--- Comment #3 from Dan Lambright <dlambrig at redhat.com> ---
DHT does not accept creation of files beyond the brick size. So I am not sure
if we can fix the test the way it is structured, but nithya can confirm.

In practice the hot brick would be 10s or 100s of GB. A file created would be a
fraction of that size. As files are created on the hot tier it would become
more full, until eventually a watermarked was crossed. At that time files would
be created on the cold tier.
