我正在使用 PVC 将卷附加到 grafana 的一个部署，但它超时并且容器保持在创建阶段。 存储类

预期结果 - 卷应正确附加并且 pod 应处于运行状态。

我检查并创建了存储类、PVC 和 PV。

编辑 1 将命名空间添加到 PVC 中，如下所示，但仍然失败：

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: grafana-claimtest
  namespace: grafana-proxytest
spec:
  accessModes:
    - ReadWriteOnce
  volumeMode: Block
  storageClassName: grafana-storagetest
  resources:
    requests:
      storage: 10G

仍然出现以下错误：

根据上述日志的一件事，我说附加成功，但安装 grafanapdtest 失败，我无法理解。聚氯乙烯细节：

get pvc -n grafana-proxytest
