| Zusammenfassung: | The embodiment of the invention provides a log operation method, a log operation device and a file system. The file system comprises a log system and at least two catalog subtrees, wherein the log system comprises a log tree root and at least two log subtrees connected with the log tree root; the at least two log subtrees correspond to the at least two catalog subtrees; the log tree root is used for storing the logs of the at least two catalog subtrees and the addressing information of the at least two log subtrees; and the at least two log subtrees are used for storing the logs of catalogs and files in the corresponding catalog subtrees. In the embodiment of the invention, through the technical means that the log system of the file system is divided into the log tree root and the at least two log subtrees, and the at least two log subtrees correspond to the at least two catalog subtrees in the file system, the distributivity of the logs and the independence of log operation are improved, and the log operatio |
