Lets take this one step at a time, starting with this issue.
First, there is a reason why a simple create_ctrl fails, can we isolate
exactly which call fails? Was something else going on that might have
made the simple create_ctrl fail?
We don't see any "rdma_resolve_addr failed" or "failed to connect queue"
messages but we do see "creating I/O queues" which means that we either
failed at IO tagset allocation or initializing connect_q.
We have a missing error code assignment so can you try the following
patch:
Hi Sagi
Sorry for the late response, here is the log with your patch, let me
know if you need more test.
