Firstly, please post plain text attachments - that will cut down the
size of them as well...

Secondly, your raid has completely screwed the filesystem. I would
strongly suggest that you confirm that the rebuild of the RAID put
stuff back together properly (check things like the order of disks
in the stripe, etc). If it claims nothing is wrong, then it has been
lying to you.

I hope you have backups, because that's the only way you're going
to recover this mess.
