Hi Christoph/Sagi/Martin,
We're encountered a crash while testing failover between NVMeF/RDMA
paths to a target that expose a namespace with metadata. The scenario is
the following:
Configure one initiator/host path on PI offload capable port (e.g ConnectX-5
device) and configure second initiator/host path on non PI offload capable
port (e.g ConnectX-3).
Hmm. I suspect the right thing to do here is to just fail the second
connect.
Yeah, I'm slightly unhappy with this whole setup.
If we were just doing DIF I guess the setup could work, but then we have
to disable DIX (as we cannot support integrity data on the non-PI path).
But we would need an additional patch to disable DIX functionality in
those cases.
Cheers,
Hannes
