How to increase size of qubes_dom0-root in installer?

BenT · February 15, 2023, 8:59pm

I’d like to increase the default size of qubes_dom0-root from 20G to say 40G for the purposes of automatic partitioning in the installer. I’m using a kickstart.

Kickstart-compatible answer preferred as the Anaconda graphics don’t play nice on 12th gen until kernel-latest is installed, so prefer to automate the installs.

With the default of 20G, the installer refuses to continue “not enough space in file systems for the current software selection” (am installing KDE in Dom0, Fedora, Debian, and Whonix templates).

Thanks.

# Installing Templates in Qubes 4.1

## Problem 
Qubes 4.1 has limited the size of dom0 to 20G by default.  
This means that when installing some templates, the install will fail with the message
`error an extra X required`.  
The problem is that when installing a template from an rpm package, the template is first unpacked in parts in `/var/lib/qubes/vm-templates/TEMPLATE_NAME`, and then rebuilt from those parts.

There are 2 solutions, depending on whether you want to permanently increase the size of dom0.

### 1. Resize dom0 permanently

```
sudo lvresize --size 40G /dev/qubes_dom0/root
sudo resize2fs /dev/mapper/qubes_dom0-root
```

### 2. Add more space to dom0 temporarily
The process here is to create a new thin_pool, and mount it in dom0 where the package will be unpacked.

Will update this thread when I find how to automate changing root from 20G to 40G.

Good call at the time but drives are routinely > 1T now, would be good to have this option configurable.
