dummy01 got the fail-count,
so dummy01 should move from bl460g1n13 to bl460g1n14.
Why does it re-start on the failure node?

I got the latest changeset from hg;

Pacemaker 1.0.10 moved the failure resource to the other node.
It's the expected behavior.

I attached the hb_report which includes the above pe-input-7.bz2.

Thanks,
