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.
