Hi, Admittedly not a DRBD issue per se, but I guess this list represents quite some experience in the area: I have two gigabit NICs bonded in balance-rr mode for DRBD sync. They are directly linked (no switch) to the other other pair in the other DRBD node. Before syncing things I was testing the performance and failover. Netperf shows for instance this: iscsi2:/etc/sysconfig/network # netperf -p 2222 -H 10.0.2.3 TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 10.0.2.3 (10.0.2.3) port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 87380 16384 16384 10.00 977.83 Pulling one cable gives me about the same speed. I would expect it to be at least 20% slower. It seems the round robin does not speed up things. The bonds on both sides show up fine in /proc/net/bonding/bond0. Anyone any idea what I'm doing wrong? Cheers, Bart
