The wire protocol that is used to retrieve the information 'fs' reports
cannot currently represent amounts larger than 2TB, so you get undefined
results from 'fs lq' on such partitions. The 'vos' command suite uses a
different wire protocol which can represent them.

There is work being done to alter the protocol to allow for >2TB
partition sizes, but new RPCs are still a little ways out at this point.
