US Patent 10261944 Managing file deletions in storage systems

A method is used in managing file deletions in storage systems. A request to delete a set of replicas of a file of a file system is received. A replica of the file represents a state of the file at a particular prior point in time. A sibling indirect block associated with a portion of the file identified for deletion is identified. The sibling indirect block includes a set of file system blocks. A set of indirect blocks associated with replicas of the file is identified. The sibling indirect block and the set of indirect blocks share a subset of the set of file system blocks where the set of indirect blocks have been identified for deletion. Weight information associated with the subset of the set of file system blocks shared among the set of indirect blocks that have been pending deletion is merged. The set of indirect blocks are processed for deletion concurrently. Metadata of the sibling indirect block is updated with the merged weight information.
