Image: Replacing a Failed Drive in an mdadm Array on Ubuntu

The image is a wide, landscape-oriented banner illustration designed to introduce a technical blog post titled "Replacing a Failed Drive in an mdadm Array on Ubuntu." The overall style is clean and friendly, using a modern flat-illustration look rather than photorealism, which makes the concept approachable even for readers who are new to server administration. The background blends deep purple and warm orange gradients, giving the scene energy while still feeling professional.

At the top of the image, the title text is large and easy to read. The words "Replacing a" and "in an" are in white, while "Failed Drive" and "mdadm Array" are highlighted in orange, drawing attention to the key technical ideas. On the right side of the title sits the Ubuntu logo in orange and white, clearly establishing the operating system context without including any version numbers or commands that could become outdated.

The left side of the illustration shows a simplified server chassis with multiple front-facing drive bays. Several of the bays glow green, indicating healthy components. One drive is shown partially removed from the server and is marked with a bold red "X" to represent a failed disk. Another drive nearby is colored red and cracked, with an exclamation mark on it, reinforcing the idea of hardware failure. These visual cues communicate the problem state immediately without requiring any technical background.

In the center of the image, a stack of stylized database cylinders represents the RAID array. One of the middle segments is highlighted in red, symbolizing degraded redundancy or a problem inside the array. Beneath the cylinders is a short string of binary digits, purely decorative, suggesting data activity without tying the illustration to any specific configuration or implementation details.

A curved orange arrow flows from the left side of the image toward the right, visually guiding the reader through the process of replacing the failed disk. On the right side of the arrow is a clean, intact hard drive icon marked with a green checkmark, clearly representing the healthy replacement drive. This contrast between red failure symbols and green success symbols provides a simple narrative: something broke, and now it has been fixed.

On the far right, a laptop is shown with a dark terminal-style screen. The terminal lines are generic blocks rather than real commands, intentionally avoiding specific syntax so the image remains accurate over time. The laptop suggests the administrative work involved in rebuilding or managing the array, while staying abstract enough to fit many workflows.

Overall, the image communicates the story of identifying a failed disk, removing it, inserting a new one, and restoring a RAID array under Ubuntu. It balances technical credibility with visual clarity, making it suitable as a hero banner for a tutorial or guide without risking outdated or misleading specifics.
