Define "full". Disk volumes aren't like packing crates. They're more
like balloons. They grow as you add data to them.

Again, how is it "wasting space"? A disk volume doesn't preallocate
space to hold the maximum size of the number of jobs you might write
into it. A disk volume consumes only as much space as the data you
wrote into it.
