If the LV is active, reload its metadata.
In an environment where udev is used to manage the /dev content,
usage of this option is highly recommended. This is because refresh
also regenerates udev events for an LV based on which existing udev

Also, this operation may be useful if something has gone wrong,
or if some form of manual LV sharing is being used.
