如何解决Pod 无法挂载由臭氧 CSI 配置器创建的持久卷
我正在使用 kubernetes 部署 ozone（hdfs 的子程序），并且基本上遵循 here 和 here 的说明（只需几步）。
首先，我创建了几个带有本地目录的主机路径的 pv，然后通过将 nfs 声明更改为主机路径声明，对 ozone/kubernetes/example/ozone 中的 yaml 进行了轻微编辑：
volumeClaimTemplates:
- Metadata:
name: data
spec:
storageClassName: manual
accessModes: ["ReadWriteOnce"]
resources:
requests:
storage: 5Gi
selector:
matchLabels:
type: local
并且我注释掉了 datanode-stateful.yaml 中的 nodeAffinity 设置，因为我的 kubernetes 只有主节点。
部署成功。
然后我按照csi协议中的说明应用了csi和pv-test，pv（s3v中的bucket）是自动建立的，pvc确实绑定了pv，但是test pod停在了containerCreating。
附加 pv-test pod desc：
