Ubuntu – Extending Ubuntu Partition size with the unallocated space (swap is between these two)

12.04partitioningunallocated

My Ubuntu 12.04 is set up on virtualbox, the host system is Windows 7.

When setting up my system, I created 8GB VDI hard drive. In a short time I run out of free space, so I increased the size of the VDI to ~50GB via Windows.

Now I'm trying to increase the size of my Ubuntu partition with the unallocated space gained by increasing the size of the virtual hdd.

Therefore, I've booted Ubuntu with the LiveCD and started up GParted. The problem is that I cannot increase the size of the desired partition, probably because swap is just between it and the unallocated space.

My question is – how can I move my allocated space to the neighborhood of Ubuntu partition and then enlarge it?

Here is how it looks like in GParted:

I'm also pasting the output of fdisk -l:

I can't stress this enough:

It is highly recommended to backup any important files before doing resize/move/extend operations.

The way to do it, is by deleting the swap partition, extend the partition that you want, and then re-create the swap partition.

Swap partition can only be deleted after swap is turned off:

SWAP off: sudo /sbin/swapoff -a SWAP on: sudo /sbin/swapon -a

The steps:

  1. Boot from the Ubuntu LiveCD
  2. Open terminal, and turn swap off
  3. Install GParted
  4. Extend the partiton that you want, but leave space for swap
  5. commit the changes
  6. create swap partition
  7. turn swap on

Note: If your swap is not your primary hard drive, then see SwapFaq on how to activate the swap partition
