See in attachment a report for the simple config below. Note that I 
dumbly erased the conf before doing the report but I paste it below.

I've done a very simple cluster. 2 nodes running a dummy resource with 2 
cloned pings testing a virtual IP that I activated or deactivated for 
the test.

11:20AM : cluster is up and running
11:25AM : shutdown the IP
11:30AM : force a refresh with attrd_updater (because pingd=1 still)
           It doesn't change anything still seen as up...
11:37AM : change a value in the CIB dampen from 120 to 121 for instance
           Now db2 pingd is null but db1 is still 1. crm changes have
           been done on db2 - dunno if it's linked.
11:40AM : start the IP again
12:00AM : IP is still seen as down...
