Latest Patents

Among his latest patents, one notable invention is the "Namespace salvage in logging-based filesystems." This innovation focuses on recovering a namespace held in a tree structure that has been corrupted. The process involves scanning a linear representation of pages belonging to the tree structure to extract keys from uncorrupted leaf pages into a new tree structure. The scanning is repeated over snapshots taken of the tree to identify missing keys. Upon discovering a missing key in an uncorrupted leaf page of a snapshot, it is copied into the new tree structure unless it has already been found in a more recent snapshot.

Another significant patent is the "File system namespace reconstruction." This invention describes systems and methods for reconstructing a namespace in response to data loss. The process includes locating metadata super segments within a set of file containers when the original namespace metadata is unreadable. Content handles linking the super segment to metadata for each file are reconstructed from the super segments. Additionally, inode numbers and M-tree identifiers are extracted for each file referenced by the super segments. The final step involves assembling a recovered namespace metadata tree data structure by aggregating and linking the U-trees.
