Hi,

If I understand correctly the steps were:

- Run DB sync --> Fail
- Run DB purge
- Restart volume services
- See the log error
- Run DB sync --> version proceeds to 117

If that is the case, could you restart the services again now that the
migration has been moved to version 117?

If the cinder-volume service is able to restart please run the online
data migrations with the service running.

Cheers,
Gorka.
