我有两个 NetApp NFS 共享，每个都安装在一个客户端上。将文件复制到共享上时，客户端挂起，并在“/var/log/messages”日志文件中出现“NFS 服务器 xxx 没有响应，仍在尝试”，随后出现“nfs 服务器 xxx 正常”消息。
我已经尝试在 Netapp 上仅激活 NFS v3 或 v4，尝试了不同网络中的几个其他客户端，并使用了几种不同的挂载选项。共享已经运行了几个月，在对配置进行简短评估后，Netapp 端没有任何变化。
为了测试目的，我在客户端上创建了一个 NFS 共享，并将其安装在另一个相关客户端上 -> 运行正常。
我附加了一些日志 - 也许有人能比我得到更多...
谢谢您对此的任何提示！
编辑：
确实存在第 8 层问题：我们当然有一个单独的网络用于 NFS 通信。尽管在这种情况下可以通过其他几个网络连接并使用 NFS 连接，但某些网络组件上的流量显然中断了。使用正确的网络解决了这个问题。
