Shut Down and Reboot Nodes

You may need to shut down or reboot one or more node VMs for reasons such as performing a scheduled maintenance activity, upgrading your ESXi server, recovering from a node failure, and so on. This topic describes how to gracefully shut down and restart your node VMs.

Shut down a node VM

  1. Log in to the node VM. You are placed in Paragon Shell.

  2. Type exit to exit to the Linux root shell.

  3. (Optional) Check the health of your cluster. Execute the # health-check command from the Linux root shell. The Overall Cluster Status ideally must be GREEN.

  4. Shut down the node using the # shutdown -h now command.

    Note:

    If you are shutting down all your nodes, you must shut down all the VMs around the same time. We recommend that the time taken to execute the shutdown -h now command on all the four VMs does not exceed ~120 seconds. The VMs might take longer to actually shutdown but you must execute the command on all the four VMs within that period.

Reboot a node VM

  1. Log in to the node VM. You are placed in Paragon Shell.

  2. Type exit to exit to the Linux root shell.

  3. Reboot the node using the # shutdown -r now command.

  4. (Optional) After the VM has rebooted, verify that the cluster is in good health. Execute the # health-check command from the Linux root shell. The Overall Cluster Status must be GREEN.
