RAID-Targeted Operating System Installation via Unique Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing an operating system on RAIDs are cumbersome and inconvenient due to the need for users to manually track RAID creation sequences, leading to potential installation on unintended disks.
Innovation Solution
A method and device that determine a target RAID and partition for operating system installation by using unique identifiers and mount point correspondences, allowing user specification and automated installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually track RAID creation sequences to install operating systems, then installation can be performed on specific disks, but the process becomes cumbersome and error-prone
Solution Approach 1:
The system automatically generates and assigns unique identifiers to RAIDs and maintains correspondence relationships between identifiers and mount points without requiring user intervention. The installation process automatically queries these relationships to determine target installation disks, eliminating the need for users to manually track RAID creation sequences while ensuring accurate disk identification.
2Productivity
If automatic installation methods are used without unique identifiers, then installation speed increases, but installation may occur on unintended disks
Solution Approach 1:
The system establishes a feedback mechanism where unique identifiers are assigned to RAIDs and correspondence relationships are maintained between identifiers and mount points. During installation, the system queries this correspondence relationship to automatically determine the correct target disk, providing feedback that ensures both automated operation and accurate disk selection, thus achieving high efficiency without sacrificing reliability.
3Adaptability or versatility
If RAID creation sequence is used to identify target disks, then disk selection is possible, but the method becomes complex and inconvenient
Solution Approach 1:
The system changes the identification parameter from RAID creation sequence (which requires tracking and is complex) to unique identifiers (which are simple and direct). Each RAID is assigned a unique identifier, and the correspondence relationship between identifiers and mount points is maintained automatically. This parameter change simplifies the installation process while preserving the ability to select specific disks for operating system installation.

AI summary
A method and device for installing an operating system are provided. In an example, in a temporary system, a target RAID for installing the operating system and a unique identifier of the target RAID are determined in response to a user operation of specifying a disk array RAID. Then, a mount point corresponding to the RAID unique identifier is found according to a correspondence between a unique identifier of a RAID and a mount point, and the target partition for installing the operating system is determined in the found mount point, and an identifier is added to the target partition. In a small system for an operating system to be installed, an installation partition and an installation disk where the installation partition is located may be determined by the identifier of the target partition, and the operating system is installed into the installation partition of the installation disk.
