Change a Worker Host Performance ProfileΒΆ

Changing the performance profile assigned to a worker host is useful for adjusting low-latency resources on a StarlingX system.

Procedure

  1. Lock the host.

    Open the Hosts tab on the Host Inventory page, available from Admin > Platform > Host Inventory in the left-hand pane.

    Select Lock Host from the Edit Host drop-down menu in the Actions column.

    Wait until the host is reported as locked.

  2. Delete the host from the inventory.

    Note

    Ensure that the host is Online so that its disk is erased when it is deleted from the inventory. This ensures that the host boots from the network when it is powered up for re-installation. If the host is not online when it is deleted from the inventory, you may need to force a network boot during re-installation.

    Select Delete Host from the Edit Host drop-down menu in the Actions column.

  3. Reinstall the host and select the desired performance profile.

  4. Assign a node label to the host to enable host selection during Application scheduling.
