2.2.14-20 is not a 'stock' kernel, by my terms anyway. By 'stock', most
people (well, me, anyway) mean '100% Prime Torvalds'. RedHat, SuSE,
Mandrake - hell, practically everyone - do not distribute these kernels. The
'-20' is the first give away ;) Don't assume that these kernels do the same
things as stock kernels - usually, they have enough differences to make
things strange. IDE especially - UDMA is a good example. Although, in this
case, it probably doesn't make any difference....

Try checking the errata. RAID is always breaking; IIRC 2.2.16 is no
exception. It'll probably be a one-line patch or something, if there is one,
but it would be enough to snap a RAID config.

mke2fs /dev/hda(whatever) .. etc.? There are many, many ways to nuke
partitions...

Heh ;) I think you're poking the UNIX demon in the eye with a big stick
trying to run software RAID0; it's never as easy as that. You're exchanging
performance for reliability, and once you've sold your reliability to
UNIX-satan you're destined to have problems ;) Don't make pacts with devils.

Cheers,

Alex.
