By the way, are there any plans for the Linux NFS server to implement the file, flexfile and object layout? The object layout type has been deprecated, IIRC. Support for that type was removed from the Linux NFS client years ago. No support for it in the server is planned. The file layout type generally needs a cluster file system on the back end. You could build something over Ceph or gfs2, but it would be a significant effort and would need user demand. Currently there isn't any. The NFS server has a toy flexfile layout implementation which is not much more than a proof of concept. We do have an unscoped to-do to look at building that out to provide a platform for testing the client's flexfile support. That effort is not a high priority. -- Chuck Lever
