Set hard drive spin down time

 

Use lsblk to see disks and partitions

You will get something like:

Check status of sdb and sdc

sudo hdparm -C /dev/sd[bc]


Set SDB to spin down after 10 min: Not working for WD Purple

sudo hdparm -S 120 /dev/sdb


(-S 120 is standby at 120*5 seconds == 600 seconds == 10 minutes)

 

 Use hdparm configuration

/etc/hdparm.conf


What works:


Manually putting the drive in standby mode:

hdparm -y /dev/sd[bc]


WD Purple possibly doesn't work with hdparm -S or -B

 

hd-idle is an alternative

Run docker as non-root user

  After creating the docker group and adding my user to it with sudo groupadd docker sudo usermod -aG docker $USER ... I still had to give the /var/run/docker.sock socket and /var/run/docker directory the proper permissions to make it work: sudo chown root:docker /var/run/docker.sock sudo chown -R root:docker /var/run/docker Logout and login again (with that user) then you'll be able to run docker commands without sudo : docker run hello-world   In case of: docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/create": dial unix /var/run/docker.sock: connect: permission denied  run: sudo chmod 666 /var/run/docker.sock
