I have 7 hard drives that are in a virtual pool (mhddfs) so they appear as one directory. I put them to sleep after 5 minutes of inactivity to save a significant chunk of power.
The problem with this is that it takes quite a while to spin 7 drives one by one down, not to mention the wear and power usage that occurs. I would like to cache the file and directory list so that only when a file is actually requested for access, does the drive spin up.
Is this possible?
