Is it possible to sleep hard drives in an array? I have a HTPC at home that's on 24x7. It does all my torrenting as well, and is mainly a media server. Can I sleep the drives in my RAID5 array while it's not being used? It's an XFS partition. I have each drive set as hdparm -S240 /dev/sdX But I'm fairly sure they are not spinning down :( Is there some activity mdadm is doing in the background? These things are probably idle 22 hours of the day.
