Once a resource fails on a node, its failcount increases and
under normal circumstances the cluster won't try to start that
resource on that node again. The administrator has to clean the
failcount first.

This is because the failcount is in the status section of the
CIB. The status is not saved between restarts. So, the failcount
is essentially reset.
