How to safely shut down the OS​

To prevent data corruption, you should always safely shut down the OS before unplugging power from your machine.

via Machine Administration​

  1. Open the browser app for Machine Administration.
  2. Click on the "Shut down" button.
  3. Wait at least 30 seconds before unplugging power from your machine.

via Cockpit​

  1. Open Cockpit
  2. Click on the dropdown menu attached to the "Reboot" button in the upper-right area of the page.
  3. In the dropdown menu, click on the "Shutdown" menu item.
  4. In the modal dialog which opens, select a desired delay for the machine to wait before shutting down, and then click on the "Shut down" button.
  5. Wait for the delay to elapse; Cockpit should display a message indicating that its server connection has been closed.
  6. Afterwards, wait at least 30 seconds before unplugging power from your machine.

via the terminal​

  1. Enter the machine's terminal.
  2. Run the following command: 
    sudo systemctl poweroff
  3. Wait at least 30 seconds before unplugging power from your machine.

How to soft-reboot the OS​

Many kinds of OS configuration changes (such as those done in OS updates) require the machine to be rebooted before the changes take effect. Such changes can be applied with a soft reboot, which is significantly faster than a full reboot because a soft reboot restarts all system services but does not restart the OS's kernel, computer firmware, or computer hardware.

via Machine Administration​

  1. Open the browser app for Machine Administration.
  2. Click on the "Soft reboot" button.
  3. Wait until your computer is able to re-establish its network connection to the openUC2 OS machine; depending on your network configuration, you may need to take manual action to re-establish the network connection.

via the terminal​

  1. Enter the machine's terminal.
  2. Run the following command: 
    sudo systemctl soft-reboot
  3. Wait until your computer is able to re-establish its network connection to the openUC2 OS machine; depending on your network configuration, you may need to take manual action to re-establish the network connection.

How to fully reboot the OS​

You may occasionally need to fully reboot the OS, for example when troubleshooting unexpected behavior in the OS.

  1. Open the browser app for Machine Administration.
  2. Click on the "Full reboot" button.
  3. Wait until your computer is able to re-establish its network connection to the openUC2 OS machine; depending on your network configuration, you may need to take manual action to re-establish the network connection.
