 If set, the volume group will be activated exclusively.  This option works one of
 two ways.  If the volume group has the cluster attribute set, then the volume group
 will be activated exclusively using clvmd across the cluster.  If the cluster attribute
 is not set, the volume group will be activated exclusively using a tag and the volume_list 
 filter. When the tag option is in use, the volume_list in lvm.con must be initialized. This 
 can be as simple as setting 'volume_list = []' depending on your setup.
