Unable to mount shared folders

[kyleskrinak]

I ran:

dsh self-update
dsh update prerequisites
dsh update boot2docker

which, most notably, updated my VBox to 5.1.2, which I've now learned is an issue with Vagrant, as per this ticket #155

So I've downgraded my VBox to 5.0.20 (which it was at prior to the upgrade) however, I am seeing this error:

Vagrant was unable to mount VirtualBox shared folders. This is usually
because the filesystem "vboxsf" is not available. This filesystem is
made available via the VirtualBox Guest Additions and kernel module.
Please verify that these guest additions are properly installed in the
guest. This is not a bug in Vagrant and is usually caused by a faulty
Vagrant box. For context, the command attemped was:

set -e
mount -t vboxsf -o uid=id -u docker,gid=getent group docker | cut -d: -f3 .ssh /.ssh
mount -t vboxsf -o uid=id -u docker,gid=id -g docker .ssh /.ssh

The error output from the command was:

gid= requires an argument (i.e. gid==)
mount: mounting .ssh on /.ssh failed: Protocol error

shelling into the b2d box, I run

grep -i vbox

and see:

vboxsf 40960 0
vboxguest 180224 2 vboxsf

Only a partial list of what should be running.

I'm unclear of what I can do next to get my drude environment operational again?

Hi @kyleskrinak

You are not the first reporting this issue. Looks like vagrant did something wrong in their last version which brought a retro-bug.

Looks like downgrading to VirtualBox 5.0.20 and vagrant 1.7.4 solves the issue.

@achekulaev Thanks for the suggestions. I did try the vagrant vbguest plugin before I posted. However, I get this message:

The guest's platform ("tinycore") is currently not supported, will try generic Linux method...

which leads to

An error occurred during installation of VirtualBox Guest Additions 5.1.2. Some functionality may not work as intended.

I also previously tried vagrant ssh into the b2d machine to run this command:

sudo ln -s /opt/VBoxGuestAdditions-4.3.10/lib/VBoxGuestAdditions /usr/lib/VBoxGuestAdditions

which I presume should be

sudo ln -s /opt/VBoxGuestAdditions-5.1.2/lib/VBoxGuestAdditions /usr/lib/VBoxGuestAdditions

Or whichever version of VBox I'm running. However, the b2d machine only lists

bootlocal.sh
bootscript.sh
bootsync.sh
shutdown.sh
tcemirror

There's no such dir in /opt.

I'm using Drupal VM until I resolve this, but really miss drude.

Have you tried downgrading to VirtualBox 5.0.20 and vagrant 1.7.4?

[kyleskrinak]

I had only downgraded VB previously. Downgrading both did the trick. Thanks! Drupal VM is nice, but way overkill, storage-wise.

[achekulaev]

Great!

I will keep this issue open and update it once it's safe to update to the latest versions.
Going forward we'll get rid of Vagrant.

This is a duplicate of #155

Closing in favor of the issue in the upstream project:
lmakarov/boot2docker-vagrant#83

Let's move further discussions there.
