RAID + Hard drive sleep

[Steve Malenfant]

I know I shouldn't probably do this and maybe it can't be done. But since I
don't use my server that often I'd like my drive to sleep a little bit. I
got the 1.5TB array up and running (From another thread) and both drives are
using about 10W more than the laptop drive I had in there. Now this isn't
much but I'm trying to save a little and see if those drive could
sleep/standby.

I believe I've seen this somewhere. But there might be too many logs written
or other stuff going on (cron jobs, etc..). But I can disable some maybe.

Is there any danger of setting the spindown on the hard drive on a MD array?
If I force the drive to go to sleep (hdparm), then it spins back up right
away. Is this caused by the array writing something to disk all the time?

Any help would be appreciated.

Thanks.
