Did you check your connection with iperf and iperf3 in TCP bandwidth? in that case, these tools cannot find out packet drops.
Try checking out your block device backend responsibility with benchmark tools like vdbench or bonnie++. Sometimes bad block device causes incorrect data transfer.

Subject: [lustre-discuss] lustre causing dropped packets
I have a small setup I am testing (1 MGS, 2 OSS) that is connected via
I notice that when I run anything that writes to the lustre filesystem
causes dropped packets. Reads do not seem to cause this. I have also
tested the network (iperf, iperf3, general traffic) with no dropped packets.
Is there something with writes that can cause dropped packets?
