+++ This bug was initially created as a clone of Bug #1173734 +++

Description of problem:

When I try to mount an RDMA volume without an IB interface I get the following
logs:

+------------------------------------------------------------------------------+

Is there any way we can make the error:

cma event RDMA_CM_EVENT_ADDR_ERROR, error -19

More descriptive so the user knows that there is an issue finding / connecting
with an RDMA device?

Version-Release number of selected component (if applicable):

glusterfs-3.6.0.38-1.el6.x86_64

How reproducible:

Every time

Steps to Reproduce:
1.  Try to mount an RDMA volume without a properly configured IB device.
2.
3.

Actual results:

Mount fails as expected, but log message is cryptic.

Expected results:

A more clear log message.
