I haven't set this up, but most options like "nfsrdma=y" are entered
into the ofed.conf file that is generated when building OFED, usually
locate just inside the OFED dir. Once you have that file, you can just
run ./install.pl -c ofed.conf. If you don't have one there, you might
be able to generate it by building some or all of the OFED stack.<br>

easiest steps to have nfsrdma up and running:

Download OFED-1.4.1-rc1 from

<br>
and build/install nfsrdma. It is running on 2.6.27/26/25 and RHEL 5.2
default kernels
<br>
<br>
Or
<br>
+ Download kernel 2.6.27 from kernel.org
<br>
+ Build the kernel 2.6.27 with IB driver (and other modules ie.
user_mad, addr_trans, ib_mthca, mlx4_ib... ), nfs client/server,
sunrpc... as modules
<br>
+ Boot up with new kernel
<br>
+ Follow the attached README
<br>
<br>
NOTE: You can also download and run nfsrdma on latest development
kernel 2.6.29-rc7; however, it does not work on Mellanox ConnectX HCA
due to a bug on Fast memory registration work request. We are debugging
it now

Hello,
<br>
<br>
I want to try NFS over RDMA. According to the documentation enclosed
<br>
within the OFED-1.4 release, it should be as simple as setting
"nfsrdma=y".
<br>
<br>
Unfortunately there is no such option. The interactive menu offered by
<br>
'./install.pl' does not mention NFS neither.
<br>
<br>
Is there an updated version of the documentation on how to run NFS over
<br>
RDMA? I have noticed, that it is part of the vanilla Linux kernel but I
still did
<br>
not manage to get it up and running.
<br>
<br>
Many thanks for your advice,
<br>
Philip
