Question

我正在构建一个由Virtualbox管理的虚拟机，打算用作Cassandra / OpsCenter的节点。

在设置过程中，我发现同步文件夹无法正确安装在vagrant up上。通过这个，我的意思是当我尝试从VM内部touch /vagrant/foo.txt启动后，我收到权限错误。而且，如果我在主机上的项目目录中创建了一个文件，它就不会显示在来宾VM上的/vagrant中。

我没有在我的Vagrantfile中设置同步文件夹，仅使用默认行为。但是当我vagrant reload时，一旦我SSH回到VM，同步文件夹突然按预期工作。

vagrant up或vagrant reload的日志中没有错误。

在阅读了其他一些SO帖子之后，我同时运行了vagrant up --debug和vagrant reload --debug，并取出了我能找到的与mount操作相关的所有输出。

下面粘贴了Vagrantfile，配置代码和选定的日志。知道是什么给了这里吗？ TIA。

我正在使用Virtualbox 4.3.12 r93733，Vagrant 1.6.3，Hahsicorp Ubuntu 12.04 64-bit VM，在OSX Mavericks 10.9.4上运行。

  config.vm.provision :shell, path: "bootstrap.sh"

我认为这是配置脚本末尾的reboot命令。我在评论你的配置脚本步骤的同时做了几次测试，它总是正常工作。使用配置脚本，如您所述，它将失败。在最后删除reboot后，共享文件夹安装似乎总是有效。

我发现这篇博文可能会让人更清楚：How to Reboot a Vagrant Guest VM During Provisioning。他们描述了在重新启动后重新安装共享文件夹的必要性。

我不确定你是否需要重启。 Cassandra和OpsCenter都不会要求它，我认为你的配置设置会正常工作。

您可以进行的另一项优化是减少apt-get update次呼叫的数量。根据网络连接速度，这些可能会非常慢。例如，您可以将debian.datastax.com配置步骤移至顶部，拨打apt-get update一次，然后执行所有安装。

在流浪者之后，默认同步文件夹不起作用，但在流浪汉重新加载后也是如此
