Easily implement RAID1 disk array in Linux

Article Title: RAID1 disk array can be easily implemented in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

RAID disk arrays have been applied in many companies! Especially in companies that are very important to data!

RAID disk arrays not only speed up Data Writing and access (RAID0), but also ensure data redundancy and recover data quickly when a disk fails!

RAID with data redundancy: RAID 1 and RAID 5.

Before testing, check if the system has the following software package: mdadm-2.6-1.i386.rpm. if not, it can be easily downloaded from the Internet. I don't know whether the CD is installed, but I installed the linux 9.0 server version. no installation is performed by default! :)

Okay. Let's take a look at how to implement the RAID array in linux! : P

1. I have created three M hard disks in the VM for experiment, as shown in:

2. Install the mdadm package, as shown in:

3. Use the fdisk command to initialize three new hard disks, as shown in:
