--- Comment #5 from nchilaka <nchilaka at redhat.com> ---
I ran the steps which caused the bug, and found that it is fixed.Hence moving
to verified
Steps:
1)identified machines to be used for server and clients which have rdma cards.
  Also, I installed gluster-devel and gluster-devel-api packages on client and
server.
2)enabled RDMA on both server and client using
http://fpaste.org/245970/73750811/
3)create a volume with one-brick with transport type as RDMA and started it.
For the brick i had used RDMA IP
4)now copied the c program gfapi_perf_test.c to the client(avaialble on the
parent bug, from which this bug was cloned)
5.Compile the above C program that uses libgfapi
gcc -pthread -g -O0  -Wall --pedantic -o gfapi_perf_test -I
/usr/include/glusterfs/api gfapi_perf_test.c  -lgfapi -lrt

6. Do the following exports by issuing the command on cli of client as it is:
export GFAPI_HOSTNAME=<server ip>(rdma IP of the server node)
export GFAPI_TRANSPORT=rdma
export GFAPI_VOLNAME=<volume name>

7. Create a directory "tmp" under /mnt as the program requires this directory
8.Run the compiled output as
GFAPI_FILES=1 GFAPI_RECSZ=1024 GFAPI_FSZ=1048576 ./gfapi_perf_test

9. Mount the volume to see that files are created by the c program under
/mnt/tmp
Behavior before the bug was fixed:
===================================
Segmentation fault (core dumped)

Fixed behavior:
==============
Program executes successfully.



Version of test where QA found the issue fixed:
