    sudo find /proc/*/fd -type f -links 0 \! -empty -ls
    Another possibility, albeit quite improbable, is that some big files lurk at the /home mountpoint hidden by mount. Try to unmount /home and see if there's something in there.

    Well, I guess you can free up /usr only by uninstalling some packages. Besides, 6G doesn't look like too much to me.
    Now, thats is strange. I booted from USB disk, mounted my root partition and df -h shows 7.4GB used on /dev/sda5 (which is my root partition) out of 18GB, that is 11GB free. This is even 400MB less then diskspace analyser shows.

    And: there is nothing in the /home mountpoint, i.e. no overlay mount.

    I found a quite extensive thread on http://serverfault.com/questions/570...-df-difference but nothing there helps me.

    Ok, that is strange. After booting from USB and rebooting the problem has disappeard. Note that I could not run fsck since it seems to require ext partition format, while I am using xfs.

    I have a suspicion that the filesystem filled up because of the emulated 512kB logical sector size on 4096kB physical sectors on the new DELL harddisks. I will continue on this thread when this reoccurs.

    Thanks for patience and help.

    There might be a clue in this http://www.postgresql.org/message-id...ilentmedia.com I know its talking about databases but theres a hint in there about xfs preallocation
    I muddled sometimes get my words up
