Troubleshooting

If Chef Automate fails to migrate your data to PostgreSQL 13 when running chef-automate post-major-upgrade migrate --data=PG, restore the data:

sudo chef-automate backup restore </path/to/backups/>BACKUP_ID

If you have Air-Gapped bundle which you want to restore to, then use this command:

sudo chef-automate backup restore  --airgap-bundle </path/to/bundle> </path/to/backups/>BACKUP_ID

Reference for Restore methods.

Use the backup ID from the backup you created before starting the upgrade.

If the restore fails even after upgrading the Chef Automate version, follow the steps given below:

  1. Uninstall Chef Automate:

    sudo chef-automate uninstall

  2. Install the last date-based version (20220329091442) using the air-gapped installation process. See the air-gapped installation documentation for more information.

  3. Restore the backup:

    sudo chef-automate backup restore <backup_id>

See the Chef Automate restore documentation for more information.

Note

If you used backup and restore method to migrate data then you will have to remove this file: /hab/svc/deployment-service/var/upgrade_metadata.json. To mock completion of post upgrade checklist items.
