From the ctdb/doc/ctdb.1.xml man page file:

    <refsect2>
      <title>setlmasterrole on|off</title>
      <para>
        This command is used to enable/disable the LMASTER capability for a node at runtime. This capability determines whether or not a node can be used as an LM
      </para>

      <para>
        Nodes will by default have this capability, but it can be stripped off nodes by the setting in the sysconfig file or by using this command.
      </para>

So looks like setting the ctdb sysconfig file would be the
way to go. Hopefully Martin or Amitay can confirm and give
a more complete explaination.
