Abstract

The invention is aimed at providing a method and a device for managing meta information. The method comprises the following step: in each data block of a target system, storing or updating meta information corresponding to the data block. Compared with the prior art, the method and the device have the following advantages: by storing the meta information into the data blocks, the loss of mass data due to file corruption can be avoided, and the security of data storage is improved; besides, a plurality of threads can be created according to the solution to load the meta information in a parallel manner, so that the system start speed is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for managing meta information. Background technique [0002] Data storage systems based on the prior art generally store metadata persistently in media such as disks. This method has the following defects: 1) It takes a long time to load and restore the meta information when the system starts. The reading of meta-information files and the deserialization of information into the specified memory data structure will consume quite a long time, thus affecting the startup speed of the system; Disk bad blocks and other problems are damaged, and once the file is damaged, it will cause a large amount of data loss on the entire node. Contents of the invention [0003] An object of the present invention is to provide a method and apparatus for managing meta information. [0004] According to one aspect of the present invention, a method for managing meta ...
