[Lustre-discuss] Configuration of lustre FS on single node

Fri Feb 29 00:26:31 PST 2008

Ashok,

If you are trying to setup lustre (with all the servers MDS, OSS.. etc) 
building only the patchless client wont help you.

You will have to build lustre as described here : 
http://wiki.lustre.org/index.php?title=Lustre_Howto

thanks,
Amit.
