Not so much a question as a note that (if confirmed by others) could be incorporated into documentation?
During restart of VDP services after migration to external metadatabase the container reported below error [20220815 version].
I think the issue is that the conf directory is persisted using PVC, and since these are mounted as root (possibly with Denodo as group using .securityContext.fsGroup:999) it fails.
I resolved the issue by temporarily running the container in root mode (not recommended), by adding this to yaml
spec.template.spec.securityContext.runAsUser:0
