Kubernetes nfs-subdir-external-provisioner卡在ContainerCreatin

Question

我正在尝试安装一个nfs-client-provisioner并使用它运行mongodb。不幸的是，nfs-client- provider挂在ContainerCreating中，并显示&;Warning FailedMount 3m35s (x13 over 37m) kubelet无法挂载卷:unmounted volumes=[nfs-client-root]， unattached volumes=[nfs-client-root]:超时等待条件"。

• nfs服务器配置在同一台VPS机器(Debian 10)上。
• 我可以用debian 10从第二个vps上挂载和写入文件。
• 集群设置为K0s
• 我有一个错误的舵图和手动安装。

任何帮助都是感激的查看更多信息:

命令使用helm:

helm install nfs-subdir-external-provisioner nfs-subdir-external-provisioner/nfs-subdir-external-provisioner 
--set nfs.server=47.122.181.39 
--set nfs.path=/data/nfs-storage

sudo k0s install controller --enable-worker
sudo k0s start
sudo cp /var/lib/k0s/pki/admin.conf ~/admin.conf
export KUBECONFIG=~/admin.conf

你试过了吗:

nfs.mountOptions = {
nfsvers = 4
}

我也使用了这个提供程序。它只适用于nfs4。还要检查NFS服务器的挂载点是否是根服务器。如果您的提供程序已配置并准备好，请尝试重新创建pvc。
