[ClusterLabs] pacemaker alerts node_selector

[vockinger at gmail.com]

Hi, thank you for your reply.

I tried it this way:

    <alerts>
      <alert id="test_alert_avzone_1" path="/usr/share/pacemaker/alerts/test_alert.sh">
	  <select>
	  	<select_nodes>hana_node_1</select_nodes>	  
	  </select>
        <instance_attributes id="test_alert_1-instance_attributes">
          <nvpair name="HANASID" value="XAI" id="test_alert_1-instance_attributes-HANASID"/>
          <nvpair name="AVZone" value="AV1" id="test_alert_1-instance_attributes-AVZone"/>
        </instance_attributes>
        <recipient id="test_alert_avzone_1-recipient-1" value="/usr/share/pacemaker/alerts/test_alert.sh"/>
      </alert>
      <alert id="show" path="test_alert_avzone_1"/>
    </alerts>


During the save the select is been reset to 
  <select>
	  <select_nodes / >	 
 </select>


Do I need to specify in addition to select_nodes the section <element name="select_attributes">

Thank you, Alfred

What version of Pacemaker are you using, and how does it behave?

Depending on the error/misbehavior you're experiencing, this might have been me. Looks like in commit bd451763[1], I copied the alerts-2.9.rng[2] schema instead of the alerts-2.10.rng[3] schema.

[2] https://github.com/ClusterLabs/pacemaker/blob/master/xml/alerts-2.9.rng
[3] https://github.com/ClusterLabs/pacemaker/blob/master/xml/alerts-2.10.rng
