Configuring NFS-RDMA
NFS-RDMA for iWARP includes both server and client configuration steps.
To configure the NFS server:
1.
In the
/etc/exports
file for the directories that you must export using
NFS-RDMA on the server, make the following entry:
/tmp/nfs-server *(fsid=0,async,insecure,no_root_squash)
Ensure that you use a different file system identification (FSID) for each
directory that you export.
2.
Load the svcrdma module as follows:
#
modprobe svcrdma
3.
Start the NFS service without any errors:
#
service nfs start
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
