Updated data write method using a journaling filesystem

摘要

A problem with a journaling file system is that the load on input/output processing executed between a server and a storage system is increased because a journal log is written when the file system is updated and updated data is written when flush processing is executed. In a system according to the present invention, a storage system (2) that has received journal logs from a server (1) uses updated data included in the journal logs to execute flush processing.
