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/
Include the rdma port 2050 into this file as:
[root@host~]# echo rdma 2050 > /proc/fs/nfsd/portlist
vi. Run
exportfs
to make local directories available for Network File System (NFS) clients to
mount.
[root@host~]# exportfs
Now the NFS-RDMA server is ready.
Client-side settings

i. Load the iwarp modules and make sure peer2peer is set to 1. Make sure you are able to
ping and ssh to the server Chelsio interface through which directories will be exported.
