Hm, I should said do compare but do NOT send this to list
(it contains volume key).

You should reencrypt your devices now...
(including truecrypt device you have mapped, because they are no longer
secure)

That's fine, it should be LUKS device without partition
(this message is misleading and should be removed from kernel IMO)

I thihk LUKS/dmcrypt  works as expected here, something was corrupted in MD or ext4.

check plain (unlocked) luks device as well, maybe you will see some pattern
which explains that why overwritten (it apparently missing ext4 or any known signature
to blkid)
