+#
+# Configures Cinder to use GlusterFS as a volume driver
+#
+# === Parameters
+#
+# [*glusterfs_shares*]
+#   (required) An array of GlusterFS volume locations.
+#   Must be an array even if there is only one volume.
+#
+# [*volume_backend_name*]
+#   (optional) Allows for the volume_backend_name to be separate of $name.
+#   Defaults to: $name
+#
+# [*glusterfs_disk_util*]
+#   Removed in Icehouse.
+#
+# [*glusterfs_sparsed_volumes*]
+#   (optional) Whether or not to use sparse (thin) volumes.
+#   Defaults to undef which uses the driver's default of "true".
+#
+# [*glusterfs_mount_point_base*]
+#   (optional) Where to mount the Gluster volumes.
+#   Defaults to undef which uses the driver's default of "$state_path/mnt".
+#
+# [*glusterfs_shares_config*]
+#   (optional) The config file to store the given $glusterfs_shares.
+#   Defaults to '/etc/cinder/shares.conf'
+#
+# === Examples
+#
+# cinder::backend::glusterfs { 'myGluster':
+#   glusterfs_shares = ['192.168.1.1:/volumes'],
+# }
