All,
I am currently running heartbeat 2.0.8 (plans to upgrade are in the
works). I have a group of similar processes, currently configured as
ordered="true" and collocated="true", with the attributes within the
group tag in the XML. I have a group constraint to set the preferred
node for the group. I modified the ordered attribute of the group tag
from "true" to "false", leaving the collocated attribute set to "true".
When I do that, the processes all start up asynchronously, as expected,
but the processes are no longer collocated (in fact they evenly
distribute between the two systems, 5 one one, 4 on the other). Am I
mis-interpreting the ordered attribute? I saw in the online examples
that collocation there is done via an rsc_colocation constraint. Are
these two different ways of enforcing collocation? The group definition
and constraint are shown below. If more information is needed please let
me know.
<group ordered="false" collocated="true" id="grp_decoders">
...
<rsc_location id="locate_decoders" rsc="grp_decoders">
<rule id="rule_decoders_on_sysp" score="100">
<expression id="exp_decoders_on_sw" attribute="#uname"
operation="eq" value="sysp"/>
</rule>
</rsc_location>
Thanks,
