> The existing 
> [VolumeManager|https://github.com/apache/mesos/blob/1.10.0/src/csi/volume_manager.hpp#L55:L138]
>  is like a wrapper for various CSI gRPC calls, we could consider leveraging 
> it to call CSI plugins rather than making raw CSI gRPC calls in `volume/csi` 
> isolator. But there is a problem, the lifecycle of the volumes managed by 
> VolumeManager starts from the 
> `[createVolume|https://github.com/apache/mesos/blob/1.10.0/src/csi/v1_volume_manager.cpp#L281:L329]`
>  CSI call, but what we plan to support in MVP is pre-provisioned volumes, so 
> we need to refactor VolumeManager by making it support pre-provisioned 
> volumes.
