Mdadm is used for managing MD (multiple devices) devices, also known as Linux software RAID. Now we have two raid devices /dev/sdb1 and /dev/sdc1. Type p again to check the partition type.įollow the same instruction to create a Linux raid autodetect partition on /dev/sdc.Enter fd to set partition type to Linux raid autodetect.We need to change the partition type, so type t.Typing p will print information about the newly created partition.This partition will span across the entire drive. Press Enter to choose the default last sector.Press Enter to choose the default first sector.Next, use the fdisk command to create a new partition on each drive and format them as a Linux raid autodetect file system. You can create GPT partition table by replacing msdos with gpt, but for the sake of compatibility, this tutorial will create MBR partition table. Make sure your data is backed up.) sudo parted /dev/sdb mklabel msdos (Note: this is going to wipe out all existing partitions and data from these two hard drives. Then run the following 2 commands to make new MBR partition table on the two hard drives. You can see mine is /dev/sdb and /dev/sdc. Run the following command to check the device name. Insert two hard drives into your Linux computer, then open up a terminal window. And finally create the RAID 1 array using the mdadm utility.Next, we will create special file systems on /dev/sdb and /dev/sdc.
Remember to back up your existing data before formating your hard drives. These two hard drives can be of different sizes. Then you are going to grab two hard drives which will be named /dev/sdb and /dev/sdc in this post.In this tutorial we will name it /dev/sda. First you need to have a Linux distribution installed on your hard drive.Basic Steps to Create Software RAID 1 on Linux Software RAID requires you already installed an operating system.

You can install an operating system on top of hardware RAID which can increase uptime. When you boot up the computer, you are going to see an option that allows you to configure the RAID. Then you connect your hard drives to this card.
A hard drive controller is a PCIe card that you put into a computer. To set up RAID, you can either use a hard drive controller, or use a piece of software to create it. If your two hard drives are both 1TB, then the total usable volume is 1TB instead of 2TB. The downside of RAID 1 is that you don’t get any extra disk space. You can pull the failed hard drive out while the computer is running, insert a new hard drive and it will automatically rebuilds the mirror. The nice part about RAID 1 is that if one of your hard drive fails, your computer or server would still be up and running because you have a complete, intact copy of the data on the other hard drive. If you have two hard drives in RAID 1, then data will be written to both drives. Here we will discuss about RAID 1 which is also known as disk mirroring. There are many RAID levels such as RAID 0, RAID 1, RAID 5, RAID 10 etc. RAID allows you to turn multiple physical hard drives into a single logical hard drive. RAID stands for Redundant Array of Inexpensive Disks. In this tutorial, we’ll be talking about RAID, specifically we will set up software RAID 1 on a running Linux distribution.
