Cloning .vdi was Successful However Disk Space Did Not Increase

I'm running VirtualBox 4.3 and have Ubuntu 12.04.2 x64 guest, which has run out of disk space. I need to install VirtualBox Guest Additions and I have gone thru and deleted large files along with old kernels to free up more space.

I found this step-by-step tutorial here to increase disk space:

Hajuria's Blog: How to increase Virtualbox disk size in 9 easy steps

From Windows 7 MS DOS ran this successfully
C:\Program Files\Oracle\VirtualBox>VBoxManage modifyhd --resize 12920 "C:\Users\
cmmiller\VirtualBox VMs\Ubuntu 12.04.2 x64 Clone 001\Ubuntu 12.04.2 x64 Clone 00
1.vdi"
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

When I log into the Ubuntu VM and run df -h, it shows the following:
$ df -h
Filesystem                  Size     Used     Avail       Used%    Mounted On 
/dev/sda1                   6.0G    5.3G     401M      94%       /

I'm not understanding how VBoxManage says it ran successfully along with no issues of cloning the original .vdi file, however once logging into the Linux VM, it shows decrease of HD Space from 8 GB to 6 GB.

    Expanding the disk is not going to change the size of the partition. Note how in your link the additional space showed up as unallocated space. My guess would be your 8GB disk had 2GB allocated to swap, and /dev/sda1 has always been 6GB. If you want more space for /dev/sda1, you'll also have to extend the partition as well.

    Expanding on Alan's post,
    Most likely the additional space isn't allocated and you'll need to resize the partitions or create a new one from the free space.

    Just to verify that you do have the space run the following:
    dave@ubuntu:~$ sudo fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders, total 20971520 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00010d1e


   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *        2048    14680063     7339008   83  Linux
/dev/sda2        14682110    16775167     1046529    5  Extended
/dev/sda5        14682112    16775167     1046528   82  Linux swap / Solaris

    The first line of output should have the total capacity of the attached device: 
    Disk /dev/sda: 10.7 GB, 10737418240 bytes



    dave@ubuntu:~$ sudo df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1       6.8G  3.0G  3.5G  47% /
udev            492M   12K  492M   1% /dev
tmpfs           101M  756K  100M   1% /run
none            5.0M     0  5.0M   0% /run/lock
none            501M  144K  501M   1% /run/shm

    won't be a good indicator as the unallocated space isn't yet part of your file system.

    Here is my listing from fdisk
                     
[LIST=1]
[*]root@ubuntu64vm:~# fdisk -l
 
Disk /dev/sda: 13.5 GB, 13547601920 bytes
255 heads, 63 sectors/track, 1647 cylinders, total 26460160 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0005a181
 
   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *        2048    12582911     6290432   83  Linux
/dev/sda2        12584958    16775167     2095105    5  Extended
/dev/sda5        12584960    16775167     2095104   82  Linux swap / Solaris 
[/LIST]

    To me /dev/sda5/ is the new space that I created.

    From what I understand reading various threads I must use gparted to convert that space over to ext4 and then the .vdi file will see the newly created space.

    The only issue I'm having now is that my disk space is full and I won't be able to install gparted from apt-get.

    I have downloaded System Rescue however I'm not sure what to do next, looking online for solutions are confusing. To me, it looks like I will have to mount this .iso, however it is an .iso that lives on the Host, not the Guest. The reason I'm trying to add more space is because I'm trying to install Guest Additions.

    Can anyone advise how to do this or if there is a better way to go about this.

    ***Disclaimer: there is certainly the potential for data loss when working with partitions***

    First, make a backup of this VM somewhere.

    Second, This blog post should certainly help, give it a read:
    Live resizing of an ext4 filesytem on linux | The silence of the code

    One additional note, make sure nothing else is writing to disk , run a quick " ps aux"
    One more additional note, if you loose track of the UUIDs you can run this to get that info back : 
    dave@ubuntu:~$ sudo blkid
[sudo] password for dave:
/dev/sr0: LABEL="VBOXADDITIONS_4.3.12_93733" TYPE="iso9660"
/dev/sda1: UUID="ab2614d0-de7a-4dd9-bd85-1a76110afc70" TYPE="ext4"
/dev/sda5: UUID="a2e3f9cb-0dc0-488a-85de-820fd378fa00" TYPE="swap"

    Though, I highly recommend you log your terminal session or give yourself some mad scroll back buffer before even starting, just in case you need to back track.

    Third, make sure your backup VM works.

    Fourth, re-read then attempt !

    Because Imma karma whore :P

    Here's the annotated version :

    Basically:
    -Remove the partitions
    -Add the resized partitions
    -Save the partition information
    -Reboot
    -Run resize2fs, because it does some magic
    -Take care of the updated swap partition information in various places




    So do this: 
    login as: dave
dave@ubuntu:~$
dave@ubuntu:~$ sudo fdisk -l
