After install the helm chart, there will an extra useless volume for BE.

  volumes:
  - name: be1-data
    persistentVolumeClaim:
      claimName: be1-data-kube-starrocks-be-0
  - name: be-log
    persistentVolumeClaim:
      claimName: be-log-kube-starrocks-be-0
  - name: be0-data
    persistentVolumeClaim:
      claimName: be0-data-kube-starrocks-be-0
  - emptyDir: {}
    name: be-data
  - configMap:
      defaultMode: 420
      name: kube-starrocks-be-cm
    name: kube-starrocks-be-cm

Expected behavior

Remove the extra useless be-data volume
