My understanding is that @transport argumet in<br>

Can someone correct me ?<br>

Have we ever supported volfile fetch over rdma ?<br></blockquote><div> </div></span><div>I think no. To test, you would have to set rdma as only transport option in glusterd.vol and see what happens in volfile fetch. </div><div><br></div><div><br></div><div>IMO, fetching volfile over rdma is an overkill and would not be required.</div><div>RDMA should be kept only for IO operations.</div></div></div></div></blockquote><div><br></div><div style="">+1.
