Thanks a lot,.... Unfortunately, we are using IPoIB with IPv6 in
production for the inter-VM and the internet gateway traffic. We had an
issue last Friday were one of our gateway machines wasn't reachable
anymore and pings didn't come through. We had to reload the ib_ipoib
modules of nearly every server connected to that gateway. I'm so glad
that we use SRP - all SRP connections survived.
I don't have the time to care for IPoIB as well at ProfitBricks so I
will encourage our networking teams to get their hands on IPoIB and
linux-rdma communication.
How to verify if we've hit this bug? How to reproduce this bug?
Cheers,
Sebastian
