Ok, so we ignore the RAID.

Those will have gotten synced immediately, RAID inconsistencies
live only for as long as they are in the write queue. No hope 
there.

Ok, the LUKS superblock (or what is left of it) will be at
the start of /dev/md2. Can you post the following (will
not compromise your datta, that is protected by the 
passphrase(s)):

  head -c 1k /dev/md2 | hd

This allows a manual look of what is left of the LUKS header.

Regards,
Arno
