+
+
+解决方法是在 `prometheus` 配置持久化的 `volumeClaimTemplate` 下把 `selector: {}` 注释
+
+```yaml
+    storageSpec: 
+    ## Using PersistentVolumeClaim
+    ##
+     volumeClaimTemplate:
+       spec:
+         storageClassName: openebs-hostpath
+         accessModes: ["ReadWriteOnce"]
+         resources:
+           requests:
+             storage: 50Gi
+         #selector: {} # 注释这一行
+```
