Hello,

I'm configuring the cib.xml for heartbeat2/drbd/mysql.
With the following xml file, it wokrs.

hostname: h1/h2

However, automatic failback happens.

I guess it is because of this part;
         <rule id="prefered_location_group_1" score="100">
           <expression attribute="#uname"
id="prefered_location_group_1_expr" operation="eq" value="h1"/>
         </rule>


It is OK if two nodes are online, pick h1 for that resource.
However, I don't want to failback from h2 to h1, after repairing h1.

Anyone suggeest which part I should change?
