Remaining diskspace confusion - "df" contradicts other info.

    Hi There,

    I wanted to do a mysqldump on a live system and under no circumstances do I
    want to break the system. Therefore being very careful I was checking
    certain things out.

    To my webspace my control panel informs me I have used about 50mb of my
    600mb available. However login in via SSH to run the mysqldump, I done a df
    (with limited understanding of the command) and I got the following:

    Filesystem 1k-blocks Used Available Use% Mounted on
    /dev/sda1 99150 79134 14896 85% /
    /dev/sda2 1007896 865348 91348 91% /usr
    /dev/sda5 4031680 1769432 2057448 47% /var
    /dev/sda6 14939148 13231964 948300 94% /home
    /dev/sda7 14939148 5742964 8437300 41% /home2

    Now this says to me there is not much space in the home dir.
    When I do a pwd the path is
    /home/myusername

    (Note that this is a shared hosting account box)

    Now this leads me to believe that although I should have 550mb of space, the
    home folder is almost full.
    Therefore if I do my mysqldump, I could actually make the machine run out of
    disk space making all kind of nasty things happen.

    At first I was going to ask "Can anyone enlighten me on what I am reading
    wrong, or have I spotted a potential error?"

    But discovering df -h led me to the real sizes. So there is actually 926MB
    remaining and 13G used. However, does this not still seem a little low. If
    other users suddenly maxed out their account we would be running at almost
    full capacity (if not over) and should not files systems stay under 90% on
    UNIX boxes.

    Kind regards

    Dave.
