CRD Upgrade Validation

During the upgrade process, the Custom Resource Definition (CRD) may be applied after the new Longhorn manager has started. This sequencing ensures that the controller does not process objects with deprecated data or fields. However, this can result in the Longhorn manager failing during the initial upgrade phase if the CRD has not been applied yet.

If the Longhorn manager crashes during the upgrade, check the logs to determine if the failure is due to the CRD not being applied. In such cases, the logs may contain error messages similar to the following:
