I'm trying to build a raid array (preferrably RAID5, but 0 will do) on a
Sparc platform. I've been 98% unsuccessful in doing so. I've been
successful in getting a raid 0 array built under 2.2.1, but as soon as I
shut it down, it destroys itself, and is unrecoverable. Also 2.2.1 appears
to be terribly buggy in the SMP code for sparc, and I can't really use it.

There are no messages sent to console upon failure.
Does anyone out there know the magic wand tricks to make this work, or am I
just a little to early in the development to get something that works yet?
