Keep in mind that mpath table is going to empty unless you try to reach another node. Assuming your routing is correct, pinging from one node to another should initiate ARP request, which will cause path requests to go out and, ultimately, add entries to mpath table. I didn't see any mention of attempting to send data packets across the mesh, so that might be the only problem.
