Tested with F4-220. This a direct port of the Xpenology fancontrol script by Eudean to work on OMV/Debian.

1. Clone the repo git clone https://github.com/ahmedmagdiosman/terramaster-fancontrol.git

2. Build with GCC. I'm using the docker image for ease of use.

   • Pull the image:

docker pull gcc

• Compile fancontrol.cpp (you must be in the same directory)

docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp gcc gcc -o fancontrol fancontrol.cpp

3. Create a directory containing all the drives. I created a directory in /opt/disks/ and just empty files inside (as root):

mkdir /opt/disks
cd /opt/disks
touch sda sdb sdc

This far from perfect and if you're a Linux wizard you probably can do something better with regex, e.g. /dev/sd*[a-z]

4. Run the compiled program (command descriptions in the author's thread).

sudo ./fancontrol 1 40

This will run it in debug mode (1) with temperature setpoint= 40c. Make sure run with fancontrol with sudo.

5. Alternatively you can use the included systemd service. Copy it to /etc/systemd/system. Also, copy the binary to /usr/local/bin/fancontrol.

sudo systemctl start fancontrol.service
sudo systemctl enable fancontrol.service
