Problem with NFS Over RDMA on OmniPath

I have been trying to setup NFS over RDMA on OmniPath following instruction in official document. IPoIB works fine, but I cannot get NFS over RDMA working. I have modified /etc/rdma/rdma.conf and added NFSoRDMA_LOAD=yes NFSoRDMA_PORT=2050 I have also loaded appropriate modules ( sunrpc on the client, xprtrdma on the server). However, the NFS mount fails (connection refused) when using RDMA to mount, note that it works fine if I do not specify rdma. It appears that the 2050 port for NFSoRDMA does not get created, when I do rpcinfo from the client to examine the server I see ports 2049 for nfs, but nothing for 2050. This is on CentOS 7.4. Any ideas/suggestions what may be wrong?

I think I have solved the problem:

I had to execute the following (in addition to the official instructions) to make this work:

rdma 2050 > /proc/fs/nfsd/portlist

This is on CentOS 7.4
