Abstract
A technique of updating leaf pointers in a storage system includes creating a point-in-time copy of persisted metadata pages and scanning the copy for leaf pointers that point to redirected virtual blocks. Metadata pages that contain leaf pointers that point to redirected virtual blocks are read from cache and processed for updates, but no action is taken in cache for metadata pages that do not contain such leaf pointers.
