...but that's what I'd expect the balance to do?  If Block (Chunk?) A
is on, say device 1 (4TB) and device 2 (2TB), why wouldn't it move
Block A to the new drive from device 1 or 2 in order to free up space
and balance/spread out usage across the drives?  Is that not what
balance's purpose is?   Or is free space required on 1 or 2 in order
to move the allocation to the new drive?

OH!  Just checked -- the balance finally cancelled after freeing up the 150GB.
