-----------------------------

             Summary: CREATE operation shouldn't require the client to specify how it should be mounted
                 Key: MESOS-6374
                 URL: https://issues.apache.org/jira/browse/MESOS-6374
             Project: Mesos
          Issue Type: Bug
            Reporter: Yan Xu


Because CREATE doesn't mount it and there is no container. 

Currently in {{Resource}} protobuf [if 'persistence' is set, 'volume' must be set|https://github.com/apache/mesos/blob/af2d406282d8da0ed93eacf997bf8f94aa77b492/include/mesos/v1/mesos.proto#L831-L832], this requires frameworks to specify a {{volume}} field with a dummy {{container_path}} because it's a required field.

The lifecycle management of persistent "volumes" is so different from regular volumes that we should use the {{volume}} field only in the context of tasks/containers. 

We should put everything related to the management of persistent volumes into {{Persistence}} and not require {{volume}} to be set when we are creating/destroying a persistent volume.
