Hello everyone, I've recently setup a RouteBricks installation, and am really close to having it work, but ran into a problem I was hoping someone might be able to help me with.
I've got an HP DL380G6 server with two intel E5520 4-core CPUs, along with a dual-port intel 82598EB NIC (with two SFP+ interfaces). I followed the instructions on the RouteBricks wiki for recompiling the kernel, rebuilding the ixgbe driver with the RB patches, and installing everything. I've setup three machines in series (A -> RB -> B), and am able to ping between A and RB, and RB and B. If I set /proc/sys/net/ipv4/ip_forward on the RB server I can ping from A to B through RB (I tested this by then setting that proc field to 0 and saw the pings stop). I loaded the 'minfwtest.click' file with click-install and it seemed to load OK (dmesg didn't show any errors, nor did /click/errors). However, when I try to ping from A to B through RouteBricks, I see huge ping times: root@dcswitch73:/home/gmporter# ping 192.168.5.74 PING 192.168.5.74 (192.168.5.74) 56(84) bytes of data. 64 bytes from 192.168.5.74: icmp_req=1 ttl=64 time=13104 ms 64 bytes from 192.168.5.74: icmp_req=2 ttl=64 time=12096 ms 64 bytes from 192.168.5.74: icmp_req=3 ttl=64 time=11088 ms 64 bytes from 192.168.5.74: icmp_req=4 ttl=64 time=10080 ms 64 bytes from 192.168.5.74: icmp_req=5 ttl=64 time=9072 ms 64 bytes from 192.168.5.74: icmp_req=6 ttl=64 time=8064 ms 64 bytes from 192.168.5.74: icmp_req=7 ttl=64 time=7056 ms [snip] 64 bytes from 192.168.5.74: icmp_req=21 ttl=64 time=17136 ms 64 bytes from 192.168.5.74: icmp_req=22 ttl=64 time=16128 ms 64 bytes from 192.168.5.74: icmp_req=23 ttl=64 time=15120 ms ^C --- 192.168.5.74 ping statistics --- 43 packets transmitted, 23 received, 46% packet loss, time 42335ms rtt min/avg/max/mdev = 7056.587/18845.638/30240.430/7061.770 ms, pipe 31 Any thoughts--has anyone seen anything like this before? Also, is there a good way to debug/diagnose what might be going on inside of click on the RouteBricks server?
