I'm fully with you on -o inode64, but I would think it is not inode number
that becomes large with extensive use of hard links, but the space used by
directory data, thus requiring to relocate these once they exceed some
size so ultimately some of them will be pushed beyond 1 TB border
(depending on how the filesystem is used). Someone, correct me if I'm
wrong.
