I'd like to to put the hard drives in standby mode during periods of no activity. I'm just running a file server plus a couple small things on a Qube 3 from home, although the web stuff will increase it's still minimal.
On my NetBSD systems I can use atactl to do this via:
mount -u -o async,noatime,nodevmtime / mount -u -o async,noatime /usr atactl wd0 setidle 5
[wait a time] # atactl wd0 checkpower Current power status: Standby mode
I looked at smartctl but it doesn't look like I can set idle time with it, just readout status and perform self-tests. Is there a way?
Thanks!

if it's some IDE drive then hdparm(8) might help:

hdparm -y /dev/hdd
hmm.. still doesn't seem to stick:
--- root@qube3 /]# hdparm -y /dev/hda
/dev/hda: issuing standby command [root@qube3 /]# hdparm -C /dev/hda
/dev/hda: drive state is: active/idle [root@qube3 /]#
--- I see similar results when setting the spindown time with -S.
Recently run commands should be memory-resident, right? Or do I need to set something somewhere for that to happen? (I'm not activating the drive again just to run hdparm am I?)
I don't see any cron events that are set for every minute or anything super short.
Do I need to set specific mount options? If so, which ones?
Thanks-
Brian

You may have opened files being continuously written to (syslog, audit, sar, ...). chkconfig(8)/losf(8) might tell you if any daemons/programs are involved.
