I did some checks of this feature. The gluster CLI accepts the new
combined transport option:

# gluster volume create space transport tcp,rdma server:/brick
# gluster volume start space

Afterwards I'm able to mount the volume using the defaults which results
in a mount over TCP. But I was not able to mount it using RDMA. I tried
the appropriate option in the mount command:

# mount -t glusterfs -o transport=rdma server:/space /space

This results in a mount using TCP.

Forcing a mount using the "old way" didn't succeed either. I copied the
generated space-fuse.vol, changed the transport to RDMA and mounted it
manually:

# mount -t glusterfs /etc/glusterd/vols/space/space-rdma-fuse.vol /space

Once I saw an error that the client used a wrong protocol, usually it
simply reports a connection and a disconnection.

Looks like you have some work in the server and client area.

At least NFS looks now stable, so I'm currently mounting the Gluster
servers on Ethernet only nodes by using NFS.
