I want to add a new directory to the data directory, but I found that STS does not automatically create PVC. What do I need to do

conf.yaml

  cassandra:
    serverVersion: "4.0.1"
    datacenters:
      - metadata:
          name: dc1
        size: 3
        storageConfig:
          cassandraDataVolumeClaimSpec:
            storageClassName: open-local-lvm
            accessModes:
              - ReadWriteOnce
            resources:
              requests:
                storage: 5Gi
          additionalVolumes:
            - name: data01
              mountPath: /opt/tmp01
              pvcSpec:
                storageClassName: open-local-lvm
                accessModes:
                  - ReadWriteOnce
                resources:
                  requests:
                    storage: 1Gi
            - name: data02
              mountPath: /opt/tmp02
              pvcSpec:
                storageClassName: open-local-lvm
                accessModes:
                  - ReadWriteOnce
                resources:
                  requests:
                    storage: 2Gi
            - name: data03
              mountPath: /opt/tmp03
              pvcSpec:
                storageClassName: open-local-lvm
                accessModes:
                  - ReadWriteOnce
                resources:
                  requests:
                    storage: 3Gi
        config:
          jvmOptions:
            heapSize: 512M
          cassandraYaml:
            cdc_enabled: true
            counter_write_request_timeout_in_ms: 10000
            data_file_directories:
              - /opt/tmp01
              - /opt/tmp02
              - /opt/tmp03

The storage configuration for data03 was added later. After I applied it again, I found that data03 PVC was not created and the pod restart failed

log:
