Embodiment Construction

[0099] In order to provide an effective implementation solution, the present invention provides the following embodiments, which will be described below in conjunction with the accompanying drawings.

[0100] The present invention firstly provides a disk storage space management method, including such as figure 1 Steps shown:

[0101] Step 101: Identify the operation of inserting the disk into the storage device;

[0102] Step 102: According to the metadata and file system carried by the disk itself, identify whether the newly inserted disk carries data;

[0103] Step 103: When the newly inserted disk carries data, according to the user's instruction, retain the data in the newly inserted disk, and mount the file system in the newly inserted disk as a shared directory on the storage device.

[0104] It can be seen from the above that the disk storage space management method provided by the present invention can present the file system in the disk to the user in the form of a...

Abstract

The invention discloses a disk storage space managing method, apparatus and storage device. The method comprises the following steps of identifying an operation that a disk is inserted into the storage device, identifying whether a newly-inserted disk carries data according to metadata and file systems carried by the disk, and preserving data of the newly-inserted disk according to a user instruction and mounting the file systems of the newly-inserted disk into a shared catalogue in the storage device or mounting file systems of a disk array RAID of the newly-inserted disk into a shared catalogue in the storage device when the newly-inserted data carries data. The apparatus comprises a data identifying module, a data reserving module and a catalogue mounting module. By the use of the method, the device and the storage device, changes of the disk of the storage device can be sensed, so the user can preserve original data of the disk.

Description

technical field [0001] The invention relates to storage technology, in particular to a disk storage space management method, device and storage device. Background technique [0002] Today, mankind has already entered the information age. Various electronic devices, such as smart phones, PCs, digital cameras, etc., are closely related to people's lives. With the emergence of Blu-ray video, lossless music, high-resolution photos, etc., the amount of household data has increased on a large scale. As a result, there is an increasing demand for home-specific storage devices. [0003] Soft RAID (Redundant Arrays of Independent Disks, disk array) refers to a disk array generated by software. By using multiple block devices (such as disks, disk partitions, logical volumes, etc.) as members, a new block device with data protection function is generated through striping and other technologies. Specifically, it refers to the block device generated by using the mdadm command with th...
