what does linux consider `idle` regarding hard disk activity? i`m trying to set hdparm to put to sleep my hd after 30 minutes of inactivity `hdparm -S 241 /dev/hda2`, but the drive simply refuses to.
is it because i have set cron jobs? or is it some of the processes, like kflushd, /sbin/update, or kswapd that keep the hd from resting?
thanks in advance, specially from my hd...
all the commands were executed as root, and the machine is not used as a server or any other type of task, is a humble 486 `monouser`, once i log out nobody uses it. the lilo instruction `no_hlt` is not set.
system info: slackware 4.0.0/linux 2.2.6/486 [Checking 'hlt' instruction... OK.]
