Description of problem:

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

+------------------------------------------------------------------------------+
[2014-12-08 22:18:56.669319] W [rdma.c:1082:gf_rdma_cm_event_handler] 0-testvol-client-3: cma event RDMA_CM_EVENT_ADDR_ERROR, error -19 (me: peer

[2014-12-08 22:18:56.684545] I [fuse-bridge.c:5561:fini] 0-fuse: Unmounting '/gluster-mount'.

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.
