Fortifying Data: The Essential Guide to RAID Technology

Introduction to RAID: Understand the need for data redundancy and performance optimization in storage solutions.

Explanation of RAID Levels: Explore RAID 0, RAID 1, RAID 5, and other configurations, uncovering their advantages and use cases.

Step-by-Step Guide to Setting Up RAID 1 (Mirroring) in Linux:
Installing mdadm for RAID management.
Partitioning hard drives using fdisk.
Creating a RAID array with mdadm.
Formatting the RAID array with a chosen file system.
Mounting the RAID array for usage.
Making the RAID configuration persistent across reboots.
Verifying the RAID status and ensuring proper functionality.

Code Snippets and Commands Used:

bash

sudo apt update
sudo apt install mdadm
sudo fdisk /dev/sda
sudo fdisk /dev/sdb
sudo mdadm --create --verbose /dev/md0 --level=mirror --raid-devices=2 /dev/sda1 /dev/sdb1
sudo mkfs.ext4 /dev/md0
sudo mkdir /mnt/myraid
sudo mount /dev/md0 /mnt/myraid
sudo mdadm --detail --scan | sudo tee -a /etc/mdadm/mdadm.conf
sudo update-initramfs -u
cat /proc/mdstat
sudo mdadm --detail /dev/md0
