rdma: Wrong volfile fetch on fuse mounting tcp,rdma volume via rdma
As of now for both tcp only volumes and rdma only volumes, volfile names are in the format <volname>-fuse.vol. This patch will change the client volfile namings as shown below. * TCP mounts always use <volname>-fuse.vol * RDMA mounts always use <volname>.rdma-fuse.vol Following the above naming convention, for tcp,rdma volumes both volfiles will be present under /var/lib/glusterd/vols/<volname>/ such that rdma only volume can be mounted as mount -t glusterfs -o transport=rdma <server/ip>:/<volname> <mount-point> OR mount -t glusterfs <server/ip>:/<volname>.rdma <mount-point> The above command format can also be used to fuse mount a tcp,rdma volume via rdma transport. When we try to fuse mount a tcp,rdma volume with transport-type as rdma it silently mounts via tcp. This change will also make sure that it fetches the correct volfile based on the transport-type specified from client side.
