Ah...THAT's the piece of information I was missing!  Now that you
mention it, I remember reading about that somewhere.  I guess it just
didn't click.

Based on what I've gathered so far, that chart is showing inodes,
metadata, and data as a number of blocks, right?  So to get disk usage,
I add up the used inode, metadata, and data blocks and multiply by block
size (4K)?

That seems to show me a 1.1TB total with 10.5GB used, which sounds about
right.
