I'm not aware of any plans to integrate the new v4 stuff into our cluster product.

That would be an extremely attractive thing with something like GFS on the backend. -- Jeff Layton _______________________________________________ NFSv4 mailing list NFSv4@linux-nfs.org http://linux-nfs.org/cgi-bin/mailman/listinfo/nfsv4
