It looks like your eth0 and ib0 are configured as the same IP subnet. The routing tables are likely resulting in the rdma_cm trying to use the wrong device. > [kerrg@compute-0-3 rdma]$ /sbin/ifconfig > eth0 Link encap:Ethernet HWaddr 00:30:48:BE:D9:84 > inet addr:10.1.255.251 Bcast:10.1.255.255 Mask:255.255.0.0 10.1.x.x subnet > ib0 Link encap:InfiniBand HWaddr > 80:00:00:48:FE:80:00:00:00:00:00:00:00:00:00:00:00:00:00:00 > inet addr:10.1.1.30 Bcast:10.255.255.255 Mask:255.0.0.0 10.x.x.x subnet You can try changing IB to a 10.2.x.x subnet with mask 255.255.0.0. - Sean -- 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
