Yeah, intentionally so...  As I recall, if your snapshot volume ran out of
space, the snapshot would become corrupted.  The original copy was fine, it
was just the snapshot that died.  Which makes sense based on how it's
implemented.  I don't recall that I've tested it this millennium though.

So writes on your main file-system should start returning write failures as
if the disc were full, if the snapshot volume is full?  Not sure that'd be
good...

That's why you test it before deploying it in production.  We did and love
it...
