Funny that you should say that - the md I was putting up was being used 
to migrate data to a larger array, one that is 3.2 TB in size. The 
"temp" md was only 1.8 TB. The issue with the "temp" array was that it 
had to finish resyncing before I could format and move files to it.

FYI, large filesystem support is built into all modern kernels. However, 
  you do need EFI/GPT partition support turned on to mount > 2TB 
kernels, and you need to use parted to create the partitions.

Both arrays are currently functioning just fine right now, thanks for 
everyone's help.
