 |
|
Hi. I'm using cpudyn to keep things lo-pro while my computer is idle (which it is a lot). One of the 2 things this does is spin down the disks after a period of innactivity. I gather the same thing can be accomplished with hdparm, but I figured since I'm running cpudyn anyways may as well not fidget with hdparm init scripts. I've got 2 disks, one for gentoo and one for xp. Neither os mounts the other one's disk, so when I'm in gentoo, hda (xp) sleeps and stays asleep til I boot to windows or poke it with hdparm.
So I know that something (either cpudyn or the default power management settings) is doing its job on hda. hdb (gentoo) on the other hand will go to sleep if I hit it with hdparm -y, but it wakes up again after about a minute. It never sleeps if I just leave it alone. So I figure I've got a process that's keeping it active. What could it be? I'm very bare bones and have no loggers or cron daemons. Here's my ps aux :

most of that stuff is kde related. Other notable jobs are nfsd and sshd and X. Thats about it. Like I said, there's no loggers or cron daemons to poke the hd, so what could be accessing it? KDE seems like a likely suspect. Anyone familiar enough with the KDE system to know what could be accessing the HD so regularly and how to stop it?

* If you are near your physical RAM limit, swapping to disk will occur
* Even if you aren't, Linux likes to keep RAM free for responsiveness. You can tune this behavior with the "laptop_mode" and "swappiness" switches in /proc/sys/vm
How I do it on my laptop, to save power while on battery:
| Code: | echo 1 > /proc/sys/vm/laptop_mode
echo 20 > /proc/sys/vm/swappiness
hdparm -S1 -B1 -a16484 /dev/hda |
I then reverse with the following:
| Code: | echo 0 > /proc/sys/vm/laptop_mode
echo 60 > /proc/sys/vm/swappiness
hdparm -S0 -B235 -a256 /dev/hda |
Please check the hdparm switches for yourself! Good luck

Journalling filesystems (ext3 =, reiserfs, etc) regularly dump journal ocntents to disk (5 sec for ext3 I think).

laptop_mode handles this

tells you what's avaliable. I have "vm.swappiness" with kernel 2.6.7.

@ Hypnos:
hmm, i think i read somewhere that the later 2.6 kernels have something like an auto-swappiness inside the kernel which replaces the manual one and thus is not available anymore... not sure tho |
