Sorry, I didn't realize that you weren't able to find *any* backup
super blocks. In that case, either you got really unlucky and you had
some failure which has taken out a very large number of blocks, spread
out across the file system --- or I'd have to agree with Eric, I'd
want to be really, really sure that the Raid array hadn't gotten
assembled incorrectly somehow....
