RHEL 4.5 Bonding troubles

Star Dust — Sat, 22 Dec 2007 18:33:13 GMT

I'm posting this again...

I have two servers, each with 6 NIC cards in them. The first two NIC's are for metadata and the last 4 (eth2 through eth5) I want bonded. All cards use the bnx2 driver and I've tried the HP version and the standard Redhat version with no difference.

I think I have the server side and switch side configured correct, but I'd like someone opinion because it's not working right. When I try to ping or move files from one machine to another there is very high latency or they don't talk at all. I'm not sure what I'm doing wrong. Here are the configurations that I'm using as well as some output from the /var/log/messages file. Thanks for the help!

I'm going to have to go back into work and get my ifcfg-bon0 settings since my post was deleted last night, but it's pretty standard and when when I only had two NIC's bonded (which worked) it what I used. I also do have the "alias bond0 bonding" in my /etc/modprobe.conf file along with all the NIC cards.

are the NIC cards and the switches support 1000MBPS?(if yes you make sure that duplex is full and auto negotitaion is on at both sides.

If you are unsure what is configured at the switch side contact your netowrk team to confirm that.. I could not follow anyhting about the speed and duplex from what you posted under "switch settings"

from the messages file you posted it looks like auto negotiation is off and speed to got set to 100MBPS and dulex to full ... later it is reporting 1000 Mbps full duplex

could you post "ethtool ethx" for all where x is the respective cards

Shalom,

Bonding was really designed and tested for pairing two cards.

Though obviously possible to bond more than two, the results you receive may be due to one of the following factors:

problems in /etc/modprobe.conf # typo?
You are pushing the software beyond where the developers tested it.
Network switch/port settings prevent proper bonding. On cisco switches some assembly is required for bonding to work.

Thank you both for the responses. I've directly cut and copy my config files from my linux machines and from my switch as well as the ethtool outputs. I did notice that for some reason my eth5 card cannot be read. What would cause something like that to happen? It's the second port from a duel port NIC card.

for eth5 there is no link detected. Could be a cable not/loose connected or a defective cable itself.. verify from both server and switch side.
