Abstract
One aspect of the present invention provides an operation for recovering lost space and maintaining data consistency in a storage environment by providing a two-way orphan reconciliation method for extremely large file systems, such as a Hierarchical Storage Management (HSM) system which manages billions of files. This highly scalable and parallelizable orphan identification process may be used in a HSM controlled environment to enable the execution of a two-way file orphan check. In one embodiment, this orphan check identifies file system client orphans and server object orphans in a single pass by comparing a queue containing a list of migrated files on a storage repository server with a queue containing a list of stub files on a file system. If the queue elements do not match, a file system orphan or server object orphan can appropriately be identified.
