Abstract
An exemplary embodiment of the present invention provides a method of processing a file system transaction in a distributed file system. The method includes receiving a transaction request from a computer, wherein the transaction request includes file data to be stored and a first segment identifier that determines a destination of the file data. The method also includes generating a first distributed journal record corresponding to the file data. The method also includes generating a first file operation request based, at least in part, on the transaction request. The method also includes sending the first file operation request to a first segment server corresponding to the first segment identifier, wherein the first segment server generates a second distributed journal record corresponding to the file data on a memory device associated with the first segment server.
