Consult the mount (?) man page for details on the noatime option. What I'm trying to understand is: what's writing files, when the machine is idle?!

Aren't all the logs rotated by daily/weekly cron jobs? There are by default in Debian. But yes, you can just delete them. David Vrabel Nope, not all the logs. ppp-logs are, but not syslog, f.ex. Oh well, someone indicated that I had already done a pretty good job by reducing wake-ups to three times pr hour, so maybe I should leave it. Now if I could only get my nic working...

Potato keeps waking up?!
My apologies if this is a FAQ, but I'm stumped here. System: Compaq Deskpro PII350, 128Mb ram, Potato (upgraded from Slink). Fresh recompiled 2.2.16. Stand-alone box using an ISDN-connection via ppp. The bios has a lot of very nice power-saving facilities, which seem to function fine, but Potato keeps spinning the disk up every 20 minutes just for a very short burst of activity, and then spins down again after a while. I disabled the MARK in the logs (and some other redundant logging), and set cron to only run exim hourly (by which I learned a whole lot and cut the spin-ups by 50%), but I'm still not satisfied; I would like to have the box sleep completely and maybe only spin the drive once every hour or even less often. What puzzles me most is: I just can't figure out what keeps spinning the disk?! I can't find any ref's to it in the logs or in cron-whatever... If necessary I could post some of my log-files?!

I'm suprised you're getting it to spin down for that long even. You should try the noflushd package in woody. It's for exactly this type of situation. -- see shy jo
