Create VolumeSnapshotClass

A VolumeSnapshot is a snapshot of an existing PV on the storage system, and each VolumeSnapshot is bound to a SnapshotClass that describes the class of snapshots when provisioning a VolumeSnapshot.

To create a VolumeSnaphotClass, refer to the following:

Field	Description	Value
driver	The driver that determines what CSI volume plugin is used for provisioning VolumeSnapshots.	com.iomesh.csi-driver
deletionPolicy	Allows you to configure what happens to the VolumeSnapshotContent when the VolumeSnapshot object is to be deleted.	Delete

Procedure

1. Create a YAML config snc.yaml and configure the fields driver and deletionPolicy.

   # Source: snc.yaml
   apiVersion: snapshot.storage.k8s.io/v1
   kind: VolumeSnapshotClass
   metadata:
     name: iomesh-csi-driver
   driver: com.iomesh.csi-driver  # The driver in iomesh.yaml.
   deletionPolicy: Delete # "Delete" is recommended.
   

2. Apply the YAML config to create the VolumeSnapshotClass.

   kubectl apply -f snc.yaml 
   

3. Get the VolumeSnapshotClass.

   kubectl get volumesnapshotclass iomesh-csi-driver
   

   If successful, you should see output like this:

   NAME                             DRIVER                  DELETIONPOLICY   AGE
   iomesh-csi-driver                com.iomesh.csi-driver   Delete           24s
