Abstract
A self-healing computer storage system utilizes a proxy storage management process to service memory access requests directed to stored objects whose designated storage management process has failed. The proxy accesses the relevant parts of the stored objects fault tolerance information to service memory access requests, updating the stored object's fault tolerance information to reflect any changes. When the previously failed storage management process is restarted, it determines if the fault tolerance information for any of the objects (or parts thereof) it manages have been modified (i.e., by a proxy). If such indication is found, the restarting storage management process reconstructs its stored object data (and metadata) from the stored objects' fault tolerance information.
