What bonding mode do you have on your cluster? I tried mode 5 and 6, and I got some dropped packets, then I switched to mode1, and still got dropped packets. Here is modprobe.conf:
alias bond0 bonding #options bond0 mode=5 miimon=100 use_carrier=0 options bond0 mode=1 miimon=100 use_carrier=0 alias eth0 bnx2 #alias eth1 bnx2 alias eth2 bnx2 #alias eth3 bnx2 alias scsi_hostadapter cciss alias scsi_hostadapter1 sata_svw alias scsi_hostadapter2 lpfc alias scsi_hostadapter3 usb-storage -- Alan A.
