ABSTRACT:
Described is a method and system by which reports of storage usage in computer systems are generated in an efficient manner by consolidating multiple requests for reports into a minimal number of volume scans, including by intelligently selecting a scanning method (e.g., of file system metadata versus find-first/find-next) and by performing parallel scans on different volumes. Namespace consolidation scans namespaces together, so as to generate multiple reports from the same set of files, reducing the number of volumes scans required to collect the data. Each volume scan may be a find-first, find next directory-based scan, or a volume metadata database scan. Time consolidation groups independent storage report generations together, such as storage report requests received within an administrator-specified interval. Parallel scans of different volumes may be performed, subject to I/O and processing resource limitations, and so that volumes partitioned on the same spindle are not scanned in parallel.
