Pacemaker saves the cluster state at each calculated transition. This
can come in handy when investigating after a problem occurs, to see what
changed and how the cluster responded.

The files are not necessary for cluster operation, so you can clean them
as desired. The cluster can clean them for you based on cluster options;
see pe-error-series-max, pe-warn-series-max, and pe-input-series-max:
