The problem is that ordinarily, part of the process of moving a volume 
involves making a clone of it, and with the partition completely full, 
there is no room to write even the small amount of data required to create 
the clone.

Fortunately, we now have a solution to this problem.  If you use the -live 
switch to 'vos move', it will use the live RW volume instead of making a 
clone.  This means the volume will be "busy" for the entire duration of the 
move, instead of just a short time at the beginning and end of the 
operation.  However, it will work even when the source partition is full.
