You know, I've been watching this thread thinking something was nagging 
me about this.  And after a night of not thinking about it I remember 
what it was.  I had a similar issue last summer.  The way I fixed it was 
to use LVM.  Create a volume group the size you want and create the 
filesystem inside it.  My volume was only slightly larger than 8TB, but 
it did create and it works great.
