  1. Follow-up Strange HD Behavior

    I did the top thing in the monitor and this is what I got. In order to
    capture the data, I had to use ksnapshot, so this gives a bias to the
    results.

    Cpus: 52.8%us, 10.0%sy, 0.0% bum 0.0%udm 35.9%wa, 1.3%hi, 0.0%sum 0.0%st

    %CPU was: 28.2 ksnapshot, 13.9% firefox-bin, 5.2% Xorg, 4.3% metacity,
    3.6% gnome-panel and the rest as noise.

    How do I capture the data without invoking a screen capture program? It
    does skew the results.

    At any rate, the 35.9%wa seems to be the one I don't understand. It has
    been in the mid 90s% when just after boot. This time it took a few
    minutes for the HD trashing to start.

    Is rdiff-backup or some other backup running in the background?


    $ ps aux |grep rdiff-backup

    killall rdiff-backup
