How are you doing the copy?

Your new filesystem does indeed seem to be about 1G bigger, based on the
xfs_info output.

XFS+NFS uses something called a refcache, which can hold some extra
space for a while.

If you are copying via nfs, try 

echo 0 > /proc/sys/fs/xfs/refcache_size

before you copy, and see what happens.

If not nfs, we'll have to keep thinking about this. :)
