Hi all,<br><br>I&#39;m trying to define a constraint like this:<br><br><br>cibadmin -o constraints -U -p&lt;&lt;END<br> &lt;rsc_location id=&quot;drbd-master&quot; rsc=&quot;ms-drbd&quot;&gt;<br>  &lt;rule id=&quot;diskless_constraint_evaluator&quot; score=&quot;-INFINITY&quot; role=&quot;master&quot; boolean-op=&quot;or&quot;&gt;<br>
   &lt;rule id=&quot;diskless_constraint_1&quot; boolean-op=&quot;and&quot;&gt;<br>         &lt;expression id=&quot;${node1}_expr_1&quot; value=&quot;${node1}&quot; attribute=&quot;#uname&quot; operation=&quot;eq&quot;/&gt;<br>         &lt;expression id=&quot;${node1}_expr_2&quot; attribute=&quot;master-drbd0:0&quot; operation=&quot;lt&quot; value=&quot;1000&quot;/&gt;<br>
    &lt;expression id=&quot;${node1}_expr3&quot; attribute=&quot;master-drbd0:0&quot; operation=&quot;not_defined&quot;/&gt;<br>  &lt;/rule&gt;<br>   &lt;rule id=&quot;diskless_constraint_2&quot; boolean-op=&quot;and&quot;&gt;<br>
         &lt;expression id=&quot;${node2}_expr_1&quot; value=&quot;${node2}&quot; attribute=&quot;#uname&quot; operation=&quot;eq&quot;/&gt;<br>         &lt;expression id=&quot;${node2}_expr_2&quot; attribute=&quot;master-drbd0:1&quot; operation=&quot;lt&quot; value=&quot;1000&quot;/&gt;<br>
         &lt;expression id=&quot;${node2}_expr3&quot; attribute=&quot;master-drbd0:1&quot; operation=&quot;not_defined&quot;/&gt;<br>  &lt;/rule&gt;<br> &lt;/rsc_location&gt;<br>END<br> <br><br>I&#39;m getting <br>Call cib_create failed (-47): Update does not conform to the configured schema/DTD<br>
<br> <br>Is it not possible to define constraints like these ?<div><br></div><div><br></div><div><br></div><div><br></div><div>Thanks</div><div>Shravan</div>
