Embodiment 1

[0034] The present invention proposes a storage space control method and system, such as figure 1 As shown, a storage space control method is given.

[0035] In step S101, when the hard disk file system is formatted, a mounted hard disk space management area is set on the hard disk for storing the information of the hard disk, the list of mounted hard disks and the list of file inodes.

[0036]Taking the ext3 file system as an example, when formatting the hard disk with the ext3 file system, the hard disk will be divided into an index area and a data area. The index area contains several inodes, and each inode corresponds to a file, including file-related description information, file data storage address, etc., such as figure 2 As shown, the inode information table in a storage space control method proposed based on Embodiment 1 of the present invention is given.

[0037] When the hard disk is formatted with the file system, the mounted hard disk space management area is s...

Abstract

The invention provides a method and a system for storage space control, and the method comprises the steps: achieving the batch mounting through the mount, and mounting a to-be-mounted hard disk whenthe to-be-mounted hard disk is not recorded in a mounting hard disk list of a mounting hard disk space management region; when the to-be-mounted hard disk is recorded in the mounting hard disk list ofthe mounting hard disk space management area and the universal unique identification code of the to-be-mounted hard disk is recorded in the mounting hard disk space management area, mounting the to-be-mounted hard disk; wherein the mounted hard disk space management area is pre-configured on the hard disk and is used for storing a mounted hard disk list and a UUID. The umount is mounted to all hard disks under the catalogue to be fully unloaded; and a mountshow displays all the hard disk information mounted under the catalogue by the count. The method further comprises writing or reading thefile into or from the directory after the hard disk is mounted. Based on the method, the invention provides a storage space control system. According to the method, a plurality of hard disks are mounted to a certain same directory in batches, so that a larger storage space is formed by the plurality of hard disks.

Description

technical field [0001] The invention belongs to the technical field of hardware storage, and in particular relates to a storage space control method and system. Background technique [0002] In the LINUX operating system, the mount command is generally used to mount the local hard disk, storage-mapped hard disk, NFS mapping space, etc. to the local directory of the operating system for reading, writing and storing data. This is a flexible, simple and convenient way to obtain How to store directories. Similar to the following command mount / dev / sdb1 / data, the / dev / sdb1 local hard disk is mounted to the / data directory, and then unmounted by umount / data after use. [0003] In the prior art, one hard disk can only be mounted to one directory, and one directory can only be mounted to one hard disk. When a mounted space capacity is used up, it is generally difficult to expand the space capacity. When there is a demand for more capacity in a storage space and a single super-large...
