I don't know how, but somehow something is holding references to the removed files causing them to fail to be reclaimed. Could you run your system for a while to build up a new set of these files, then run a script with the `df -ih' as before. Then run `vmstat -m', `sysctl debug', and fstat -f /usr' both before and after doing the umount/mount. Hopefully that will give us some more clues as to what is happening. And Jeff, if you have any ideas do speak up :-) Kirk McKusick
