I'm trying to see if my disks will spin down after a period of time. So far no good. Is it possible to see which process is using the disks? Running the script I just get this.

Code:
camcontrol: error sending command
da0: UNKNOWN
ada0: SPINNING
ada1: SPINNING
ada2: SPINNING
ada3: SPINNING

can you put the shell code t the above disk check

So it seems here, that we have determined that we can't spin down idle drives. Too many variables, too many functions/daemons running especially a fully featured nas.
It's safe to say, we can put this one to rest by concluding that the drives will always be spinning. This is why i give my drives a maximum life of 5 years, even though i don't leave my nas on 24 hours a day, it's just the average used in data centres globally.
