Not all NFSv4 errors are sent back to userspace, and the meaning of this
error ( I am assuming the server returns NFS4ERR_BADOWNER, a wire
capture
would verify it ) is to tell the client that it was unable to translate
the
owner value. As I understand RFC 8881, that's a clear indication to the
client that the server is not treating the values as numeric uid/gid, it
is
attempting to map them. That is why the client changes its behavior.
Besides, what error can the chown syscall possibly return in this case?
Let's say the client /doesn't/ re-enable string-based names. What are
you
expecting the client to return to userspace?
