FW: [ewg] Ofed1.3 bonding problem

[Olga Shern]

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
