Berkeley file systems have a "minimum acceptable percentage of file system blocks." If the file system reaches that threshold, only the super-user can allocate blocks. Because of the way in which Berkeley file systems allocate blocks performance suffers considerably if the percentage of free blocks drops too low. See filsys(4) for details. If you still want to change the value, tunefs(1M) will allow you to do so. --bob-- renglish@hpda.hp.com
