 * createonly (Parameter) Default value: false - If set to true the volume group will be created if it does not exist. If the volume group does exist no action will be taken. Defaults to `false`.  Allowed Values:
    - `true`
    - `false`
+* followsymlinks (Parameter) - If set to true all current and wanted values of the physical_volumes property will be followed to their real files on disk if they are in fact symlinks. This is useful to have Puppet determine what the actual PV device is if the property value is a symlink, like '/dev/disk/by-path/xxxx -> ../../sda'. Defaults to `false`.
 * physical_volumes (Property) - The list of physical volumes to be included in the volume group; this will automatically set these as dependencies, but they must be defined elsewhere using the physical_volume resource type.
