FreeNas 9.1.1 - HDD full load for hours

[gatto012]

hi all

i have recently upgrade my nas ( an Atom all-onboard N2800, 4 gb ram, 1 X hdd WD caviar green 2TB )
from 8.3.0 to 9.1.1

fro some days all work good, any problems

Last 2 days, hd start to work continuously, for hours without to stop.
All seems good, Transmission work good, i can transfer and backup all from and into hd, just a bit slow to copy.
The hd have some noise, but isn't the tipical " clip " sound of an hdd near to die... ( system have only one years and some months.... )

What happen? Any ideas?

Are you running ZFS? Is there a scrub in process? Run "zpool status'" from a console prompt.

You should also run smart tests against your disks. I can't type the syntax one my phone.

ps.: i just see that restarting NAS, hdd stop work while restarting/boot, and start again work just when FreeNas again load....

short/long smart tests can' be completed, try some times, stop at 10% left ( cause, i think, hdd never offline from i have this issue )

ty so much for help and infos!

Reading the guide about scrubs scan, is see that:

If you have consumer-quality drives, consider a weekly scrubbing schedule. If you have datacenter-quality drives, consider a monthly scrubbing schedule.

I have a HDD WD caviar green, should be good change/reduce the days interval?

Twice a month would probably be fine.

Since you're using a WD green drive, did you run the wdidle (DOS) command against it, and change the autopark timer on it? If not, you might encounter high Load_Cycle_Count's and wear out the drive prematurely. I believe it's rate for 300k over the life of the drive.

Syntax for checking your disk, might be something like this: smartctl -a -q noserial /dev/adaX

doing

smartctl -a -q noserial /dev/adaX

i don't remember so well, but i think it's the version without IntelliPower ( btw, i disabled any power maner for hdds from settingd of FreeNas )
