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
|
|
|
|
Shut down the TemplateVM, as well as all VMs based on that template (since they
|
|
share `root.img`).
|
|
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 only the TemplateVM and run the following. Note that if you are
|
|
resizing the TemplateVM used by, e.g., your NetVM, you may need to disable
|
|
networking so when the TemplateVM is started, it does not autostart other VMs
|
|
based on the same `root.img`. Otherwise you will get an error message `Nothing
|
|
to do!`.
|
|
|
|
~~~
|
|
sudo resize2fs /dev/mapper/dmroot
|
|
~~~
|
|
|
|
Shutdown the TemplateVM and you will have extended the size of it's `root.img`.
