      For quota and volume attribute consistency purposes, it is important that VACs that cluster-admin creates specifies all the properties and customers do not arbitrarily drop fields when creating multiple VACs.

      This can be implemented as a warning in OCP (lets discuss exact mechanism during design).

       

      Example:

      • VAC A has "throughput: 10GB"
      • VAC B has "IOPS: 1024"
      • User changes their PVC from VAC A to VAC B
        • -> the PVC gets IOPS: 1024, but it also keeps throughput 10GB.
        • -> we should warn VAC authors that "A" misses "IOPS" and B misses "throughput" parameters.
