I think you have wrong command. Your testing TCP & not RDMA. Also check if you have RDMA & IB modules loaded on your hosts.

Read qperf man pages for more info.

Dear Deepak, thank you for the hints, which gluster are you using?
As you can see from my previous email that the RDMA connection tested with qperf. It is working as expected. In my case the clients are servers as well, they are hosts for the ovirt. Disabling selinux is nor recommended by ovirt, but i will give a try.

I have been testing glusterfs over RDMA & below is the command I use. Reading up the logs, it looks like your IB(InfiniBand) device is not being initialized. I am not sure if u have an issue on the client IB or the storage server IB. Also have you configured ur IB devices correctly. I am using IPoIB.
Can you check your firewall, disable selinux, I think, you might have checked it already ?
mount -t glusterfs -o transport=rdma storageN1:/vol0 /mnt/vol0
· The below error seems if you have issue starting your volume. I had issue, when my transport was set to tcp,rdma. I had to force start my volume. If I had set it only to tcp on the volume, the volume would start easily.
