-### Persistent storage

+1. Add a virtual hard drive to the VM created in Installation

+2. Start the VM

+3. Create an empty partition on the attached virtual hard drive

-The virtual machine created above lacks any persistent data storage. All

-images and containers will be lost when shutting down or rebooting the

-VM.

+    ```sh

+    sudo fdisk /dev/sda

+    n (new partition)

+    p (primary partition)

+    1 (partition 1)

+    w (write changes to disk)

+    ```

+

+4. Format the partition using ext4 

+

+    ```sh

+    mkfs.ext4 -L boot2docker-data /dev/sda1

+    ```

+

+5. Reboot

+

+    ```sh

+    sudo reboot

+    ```

+

+6. boot2docker should now auto mount the partition and persist data there. (/var/lib/docker linking to /mnt/sda1/var/lib/docker)

+

+    ```sh

+    ls -l /var/lib
