Add the following entry to your /etc/hosts file:
127.0.0.1 localhost
Disabling Automatic Updates
sudo systemctl stop update-engine locksmithd sudo systemctl disable update-engine locksmithd sudo systemctl mask update-engine locksmithd
Freeing Up Space
To find large files:
sudo du / -h | grep "^[0-9\.]\+G"
Mounting a Volume as a Service
To automatically remount a volume after your node restarts, create a file like this:
core@etk2017-backup ~ $ cat /etc/systemd/system/ndslabs.mount [Unit] Description=Mount /dev/vdc on /ndslabs After=local-fs.target [Mount] What=/dev/vdc Where=/ndslabs Type=ext4 Options=noatime [Install] WantedBy=multi-user.target
A second example:
core@etk2017-backup ~ $ sudo cat /etc/systemd/system/var-lib-docker.mount [Unit] Description=Mount /dev/vdb on /var/lib/docker After=local-fs.target [Mount] What=/dev/vdb Where=/var/lib/docker Type=ext4 Options=noatime [Install] WantedBy=multi-user.target
Then, you need to run the following three commands on each of your mounts:
sudo systemctl unmask var-lib-docker.mount ndslabs.mount sudo systemctl enable var-lib-docker.mount ndslabs.mount sudo systemctl start var-lib-docker.mount ndslabs.mount
