Actually this is my biggest qualm about Gluster and is both it's greatest
weakness and greatest strength. It's great as cluster storage where storage
requirements don't change, but doesn't work well as just general storage. In
real life usage, storage requirements change and it's necessary to
add/remove heterogeneous storage nodes depending on business needs. There
currently isn't a working configuration of Gluster for this after the unify
translator was removed. The unify translator isn't scalable at the high-end
It may just be a general design decision that prevents this because there's
no master node that can manage replication/rebalancing. If anybody knows a
good open-source solution please pipe up!
