That's very kind of you but I'm no guru, just a user like yourself, 
though perhaps with a little more experience and I've hung around here a 
while because I like to know what goes on inside the black box.

I don't know if the tune2fs info will be identical but it would be 
similar. You'll need to --create the array again with the corrected 
chunk size, not just --assemble it, but yes this on its own might very 
well be enough to get your filesystem back.
