Tips and tricks for Debian on QNAP TS-21x/TS-22x

Here are some tips and tricks about running Debian on the QNAP TS-21x/TS-22x.

Automatic fan control

Debian ships a program called qcontrol which can be used to control the fan, LEDs and buttons on QNAP devices. You can edit the /etc/qcontrol.conf configuration file to change the behaviour of qcontrol, for example how the fans are regulated depending on the temperature or which commands to run when a button is pressed.

Scheduled power

You can tell your QNAP device to power on at a specific time using the wakealarm system. For example, if you want your QNAP to power on in 5 minutes, issue the following commands and turn off your device:

echo 0 > /sys/class/rtc/rtc0/wakealarm
echo `date '+%s' -d '+ 5 minutes'` > /sys/class/rtc/rtc0/wakealarm

You can check check whether a wakealarm has been configured with:

cat /proc/driver/rtc

Look for alrm_time and and alrm_date.

Automatic power on

QNAP machines can turn on automatically when power is applied if the device was not powered down correctly. This is helpful when your power goes down. In order to enable this feature, run the following command:

qcontrol --direct autopower on

Disk order on the QNAP TS-219P

One note for Debian users on the TS-219P (this note does not apply to TS-210 and TS-219): when you use the QNAP firmware, the disk on the left is HDD1 whereas the disk on the right is HDD2. However, on Debian it is the other way around (HDD1 is on the right, HDD2 is on the left). This doesn't really matter since Debian uses unique IDs (UUIDs) to refer to partitions, but don't be surprised when the "HDD2" light goes on when you access the first disk.
