Exporting a lustre FS via NFS

I'm trying to export a lustre FS via NFS, but I keep getting "permission 
denied" when I try to mount them on the client.  If I export the parent 
directory, I can access the parent directory, but the lustre FSes are 
empty.  This behavior happens on both Linux and Solaris clients.

I've done several searches and learned this was a problem in Lustre 1.2. 
 But haven't seen any mention of it since then.

Thanks for your help.
