is this just rounding error combined with the 1000=1k vs 1024=1k
marketing stuff, or is there some limit I am bumping into here.

This isn't an xfs limit, I've set up several hundred big xfs FS for
more than 5 years (13 to 76 TB) and never saw that. It must be a bug in
df or elsewhere. What distribution is this? and architecture?

debian 5 on amd64.

at this point I'm fairly sure that it's just rounding error combined with the difference between 10^9 and 2^30 definitions of TB
