Abstract
A method to manage storage of an object in a computer system having a first and a second storage management process (wherein the stored object has a data portion, a metadata portion and a fault tolerance data portion) includes receiving a memory access request from a client process, routing the memory access request to the first storage management process, determining the first storage management process has failed, routing the memory access request to the second storage management process (having access to the fault tolerance data portion), receiving a result from the second storage management process, and returning at least a portion of the result to the client process. The second storage management process may reconstruct at least a portion of the metadata portion, modify the fault tolerance data portion in accordance with the memory access request, and store the modified fault tolerance information.
