In this video we continued writing the CSI plugin that we have been writing in previous videos in this series and implemented the NodeGetCapabilities and NodeStageVolume RPCs of the node plugin.
This RPC (NodeStageVolume) is called after the ControllerPublishVolume of the controller plugin was successful and Node plugin has specified that is supports stage and unstage of volumes (using NodeGetCapabilities RPC).
