Vagrant 在 Ubuntu 14.04 上挂载 NFS

Question

直到今天，我的 vagrant 设置运行良好且流畅。但是发生了一些事情，我不知道是什么。

当我执行 vagrant up 时突然挂起挂载 NFS 共享文件夹。

我的猜测是由于我的主机上的某些更新导致某些东西损坏了。以下是 vagrant up --debug 命令的输出以及最近 2 天的最新更新列表。

这是 vagrant 的输出：

问题出在 udp 协议上。我从 VagrantFile 配置行中删除了 udp：

:mount_options => ['nolock,vers=3,udp,noatime,fsc,actimeo=1']

此外，不推荐udp，即使它更快。 https://github.com/mitchellh/vagrant/issues/2304

尝试重新启动 nfs 服务（在 Arch 中为我使用 sudo systemctl restart nfs-server.service）或从 /etc/exports 中删除 Vagrant 条目（它们被#VAGRANT-BEGIN 包围： ... #VAGRANT-END: comments) 然后重启服务。

对于 18 月 18 日仍在环顾四周的其他人，我发现了我的案子的罪魁祸首。

在我的例子中，即使安装了 nfs-kernel-server 和 nfs-common，nfs-server 包似乎也丢失了，我安装了 nfs-server 并且 vagrant up 工作正常。 Vagrant 2.0.3 和 Virtualbox build 5.2.18_Ubuntu r123745
