RAID systems are designed to provide performance and redundancy, but when they fail, they introduce complexity. This episode focuses on how to troubleshoot issues within various RAID configurations, such as identifying a degraded array in RAID 5 or dealing with a rebuild failure in RAID 10. We walk through the typical symptoms, such as missing volumes, excessive rebuild times, or inconsistent parity calculations.

We also explain the importance of knowing your array’s health before initiating a rebuild and why choosing the wrong drive order can compromise data integrity. The A Plus exam may test your understanding of what happens when specific drives fail in different configurations, so we provide real-world examples to help you visualize cause-and-effect relationships.
