Introduction

Setting up a RAID (Redundant Array of Independent Disks) configuration on your Ubuntu system can be a bit tricky, especially when dealing with large storage drives like 4TB. In this article, we will guide you through the process of setting up a RAID1 configuration on Ubuntu 24.04, which provides a mirrored copy of your data across two drives, ensuring data redundancy and high availability.

Understanding RAID1

RAID1 is a type of RAID configuration that involves mirroring data across two or more drives. This means that every block of data written to one drive is also written to another drive. This provides several benefits, including:

Data redundancy: If one drive fails, the other drive can take over and continue to provide access to your data.
Improved performance: RAID1 can provide improved read performance, as the system can read data from both drives simultaneously.
High availability: RAID1 can provide high availability, as the system can continue to operate even if one drive fails.

Hardware Requirements

Before we begin, make sure you have the following hardware requirements:

Two 4TB drives: You will need two 4TB drives to set up a RAID1 configuration.
A compatible motherboard: Your motherboard should support RAID1 and have the necessary hardware to support it.
A compatible Ubuntu system: You should be running Ubuntu 24.04 or later.

Software Requirements

In addition to the hardware requirements, you will also need the following software requirements:

Ubuntu 24.04: You should be running Ubuntu 24.04 or later.
mdadm: You will need to install the mdadm package to manage your RAID configuration.
udev: You will need to install the udev package to manage device events.

Step 1: Prepare Your Drives

Before you can set up a RAID1 configuration, you need to prepare your drives. This involves:

Formatting the drives: You will need to format the drives to a compatible file system, such as ext4.
Creating a partition table: You will need to create a partition table on each drive to define the layout of the drive.

Formatting the Drives

To format the drives, you can use the mkfs.ext4 command. This command will format the drive to the ext4 file system.

sudo mkfs.ext4 /dev/sdb1

Creating a Partition Table

To create a partition table, you can use the fdisk command. This command will create a new partition table on the drive.

sudo fdisk /dev/sdb

Once you have created the partition table, you can exit the fdisk command by typing w.

Step 2: Create a RAID1 Configuration

Once you have prepared your drives, you can create a RAID1 configuration using the mdadm command. This command will create a new RAID1 device and add the two drives to it.

sudo mdadm --create --verbose /dev/md0 --level=1 --raid-devices=2 /dev/sdb1 /dev/sdc1

This command will create a new RAID1 device called /dev/md0 and add the two drives /dev/sdb1 and /dev/sdc1 to it.

Step 3: Format the RAID Device

Once you have created the RAID1 configuration, you need to format the RAID device to a compatible file system, such as ext4.

sudo mkfs.ext4 /dev/md0

Step 4: Mount the RAID Device

Once you have formatted the RAID device, you need to mount it to a directory on your system.

sudo mount /dev/md0 /mnt

Step 5: Verify the RAID Configuration

Once you have mounted the RAID device, you need to verify that the RAID configuration is working correctly. You can do this by checking the status of the RAID device using the mdadm command.

sudo mdadm --detail /dev/md0

This command will display the status of the RAID device, including the number of active drives and the number of failed drives.

Conclusion

In this article, we have guided you through the process of setting up a RAID1 configuration on Ubuntu 24.04. This configuration provides a mirrored copy of your data across two drives, ensuring data redundancy and high availability. We have also covered the hardware and software requirements, as well as the steps to prepare your drives, create a RAID1 configuration, format the RAID device, mount the RAID device, and verify the RAID configuration.

Troubleshooting

If you encounter any issues during the setup process, you can try the following troubleshooting steps:

Check the drive status: Use the mdadm command to check the status of the drives.
Check the RAID configuration: Use the mdadm command to check the status of the RAID configuration.
Check the file system: Use the fsck command to check the file system for errors.
