摘要: When a volume that was once associated with consistency group and is to be deleted from the storage system, designated as ghost within deletion of system delayed until there are no snapshots include pointer volume. The may counter counts number instances all volumes pointed or only to. reference this count determine whether immediately delete delay system.
