True, it is a pain, but I think it's realistic to expect someone who wants to do pnfs to have an updated nfs-utils. It wouldn't take too long for it to trickle out to the various distros and adding new export options is fairly simple to do. If we do want to go that route, it might be nice to do the option with a list of layout types. For example: pnfs=block:file:flexfiles ...so we could potentially support more than one layout type per export. -- Jeff Layton _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
