[lustre-discuss] lnet_selftest - fails for me

[Pinkesh Valdria]

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

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

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

 

Hello,  

 

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="10.0.3.4 at tcp1"   is the client node where I am running this script. 

LTO="10.0.3.6 at tcp1"   is one of the OSS server.    I have total 3 of them.
