Hi,

I just build my NAS and the first problem came up.
I'm using 2x WD Red 3TB drives, they are recognized by Greyhole and everything works fine.
However, i can't spin them down. They are constantly running, which isn't really good.

I already tried shuting them down by:

Code: Select all

nas@NAS:~$ sudo hdparm -y /dev/sdb
/dev/sdb:
 issuing standby command

nas@NAS:~$ sudo hdparm -C /dev/sdb
/dev/sdb:
 drive state is:  active/idle

There is a short "squek" and the drive is running again/still running.
Apparently, the problem is hddtemp, which is the only process, accessing the disk:

Code: Select all

nas@NAS:~$ sudo lsof /dev/sdb
lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/nas/.gvfs
      Output information may be incomplete.
COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
hddtemp 1337 root    4r   BLK   8,16      0t0 7400 /dev/sdb

nas@NAS:~$ sudo kill 1337
nas@NAS:~$ sudo lsof /dev/sdb
lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/nas/.gvfs
      Output information may be incomplete.

But killing hddtemp doesn't help. Putting them into standby via hdparm still doesn't work.

Does anybody know, what to do?
Thanks

Search these forums as I have seen this topic before. There should be some guidance there.

I've set my disks to spin down after 21 minutes (APM level 252) but I can see that hddtemp is used on them. Did you find a solution to this?

Spinning media is still king for large storage, unfortunately, they are noisy in a small flat:P

My /dev/sda on which amahi is installed is a quiet SSD.

Not sure if this will help, but this was something I documented from a past user.

Code: Select all

#power drives down after 10 minutes idle
/sbin/hdparm -S120 /dev/sda
/sbin/hdparm -S120 /dev/sdb
