- nfs.mountOptions="nfsvers=3,timeo=600,nolock"

- nfs.mountOptions="nfsvers=3,timeo=600,nolock 主要是这行nolock设置
安装报错：

Failed to deploy addons: failed parsing --set data: key "nolock\"" has no value

看了下nfs-client-provisioner这个chart，nfs.mountOptions这个参数是个列表，这个可以用values.yaml配置文件的方式配置。

在自己机器上搞个custom-nfs-client-values.yaml, 修改成自己的配置后，把这个文件路径填到values那里。

server: xxx path: xxx mountOptions: - nfsvers=3 - timeo=600 - nolock storageClass: defaultClass: true

  addons:
  - name: nfs-client
    namespace: kube-system
    sources:
      chart:
        name: nfs-client-provisioner
        repo: https://charts.kubesphere.io/main
        values: /xxx/custom-nfs-client-values.yaml

Cauchy 大佬，我现在使用外置文件的方式不行了，是不让这样写了吗：

Error: Failed to download cluster config: Unable to convert file to yaml: yaml: unmarshal errors:
  line 52: cannot unmarshal !!str `/root/k...` into []string
