Method for realizing capacity expansion of root partitions of Kylin systems

Abstract

The invention discloses a method for realizing capacity expansion of root partitions of Kylin systems, and relates to the field of system partition management. The method comprises the following steps of: mounting an external disk which has a capacity greater than a partition, which can be normally started, of a Kylin system under the system on the basis of the Kylin system, backing an MBR master boot record up to the external disk, and downloading the external disk; creating a new disk partition, a logical volume and a new file system, and creating a backup / catalog and a boot catalog to the new file system; and modifying a starting file, recovering the MRB master boot record to the logic volume and modifying a grub boot, and starting and booting the system to the new disk partition. By utilizing the method, by utilizing a logical volume management function of Linux, the external disk is utilized to start the system to carry out partition size adjustment without halt, so that the root partitions of the system are fundamentally adjusted and benefit is brought to manage stored files by the system.

Description

technical field [0001] The invention discloses a method for realizing expansion of a root partition of a system, and relates to the field of system partition management, in particular to a method for realizing expansion of a root partition of a winning Kylin system. Background technique [0002] The difficult decision that is often encountered when using the Linux operating system is how to correctly evaluate the size of each partition to allocate appropriate hard disk space. Ordinary disk partition management methods cannot change the size of logical partitions after they are divided. When a logical partition cannot store a certain file, this file cannot be stored across multiple partitions due to the limitation of the upper file system, so it cannot At the same time put it on another disk. When a certain partition runs out of space, the solution is usually to use a symbolic link, or use a tool to resize the partition, but this is only a temporary solution and cannot funda...

Ordinary disk partition management methods cannot change the size of logical partitions after they are divided. When a logical partition cannot store a certain file, this file cannot be stored across multiple partitions due to the limitation of the upper file system, so it cannot put it on another disk at the same time

When the space of a certain partition is exhausted, the solution is usually to use a symbolic link, or use a tool to resize the partition, but this is only a temporary solution and cannot fundamentally solve the problem
