Yes, sorry, there are two different problems here. The one I was
talking about happens when you go above 16TB. That fix is easy.
Going to a fs size a little greater than 1TB is triggering another

to use for the new file system --- and we have the appropriate tests in
that code path.
But if the user specifies the size explicitly, we aren't checking to
