Select a bootable device for a node

Select a bootable device for a nodeΒΆ

By default, Fuel boots the first disk it detects.

To select a bootable device:

  • Using the Fuel web UI:

    1. Log in to the Fuel web UI.
    2. Click the Nodes tab.
    3. In Disk Configuration, select the required disk as bootable.
  • Using the Fuel CLI:

    1. Log in to the Fuel Master node CLI.

    2. Download the configuration file of the node:

      fuel node --node-id <node_id> --disk --download
    3. In the disks.yaml, set bootable: True for the required node’s disk. For example:

      id: vda
      name: vda
      bootable: True
      size: 50380
        - keep_data: false


      Only one disk can have the bootable: True attribute at the same time. Otherwise, an error will occur on the settings upload.

    4. Upload the changes:

      fuel node --node-id <node_id> --disk --upload
