</div>These are two functions that deal with resource allocation.<br>
They display the preference a resource has for a given node at<br>
different stages of the node allocation process.<br>

<br>
</div>At the point clone_color runs, none of the resources in that clone<br>
have been allocated yet.<br>
<br>
clone_color: ms-conntrackd allocation score on fw01: 10000<br>
clone_color: ms-conntrackd allocation score on fw02: 5000<br>
<br>
Lines 7-8 (above archival purposes) are the the scores for the clone<br>
container. They don't really matter but can be a useful sanity check<br>
as they'll be the simple sum of any location constraint scores.<br>
<br>
clone_color: updated-conntrackd:0 allocation score on fw01: 11001<br>
clone_color: updated-conntrackd:0 allocation score on fw02: 5000<br>
clone_color: updated-conntrackd:1 allocation score on fw01: 10000<br>
clone_color: updated-conntrackd:1 allocation score on fw02: 5101<br>
<br>
Lines 9-12 (above) are the scores for the primitive resources that the<br>
clone is made up of.<br>
These scores also include stickiness where appropriate and any scores<br>
inherited via colocation.<br>
<br>
native_color: updated-conntrackd:0 allocation score on fw01: 11001<br>
native_color: updated-conntrackd:0 allocation score on fw02: 5000<br>
<br>
Lines 13-14 (above) are the same as their equivalents (9-10) because<br>
no other members have been allocated yet.<br>
<br>
native_color: updated-conntrackd:1 allocation score on fw01: -INFINITY<br>
native_color: updated-conntrackd:1 allocation score on fw02: 5101<br>
<br>
The difference between native_color and clone_color are best<br>
demonstrated by lines 15-16 (above).<br>
By the time these lines are shown, the :0 instance of the clone has<br>
been allocated and this is reflected in the scores.<br>
Whereas line 11 showed a score of 10000 for fw01, we now show<br>
-INFINITY because another member of the clone ( :0 ) is active there -<br>
and since clone-node-max="1", we must choose another location for the<br>
:1 instance.<br>
<br>
updated-conntrackd:0 promotion score on fw01: 11000<br>
updated-conntrackd:1 promotion score on fw02: 5100<br>
<br>
And finally, since the clone is also a multi-state resource, we have<br>
the promotion scores which indicate that we'll promote<br>
updated-conntrackd:0 on fw01.<br>
<br>
<br>
<br>
Does that help?<br>
