Description

Description

Add Shared Storage V2 backend configuration and validation, then expose it through NVCA Helm values and agent configuration.

Requirements

  • Support secretBackend, sharedDataBackend, rwxStorageClass, rwxUseDefaultStorageClass, rwxTaskDataSize, rwxModelCacheSize, and optional rwxResourceQuota.
  • Preserve SMB behavior when the new backend fields are omitted.
  • Deliver the configuration through NVCA_SHARED_STORAGE_CONFIG_JSON_BASE64.
  • Reject invalid backend values, incompatible combinations, and ambiguous default RWX storage-class selection.

Definition of Done

  • Unit tests cover defaults, supported backends, invalid combinations, and required RWX sizes.
  • Helm rendering preserves the base64 value as a string.
