Problems solved by technology

Because this solution is designed for desktop systems, and all hard disk partitions of the same capacity on the NAS system have the same structure, and the file system is not directly created on the hard disk partition, so the serial number of the file system cannot be obtained, so this solution does not work. Suitable for NAS systems as a method to identify hard drives

Embodiment Construction

[0037] Such as figure 1 As shown, it is a flow chart of the hard disk replacement control management method used in the network storage system of the present invention. First, record the tag data that can identify the hard disk in the hard disk (step 101); correspondingly record the data in the information file in the network storage system. Mark the data (step 102); simultaneously detect the actions of system startup and hard disk replacement (step 103); read the mark data of the hard disk and compare it with the corresponding data in the system file to determine the availability of the hard disk (step 104).

[0038] Wherein the hard disk mark data is recorded in the unused hidden sector of the hard disk, and the hidden sector refers to n unused sectors of the system whose sector number is smaller than the number of magnetic heads behind the master boot sector (MBR) of the hard disk. The number of magnetic heads of the current hard disk is greater than 16, so at least 15 sect...

Abstract

A hard disk replacement control and management method for a network storage system uses the recording of hard disk tag data as a basis for hard disk plug-in management to facilitate replacement of the hard disk. The method first records the tag data that can identify the hard disk in the hard disk, and Correspondingly record the mark data in the information file in the network storage system, and detect the actions of system startup and hard disk replacement at the same time. After detecting these actions, read the mark data of the hard disk and compare it with the corresponding data in the system file, so as to To determine the availability of the hard disk, the present invention uses the recording of the hard disk mark data as the basis for hard disk management, supports hot and cold swapping of the hard disk, and maintains the consistency of its access paths.

Description

technical field [0001] The invention relates to a hard disk control and management method in a data storage system, in particular to a hard disk replacement control and management method for a network storage system. Background technique [0002] At present, there are three main modes of disk storage on the market: CAS content addressable storage, NAS network attached storage or network attached storage, and SAN storage local area network. The latter two are the main choices in the network environment. [0003] After two rapid developments in computer computing power and network connectivity, people's demand for the network is no longer satisfied with connectivity, but more powerful information management capabilities. As more and more critical information is converted into digital form and stored in manageable media, new demands are placed on the network's ability to store and manage information. It can be said that whether the network has high efficiency depends on its da...
