Resize Root Disk Image
----------------------

The safest way to increase the size of `root.img` is to turn your TemplateVM into a StandaloneVM. Doing this means it will have it's own root filesystem *(StandaloneVMs use a copy of template, instead of smart sharing)*. To do this run `qvm-create --standalone` from `dom0` Konsole.

### Resize a StandaloneVM Root Image

In `dom0` Konsole run the following command (replace the size and path):

~~~
truncate -s 20G /var/lib/qubes/appvms/standalonevm/root.img
~~~

Then start Terminal for this StandaloneVM and run:

~~~
sudo resize2fs /dev/mapper/dmroot
~~~

Shutdown the StandaloneVM and you will have extended the size of it's `root.img`


### Resize a TemplateVM Root Image

In `dom0` Konsole run the following command (replace the size and path):*Make sure changes in the TemplateVM between reboots didn't exceed 10G.*

~~~
truncate -s 20G /var/lib/qubes/vm-templates/fedora-21/root.img
~~~

Then start Terminal for this TemplateVM and run the following:

~~~
sudo resize2fs /dev/mapper/dmroot
~~~

Shutdown the TemplateVM and you will have extended the size of it's `root.img`
