NFSv4 在挂载时挂起

服务器重启后，NFS 挂载命令无限期地挂起在客户端上。

我正在运行这个命令：mount -t nfs -v 10.17.25.27:/DATA/projects/assets-db/log-apache test

我的 NFS 服务器是：10.17.25.27，客户端 IP 是10.17.25.152

我已经为 nfs 启用了 syslog 调试并且看到以下错误：

我看到这些类型的日志行重复出现。

当我rpcinfo -p 10.17.25.27在客户端上运行时，我看到：

请注意，使用 NFS 版本 3 进行挂载是可行的，但我需要版本 4 的功能，因此我无法降级到该协议的旧版本。

我使用CentOS 7.2内核3.10.0-514.26.2.el7.x86_64

答案1

我们没有发现为什么我们的 NFS 突然关闭，并且在重启后，客户端无法挂载任何导出的文件系统。我们尝试重启所有服务器，打开机器之间的所有端口，但都无济于事。

然而，我们将内核从版本升级3.10.0-514.26.2.el7.x86_64到3.10.0-862.11.6.el7.x86_64
