Document system and document storage managing method thereof

Abstract

The invention discloses a document storage managing method of a document system. The method comprises the following steps: communicating with a client-side, receiving documents sent by the client-side, obtaining the data size of the documents received from the client-side, comparing the data size with a preset reference value, distributing storage space for the documents in a dynamic mode according to the data size, providing distributable storage space, and storing the documents in the storage space. The invention further discloses the document system. According to the document system and the document storage managing method thereof, the utilization efficiency and the service life of a disk used as a carrier storing the documents in the document system are both considered, the waste of storage space in the document system is reduced, disk fragmentation in the document system is reduced, the moving times of a magnetic reading head at document reading time is reduced, and the usability of the disk used as the carrier storing the documents in the document system is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of file storage, in particular to a file system and a method for storing and managing files. 【Background technique】 [0002] Currently, the mainstream file systems include GFS (Google File System, Google File System) and HDFS (Hadoop Distributed File System, distributed file system). [0003] The technical solutions for storage and management of files by these two file systems are as follows: the files are divided into multiple blocks (Chunks) according to the amount of data in the files, and then the files are stored in the form of blocks. [0004] In the above two file systems, the size of the blocks divided by GFS for files is fixed, that is, regardless of the amount of data in the files, they are all divided into blocks of fixed size, and then stored. However, if the data volume of the file is less than the size of the block, the above-mentioned technical solution will waste a lot of storage space; an...

[0004] In the above two file systems, the size of the blocks divided by GFS for files is fixed, that is, regardless of the amount of data in the files, they are all divided into blocks of fixed size, and then stored. However, if the data volume of the file is less than the size of the block, the above-mentioned technical solution will waste a lot of storage space; and the blocks divided by HDFS are self-defined, that is, the data volume of the file and the size of the block are first compared. In comparison, if the data volume of the file is greater than the size of the block, the file is divided into several blocks, and the last block is divided according to the actual size of the remaining file; if the data volume of the file is smaller than the size of the block, then According to the actual data volume of the file, it is divided into blocks to store, but this technical solution will generate a lot of disk fragments, that is, the file will be stored on many disk fragments, and the number of head movements will increase significantly when reading the file , making the reading speed of the file slower, and the disk is also prone to failure, reducing the availability of the disk
