Step H: Upgrade Node A - AWS Elemental Delta

This is version 2.3 of the AWS Elemental Delta documentation. This is the latest version. For prior versions, see the Previous Versions section of AWS Elemental Delta Documentation.

Step H: Upgrade Node A

The node must be in a working state prior to upgrade. If the node is in a degraded state (for example, the web interface isn't responding), the upgrade fails.

Perform these steps at the hardware unit for node A.

  1. Run the installer with the skip-all option:

    [elemental@hostname ~]$ sudo sh ./elemental_production_delta_<version>.run –-skip-all

    The installer automatically stops the software, if it's still running. The following prompts are skipped:

    • You are not prompted to change the network setup (eth0 and eth1) or the Ethernet partitioning (setup of eth0 as a management interface).

    • You are not prompted to choose the time zone.

    • You are not prompted to enable or disable user authentication.

    You are prompted to accept the EULA (end user license agreement).

    The new software is installed and all services except elemental_se are automatically restarted.

  2. Once installation is complete, you might be prompted to reboot:

    Installation and configuration complete! . . . NOTE: You must reboot your system to finish the installation!

    Enter this command to reboot:

    [elemental@hostname ~]$ sudo reboot

    The reboot takes approximately 5 minutes. When the reboot completes, the elemental _se service automatically starts. Look for this message on the command line:

    Starting elemental_se: [ OK ]

    Node A joins the cluster. Node B is the leader now and node A is the secondary.

  3. If you're not prompted to reboot, you are prompted to start elemental_se:

    Would you like to start the Elemental service now? [Y]

    Enter Y.

    The restart takes approximately 1 minute. When the restart is done, this message appears:

    Installation and configuration complete! Please open a web browser and point it to to get to the web interface. Enjoy!

    Node A joins the cluster. Node B is the leader now and node A is the secondary.

  4. If you're not using a health checker, add the node back to the load balancer.

  5. Refresh your web browser to load the updated AWS Elemental Delta web interface.

    When both node A and node B show as green on the Nodes tab, proceed to the next step (Upgrade Egress Nodes).
