mdgm might have some ideas on how to fix your mount options, it doesn't to like the 16384 block size.
But it can't read the data from the parity disk, which is a problem if the Duo failure corrupted the data disk somehow. The raid recovery software in my earlier link might work with the parity disk - if the eval sees the data, you'd need to purchase the software I think.
Netgear also offers recovery services - you pay up front, with no guarantee of success.
Your last option is to get a used duo v1 or nv+ from somewhere, and install the disks in it. We have seen some reports here of people selling broken NAS, so there is some risk there too.
The freeware Linux Reader package (http://www.diskinternals.com/linux-reader/) can access the first [data] disk if you can connect the disk to a Windows system.

Newer models use distributed parity.
