Figured out the issue.   I forgot to load module on the server side.  


Solution:   Load module on all nodes involved in testing.  


[root at lustre-oss-server-nic0-1 ~]# modprobe lnet_selftest

Subject: [lustre-discuss] lnet_selftest - fails for me




Does anyone know why this simple lnet_selftest is failing.    I am able to use the Lustre file system without any problem.    I looked at /var/log/messages on the client and server node and there are no errors.     Googling for the error,  was not helpful. 




The script:  lnet_selftest_wrapper.sh. has content which is mentioned on this page:  http://wiki.lustre.org/LNET_Selftest  (wrapper script at the end of the page). 


LFROM=" at tcp1"   is the client node where I am running this script. 

LTO=" at tcp1"   is one of the OSS server.    I have total 3 of them.
