I am still asking myself how such bug could happen on a clustered storage software, where adding bricks is a base feature for scalable solution, like Gluster. Or maybe is it that STM releases are really under tested compared to LTM ones ? Could we states that STM release are really not made for production, or at least really risky ?

Sorry if the question could sounds a bit rude, but I think it still remains for newish peoples that had to make a choice on which release is better for production ;-)
