Seagate Barracuda :-( Not suitable as a raid drive.
Have you read https://raid.wiki.kernel.org/index.php/Timeout_Mismatch
If you're not running that timeout script you are, unfortunately, a
perfect example of why Barracudas aren't a good idea. If that script
fixes most of your problems (it won't help you retrieve the array, but
it *will* help you keep the array alive while you try to recover your
data off it) then you need to replace all drives with more suitable ones
asap - Ironwolves perhaps?
