This is an FAQ: see
http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/disks.html#DISK-MORE-THAN-FULL
and the -m option of tunefs(8):
http://www.freebsd.org/cgi/man.cgi?query=tunefs&sektion=8
Summary: the filesystem needs "elbow room" to operate under typical
load; this 8% space is reserved. (It may be consumed by the root user,
if required.) Tuning down the reserved percentage is not recommended
unless you know what you're doing (that is: benchmark your typical
usage to see if the performance is still within acceptable limits).
