Select a bootable device for a node¶

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
     volumes:
       - keep_data: false
     

     Note

     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
