Chapter 26. Troubleshooting upgrade issues

If you experience any issues with during the upgrade process, refer to the advice in this section.

26.1. Correcting environment files

If you have made a mistake with any parameters in any custom environment files, you can correct the environment file and run the openstack overcloud upgrade prepare command at any time during the upgrade. This command uploads a new version of your overcloud plan to director, which will generate a new set of config-download playbooks.

This example contains a repository name mistake in the upgrades-environment.yaml file: 

parameter_defaults:
  UpgradeLeappEnabled: true
  UpgradeLeappCommandOptions: "--enablerepo rhel-7-for-x86_64-baseos-eus-rpms --enablerepo rhel-8-for-x86_64-appstream-eus-rpms --enablerepo fast-datapath-for-rhel-8-x86_64-rpms"
  CephAnsibleRepo: rhceph-4-tools-for-rhel-8-x86_64-rpms

This mistake causes an issue during the Leapp upgrade for the Controller node. To rectify this issue, correct the mistake and run the openstack overcloud upgrade prepare command.

Procedure

  1. Correct the mistake in the file: 

    parameter_defaults:
  UpgradeLeappEnabled: true
  UpgradeLeappCommandOptions: "--enablerepo rhel-8-for-x86_64-baseos-eus-rpms --enablerepo rhel-8-for-x86_64-appstream-eus-rpms --enablerepo fast-datapath-for-rhel-8-x86_64-rpms"
  CephAnsibleRepo: rhceph-4-tools-for-rhel-8-x86_64-rpms

  2. Run the upgrade preparation command with the corrected file: 

    $ openstack overcloud upgrade prepare \
    --stack STACK NAME \
    --templates \
    -e ENVIRONMENT FILE
    …​
    -e /home/stack/templates/upgrades-environment.yaml \
    …​

    Wait until the overcloud stack update completes.

  3. Continue with the upgrade operation step that failed.
