qcow2 images can be larger than 16 TB, but if you actually write that
much data to them, you can't store them on ext4, because obviously they
are still just files and the filesystem limit applies.

You'll need to switch to a more scalable filesystem such as XFS to be
able to write more then 16TB of data.
