[Linux-HA] about the resource stickiness

[TORRESANI, Roberto]

Well...I tried ptest and, really, after some -V it puts out some very interesting information. ;-)
The only thing that remains obscure to me is how the colocation constraints are involved in the
node's score calculation.
Having:
- heartbeat 2.0.7
- a 1st resgroup (mysql) made of 2 res
- a 2nd resgroup (apache) made of 4 res
- a colocation constraint between them
- resource_stickiness=50
- resource_failure_stickiness=-100
the total score shown by ptest is 1900 (I suppose it would be 1900/2=950 with the patch), so:
 
mysql: 50 x 2 = 100
apache: 50 x 4 = 200
mysql + apache = 300
...and the rest of the score?
How is it calculated?
 
I'm sorry, I can't include the CIB in this moment (I'm at home), but I attach the interesting part of ptest output.
 
Regards,
Roberto
