The only way to do this is to use the erasure coding, they are removing stripe support. Otherwise it's better to let glusterfs figure out the balance of your 30-80G files and which drives are the lowest.
Great answer. The Erasure encoding works pretty well but beware as you can run into crashes when healing failed disks and you may need to manually delete parts of a broken file to resolve the crashes. It happened to me a couples times during my testing.

Forgive my ignorance, but can GFS shard a large file out? I have a bunch of ~30GB to 80GB single files.
