Abstract:
A system to delete a data volume may include storage of a plurality of data pages of the data volume of a data area into a cache, prevention of writing of data pages to the data volume, and designation of each of the plurality of data pages in the cache as modified. The system may also include writing of all data pages in the cache that are designated as modified to a respective location in one or more other data volumes of the data area, and updating, for each of the written data pages, a converter page of the cache to associate the written data page with its respective location in the one or more other data volumes.
