Now 180M is nowhere near 11G!  Am I reading something wrong?  Why
am I getting different numbers?

Add the space used by the inode blocks.  File/directory data is
stuffed into the inode block if it's under around 3500 bytes.

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.


yes.

Also, to answer one of your earlier questions, metadata is file-system specific data (directories, indirect blocks, etc).
