I've seen you talking about the new clustering approach, can you elaborate a little (maybe in a separate topic/mail)?.
Given the state of distributed storage solution, shouldn't that be considered?. For example Nutanix adds capacity with each new node and the interface is just NFS. Wouldn't that make it easier for the management of upper layers?
Pomegranate or LyzardFS might be an option?
