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 large-capacity magnetic disk. Each peripheral board 11 can transmit the log data to the global control board 10 in the form of a message 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 a log file.

[0023] The above are only typical scenarios used in the embodiment of the present application, and the embodiment of the present application can be applied to any scenario requiring file storage and management.

Abstract

The present application discloses a file management method and device, which relate to the technical field of data storage. In the present application, when a file needs to be created, the sizes of all files corresponding to the file information nodes in the file information linked list are obtained according to the file information linked list in the memory, and whether the quota requirements of the file storage space are met according to the sizes of all files; If satisfied, create a file, and insert the file information node corresponding to the file in the file information linked list; if not, delete one or more files according to the file information linked list and in the order of file storage time from early to late A file is created, and a file information node corresponding to the file is inserted into the file information linked list. By adopting the present application, the scanning operation of the storage medium can be reduced, thereby improving the file management efficiency.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a file management method and device. Background technique [0002] Many communication master devices are a distributed system composed of multiple boards. In the whole system, there is a global control board, and other boards are called peripheral boards. Usually, due to the needs of cost and other aspects, 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 the relevant information of the device, which includes System log files. In large-scale communication equipment, many types and quantities of log information will be 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 lo...
