[ewg] Ofed1.3 bonding problem

[Acero Fernandez Alicia]

Hi everybody,
 
I have tried what is explained in the ib-bonding.txt file, but it doesn't work. What are the lines in the /etc/modprobe.conf for Redhat Enterprise linux 4 up 5? Or perhaps there is some more information needed.
 
Could anyone help me?
 
Regards
Alicia

Hi Alicia,

You are right bonding package inside OFED replaces bonding package

that is installed on your OS (ib-bonding is installed under

/lib/modules/<uname -r>/updates, therefore if you will remove it, you

will have native bonding working).

I assume that your OS is RH 4.

Indeed in OFED 1.3 there was a bug, that Ethernet bonding didn't work

on RH4, but there is a workaround in OFED 1.3.1.

ib-bonding rpm includes ib-bonding.txt file that has an instruction

how to configure Ethernet bonding:

(/usr/share/doc/packages/ib-bonding-0.9.0/ib-bonding.txt)

3.3 Configuring Ethernet slaves

-------------------------------

It is not possible to have a mix of Ethernet slaves and IPoIB slaves under the

same bonding master. It is possible however that a bonding master of Ethernet

slaves and a bonding master of IPoIB slaves will co-exist in one machine.

To configure Ethernet slaves under a bonding master use the same instructions

as for IPoIB slaves (according  to the OS) with one exception. When working

under Redhat-AS4 do the following when configuring a bonding  master with

Ethernet slaves

- In the master configuration file add the line

SLAVEDEV=1

- In the slave configuration file leave the line

TYPE=InfiniBand

This bug will be fixed in OFED 1.4.

Please let me know if it helps.

Best Regards

Olga

Hi everybody,


I am trying to install ofed1.3 in my cluster. I have done ethernet

bonding in some network interfaces and I would like to install

ofed1.3, but when I try it ethernet network connection is lost. I have

been looking for a solution, but I have found that the module name for

ethernet bonding and for infiniband bonding is the same, then perhaps

it is the reason, is it true? In that case, how could I solve it? It

doesn´t seem to be solved in ofed1.3.1 because I have tried to install

it and the same happens.

Could you help me, please?

Regards
