I burnt my fingers on the heat-sink of the nforce4
north/southbridge/mcp-chip and decided it was too hot ;-)

Filesystem   1K-blocks         Used      Avail Capacity iused     ifree %iused  Mounted on
/dev/da0.eli 10657598008 5464985376 4340004792    56%  139261 335877569    0%   /mnt

Not very many inodes used.

But I rejoiced too early, just as I'm writing this e-mail I started a
python-script and my files were gone again partialy:

radium# cd /mnt/temporary/
radium# cfv *
[output deleted]
radium# ls -1 | wc -l
    311
radium# cd
radium# umount /mnt
radium# mount /dev/da0.eli /mnt
radium# cd /mnt/temporary/
radium# ls -1 | wc -l
    3887

AARGH!
    
And this seems to be rather random behaviour...
