There are all kinds of problems in RAID1.

DELL R710 did a RAID1, but I didn't expect to encounter all kinds of problems:

1. There is no hard drive carrier, only the hard drive. Buy it!

two。 Hard disk in BIOS, do RAID 1, support up to 2T of data (each hard disk recognize half of the space). Each of my hard drives is 4T. That'll be $2.

My BIOS VERSION 3.0.0. Speechless.

Solution: use 2 4T hard drives as ordinary hard drives. Delete the RAID Array that has been done in BIOS, then enter the system, and you can see the 8T data. However, each disk (4T) is automatically divided into two partitions, namely D disk and E disk. I want the space of 4T to be on the same D disk, what should I do? Call the official hard drive (Seagate official) at 4008878790. Then report your hard drive SN number, and she will give you the knowledge of the hard drive. (the system is win 2008 R2)

Post the steps to solve the problem:

Step 1: diskpart

To the desktop of the computer

Press window key + R

Find "Run", "execute" and type "cmd". (or window key + R)

Enter "Diskpart".

Type "list disk" to find the drive letter you want to clean. (disk0, disk 1 will appear)

Enter "select disk 1" (1 is the representative number of the drive letter, you have to adjust it according to your drive letter.) .

Enter "Clean" and then do so.

Finally, "exit."

Step 2: initialize

To the desktop of the computer

Press window key + X

Click "disk Management"

Right-click "disk 1" (this is the column, you need to click according to the drive letter you confirmed earlier, or you may go directly to step 6)

Select initialize

Select "GPT"

Confirm

Right-click in the "unconfigured" range, and click "New simple Volume"

If you don't want to partition, click "next" until you finish.

To partition, enter the capacity, and then click next until you are finished

Let the system automatically complete the "formatting" process

3. I still need to find a hard drive to do RAID1. Then buy 2 more hard drives (each 2TMagol 7200 rpm, 128m Magazine SAS enterprise class). JD.com self-management, 7 days unconditional return.

My server is DELL R710, and I do a lot of articles on RAID 1, such as https://blog.csdn.net/zll_0405/article/details/78824223 and so on. But my method is not suitable for my server, and the way I finally found it is:

Experience: 2T data synchronization, too slow, I have done an experiment, more than 10 hours. When I went to see it the next morning, the synchronization was indeed completed, and the state of the RAID became Optimal (optimal). In general, it did synchronize automatically. (it is said in the article that if it is not synchronized, a hot disk will be configured, as is said in the article)
