Hello All,
I'm trying configure solution where one resource will be able know where is the
second located.
I have configured one easy resource
<primitive id="rs_ip_s2s" class="ocf" type="IPaddr" provider="heartbeat">
<instance_attributes id="special-node1" score="5">
<rule id="node1-special-case" score="INFINITY" >
<expression id="node1-special-case-expr"
attribute="#uname" operation="eq" value="node1"/>
</rule>
<nvpair id="node1-special-case-rule_co" name="rule_co"
value="1"/>
</instance_attributes>
<instance_attributes id="special-node2" score="4" >
<rule id="node2-special-case" score="INFINITY">
<expression id="node2-special-case-expr"
attribute="#uname" operation="eq" value="node2"/>
</rule>
<nvpair id="node2-special-case-rule_co" name="rule_co"
value="2"/>
</instance_attributes>
<instance_attributes id="special-node3" score="3">
<rule id="node3-special-case" score="INFINITY" >
<expression id="node3-special-case-expr"
attribute="#uname" operation="eq" value="node3"/>
</rule>
<nvpair id="node3-special-case-rule_co" name="rule_co"
value="3"/>
</instance_attributes>
<instance_attributes id="special-node4" score="2" >
<rule id="node4-special-case" score="INFINITY">
<expression id="node4-special-case-expr"
attribute="#uname" operation="eq" value="node4"/>
</rule>
<nvpair id="node4-special-case-rule_co" name="rule_co"
value="4"/>
</instance_attributes>
<instance_attributes id="defaults" score="1" >
<nvpair id="rs_ip_s2s-instance_attributes-ip" name="ip"
value="10.226.130.48"/>
</instance_attributes>
</primitive>
But problem is that attribute rule_co isn't globally visible for another
resources, I have location rule for second resource
<rsc_location id="M_Master2" rsc="rs_ip_usr">
<rule id="M_Master2-rule" boolean-op="and" score="-INFINITY">
<rule id="M_Master2-rule1" boolean-op="or" score="1">
<expression attribute="#uname" id="M_test2-1"
operation="eq" value="node1"/>
<expression attribute="#uname" id="M_test2-2"
operation="eq" value="node2"/>
</rule>
<rule id="M_Master2-rule2" boolean-op="or" score="2">
<expression attribute="rule_co" id="test-31"
operation="eq" value="3"/>
<expression attribute="rule_co" id="test-32"
operation="eq" value="4"/>
</rule>
</rule>
</rsc_location>
<rsc_location id="M_Master" rsc="rs_ip_usr">
<rule id="M_Master-rule" boolean-op="and" score="-INFINITY">
<rule id="M_Master-rule1" boolean-op="or" score="1">
<expression attribute="#uname" id="M_test-1"
operation="eq" value="node3"/>
<expression attribute="#uname" id="M_test-2"
operation="eq" value="node4"/>
</rule>
<rule id="M_Master-rule2" boolean-op="or" score="2">
<expression attribute="rule_co" id="test-21"
operation="eq" value="2"/>
<expression attribute="rule_co" id="test-22"
operation="eq" value="1"/>
</rule>
</rule>
</rsc_location>
But it can't see attribute "rule_co". Is there way how to get the value from
the rule_co like rs_ip_s2s.rule_co, or define some global attribute which will
be visible for all ?
I'm trying configure situation that the second resource will be able run only
on two nodes which are in the same DC where is running resource1
Thanks
Jozef
