k8s集群挂载nfs出现mount failed: exit status 32

错误描述
环境：Debian 10 buster
OS：x86_64 Linux 4.19.0-6-cloud-amd64

Pod出现FailedMount：MountVolume.SetUp failed for volume “pv” : mount failed: exit status 32

kubectl describe 后日志输出为mount.nfs: access denied by server while mounting …

查看日志输出为： cat /var/log/messages

可以看到使用的是nfsv4.1

解决办法：
vi /etc/sysconfig/nfs 输入

# Turn off v2 and v3 protocol support
RPCNFSDARGS="-N 2 -N 3"
# Turn off v4 protocol support
RPCNFSDARGS="-N 4" 

然后重启nfs服务

/etc/init.d/nfs-kernel-server restart

重现创建pv、statefulset即可
