CatOS, bonded channels and non-bonded servers

Posted on by

It came to my attention today that when a Catalyst running CatOS reports

Port  Status     Channel   Channel     Neighbor                  Neighbor
                 mode      status      device                    port
----- ---------- --------- ----------- ------------------------- ----------
8/7  connected   on        channel
8/8  connected   on        channel

it means the two ports are bonded together.  This poses distinct problems when the server isn’t aware that the two connections are bonded.  A CentOS installation process that takes 5 minutes normally was still running 3 hours later, and it wasn’t even half-way.  What was even more interesting was that the repository server showed files being downloaded, but Anaconda swore blind that nothing was happening.

Live and learn.

  1. even more fun when you’ve got LACP turned on with the bonding driver. strange doesn’t even begin to describe the behavior.
