Hello,
I have a question about resource_stickiness.
This value can be set as default, or primitive, instance_attributes, etc...
How priority is established?
I thought the order might be, primitive > instance_attributes > default,
but it seems that the value for primitive does something strange.
I set resource_stickiness = 0 as default like this; (a detail is attached)
------------------------------------------------------------------------
<cib>
<configuration>
<crm_config>
<cluster_property_set id="cluster">
<attributes>
<nvpair id="default" name="default-resource-stickiness" value="0"/>
...
</attributes>
</cluster_property_set>
</crm_config>
<nodes/>
<resources>
<group id="grpDummy">
<primitive id="prmDummy" class="ocf" type="Dummy" provider="heartbeat">
...
</primitive>
</group>
...
------------------------------------------------------------------------
I moved a resource, first;
(1)# crm_resource -r prmDummy -p resource_stickiness -v -INFINITY
It worked. The resource moved to the other node.
I brought resource_stickiness back to "0", and changed its value for
primitive tag, next.
(2)# crm_resource -r prmDummy -p resource_stickiness -v 0
(3)# cibadmin -U -X '<primitive id="prmDummy" class="ocf" type="Dummy"
provider="heartbeat" resource_stickiness="0"/>'
After that, I tried to move the resource again;
(4)# crm_resource -r prmDummy -p resource_stickiness -v -INFINITY
the resource kept running on the same node...
Is it expected?
Should meta_attributes be also considered?
I expected that the operation (3) was not change anything, so the resource
would be moved.
The version I have is v2.0.8.
Thanks,
Junko
