ABSTRACT:
A method and apparatus for assisting in file recovery after a network fault uses a block state indicator in a client cache. After file data is stored in the client cache, the block state indicator is set to a client-cached state. After the file data is stored in a server cache, the block state indicator is set to a server-cached state. After the file data is stored in a non-volatile store attached to the server, the block state indicator is set to a stored state. If the data in server cache is lost or compromised due to a network fault, the data maintained in client memory is retransmitted. In a similar manner, file locks and file semaphores are re-established after a network fault.
