    Continuous Hard Disk Activity-files touched every 2 seconds.


    Ever since I installed SuSE 9.1, my hard drive light flashes once every 2 seconds or so. The find utility reports that there are around 1000+ files whose modification time falls within the minute. Almost all these files are 0 bytes so I'm not sure what this really means. Perhaps they are just being "touched". There are some (about 2 dozen) non-empty files that show up as being modified - most of them in /proc or proc/bus/pci or in /dev. Note that these are files that are supposedly being modified (not just accessed).

    I find this a bit unnerving. I only use the system for personal work, and going on the internet, so this kind of activity seems rather gratuitous. Can anyone shed some light on this.

    Having looked up some possible explanations for on the web, I tried using the noatime option in etc/fstab but that does not change anything. In any case as I mentioned, the files are modified - not merely accessed. I also tried powersave setting but that had no efect either. I originally had 128 MB of RAM which I increased to 256. That too made no difference.

    Running top, shows that kdeinit is at the top most of the time. kdeinit has several subprocesses - kio_file, kio_http, artsd etc. Not sure if it has anything to do with this.

    NOTE: When I first installed the system, I had noticed that it was causing problems with my NT installation leading me to disable ACPI. Please have a look at the last two posts (#52 and #53) on THIS page.

    I can think of a few sugestions that might help this..

    1. strip all the cards out of your pc (except display) and turn it on.. if the problem is gone then begin re-insterting the hardware one at a time and testing the os.

    2. remove kde.

    The only cards are sound card and network card. I doubt it is the sound card. Also it is installed as a "stand-alone" system so there are no network services running. I shutdown as many processes as I could from the taskbar and these are the remaining:

    OK, I found the culprit. Liitle beast by the name of suseplugger which lies awake at night worrying about whether you are about to install some new hardware. Turned it off and set it to not startup at boot time. Hard drive is now resting peacefully.

    Is there a configuration file which specify the applications that must start up on boot - just for future reference.

    Now, however, I've noticed another strange problem. The susehelpcenter application takes about 3 minutes to start up.

    Regards,
    SKM.

    Check the manual page for the file /etc/inittab:
    Code:
    %  man inittab
    and see the directories under /etc/rc.d/ . Also try Googling "Linux boot process" or something similar, for example.

    //got nothin'
    ///this use to look better
