Fencing history is totally independent from failure history for
resources that is
recorded in the cib. That is part of the strategy to have the fencing framework
operate kind of independently from DC, scheduler and stuff.
It lives purely within the framework built by the fenced instances and
broadcasted
between those instances to keep it current - or purged if requested.
DC role thus isn't relevant for working with the fencing history.
Of course operations on the fencing history can create logs but they may be
below the usually enabled level. Nothing there should influence the behavior
of the cluster (you can't purge pending actions).
