Just guessing it is a mdadm bug.
I have a 32-bit 2.6.27.5 machine with mdadm 2.6.7 and mine is showing
an array size of 4.5tb correctly, so 2.6.29 should be just fine.
Check mdadm --version and see what version that you have of that, you
might also mount up the array and do "cat /proc/mdstat" and see what
size the kernel reports.
