Configuring NFS-RDMA
NFS-RDMA for iWARP includes both server and client configuration steps.
To configure the NFS server:
1.
Create an
nfs-server
directory and grant permission by issuing the
following commands:
#
mkdir /tmp/nfs-server
#
chmod 777 /tmp/nfs-server
2.
In the
/etc/exports
file for the directories that you must export using
NFS-RDMA on the server, make the following entry:
NOTE
For latency applications (send/write), if the perftest version is the latest (for
example,
perftest-3.0-0.21.g21dc344.x86_64.rpm
), use the supported
inline size value:
0-128
.
