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.
Gluster use IPoIB as mentioned by Deepak. So qperf with default options may not be a good choice to test IPoIB. Because it will fallback to any link available between the mentioned server and client. You can force this behavior, please refer the link [1]. In addition to that, Can you please provide your gluster version, glusterd logs and brick logs. Because since it complains about absence of the device, mostly it could be a set up issue. Otherwise it could have been a permission denied error, I'm not completely ruling out the possibility of selinux preventing the creation if IB channel. We had this issue in rhel which is fixed in 7.2 [2] . [1] : https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/htm...

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 ?
