Opsætning af diske

!!! Er muligvis ikke nødvendigt !!!

Få en liste med disk UUID's

sudo blkid

Disable intern APM (f. eks. WD Green diske).
Hvor a erstattes med det aktuelle device.

sudo hdparm -B 255 /dev/sda

Manuel spindown

sudo hdparm -y /dev/sda

Redigér /etc/hdparm.conf og tilføj

sudo nano /etc/hdparm.conf

/dev/sda {
          apm = 255
          poweron_standby = off
          keep_features_over_reset = on}

Spindown installering

Først installeres build essentials

sudo apt-get install make g++ build-essential

Spindown hentes og installeres.

wget https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/spindown/spindown-0.4.0.tar.gz 
tar xvzf spindown-0.4.0.tar.gz
cd spindown-0.4.0/
sudo make
sudo make install

Kopiér eksempel configuration til etc biblioteket.

sudo cp spindown.conf.example /etc/spindown.conf

Få en liste over disk ID's.

ls -l /dev/disk/by-id/

eksempel:

lrwxrwxrwx 1 root root  9 2012-02-12 16:34 ata-ST940210AS_5QX2B7LY -> ../../sda

Redigér /etc/spindown.conf

sudo nano /etc/spindown.conf

Og tilføj

[Disk 1]
id = ata-ST940210AS_5QX2B7LY
spindown = 1
command = hdparm -y

Standard spindown tid er 1 time (3600 sek.). Denne ændres i /etc/spindown.conf i general sektionen.

idle-time = 3600    # The time in seconds a disk has to be idle before it is spundown.
                    # Do not use a value that is to small (less than 3600) unless you
                    # know what you are doing.

Spindown startes med

sudo service spindown start

Status

Status for diske.

sudo service spindown status

dette giver følgende output med information om hver disk, eksempel.

 * spindown is running
name     watched     active       idle-time        spindown-time
sda            1          1               3                  600

Test om en disk er i standby.

sudo hdparm -C /dev/sda

Hvis dette giver lignende svar

   Loaded: loaded (/etc/init.d/spindown; bad; vendor preset: enabled)
   Active: active (running) since Mon 2016-10-03 17:50:49 CEST; 40s ago

   CGroup: /system.slice/spindown.service
           └─8405 /sbin/spindownd -d -f /var/run/spindown/spindownd.fifo -c /etc/spindown.conf -p /var/run/spindown/spindownd.pid

Kan dette løses ved at ændre '/etc/init.d/spindown'

sudo nano /etc/init.d/spindown

Hvor 'status' ændres til 'status2'

        log_end_msg $?

        exit $?
        ;;

    "status")
        if status_of_proc -p $PIDFILE $DAEMON spindown; then
            echo -n
        else
            exit 1
        fi

ændres til

        log_end_msg $?

        exit $?
        ;;

    "status2")
        if status_of_proc -p $PIDFILE $DAEMON spindown; then
            echo -n
        else
            exit 1
        fi

Og så bruges følgende i stedet

sudo service spindown status2
