I tried the crm_resource command, but it adds a permament location
constraint to the CIB. I was trying to avoid that.
For example, with a resource named IPaddr2_1, when I ran that command I
had this constraint added to my CIB:
<constraints>
<rsc_location id="cli-prefer-IPaddr2_1" rsc="IPaddr2_1">
<rule id="cli-prefer-rule-IPaddr2_1" score="INFINITY">
<expression id="cli-prefer-expr-IPaddr2_1" attribute="#uname"
operation="eq" value="cmlab8" type="string"/>
</rule>
</rsc_location>
</constraints>
crm_standby also adds a permanent instance attribute forcing the node to
standby until the attribute is deleted or set to false.

I don't want an INFINITY-scored location constraint to be added into the
CIB. I'd just like the resource to migrate if it's within the stickness
threshold.
Is such a thing possible?
Thanks,
Eric
