### Resizing \`root.img\` Size
|
||
|
|
|
||
|
|
The safest way to increase the size of \`root.img\` is to do it for a standalone
|
||
|
|
VM (qvm-create --standalone) - which has its own root filesystem
|
||
|
|
(copy of template, instead of smart sharing).
|
||
|
|
But it should also work for a normal template (as long as changes in the
|
||
|
|
template between reboots didn't exceed 10G).
|
||
|
|
|
||
|
|
Replace the size and the path (name) of the template as wished and run your
|
||
|
|
modified command:
|
||
|
|
```
|
||
|
|
truncate -s 20G /var/lib/qubes/vm-templates/fedora-21/root.img
|
||
|
|
```
|
||
|
|
|
||
|
|
Then start your template or standalone VM and run:
|
||
|
|
```
|
||
|
|
sudo resize2fs /dev/mapper/dmroot
|
||
|
|
```
|
||
|
|
|
||
|
|
after that shutdown the template.
|
||
|
|
|
||
|
|
Then you should have extended \`root.img\` in your VM/template
|
