Are the 2 disks completely failed? Or just dropped from the array?
Can you provide mdadm -E output from all devices that were in the array?

Do you know what version of kernel and mdadm was used to create the raid5 in
the first place? You should go back to that (at least the mdadm version) and
try the --create --assume-clean with that mdadm version. Several key factors
have changed between versions.

I would not do a --create --assume-clean on your array until you have
exhausted all other options. At 40TB this sounds like a very large
array. With raid5 disk ordering among other things is VERY important.

Look at this thread for a person with similar problem
<http://www.spinics.net/lists/raid/msg41732.html>, there is discussion about
data offset etc in there, might be a good start.
