[Gluster-users] "tcp connect to failed" messages

I'm running GlusterFS 3.3.1-ubuntu1~precise9 and I'm having some problems with the "rdma" and "tcp,rdma" options I hope someone can help me with.
1. What does "tcp,rdma" actually do - does it let you mix both types of client? (I did a few tests with iozone and found it gave identical performance to the "tcp".)
2. I can't get "rdma" to work, even in the simplest case with a single node.
volume create storage transport transport rdma my_server:/data/area
volume start storage
mount -t glusterfs my_server:storage /mnt/storage
The last line hangs. Looking in /var/log/glusterfs I can see the log for the volume:
[2013-05-30 06:24:19.605315] E [rdma.c:4604:tcp_connect_finish] 0-storage-client-0: tcp connect to failed (Connection refused)

This block repeats every few seconds - the line "tcp connect to failed" looks like it has lost the server name somehow?
