Hi all,
I'm used to create a mode 4 bond0 interface with two 1 Gb/s interfaces on all my hosts, and ethtool bond0 gives me a functionnal 2000Mb/s. However, when importing a vm from the export domain (NFS with a speed of 4GB/s), I always have this alert: "Host siple has network interface which exceeded the defined threshold [95%] (em3: transmit rate[0%], receive rate [100%])" It seems that the second nic never works while the first one is overloaded. Is it an expected behaviour? I believed that the flow was balanced between the two interfaces in 802.3ad mode.
