C'mon guys - that has nuthin to do with ZFS or any other RAID [1].

Grocery-store rithmetic says you can't put 2 liters of wine into a 
one-liter bottle.

(though there IS a MIL-SPEC exercise called a 'blivet' that tries to get 
ten liters of sh** into a one-liter container .. ...with predictable 
mess to be dealt with, fecal matter having rather poor compression 
algorithms)

[1] Though some 'grid farm' and cousins attack the problem differently - 
sort of a JBOD confederation with (some of) the contents replicated one 
or more times and in one or more places - wherever there is space, or 
least-usage, or greatest 'quality', or most eager 'volunteer', or ....

Whole 'nuther subject, those.

And neither ZFS not HAMMER is of that family.

Not *yet*
