snapshot, this field will be filled with the "ready_to_use" value

it, otherwise, this field will be set to "True". If not specified,
it means the readiness of a snapshot is unknown.

returned from CSI "CreateSnapshot" gRPC call. For a pre-existing
snapshot, this field will be filled with the "size_bytes" value
returned from the CSI "ListSnapshots" gRPC call if the driver supports
it. When restoring a volume from this snapshot, the size of the
volume MUST NOT be smaller than the restoreSize if it is specified,
otherwise the restoration will fail. If not specified, it indicates
that the size is unknown.

description: deletionPolicy determines whether this VolumeSnapshotContent and its physical snapshot on the underlying storage system should be deleted when its bound VolumeSnapshot is deleted. Supported values are "Retain" and "Delete". "Retain" means that the VolumeSnapshotContent and its physical snapshot on underlying storage system are kept. "Delete" means that the VolumeSnapshotContent and its physical snapshot on underlying storage system are deleted. For dynamically provisioned snapshots, this field will automatically be filled in by the CSI snapshotter sidecar with the "DeletionPolicy" field defined in the corresponding VolumeSnapshotClass.

volumeSnapshotRef:
description: volumeSnapshotRef specifies the VolumeSnapshot object to which this VolumeSnapshotContent object is bound. VolumeSnapshot.Spec.VolumeSnapshotContentName field must reference to this VolumeSnapshotContent's name for the bidirectional binding to be valid.
