That should not be a warning it should be common sense, and it is true 
for any storage device whether that storage device is used by an OS or 
for general storage.





However the issue was *Not* that the pool was full:

$ sudo lvs
  WARNING: Thin volume qubes_dom0/img-Tails maps 8.00 GiB while the 
size is only 2.00 GiB.
  LV VG Attr 
LSize  Pool   Origin Data% 
Meta%  Move Log Cpy%Sync Convert
  img-Tails  qubes_dom0 Vwi-a-tz-- 
2.00g pool00100.00 



But I deleted it anyway.

Regards,
Ulrich

Hi,

*urgently* clean up the disks. If you get a full disk qubes is likely to 
crash since some
config files are not written properly. I experienced qubes rendered 
unusable while the disk
was full. So some config files which manage the VMs got corrupted, so I had 
to boot kali
to mount the disk images and to backup all my data and then to reinstall 
qubes,
because dom0 did not wanted to start any vm, and reported some python 
errors in line xyz.
So debug the scripts or just reinstall :-(
Maybe, there is a better way, to repair qubes, but I chose the 
archeological approach,
as the success was guaranteed beforehand.

feature request: backup all config files into 3 archives and rotate them, 
so one can simply
exchange a broken state with the state before, while loosing some changes 
to memory size, net vm
and so on, but the system stays stable
/feature request.

So never ever let qubes fill your disk(s) completely. Leave some room.

Cheers

Ludwig
