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.
