NFS shared folder mounting hangs

[mdarse]

Hi,

I tried to create a simple VM using $ vagrant init mitchellh/boot2docker and adding a shared folder, but it hangs during mounting:

$ vagrant up
==> default: Checking if box 'mitchellh/boot2docker' is up to date...
==> default: Verifying vmnet devices are healthy...
==> default: Preparing network adapters...
==> default: Fixed port collision for 22 => 2222. Now on port 2200.

==> default: Configuring network adapters within the VM...
==> default: Exporting NFS shared folders...
==> default: Preparing to edit /etc/exports. Administrator privileges will be required...
Password:
==> default: Mounting NFS shared folders...

The shared folder is defined like this:

config.vm.synced_folder ".", "/vagrant", type: "nfs"

I'm running OS X 10.9.3 with Vagrant 1.6.3.

Any ideas ?

Thanks,
M.

I think this has something to do with vagrantfile.tpl:

# Disable synced folders because guest additions aren't available
config.vm.synced_folder ".", "/vagrant", disabled: true

As I understand it (but I’m new to this!), the guest additions are required for all synced folder types. It’s not clear to me whether adding them should be requested here, or with @boot2docker (it downloads their image).

Same issue. FWIW I was able to get NFS synced folders working with this fork - https://vagrantcloud.com/yungsang/boxes/boot2docker

I have a little bit more info to add if it helps. After the mount fails it hangs because it keeps sending SSH keep alives.

...
DEBUG ssh: Sending SSH keep-alive...
DEBUG ssh: Sending SSH keep-alive...
DEBUG ssh: Sending SSH keep-alive...
...

Here is what Vagrant is presumably choking on.

DEBUG ssh: Re-using SSH connection.
 INFO ssh: Execute: mkdir -p /vagrant (sudo=true)
DEBUG ssh: Exit status: 0
DEBUG ssh: Re-using SSH connection.
 INFO ssh: Execute: mount -o 'vers=3,udp' 192.168.33.1:'/Users/jmreicha/about.me/main' /vagrant (sudo=true)
DEBUG ssh: stderr: mount: RPC: Unable to receive; errno = Connection refused

DEBUG ssh: Exit status: 110
 INFO retryable: Retryable exception raised: #<Vagrant::Errors::LinuxNFSMountFailed: The following     SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

mount -o 'vers=3,udp' 192.168.33.1:'/Users/jmreicha/about.me/main' /vagrant

Stdout from the command:

Hey,

if you take a look at:

dduportal/boot2docker-vagrant-box and this PR: boot2docker-vagrant-box#5.

You need to start nfs-client before mounting any folder.
