[ofa-general] ***SPAM*** Re: IB Bonding errors with recent kernel

[Dennis Portello]

I can confirm that this issue exists beyond Redhat 4, I'm using Ubuntu 8.10
(2.6.27).

I'm using ib-bond and I've also tried adding he bonds directly with

echo +bond0 > /sys/class/net/bonding_masters
echo 1 > /sys/class/net/bond0/bonding/mode
echo 100 > /sys/class/net/bond0/bonding/miimon
echo +ib0 > /sys/class/net/bond0/bonding/slaves
echo +ib1 > /sys/class/net/bond0/bonding/slaves
ifconfig bond0 192.168.47.102/24
route add -net 224.0.0.0/3 gw 192.168.47.100

I will be happy to open a ticket on this issue.

Thank you,
Dennis P.
