Linux Kubernetes-本地存储-节点协作不工作

我试图让持久本地存储工作，我创建了以下PV、PVC和部署。但pod因错误而陷入挂起状态：

Type     Reason            Age                 From               Message
  ----     ------            ----                ----               -------
  Warning  FailedScheduling  63s (x7 over 8m8s)  default-scheduler  0/3 nodes are available: 1 node(s) had taint {node-role.kubernetes.io/master: }, that the pod didn't tolerate, 2 node(s) didn't find available persistent volumes to bind.

我有3个节点->1个主节点，2个工作节点

不知道我做错了什么。

PersistentVolume的路径只是一个目录，而不是装载的存储设备。

我的问题是PersistentVolumeClaim的

选择器。
在PV中添加标签并在PVC中选择该标签修复了我的问题
