Problems solved by technology

Problems usually occur in such operations, because when the disk device 11 is moved from the source disk system 101 to the target disk system 102, the file information in the corresponding database 12 does not move, thus causing the interface of the file information to be abnormal. use, so that the corresponding application cannot run normally
In the database 12 on the source disk system 101, the file information on the disk device 11 that has been moved is also stored. When the interface for using the file information is executed, the corresponding file cannot be found, and an error will be generated, while the database of the target disk system 102 There is no file information on the moved disk device 11 in 12, and an error will also occur

Embodiment Construction

[0045] For the system and method for storing file information using a distributed database according to the present invention, please refer to FIG. 3 , which is an architecture diagram of the system for storing file information using a distributed database according to the present invention. As shown in Figure 3, the present invention all establishes database in each disk device 11 of disk system 10, claims these databases here as distributed database 13, and this distributed database 13 is in order to store the file information on this disk device 11, Called by the application. Like this, as shown in Figure 4, when the disk device 11 moved to the target disk system 102 by the source disk system 101, even if the disk device 11 was moved, the file information in the corresponding distributed database 13 would also be consistent with the disk device 11 If they are moved together, it can be guaranteed that the application programs that use the file information can use the informa...

Abstract

The present invention relates to a system and method for storing file information by usind distributed data base. In its magnetic disk system every magnetic disk equipment includes a distributed data base, in said distributed data base is stored a file information correspondent to the file in said magnetic disk equipment, and can be called by application program, so that, if said magnetic disk equipment is moved, said file information also can be called.

Description

technical field [0001] The invention relates to a file information storage system and a storage method thereof, in particular to a system and a storage method for storing file information using a distributed database. Background technique [0002] Please refer to FIG. 1 , which is a schematic structural diagram of application database record file information in the prior art. As shown in FIG. 1 , when the application program calls the file system in the disk device 11 , it usually needs to use the file information stored in the database 12 . When the file information changes, the corresponding item in the database 12 needs to be modified. Many hardware environments used today support hot plugging of disk devices 11. As shown in FIG. 102) on. Problems usually occur in such operations, because when the disk device 11 is moved from the source disk system 101 to the target disk system 102, the file information in the corresponding database 12 does not move, thus causing the i...
