Failure Prior to the Installation of N+1 Load on a SubcloudΒΆ

You may encounter some errors prior to Installation of the N+1 load on a subcloud. This section explains the errors and the steps required to fix these errors.

Errors can occur due to any one of the following:

  • Insufficient disk space on scratch filesystems

  • Missing subcloud install values

  • Invalid license

  • Invalid/corrupted load file

  • The /home/sysadmin directory on the subcloud is too large

If you encounter any of the above errors, follow this procedure to retry the orchestrated upgrade after addressing the cause of failure:


  1. Delete the failed upgrade strategy

    ~(keystone_admin)]$  dcmanager upgrade-strategy delete
  2. Create a new upgrade strategy.

    ~(keystone_admin)]$ dcmanager upgrade-strategy create <<additional options>>


    If only one subcloud fails the upgrade, specify the name of the subcloud in the command.

  3. Apply the new upgrade strategy.

    ~(keystone_admin)]$ dcmanager upgrade-strategy apply
  4. Verify the upgrade strategy status

    ~(keystone_admin)]$ dcmanager strategy-step list
