Embodiment Construction

[0022] The embodiments of the present application are applicable to log file management of distributed communication devices. figure 1 The structure of a distributed communication device is exemplarily shown. As shown in the figure, the distributed communication device includes a global control board 10 and n (n is an integer greater than 1) peripheral boards 11 . The storage system 12 is deployed on the global main control board 10 . The storage system 12 may be a high capacity magnetic disk. Each peripheral board 11 can transmit log data to the global control board 10 in the form of messages through the internal network of the device, and the global control board 10 stores the received log data in the storage system 12 in the form of log files.

[0023] The above are only typical scenarios used by the embodiments of the present application, and the embodiments of the present application may be applicable to any scenarios that require file storage and management.

Abstract

The invention discloses a file management method and device and relates to the technical field of data storage. In the invention, when a file needs to be created, the size of all files corresponding to a file information node in a file information linked list is obtained according to the file information linked list in a memory, and whether the quota requirement of a file storage space is satisfied or not is judged according to the size of all the files; if the quota requirement of the file storage space is satisfied, the file is created, and the file information node corresponding to the fileis inserted in the file information linked list; if the quota requirement of the file storage space is not satisfied, one or more files are deleted according to the file information linked list and according to the sequence from an early file storage time to a late file storage time, and the file is created and the file information node corresponding to the file is inserted in the file information linked list. By employing the file management method and device, the scanning operation of a storage medium can be reduced, thereby improving the file management efficiency.

Description

technical field [0001] The present invention relates to the technical field of data storage, and in particular, to a file management method and device. Background technique [0002] Many communication master devices are distributed systems consisting of multiple boards. In the entire system, there is a global control board, and other boards are called peripheral boards. Usually, due to cost and other requirements, the peripheral board will not deploy a large-capacity disk storage system, but only the global control board will deploy a large-capacity disk to save device-related information, including System log file. In large-scale communication devices, many types and quantities of log information are generated, such as some abnormal or meaningful information generated by the program itself, alarm information generated by the device itself, and signaling interaction information in the device. [0003] Since there is no disk on the peripheral board, when the log information...
