Abstract

The invention provides a management method and device of a network storage system. The method comprises the following steps: obtaining the first state information of a first storage system and the second state information of a second storage system; utilizing the first state information and the second state information to determine the fault situation of the network storage system; and when the fault situation is that the network storage system has faults, utilizing the fault situation to determine that the storage system which provides data request service is the first storage system or the second storage system. Through the technical scheme of the invention, the data request service of a master storage system or a slave storage system does not need to be manually suspended, service interruption is avoided, manual operations are reduced, and wrong manual behaviors brought by the manual operations are avoided. A fissure problem in a remote mirror image can be solved, an automatic fault recovery function is provided, and dual protection of no service interruption and no data loss is provided.

Description

technical field

[0001] The invention relates to the technical field of storage, in particular to a management method and device for a network storage system. Background technique

[0002] As the three basic fields of information technology, computing, transmission, and storage are constantly evolving in the tide of information. With the rapid expansion of user data, computing and storage are gradually separated, and storage forms an independent network storage system. The independent network storage system can provide larger storage space, expand capacity according to user needs, and provide more professional protection measures for user data, such as RAID (Redundant Arrays of Independent Disks, Redundant Array of Independent Disks) , snapshot, clone, remote copy, remote mirror, etc. Among them, remote mirroring is one of the basic features provided by the network storage system. The main working principle is to make two identical copies of user data and store them in two i...
