[Lustre-discuss] NFS Export Issues

Without more information about the server error messages and exact nfs 
configuration, not sure anyone can help more than this.  A common 
problem with Lustre NFS exports, one that isn't due to normal 
NFS/configuration issues, is getting error -43 when the mds did not have 
the client's IDs in its /etc/passwd and /etc/group files.

Dumb question, but have you checked the permissions on the NFS server's 
Lustre mount point (before/after Lustre is mounted), and exported a 
non-Lustre directory successfully?
