Ok, but that wasn't what I was suggesting.

I was suggesting:

 <rsc_colocation id="rsc_colocation01-3" rsc="UMgroup01"
with-rsc="clnUMgroup01" score="INFINITY"/>

<rsc_location id="no-connectivity-01-1" rsc="UMgroup01">
   <rule id="clnPingd-exclude-rule" score="-INFINITY" boolean-op="or">
      <expression id="UMgroup01-clnPingd-exclude" attribute="clnPingd"
operation="not_defined"/>
      <expression id="UMgroup01-clnPingd-only-positive"
attribute="clnPingd" operation="lt" type="integer" value="1"/>
      <expression id="UMgroup01-clnPingd2-exclude"
attribute="clnPingd2" operation="not_defined"/>
      <expression id="UMgroup01-clnPingd2-only-positive"
attribute="clnPingd2" operation="lt" type="integer" value="1"/>
   </rule>
</rsc_location>

<rsc_location id="no-connectivity-02-1" rsc="group02-1">
   <rule idref="clnPingd-exclude-rule"/>
</rsc_location>

<rsc_location id="no-connectivity-02-1" rsc="group02-2">
   <rule idref="clnPingd-exclude-rule"/>
</rsc_location>
