I am using wallaby / trove on ubuntu 20.04. I am trying to extend volume of database instance. Its having trouble that instance cannot exceed volume size of 10GB.

My flavor has 2vcpus 4GB RAM and 10GB disk. I created a database instance with 5GB database size and mysql datastore. The deployment has created 10GB root and 5GB /var/lib/mysql. I have tried to extend volume to 11GB, it failed with error that "Volume 'size' cannot exceed maximum of 10 GB, 11 cannot be accepted". 

I want to keep root disk size to 10GB and only want to extend /var/lib/mysql keeping the same flavor. Is it possible or should I need to upgrade flavor as well ?
