A method and system for storage space control

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...

Problems solved by technology

[0003] In the existing technology, a hard disk can only be mounted to one directory, and a directory can only be mounted to one hard disk. When the space capacity of a mounted space 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 file needs to be stored, it is difficult to expand the storage capacity due to the mounted space, and it cannot meet our diverse needs for storage space.
