Hi All; I create a distributed gluster volumes by 4 server. Some of server create nic bond, bond mode is Adaptive load balancing, when I run benchmark from client to server. All clients nic bandwidth in eth0. I ifdown eth0, all bandwidth could move to eth1. When I remove HP brick(signle 10Gb port), Nic bond could load balancing. All client use native mode mount gluster server. cmd is "mount -t glusterfs HP-server-ip:/test-volume /mnt -o noatime" Now ,I add HP brick again , and I change the bond mode to IEEE 802.3ad Dynamic link aggregation. bond could load balancing too. 1 x HP 380 G6, nic: 1 x NetXen NX3031 , Dual port 10Gb, only single 10Gb port up(eth0). 3 x Dell R410, nic: 2 x Broadcom BCM5716, I create bond0 , bond mode is Adaptive load balancing.
