The "ker-chunk" every 30 seconds is probably the syncer. There is a patch floating around to create some sysctls to lengthen the syncer interval. If there are no dirty vnodes, the syncer shouldn't touch the disk, though. Personally, I'd rather have the syncer run on schedule, then let the disk just remain quiet if there aren't any dirty vnodes. Every five minutes, cron launches "atrun" to see if any at(1) jobs are pending. This triggers a write to /var/log/cron, which forces the disk to spin up. If you don't care about at jobs, you can comment the atrun line out of /etc/crontab. -- Chris BeHanna Software Engineer (Remove "bogus" before responding.) behanna@bogus.zbzoom.net Turning coffee into software since 1990.
