+# == Class: tripleo::fencing
+#
+# Configure Pacemaker fencing devices for TripleO.
+#
+# === Parameters:
+#
+# [*config*]
+#  JSON config of fencing devices, using the following structure:
+#    {
+#      "devices": [
+#        {
+#          "agent": "AGENT_NAME",
+#          "host_mac": "HOST_MAC_ADDRESS",
+#          "params": {"PARAM_NAME": "PARAM_VALUE"}
+#        }
+#      ]
+#    }
+#  For instance:
+#    {
+#      "devices": [
+#        {
+#          "agent": "fence_xvm",
+#          "host_mac": "52:54:00:aa:bb:cc",
+#          "params": {
+#            "multicast_address": "225.0.0.12",

+#          }
+#        }
+#      ]
+#    }
+#  Defaults to {}
+#
+# [*tries*]
+#  Number of attempts when creating fence devices and constraints.
+#  Defaults to 10
+#
+# [*try_sleep*]
+#  Delay (in seconds) between attempts when creating fence devices
+#  and constraints.
+#  Defaults to 3
