How is it possible for a partition to be more than 100% full? # # A portion of each UFS partition (8%, by default) is reserved for use by the # operating system and the root user. df(1) does not count that space when # calculating the Capacity column, so it can exceed 100%. Also, you will # notice that the Blocks column is always greater than the sum of the Used # and Avail columns, usually by a factor of 8%. So, if you take 8% out of 74GB you will get 68GB ( eg. 74*0.92 = 68.08) > > Also, what's the ".snap/" directory for? Probably some snapshot of filesystem state. ////jerry > > Thanks so much! > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" >
