Hi,
I have exactly the same problem. I am looking for solution that let
me export lustre file system without having to specify fsid= in
export options.
I have found in bugzilla bug 10786 that apparently resolves that
problem. Unfortunately I can't find if this patch is available for
1.6.0.1
I also don't know how to apply patch in the following format please
could some one give me some small how-to on that?

I had just done this with 1.4 and had the same problem. You need to
add the "fsid=13" to the export options for /etc/exports. That
makes NFS think that they are exporting a native unix file system.
They don't like to re-export shared file systems by default.

I'm running Lustre version 1.6.0.1 and I'm trying to export lustre

wonder if
anyone can help with step-by-step or point me to where the problem
should
be. I'm really appreciated.
