Gibson, Randy Katz 于1987年在加州大学伯克利分校发明的。在1988年6月SIGMOD会议上提交的论文"A Case for Redundant Arrays of Inexpensive Disks"(中文翻译:廉价磁盘冗余阵列案例)中提出。为了提升磁盘系统性能,他们提出用许多块廉价的 Linux 包管理器 网络协议 磁盘管理 Linux系统磁盘管理 Linux文章目录Linux1. 磁...

Btrfs支持快照、数据压缩、数据校验和自愈能力、RAID(Redundant Array of Independent Disks)等功能。它具备高性能、可扩展性和容错性,并支持在线文件系统扩展和收缩。Btrfs的目标是为Linux系统提供一个灵活、可靠且易于管理的文件系统选项。 在日常的运维管理中,有一些常用的命令用于文件系统的管理操作,如下所示: df...

In this chapter, we’ll discuss in detail how to work with disks on a Linux system. You’ll learn how to partition disks, create and maintain the filesystems that go inside disk partitions, and work with swap space. 在第三章中,我们讨论了内核提供的一些顶层磁盘设备。 在本章中,我们将...

This will give you a list of disks that are connected to your computer. The next step is to create a new MBR partition table on both hard drives. However, before doing this, you need to back up important data on these hard drives. After all, the formation and creation of a new MBR...
