I bought recently a new pc. I installed Lucid and it works perfectly. The only problem I have is the fact that there is a lot of harddisk activity... Can anybody help me with that?

Re: Problem with harddisk activity
"a lot" is pretty subjective -- how does that compare with "too much" and "just right"?
Some thoughts:
- how much memory in the system, did you make a swap partition? http://kubuntuforums.net/forums/inde...opic=3099574.0
- have you tried turning down swappiness in /etc/sysctl? http://rudd-o.com/en/linux-and-free-...ow-to-fix-that
- is your hardware on the list of drives with a head-unloading issue? https://ata.wiki.kernel.org/index.ph...ds_under_Linux
- are you merely observing the initial strigi indexing on a new installation? If so, it will (eventually) finish and then there will be much less, or else you can do like I do and turn it off.
- what processes might be using the hard drive ("top" will show them in order of resource usage)
If you need more information, you'll have to share some details and your own diagnostic results.

Re: Problem with harddisk activity
Every 5 to 10 seconds the light flashes. Using iotop i discovered it is mostly kdeinit4: plasma-desktop [kdeinit] that uses the disk frequently.Originally posted by dibl
I have 2GB of memory in the system and 2 GB swap partition.Some thoughts:

Maybe that will help. I did not yet do that.- have you tried turning down swappiness in /etc/sysctl? http://rudd-o.com/en/linux-and-free-...ow-to-fix-that
Nope. It's a Western Digital WD2500AAKS- is your hardware on the list of drives with a head-unloading issue? https://ata.wiki.kernel.org/index.ph...ds_under_Linux
I've turned both Strigi and Nepomuk off.- are you merely observing the initial strigi indexing on a new installation? If so, it will (eventually) finish and then there will be much less, or else you can do like I do and turn it off.

Re: Problem with harddisk activity
look at the results of top in a terminal. sit a watch for a minute or so - you should see what's popping to the top of the list. if that doesn't do it, install and run powertop if you can't figure it out. should show whats causing the wake-up'sComment

Re: Problem with harddisk activity
I watched it for a minute or so and i see Xorg always on top, Kwin almost the whole time, plasma-desktop and sometimes irqbalance.
According to iotop, jdb2/sda1-8 uses frequently the disk.Comment

Re: Problem with harddisk activity
is jdb java debugger?
If it is java related - try removing openjdk and installing sun-java6 insteadComment

Re: Problem with harddisk activity
I don't think it is. Just because I haven't installed openjdk (nor Java
)

Re: Problem with harddisk activity
by the way, I got the name of it wrong. It's jbd2/sda1-8. Seems to be part of the new ext4 filesystem. Maybe a bug?Comment

Re: Problem with harddisk activity
Ah, well that's entirely different isn't it?
Try adding these options to your mount line in fstab: noatime, nodiratime, relatime
Consider using a different format until ext4 has it's bugs worked out (I prefer reiserfs). I don't use ext4.
Review your log files to see if something is doing excessive continuous logging.
Likely, you're seeing activity from journaling that's normal. If the activy is severe enough to slow things down I'd do something.Comment

Re: Problem with harddisk activity
