# Getting “no space left on device” Errors with Boot2Docker?

If you're using Boot2Docker with a large number of images, or the images you're working
|

|
-with are very large, you might run into trouble if the Boot2Docker VM's volume runs out of
|
|
|

## 4. Download a disk partitioning tool ISO

To resize the volume, you'll need a disk partitioning tool like [GParted](http://gparted.sourceforge.net/download.php/).

|

-Once you've downloaded the tool, add the ISO to the Boot2Docker VM’s IDE bus. You might need to
