    df command percentage error


    Hi.
    With root...
    Code:
    # df -h
    Filesystem                      Size  Used Avail Use% Mounted on
    /dev/mapper/VolGroup00-Backups  425G  377G   27G  94% /Backups
    Look carefully the result of my "df" command...
    Size = 425G
    Used = 377G
    Available = 27G
    Used + Available = 404G != 425G

    ¿Why is Used + Available different from Total Size? This is not happening in any other server.
    I've tried remounting and rebooting the system.
    The "du" command show that the "Used" space in the "/Backups" directory from the "df" command is correct!


    Details:
    * Slackware 13.37.0
    * Linux 2.6.37.6-smp #1 SMP Sat Apr 9 14:01:14 CDT 2011 i686 Intel(R) Xeon(R) CPU E5530 2.40GHz GenuineIntel GNU/Linux
    * HP DL360 G6

    Thanks in advance.
    Bye!

    because the filesystem itself takes up some of the space that is not reported by df. If you format a 1TB hard drive as EXT4 you lose a bit of the space to the EXT4 format (it's worse in NTFS but every format will use some space immediately)
