发明名称 System and method for storage management
摘要 A method, computer program product, and computing system for defining a transactional log file for a data storage system including a data array. A first plurality of IO requests for the data storage system is processed. The transactional log file is updated to include information concerning the first plurality of IO requests. An IO pointer is defined to locate a specific IO request of the first plurality of IO requests within the transactional log file. File system metadata is defined on the data array for the data storage system.

主权项 1. A computer-implemented method comprising: defining a transactional log file for a data storage system including a data array, wherein the transactional log file is configured to be a continuous non-segmented sequentially written transactional log file; processing a first plurality of IO requests for the data storage system; updating the transactional log file to include information concerning the first plurality of IO requests; defining an IO pointer to locate a specific IO request of the first plurality of IO requests within the transactional log file; defining a unique transaction identifier, wherein the unique transaction identifier is incremented when a new piece of information is written to the transactional log file; defining file system metadata on the data array for the data storage system; sensing the occurrence of a transmission failure portion within the transactional log file; and repairing file system metadata based, at least in part, upon a Last Good Transaction (LGT) indicator included within the transactional log file pointing to the transmission failure portion.
