CRDs for VAST snapshots are a prerequisite for using VAST snapshots. The CRDs are required if your deployment includes one or more snapshot classes.

The driver's logic for creating snapshot classes varies depending on whether you specify the Kubernetes secret as a global or a storage class-specific option:

  • If the driver's Helm chart configuration file (values.yaml) has secretName and Endpoint specified as global options (on top of values.yaml), the driver follows legacy logic and creates one snapshot class named vastdata-snapshot to be used for all PVCs. This configuration requires that you install the CRDs for VAST snapshots during driver deployment.

  • When secretName and secretNamespace are specified within one or more storage classes (or under StorageClassDefaults), the driver creates snapshot classes only when they are defined explicitly. This means that in this case, you need to install the CRDs for VAST snapshots only when you have an explicit snapshotClass definition in place.

Run the following commands to install the CRDs for snapshots:
