+# == Define: tripleo::pacemaker::resource_restart_flag

+# Creates a flag file on the filesystem to signify that a pacemaker
+# resource needs restarting (usually to pick up config changes after
+# they've been written on all nodes).
+#
+# === Parameters
+#
+# [*title*]
+#   The resource name in Pacemaker to restart. If it's a cloned
+#   resource, the name should include the '-clone' part.
