Well, adding bricks could be usefull...  :)

Having to create multiple cluster is not a solution and is much more
And if you corrupt data from a single cluster you still have issues

I think would be better to add less features and focus more to stability.
In a software defined storage, stability and consistency are the most
important things

I'm also subscribed to moosefs and lizardfs mailing list and I don't recall
any single data corruption/data loss event

In gluster,  after some days of testing I've found a huge data corruption
issue that is still unfixed on bugzilla.
If you change the shard size on a populated cluster,  you break all
existing data.
Try to do this on a cluster with working VMs and see what happens....
a single cli command break everything and is still unfixed.
