Hi Tom,

"./nfsrdmamount -o rdma on16-ib:/mnt/rdma /mnt/rdma" command never
returned. and the dmesg for client and server are:

------dmesg from server ------
nfsd: request from insecure port 140.221.134.220, port=32768!
svc_rdma_recvfrom: transport ffff81007e8f2800 is closing

Did I forget to configure necessary components into my kernel?

Thanks,
Helen
