The NAS cabinets (Network Attached Storage) are an efficient solution for centralized storage in business and home networks. However, they are not without problems. NAS disk errors can be caused by hardware failure, incorrect settings, or outdated firmware. In this article, we explore the most common issues, how to diagnose them, and best practices for troubleshooting them.

Diagnosing Common Problems

Common mistakes and how to identify them

• «Disk not detected»: This problem is usually caused by physical failures or faulty connections.
  Example: On a Synology NAS, a disk stopped working after three years of continuous use. The solution was to replace it and activate the RAID to protect data.
• Slow performance: Occurs when the disk operates near its maximum capacity.
  Solution: Eliminate redundant data or migrate information to backup storage.

Incorrect Configuration

Errors in initial configuration are also a common cause of failures.
Example: An ITCS client with a QNAP NAS experienced long access times due to the selection of an inappropriate protocol (SMB rather NFS) for your Linux environment. After adjusting the settings, performance improved by 50%.

Firmware and Software Update

Outdated firmware can cause system errors.
Example: A WD My Cloud NAS presented errors in the system logs that were resolved with an update. Keeping the firmware up to date optimizes performance and prevents problems.

Using Unsupported Disks

Installing generic drives in a NAS environment can lead to recurring failures.
Recommendation: Uses drives designed specifically for NAS arrays, such as the WD Red either Seagate IronWolf.

Preventive Measures

• Perform periodic maintenance:
  • Monitor the status of your disks with tools like SMART.
  • Clean the fans to prevent overheating.
  • Review network usage to avoid overloads.
• Enable RAID configurations to protect your data.
