I've contacted just about everyone that knows a thing about RAID5, but no
one is really able to help me. Anyhow I've read up a lot on RAID5 arrays and
how to properly assemble them. However I've run into a problem with a NAS
system from WD that I just can't seem to figure out.

I have a ¾ disks in the array, 1 went down and is out of commission.  I've
been able to assemble my array through mdadm using --assemble --scan. However
I cannot access the array due to the fact that the array cannot read a
filesystem. Everytime I try to mount I get mount: wrong fs type

 etc. I

know that the FS is an ext3 FS. However I cannot seem to get this
thing going. I was wondering if anyone could point me in the right
direction with this. I can't seem to find anyone that is capable of
solving this. I would appreciate any help. Thanks!

What's the output of 'cat /proc/mdstat' after you assemble the array?
And what exact error (and dmesg output) do you get when trying to mount
it as ext3?

Cheers,
