vagrant - vagrant shell 脚本失败，出现无法解释的错误```只读文件系统（运行时错误）```

Question

我在 vagrant 中有一个小配置 shell 配置脚本（安装木偶失败的东西..）脚本：

#!/bin/bash
echo 'provisioning librarian'
gem install librarian-puppet
librarian-puppet install

运行良好，sh prescript.sh 但从 vagrant 配置失败：

遵循此处的建议，我已经更改（使用 sublimetext2）以 unix 结尾的 windows 行。但仍然没有任何想法

Answer 1

一些可能性：

您可能在 VirtualBox 中使用不支持符号链接的共享文件夹（除非已修复）。据说VBoxManage现在有一个命令可以解决这个问题，比如

VBoxManage setextradata VM_NAME VBoxInternal2/SharedFoldersEnableSymlinksCreate/SHARE_NAME 1

或者这个进入 Vagrant 文件（假设 SHARE_NAME 在这个文件中是 v-root ）：

config.vm.customize ["setextradata", :id, "VBoxInternal2/SharedFoldersEnableSymlinksCreate/v-root", "1"]

For more possibilities see: https://www.virtualbox.org/ticket/10085#comment:12 or a long forum on the topic at https://github.com/mitchellh/vagrant/issues/713

Another possibility is that you might be running the script so early in the boot process that the root (or possibly just the /tmp) filesystem hasn't been remounted in read/write mode, say, if the script is being run from one of the /etc/rc.2/S(num)(name) scripts and the (num) is too low.

I just ran into this error while vagrant uping a virtual machine. In my case, the problem appears to be that a previous copy of the virtual machine was running in the background. Some history:

• A VM for this same project had previously crashed (hours before) and I had to close the terminal window (macOS) and restart the VM (using vagrant halt + vagrant up).
• This appeared to fix things and I proceeded along normally and forgot about it.
• Later, after I made a change to the Vagrantfile and wanted to make sure everything worked, I destroyed the VM and vagrant uped a new one, only to run into this error.
• After reading the answer by @AlexNorth-Keys, I remembered the fact that the VM had previously crashed so I decided to restart my computer and then everything worked. I'm pretty sure that a copy of the crashed VM must have been running in the background and it's sharing of the project folders was causing issues.

Obviously this is just a guess, but restarting the host machine fixed the issue.

In my case the reason was /etc/fstab got modified on Vagrant instance. If you also played with this file and got into trouble, here is possible solution:

1. vagrant ssh
2. mount -o remount,rw /
3. now edit the file /etc/fstab, eg. nano /etc/fstab
4. provide needed changes (for example remove nolock option)
5. exit vagrant
6. vagrant reload
