I have this config (part of it):
With this values I have only one failure (with mathematical function) :
150 -100 +50 / abs(-100) = 1, only one failure (I think...) . The
resource moves all the time to node portatil1 when it is recovered.
After a portatil1 failure IP_ADDR goes to portatil2 and then when
portatil1 is recovered it goes again to portatil1, why ??
