There appears to be an issue with using custom StorageClasses on the Helm chart.

volumeClaimTemplates:
      - name: data-volumeclaim-template
        reclaimPolicy: Retain
        spec:
          accessModes:
            {{- toYaml .Values.persistence.accessModes | nindent 12 }}
          resources:
            requests:
              storage: {{ .Values.persistence.size }}
        {{- $storageClass := default .Values.persistence.storageClass .Values.global.storageClass -}}
        {{- if $storageClass -}}
        {{- if (eq "-" $storageClass) }}
          storageClassName: ""
        {{- else }}
          storageClassName: {{ $storageClass }}
        {{- end }}

I configured my persistence of clickhouse to a custom storageClass but this does not seem to work properly:

clickhouse:
  persistence:
    size: 500Gi
    storageClass: managed-csi-premiumv2

Could anyone fix this so that we are able to use premiumv2 storage classes on Azure? 🙂
