Synopsis: df -h displays wrong values using FreeBSD 4.10 with Promise ATA RAID Fasttrack TX 2 State-Changed-From-To: open->closed State-Changed-By: le State-Changed-When: Fri Nov 19 21:55:34 GMT 2004 State-Changed-Why: That's normal behaviour. The UFS filesystem reserves a certain amount of space called the 'minimum free space treshold'. This free space is used to optimize write performance on the filesystem and to avoid fragmentation. The default value is 8% of the filesystem size. Have a look at the tunefs(8) man page, especially the -m parameter, for how to change this treshold value. http://www.freebsd.org/cgi/query-pr.cgi?pr=74109
