4.3.1. Starting NFS-RDMA

Server-side settings

Follow the steps mentioned below to set up an NFS-RDMA server.

i. Make entry in /etc/exports file for the directories you need to export using NFS-RDMA on

server as:

/share/rdma *(fsid=0,async,insecure,no_root_squash)

/share/rdma1 *(fsid=1,async,insecure,no_root_squash)

Note that for each directory you export, you should have DIFFERENT fsid’s.

ii. Load the iwarp modules and make sure peer2peer is set to 1.

iii. Load xprtrdma and svcrdma modules as:

[root@host]# modprobe xprtrdma

[root@host]# modprobe svcrdma

iv. Start the nfs service as:

[root@host]# service nfs start

All services in NFS should start without errors.

v. Now we need to edit the file portlist in the path /proc/fs/nfsd/

vi. Include the rdma port 2050 into this file as:

[root@host]# echo rdma 2050 > /proc/fs/nfsd/portlist
