【问题描述】：

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。

突然间，当我 vagrant up 时，它在挂载 NFS 共享文件夹时挂起。

我的猜测是，由于我的主机上的一些更新，有些东西坏了。以下是 vagrant up --debug 命令的输出以及过去 2 天的最新更新列表。

这是 vagrant 的输出：

【参考方案1】：

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: ... #VAGRANT-END 包围: cmets) 然后重启服务。

【讨论】：

如果你的主机是 ubuntu 做service nfs-server restart

【参考方案2】：

问题在于 udp 协议。 我从 VagrantFile 配置行中删除了 udp：

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

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

【参考方案3】：

对于仍在四处张望的其他人，在 18.04，我发现了我的罪魁祸首。

在我的情况下，即使安装了 nfs-kernel-server 和 nfs-common，看起来 nfs-server 软件包也丢失了，我安装了 nfs-server 并且 vagrant up 没有问题。 Vagrant 2.0.3 和 Virtualbox 构建 5.2.18_Ubuntu r123745
