Example Embodiment

[0108] In order to make the objectives, technical solutions, and advantages of the present invention clearer and more comprehensible, a metadata management method for splitting a namespace of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0109]The metadata management method for splitting the name space of the present invention, as shown in Figure 1, is to split the directory into multiple copies by splitting the name space and distribute them to all metadata servers (MetadataServer, MDS for short) Above, each MDS has a sub-directory (sub_dir). The contents of the directory entries stored in different sub_dirs are different, and the offset of the stored directory entries increases according to the sequence number of the sub_dir from small to larg...

Abstract

The invention discloses a metadata managing method for splitting name space, which comprises the following steps: establishing document system; managing the established document system. Wherein, management of established document system also comprises that client establishes catalogues; client establishes documents; client executes query operation; client executes readable catalogues operation; client deletes documents; client deletes catalogues; client executes relief operation; client executes rename operation; client establishes hard links; client establishes soft links. The invention can avoid the access focus of the same catalogue while improving extensibility of metabase server.

Description

technical field [0001] The invention relates to the field of storage system architecture, in particular to a metadata management method for splitting namespaces. Background technique [0002] With the continuous advancement of the world's informatization, computers have become an indispensable tool in various industries. The storage management software that carries the information in the computer is being paid more and more attention by people with the sudden increase of the amount of information. [0003] The function of storage management software is to organize physical storage media (such as disks, disk arrays) into logical groups to achieve various functions and features. The operating system provides storage services for upper-layer users by calling the interface of the storage management software. [0004] There are two types of data processed in the storage system, one is data used by users, and the other is metadata used by the storage system to manage user data. ...
