Ok, I am wondering some about this as I have:
Filesystem               1024-blocks      Used     Avail Capacity iused     ifree %iused  Mounted on
/dev/ada0s2h               473659989 417657089  18110101    96%  918794  47949908    2%   /mnt

And have had that file system for at least a decade,
and it gets dump | restore on a fairly regular basis.
