Good morning Andrew
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).
that would make sense.
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?
it should.
the group needs to go with the master... so it makes sense that you
should take the groups location preferences into account when
deciding where to place and promote drbd
Full ack on that, but I didn't configure it (at least not that I
knew of - yet). So it's known and wanted to work this way. Sweet!
Just curious: I suppose its my first constraint that does this job?
second - the colocation one
Regards
Dominik
