Virtual Machine RAID 5 build trainer-implementation process based on mdadm

Linux Kernel supports RAID and mdadm, an open source array management software. Therefore, we can implement RAID in linux or embedded linux. For most people who want to practice RAID, it is unrealistic to purchase a few hard disks to do experiments, and the virtual machine can solve this problem very well, with a little mouse, easy + Free. Refer to some resources on the Internet today

Today, based on some information on the Internet, we have successfully built the mdadm-based RAID 5 on virtual machines. I think this experiment is very suitable for teaching experiments.

Lab Platform

Windows XP + vmwarevm + FEdOra 8

Step 1 Add a hard disk

(Just like you have bought a few hard disks and inserted them on the machine)

Click Edit Virtual Machine Settings-Add. The add hardware wizard is displayed"

Select a SCSI hard disk

Set capacity

After that, add three more hard disks in the same way. For example, I have added four hard disks in total.

Note: When setting hard disk capacity, you can choose to increase with data or allocate immediately. Of course, you can choose to increase with data so that virtual hard disks do not occupy your hard disk space.
