The Linux kernel provides a mechanism for accessing kernel internal data structures and changing kernel settings through the/proc file system at run time. Although the basic concepts of the/proc file system for Linux systems on va

attempts to assign pages to the process that sent the page request The partner system allocates memory pages: Page Frame Reclamation: When a process requests a specified number of memory pages without available memory pages, the kernel attempts to release a specific memory page for use by the new request, which is called memory reclamation. KSWAPD Kernel threads and try_to_free_page () kernel functions are responsible for page recycling.K

The basic structure of the linux System and the structure of the file system (configuration illustration) the linux system includes four major sections of the vLinux kernel v Linux Shel

With the evolution of high-performance computing from traditional host to networked cluster, the traditional host-based storage architecture has gradually developed to networked storage, and the trend of computing and storage separation is becoming more and more obvious. A new file system for Linux clusters has been launched internationally for the lack of SAN an

We recommend that you use a Linux mount file system. For example, you may have some knowledge about the Linux mount file system. Then, we will give a full introduction to the Linux moun

1. Disks are an important part of the Linux system. One of the most important tasks for system administrators is to manage their own file systems. First introduce some basic concepts of the following disks:1) sector is the smallest physical storage unit with 512 bytes per sector2) The sector is composed of a circle, wh

used, use the Swapon command to specify the swap file to be enabled;(6) You can use Swapon-s to check the usage of swap;Example 1 is as follows:(1) Use partition as swap·Fdisk/dev/hda· Input N; create a new partition. If the previous example is used, the hard disk should have space left. Here, create a m partition;· Input t; then input 7 (the new partition here is hda7, which can be viewed by P); input 82 (82 indicates that it is set to swap partitio

#whereis find software that is already installed Looking up a file on Linux is a bit of a hassle. After all, in Linux we need to use the dedicated "find" command to find the files on the hard disk. Inux file expression format is very complex, unlike Windows,dos under the u

, that is,/dev/sda1. In Fedora, we can see from df-h that Fedora is located in/dev/sda1. Therefore, in the configuration file that directs Fedora, there is also a line to specify where the root of Fedora is, on/dev/sda1; because/dev/hda7 has been virtualized to/dev/sda1. I understand this time; A file system that uses image files as virtual

...... /Usr partition: usr has been used since then. the figure at the beginning of the article is formed after mounting linux bin lib src. Does it look like hanging up? Note: 1. the mount point must be a directory. 2. a partition is mounted to an existing directory. the directory cannot be empty, but the contents in the directory are unavailable. This is also true for mounting file systems created by othe
