Hi people

I do df -h on my machine and got this RARE ouput

%df -h

Filesystem     Size    Used   Avail Capacity  Mounted on
/dev/ad0s1a    7.7G    2.2G    4.9G    31%    /
devfs          1.0K    1.0K      0B   100%    /dev
/dev/ad0s1d     65G    9.5G     50G    16%    /usr/home

%df
Filesystem  1K-blocks    Used    Avail Capacity  Mounted on
/dev/ad0s1a   8122126 2328406  5143950    31%    /
devfs               1       1        0   100%    /dev
/dev/ad0s1d  68372608 9940308 52962492    16%    /usr/home

50G+9.5G=60.5G   but the partition size is 65G ... where are my ~5G,?
What can i do?

Accept it :-) Or change the minimum free space on the drive. Here's the relevant part of the tunefs manpage:


-m minfree
         Specify the percentage of space held back from normal users; the
minimum free space threshold.  The default value used is 8%.  This value
can be set to zero, however up to a factor of three in throughput will
be lost over the performance obtained at a 10% threshold.  Settings of
5% and less force space optimization to always be used which will
greatly increase the overhead for file writes.  Note that if the value
is raised above the current usage level, users will be unable to
allocate files until enough files have been deleted to get under the
higher threshold.


I haven't checked, but I suspect the FAQ and Handbook at www.freebsd.org have more information on this...
