The controller does not check whether the volume has been created or not and return successful. Which in turn binds the pvc to the pv. The PVC should not bound until corresponding zfs volume has been created. Now controller will check the ZFSVolume CR state to be "Ready" before returning successful. The CSI will retry the CreateVolume request when it will get a error reply and when the ZFS node agent creates the ZFS volume and sets the ZFSVolume CR state to be "Ready", the controller will return success for the CreateVolume Request and then PVC will be bound.
