Hi
sorry I have to bother again about score calculation but I came across
something I don't understand and that might be a bug.
I have a master-slave drbd resource called ms-drbd (primitive is called
drbd2) and a group named testdb (4 primitives, "mount" being the first
primitive).
pingd multiplier is 300 (5 ping nodes)
default-resource-stickiness is 200
And these are my constraints:
<constraints>
<rsc_order id="drbd2_before_testdb" from="testdb"
action="start" to="ms-drbd2" to_action="promote"/>
<rsc_colocation id="testdb_on_drbd2" to="ms-drbd2"
to_role="master" from="testdb" score="300"/>
</constraints>
When I look at the scores, I see
drbd2:0 node1 0
Okay.
drbd2:0 node2 676
Weird
This looks like the crm_master value from the drbd OCF RA plus
stickiness times (number_of_group_items - 1).
How I come to think this has to do with the group? Because if I add
another item to the group, the score increases by 1 x stickiness.
Guess this shouldn't be, should it?
drbd2:1 node1 76
crm_master value from drbd OCF RA
drbd2:1 node2 -infinity
Okay.
mount node1 0
Okay.
mount node2 1100
300 (constraint)
+ 4 x 300 (pingd)
Regards
Dominik
