System: NetBSD lyra 1.5_ALPHA2 NetBSD 1.5_ALPHA2 (LYRA) #0: Sun Oct 1 11:54:43 CDT 2000 gendalia@solstice.cc.iastate.edu:/usr/src/sys/arch/i386/compile/LYRA i386
>Description:
A filesystem that started out being very close to 85GB has had about 3GB
of files copied to it, then some of the files deleted (files included
pkgsrc, src & xsrc, with object files in the first two, then the object
files in src & pkgsrc were cleaned up).
lyra:/stuff# df -k /stuff
/dev/raid0d 55925583 7655619 47710709 13% /stuff
lyra:/stuff# du -sk .
2392785 .
lyra:/stuff# du -a|wc -l
115295
This is after about 9 hours of lfs_cleanerd running after most changes on
the filesystem had stopped.

>How-To-Repeat:
copy files to a large LFS partition.
>Fix:
Hmm. Give up and go back to FFS and hope the machine never crashes.
