Description David Hill 2021-01-04 13:05:46 UTC 
Possibility to DOS a controller with creating a boot from volume instance when the image is bigger than remaining space on filesystem.  

1)  Create a 100GB raw image file
2)  Create a boot from volume instance on a controller where /var/lib/cinder/conversion is smaller than 100GB
3)  Wait for everything to blow up through fencing

And I suspect that creating multiple concurrent volumes could also fill the partition even if the volumes are smaller.
