Replacing a Failed Hard Drive in Synology NAS RAID Arrays: A Comprehensive Guide
When a hard drive fails in your Synology NAS RAID array, swift action is crucial to prevent data loss and ensure the continued operation of your system. In this guide, we will walk you through the step-by-step process of replacing a failed hard drive in your Synology NAS RAID setup.
Step 1: Identify the Failed Hard Drive
The first step is to identify which hard drive has failed in your Synology NAS. Log in to the DiskStation Manager (DSM) interface and navigate to Storage Manager to view the status of your drives. The failed drive will be marked as ‘Failed’ or ‘Degraded’.
Step 2: Power Down the Synology NAS
Before replacing the failed hard drive, it is important to power down the Synology NAS properly. Go to Control Panel > Hardware & Power > Power and initiate a system shutdown.
Step 3: Replace the Failed Hard Drive
Once the NAS is powered down, locate the failed hard drive and carefully remove it from the drive bay. Insert the new hard drive into the same bay and ensure it is securely in place.
Step 4: Reboot the Synology NAS
Power up the Synology NAS and log in to the DSM interface. Navigate to Storage Manager and click on ‘Repair’ to initiate the RAID rebuilding process with the new hard drive.
Step 5: Monitor the RAID Rebuilding Process
It is essential to monitor the RAID rebuilding process to ensure that it completes successfully. Check the Storage Manager regularly to track the progress and verify that the new hard drive is functioning properly.
Tips for Successful Hard Drive Replacement:
- Always have a spare hard drive on hand for quick replacement.
- Backup your data regularly to prevent data loss in case of multiple drive failures.
- Follow manufacturer’s guidelines for compatible hard drives for your Synology NAS model.
By following these steps and tips, you can effectively replace a failed hard drive in your Synology NAS RAID arrays and maintain the integrity of your data storage system. Remember to prioritize data backup and system maintenance to safeguard against future failures.
