Install centos on Soft Raid without a hardware RAID card

Labels: Install system soft RAID

I remember reading an Open Course in YY, where I installed the operating system on a soft RAID without a hardware RAID card. When a disk crashes, the entire system will not crash (raid1 ); I personally think it is quite fun, And I installed and tried it today. The following is the operation process. Because of obsessive-compulsive disorder, the whole process has been completed;

Lab environment:

VMware Workstation 10.0

Centos 6.4x64

When adding a virtual machine, I added two GB hard disks to the virtual machine;

1. Insert the disc and boot it. Use the graphical interface to install the system;
