Supporting 1TB per filesystem means: "is known to work". Being able to 
mount a 2TB FS does not mean anything about if it will work or not once 
you have data > 1TB on it. That's how I understand Arjan's statement.

Up to now, I've always split "big" storage space into chunks < 1TB, 
simply to not run into some of those "border" issues and I had no 
problems with that so far (using ext2 and ext3).
