Great, thanks. I increased the log_mtts_per_seg to 5 and was able to register more memory. But one question remaining: what is then the maximum memory that one is able to register? 5 is the maximum value to this parameter, so what does it mean? cheers, Rui -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
