NFS问题：客户端可以将共享挂载为NFSv3而不是NFSv4 – 或者如何debuggingNFS？

问题描述

我有一个运行Debian的文件服务器。在这上面我有几个NFS共享。当我使用NFSv3（mount.nfs 10.0.0.51:/exports/video/mnt -o vers = 3，soft，intr，timeo = 10）从客户端挂载共享时，它可以工作。但是，由于安全性和性能的提高，我想使用NFSv4。当我尝试在malbec上挂载一个NFSv4共享时，mount命令会挂起，最后在2分钟后超时。

如何让客户端将NFSv4共享挂载为NFSv4？

如何解决NFS问题？系统日志中没有客户端和服务器上的信息。

我的configuration有什么错误？

事实：

服务器是corvina（10.0.0.51）
客户是malbec（10.0.0.1）

马尔贝克运行的Ubuntu 12.04服务器运行Debian 7 wheezy

两者都通过1 GbE LAN连接。防火墙closures。

rpcinfo将

好。我想我解决了这个问题。看起来我在/ etc / default / nfs-kernel-server中的RPCNFSDCOUNT中有一个“-T”。这将禁用NFSv4所需的TCP。删除-T并重新启动nfs-kernel-server解决了这个问题。
