Docker and VirtualBox(1)Set up Shared Disk for Virtual Box

I have a lot of things on my VirtualBox. But I am think to change the way I deploy, I should use docker more that I thought.

I plan to share the disk across some virtual machines and deploy only docker images.

Here is a list of what I have on these machines.
ubuntu-master
1. Spark
cd /opt/spark
sbin/start-all.sh

2. opscenter
cd /opt/opscenter
bin/opscenter -f  #start in the front ground

I will export all of them and backup them into my home NAS. I will delete all of them on my local and set up fresh ubuntu LTS for that.

1 Set up Share Driver
I create virtual machine ubuntu-master, ubuntu-dev1, ubuntu-dev2 and all of them have their own driver, and a shared driver with name shared-nas.
> sudo fdisk -l

Disk /dev/sdb doesn't contain a valid partition table

Solution:
> sudo mkfs -t ext3 /dev/sdb

It does not work.

Initiate the disk with following
> sudo fdisk /dev/sdb
>m  >n >p  >1
default for other information, then >w

It works.
> sudo fdisk -l

Format to ext3
> sudo mkfs -t ext3 /dev/sdb1

It works. Then I will configure the docker to use this share driver.

2 Auto Mount the Driver to System
Create the folder
>sudo mkdir /mnt/nas

List the UUID of my disk
> ls -l /dev/disk/by-uuid
total 0
lrwxrwxrwx 1 root root 10 Dec 11 17:45 6624adb3-86bc-4801-8275-063cdfae706b -> ../../sda5

Copy the one of sdb1, edit the file fstab
> sudo vi /etc/fstab
UUID=adcfd350-219a-414f-92a6-e175b334d970 /mnt/nas        auto  defaults 0 0

Amount the disk
> sudo mount -a

Check the amount
> df -hl /mnt/nas/
Filesystem      Size  Used Avail Use% Mounted on
/dev/sdb1        79G   56M   75G   1% /mnt/nas

3 Install and Set up Docker
> sudo mkdir /mnt/nas/docker

Installation
> sudo curl -sSL https://get.docker.com/ | sh
> sudo usermod -aG docker carl
or
> sudo gpasswd -a carl docker

Change the configuration
> sudo vi /etc/default/docker
DOCKER_OPTS="-g /mnt/nas/docker"

> docker info
Containers: 0
Images: 0
Server Version: 1.9.1
Storage Driver: aufs
Root Dir: /mnt/nas/docker/aufs

Done and try
> docker pull centos:7
> df -hl
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1        75G  1.3G   70G   2% /

/dev/sdb1        79G  242M   75G   1% /mnt/nas

File are stored in the shared NAS disk.

The problem is that I try to create a shared vdi and ask all the clients ubuntu system to load the same NAS disk. It does not work. I will try shared folder.
> sudo apt-get install virtualbox-guest-additions-iso
> sudo apt-get install virtualbox-guest-utils
> sudo mount -t vboxsf nas /mnt/nas

It works. But when I start the docker, docker throw exception in logging
> sudo less /var/log/upstart/docker.log
ESC[31mERROESC[0m[0000] [graphdriver] prior storage driver "aufs" failed: invalid argument
ESC[31mFATAESC[0m[0000] Error starting daemon: error initializing graphdriver: invalid argument

> VBoxManage modifymedium --type shareable nas.vdi

It works.
