Beyond my knowledge... Wish I was you! :)

But, if the device has a bug like "bit 33 lopped off".
If he splits the array into 2 luns/devices then it may be fine.
Then create the RAID0 with them.

The standards are very explicit about what READ CAPACITY(10) should
return for a >2TB device. sd detects this and retries with a READ
CAPACITY(16).

There is no message in the log indicating this happened, so I think the
device reported an incorrect size to READ CAPACITY(10). It may have
reported its size with bit 33 lopped off, but that's still a device
problem.
