Strange bug within UEK6 and bonding of 2 Broadcom Networkcards

Hello there,

I am new in this community and i am not sure, if this is the right place to ask my question, but I try:

We are using OLVM with Oracle Linux 7.9 UEK6 on Dell Servers with two Broadcom 57412 10GB/s cards.

In the beginning, everything went well. To secure our availability, we wanted to bond the two networkcards. It turns out, that is not possible with UEK6. If we bond the two ports on the same card, everything works fine. But it fails, if we bond the two ports of different cards.

We have a workaround with installing Oracle Linux 7.8 with UEK5. Here it is working fine. After updating it, we have OL7.9 but without Kernel Upgrade, so still using UEK5. That is working perfectly fine.

This issue sounds exactly like this issue in RedHat Enterprise Linux:

access.redhat.com/solutions/5642221

The same problem is reported in another environment (proxmox):

forum.proxmox.com/threads/network-problem-bond-vlan-bridge.70875/

Does anybody know, how to address this issue to the right people? We do not have OLVM support, but it is more a bug report, than a support case, so I think, it makes no sense to purchase support for this problem?


Many thanks for some help or guideance,

Paul

    We are queueing the fix up for a future UEK6 5.4.17-2036.* build (and in fact that change is already in queue for the next UEK6 branch, aka UEK6 U2). Be on the lookout for this entry in a new UEK6 RPM changelog:

    net: Fix bridge enslavement failure

    Thank you for the report!

    Hi,

    which logs do you need?

    We are running with the workaround at the moment. But we have another server, we can test with. But that will take some time to prepare.

    So, can you tell me, which logs are needed for further investigation?

    Regards,

    Paul

    Hi.

    I am not Oracle's engineer and can not help open BUG, but just for other engineer can reproduce or clear this problem:

    What version of kernel You are use ? ( uname -a)

    Which type of bonding was configured ? ( Provide configuration).

    Do You use VLANs ?

    You say that bonding is fail on ports from different cards

    -What exactly fail? Do You have some warning or error messages ?

    ( Part of /var/log/messages about network and bond )


    Regards,

    Nik
