Actually fibmap is only working on regular files. (So the directories
are just
counted for fun.) Hardlinks are treated as regular files, symlinks are
not followed.
But you say, xfs_db frag found a fragment value of 0.02 % that is 0.9998
in my way of counting
which is rounded to 1.000. I changed fibmaps final output to show 6
digits.
Please, give it another try
