Thanks Christopher, BTW, A few more questions: - If something goes wrong during the process of joining the nodes, is it possible to make a rollback? If true, how? - Should I look again to the leveldb configurations. It has been working pretty smoothly for more than one year, but 6 more nodes suggests that some tuning may be needed..
