Linux UNIX system learning experience

Linux is a very good file system, so I studied the Linux UNIX system and discussed it here. I hope it will help you. In the early 1990s S, I spent a lot of money on the computers I used at that time to purchase a large capacity of 80 MB.) hard disk, since then, I am always fascinated by file systems and hard disks. What makes me happy is to transfer large data blocks back and forth through the bus, read and write a large number of files, and perform standard checks.

Maybe you are not as addicted to hard disks and software that tracks files and directories as I do, however, you are at least concerned about how to secure and efficiently use the drive, and how to squeeze as much performance as possible from the poor I/O subsystem of the system. Yes, I call it "poor ". Unless you have a large amount of money to purchase unusual hardware, the progress in the disk I/O subsystem is very small compared with the CPU, RAM, and display card devices. The famous Moore's law does not apply here. It applies only to micro-magnetic and advanced manufacturing processes.

As the most widely used operating system, Linux has the best support for different file systems. Linux, unlike other Linux UNIX systems, traditionally only supports their local file systems and the CD-ROM file systems used in standard ISO-9660. My Fedora Core 4 system has a load-type kernel module that supports more than 20 file systems. They are mainly used to provide good compatibility. You can insert a disk to almost any other system and operate it in Linux. However, if you are adding another disk to the Linux system and do not want it®QNX, Mac OS X, or Minix communications, what should we do?

At least you need to know some basic knowledge about common Linux file systems, such as ext2 Second Edition extension file systems) and ext3 Third Edition extension file systems) and ReiserFS 4 are interesting and advanced file systems that support many unique features that can improve the system's file processing capabilities ).

If your Linux distribution does not support Reiser4 such as Arch, Linspire, or SUSE, You need to recompile your kernel. How to re-compile the kernel can be used as a separate tutorial. You need to find the "How-to" article in the distribution version used, it will guide you through the steps required to re-compile the kernel.
