Hi Larry,

That's not the correct size, that's the current max size of the volume
(of course there is always autogrow), but the current used size is 4T,
however I'm pretty sure that includes snapshots.  I'm not able to tell
from my workstation for sure if that includes snapshots or not, so you
should probably check directly.
