I need to be clearer. Above is the point at which the corrupt table 
message is encountered. I believe the above is the equivalent of your 
method, and hence your method may not work on 9.3-PRE and above. If you 
happen to be able to test this, I'd be curious as to the results.

I'm going to try gmirroring the entire disk and and using BSD labels for 
separate partitions. I think this will have the effect I want, and it's 
worth a test.

A neighbor asked Nasrudin to borrow his donkey. "It is out
on loan," said the Mulla. At that moment the donkey was
heard to bray, somewhere inside the stable. "But I can hear
it bray, in there."

"Whom do you believe," said the Mulla, "me or a donkey?"
