Problems solved by technology

A disk, after being pulled out and then plugged back in, although it is still the same disk at this time, the disk serial number has not changed, but the original partitions in the disk may have been deleted, modified or re-partitioned, and regardless of the home dedicated storage device When the system is recognized, whether the minor device number of the disk partition is the same as the original one, the above situations cannot be handled by the MD driver
For a brand new disk, or a disk whose data does not need to be kept, you can directly clear the data on the disk and manage it according to our method; but for the user's old disk, once the disk (or its partition) becomes a RAID members, then all the data on the disk will be lost

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

A management method and apparatus for a disk storage space, and a storage device. The method comprises the steps of: recognizing an operation of inserting a disk into a storage device; recognizing whether the newly inserted disk carries data; and when the newly inserted disk carries data, according to a user instruction, reserving data in the newly inserted disk, and mounting, onto the storage device, a file system in the newly inserted disk to be a shared directory, or mounting, onto the storage device, a file system in a disk array RAID of the newly inserted disk to be a shared directory.

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...
