[Pacemaker] understanding scores

Hi,

I am trying to understand how the scores are calculated based on the
output of ptest -sL and I have few questions
Below is my scores with a  line number column and the bottom you will
find my configuration

So, let's start

1 group_color: pbx_service_01 allocation score on node-01: 200
 2 group_color: pbx_service_01 allocation score on node-03: 10
 3 group_color: ip_01 allocation score on node-01: 1200
 4 group_color: ip_01 allocation score on node-03: 10
so for so good, ip_01 has 1000 due to resource-stickiness="1000" plus
200 from the group location constraint

 5 group_color: fs_01 allocation score on node-01: 1000
 6 group_color: fs_01 allocation score on node-03: 0
 7 group_color: pbx_01 allocation score on node-01: 1000
 8 group_color: pbx_01 allocation score on node-03: 0
 9 group_color: sshd_01 allocation score on node-01: 1000
 10 group_color: sshd_01 allocation score on node-03: 0
 11 group_color: mailAlert-01 allocation score on node-01: 1000
 12 group_color: mailAlert-01 allocation score on node-03: 0
hold on now, why all the above resources have 1000 on node-01 and not
1200 as fs_01

 13 native_color: ip_01 allocation score on node-01: 5200
5 resources x 1000 from resource-stickiness="1000" plus, right? what
is the difference between in native and group?

 14 native_color: ip_01 allocation score on node-03: 10
 15 clone_color: ms-drbd_01 allocation score on node-01: 4100
why 4100?

 16 clone_color: ms-drbd_01 allocation score on node-03: -1000000
I guess this comes out from the colocation constraint

 17 clone_color: drbd_01:0 allocation score on node-01: 11100
i am lost now so I will stop here :-)

 18 clone_color: drbd_01:0 allocation score on node-03: 0
