root@localhost:~ $ df /dev/sdb1

/dev/sdb1            1922858352  23247088 1801935664   2% /mnt/external/sdb1

used+available = 1825182752

Size - 1825182752 = 97675600

97675600 / 1825182752 = 5% this is the default reserved space for root user.

That's an interesting point, however I would expect df to tabulate the physical usage, and not to take into account such a reservation. Is there a switch or a different utility that shows the physical available space? –  andyortlieb Feb 24 '11 at 16:08
