Failed to query for metadata size¶
You must pull the MMT image to both your 2.9.x system and your 3.0.x system, otherwise the migration will fail with the following error message:
Failed to query RethinkDB for total metadata size: failed to convert query response to int: strconv.Atoi: parsing "": invalid syntax Continuing without total metadata size ...
To remedy this you must pull the MMT image to each of the two systems, using the following commands:
docker login registry.mirantis.com -u <username> docker pull registry.mirantis.com/msr/mmt
