What I am seeing: 1. On Linux NFS client (2.6.29-rc2), issue chown(1) to change the owner of the file (causing SETATTR:OWNER to be issued) 2. My userland NFS server returns NFS4ERR_DENIED for the SETATTR op 3. Linux NFS client returns EIO (I/O error) to userland That was a bit unexpected. I would have guessed EPERM, perhaps.
