Abstract
File names and inodes are indexed directly in a filesystem namespace consisting of a layered set of key value store (KVS) database logical tables. The KVS is used directly for organizing file and directory metadata on a cluster file system instead of traditional Btree structures. Embodiments provide file deletion in the file system namespace, and other features include snapshot deletion and cleaning the namespace. A name hash index is used to speed filename lookup in the file system namespace. Two key types of INODE and DIRENT are used to encode namespace metadata using self-identify variable length records in the namespace. Point-in-time snapshot copies are also formalized using KVS database operations as well operations on sets of snapshots for operations including garbage collection and data replication.
