      <para>

        This command changes the role of the node. Each options takes

        either a literal <literal>yes</literal> or

        <literal>no</literal>, and only one option should be given as

        <literal>yes</literal>. The meaning of the roles are described

        in the manpage <citerefentry>

        <refentrytitle>ganeti</refentrytitle> <manvolnum>7</manvolnum>

        </citerefentry>.

      <para>

        In case a node is demoted from the master candidate role, but

        there are not enough new nodes for this case, the operation

        will be refused. To override this check, pass the

        <option>--force</option> option.

        Example (setting a node offline, which will demote it from

        master candidate role if is in that role):

        <screen>

# gnt-node modify --offline=yes node1.example.com

        </screen>

      </para>

      <para>Example (setting the node back to online and master candidate):

        <screen>

# gnt-node modify --offline=no --master-candidate=yes node1.example.com

        </screen>
