Can I put my RAID5 to sleep on Ubuntu?

You can use smartctl to set the sleep timeout per-drive.

You can use hdparm to set power management on the virtual drive. After that it would probably be up to the controller for what it's going to do with the power management commands.

Here is the man page for hdparm: http://linux.die.net/man/8/hdparm
The relevant options you will want to use will probably be -S and -B.

edit: oops, just realized you are using software RAID. In that case set each drive and there shouldn't be a problem.

Er yea, I meant hdparm, not smartctl :-/

Well, I was wondering, but I thought "well, maybe smart does more than I realize"

Beyond making the discs sleep, you might even just set the whole box to go to sleep or power off
during off-hours or whatever. You can use real time clock alarm wake-up or wake-on-lan to wake it up
or soft-power it on whenever desired.
