldn't have been
able to use the Promise chipsets *at all*, even for non-RAID use.

Various forms of hardware and software RAID have been in the Linux
kernels for ages. ATARAID is not the problem. It's the Promise chipset
and drivers for it: be *very* clear on what you need.
Do you know the chipset of the FasTrak system? Can you have someone boot
the damn thing and write down what it says? And what is your disk layout
like?
