hello!
    I am trying to configure NFS/RDMA for our infiniband network, and
following the instructions at nfs-rdma.txt.
    I installed the MLNX_OFED drivers on CentOS 7.5.
    I tested  infiniband network with tools like udaddy and
rdma_server/rdma_client and everything is fine.
    But when I execute "echo rdma 20049 > /proc/fs/nfsd/portlist",
show "-bash: echo: write error: Protocol not supported".
    I have searched a lot of information on Google and can't solve
this problem. I hope you can give me some help.
thank you very much=EF=BC=81

My test:
the server:
[rooot@w29 ~]# udaddy
the client:
[rooot@w28 ~]# udaddy -s 192.168.145.29
udaddy: starting client
udaddy: connecting
initiating data transfers
receiving data transfers
data transfers complete
test complete
return status 0

and the rdma_server/rdma_client
the client:
[rooot@w28 ~]#rdma_client -s 192.168.145.29
rdma_client: start
rdma_client: end 0
