Mmm. 1.8 clients are not fully supported with 2.5 servers. I wouldn't expect a hang, but I'm not surprised NFS export is not working. (Again, stack traces of your NFSD threads on the Lustre client trying to act as an NFS server may be illuminating.)

Sorry, left off some important info...

the system is rhel5, with client 1.8.7... the lustre file system is 2.5.3 (the 
system already exports a 1.8.9 lustre file system).

Subject: Exporting a lustre mounted directory via nfs

Good Afternoon,

    I'm attempting to use nfs to export a lustre mount point on a client box 
(essentially acting as a gateway for systems that don't have the lustre 
client).  I've mounted lustre, and added it to the nfs exports file (it shows 
up as exported) but when I try to mount the nfs point the system hangs.  On the 
server side (the lustre gateway) I do see the test system authenticating.

w/r,
Kurt
