Abstract :
Harp is a replicated Unix file system accessible via the VFS interface. It provides highly available and reliable storage for files and guarantees that file operations are executed atomically in spite of concurrency and failures. Replication enables Harp to safely trade disk accesses for network communication and thus to provide good performance both during normal operation and during recovery. The authors focus on the techniques Harp uses to achieve efficient recovery
