Abstract
Described are systems and techniques for losslessly restarting subsystems in a distributed file system. By partitioning functionality and logging appropriately across the kernel and user-level boundaries on a client, the user-level subsystem may be made losslessly restartable. In particular, a map assisted state transfer may include receiving one or more state updates, marshaling one or more active data-structures into a marshaled shadow, applying the received state updates to the marshaled shadow and re-instantiating the active data-structures by unmarshaling the marshaled shadow.
