[Gluster-users] RDMA Problems with GlusterFS 3.1.1

>From the logs its evident that the reason for completion queue creation failure is that the number of completion queue elements (in a completion queue) we had requested in ibv_create_cq, (1024 * send_count) is less than the maximum supported by the ib hardware (max_cqe = 131071).

I patched the source code and rebuilt GlusterFS. Here are the full logs:
