Hi,

The most common factors in scores are constraints and stickiness. If
you run "cibadmin --query --scope=constraints" (or the equivalent in a
higher-level tool), you can see what constraints are in effect.

Other things that can affect scores include previous failures of the
resource on a node, and whether you have configured advanced features
such as the symmetric-cluster property, utilization attributes, or node
health monitoring.
