   Well, not quite. It has a side-effect that if you have an
over-allocation of space to one or other of data/metadata, it will
serve to reduce that allocation, giving back the over-allocated space
to the free pool, from where it can be reallocated by the other group
type.

   So if you have, say 5G allocated for metadata, but only 500M used,
you could gain back a large amount (but probably not all) of the
unused 4.5G by running a balance.
