No. I tried various numbers, got this: If I set the score to 1000, the DBIP score on srvplan1 is 9250. If I set the score to 10000, the DBIP score on srvplan1 is 250. If I set the score to 15000, the DBIP score on srvplan1 is... guess what? 10250. The same for 100000. The threshold seems to be 10150: with this value, the score is 100, with 10251 it reverts to 10250. The score for srvplan2 remains at -INF in all cases, though. _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
