Abstract:
1. A method for performing a data-modifying operation in a file system that includes a plurality of servers that store replicas of data, one of the servers serving as a primary replica server for one of the replicas of data and at least one other one of the servers serving as at least one secondary replica server for the one replica of data, the method comprising: sending data associated with the data-modifying operation to the primary replica server and the at least one secondary replica server; and sending a data-modifying control signal that requests execution of the data-modifying operation on the data associated with the data-modifying operation to the primary replica server and the at least one secondary replica server, where a sequence in which the data associated with the data-modifying operation is received at each of the primary replica server and the at least one secondary replica server is independent of a sequence in which the data-modifying control signal is received at each of the primary replica server and the at least one secondary replica server.
