  • Method for quickly identifying data residing on a volume in a multivolume file system
    Patent number: 9110919
    Abstract: A method for quickly identifying data residing on a volume in a multivolume file system. The method includes generating a file location map, the file location map containing a list of the locations of files that occupy space on each of a plurality of volumes of the file system. The file system comprises least a first volume and a second volume. The file location map is updated in accordance with changes in a file change log for the file system. Data residing on the first volume of the file system is identified by scanning the file location map.
    Type: Grant

  • Using a per file activity ratio to optimally relocate data between volumes
    Patent number: 8732217
    Abstract: A method for identifying data for relocation in a multivolume file system. The method includes generating a file location map, the file location map containing a list of the locations of files that occupy space on each of a plurality of volumes of the file system, wherein The file system comprising least a first volume and a second volume. The method further includes updating the file location map in accordance with changes in a file change log for the file system, and identifying data residing on the first volume of the file system by scanning the file location map. Using the identified data, a ratio of per-file activity during a first time period relative to overall file system activity over a second time period is calculated to derive a file activity ratio for each of the files of the identified data. Files are then selected for relocation based on the file activity ratio.
