Hi Soumya,
OK, that trick worked, but now I'm back to the same situation of the
hanging showmount -e. Did you check the logs I sent yesterday? Now I'm
essentially back to the situation of the fir log (ganesha.log.gz) in all
cases.
Thanks,
Alessandro

If I do the same after exporting a volume nfs-ganesha does not even start, complaining for not being able to bind the IPv6 ruota socket, but in fact there is nothing listening on IPv6, so it should not happen:
