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?
