how upgrade linux bonding driver ?

Antonio Cardoso_1 — Fri, 27 Feb 2009 16:36:54 GMT

I have a ML350 systems using the channel bonding driver on RHEL4 OS. The driver release is 2.6.x on RHEL4.
I would like to get a more recent release to take benefit from latest fixes and improvements.
Is there a way to upgrade the driver, or is the upgrade to RHEL5 mandatory ?

thanks much.

As it is a kernel module, probably your best option is to upgrade your kernel.

Short of back-porting the changes to your RHEL4 kernel sources, I suspect that not only is upgrading the best option, it is the only option.

Bonfing driver in RHEL4 kernel is pretty stable, AFAIK.
Do you have some spceific issues?

BTW, did you already with the latest RHEL4 update level?

We are using the latest RHEL4 release (update 7), with kernel 2.6.9.78 and bonding driver 2.6.3.

We are looking how to upgrade this driver because, as stated in http://switch.dl.sourceforge.net/sourceforge/bonding/bonding.txt, "Starting with version 3.0.2, the bonding driver has logic to
suppress duplicate packets".
And we want a fix for this "duplicated packets" issue, that can be observed in some specific network configurations.

I see.
So the only supported by RH option is upgrading to RHEL5.

For sure it is possible technically to upgrade the kernel and/or compile custom kernel with the new driver, but we'll get unsupported system in this way.
