I downloaded 50gb on my AppVM and after this i cant start any other VM with error “Cannot create new thin volume. free space in thin pool qubes_dom0/vm-pool reached threshold”
I am tried to reboot system. After reboot i cant even log in because my keyboard dont work. I guess because sys-usb cant start.

How can i solve this? I am on newbie level
Thank you

Connect a PS/2 keyboard if you have such an option, log in and do this:

If you don’t have PS/2 keyboard, the easiest way is probably to boot from a different OS’s live USB stick, mount the dom0 lv, and do the same thing.

Once you can boot properly again, free some space or reduce revisions_to_keep of the 50 GB volume using qvm-volume config $vm:$vol revisions_to_keep $n with:

  • $vm is the name of a qube
  • $vol is the name of a volume, for example root (/ by default) or private (/home/ and /usr/local/ by default)
  • $n is the number of revisions, 2 by default so that you could revert if something goes wrong.

That being said,

is obviously not very secure, unless you trust the live recovery OS as much as you do dom0.

p.s. You need help with that or you can figure out how to unlock an encrypted partition (assuming it is) and mount an lv by yourself?

p.p.s Alternatively, you can delete some volumes instead of changing the margins, see Disk troubleshooting — Qubes OS Documentation (closer to the end, it’s discussing legacy qubes first)

Thanks for your answer.
Can it be USB TYPE C keyboard?
Or just PS/2?

Actually I was wrong, you can get usb devices to dom0 in case your sys-usb breaks, here’s the solution from Getting a serial console on USB-only Qubes laptop :
