Scenario
If your QNAP NAS does not support hot-swapping, hard drives must be replaced when the NAS is powered off. This article explains how to safely replace drives in such systems, particularly in a RAID 1 configuration—whether you are recovering from a disk failure or upgrading to larger drives.
Solution
Replacing a failed disk in RAID 1
If one of the disks in your RAID 1 storage pool has failed:
- Power off the NAS.
- Remove the failed hard drive and insert a new drive that has the same capacity or larger capacity.
Important
Do not use drives that were previously used in another QNAP NAS, PC, or Mac to avoid RAID metadata conflicts.
- Power on the NAS.
- QTS will detect the new drive and automatically start the RAID rebuild process.
You can monitor progress in Storage & Snapshots > Storage/Snapshots > Manage > Rebuild.
- Wait until the rebuild process is fully completed before performing any other operations. You can monitor the rebuild progress in "Background Tasks" on the Toolbar.
- You may also check the logs to confirm that the RAID rebuilding is finished.
Replacing both healthy disks to upgrade storage capacity
If you want to upgrade to drives of larger capacity:
- Back up all data from the NAS.
- Power off the NAS and replace both drives with new drives.
- Power on the NAS and initialize the system. This will create a new RAID 1 storage pool.
- Restore your data from the backup.
Note
You cannot expand RAID 1 capacity on a non-hot-swappable NAS by replacing one drive at a time. You must replace all drives and rebuild the RAID volume from scratch.
Migrating from RAID 1 to RAID 5 by adding a drive
If you want to change your setup from RAID 1 to RAID 5 by adding another drive:
- Ensure that the NAS supports RAID migration and the desired number of drives for RAID 5.
- Power off the NAS.
- Install the third hard drive (must have the same capacity or larger than the existing drives, and preferably a new drive).
- Power on the NAS.
- Open Storage & Snapshots and go to Manage > Migrate RAID Group.
- Follow the on-screen instructions to migrate from RAID 1 to RAID 5.
Recommendation
- The NAS must be powered off when you install new drives on non-hot-swappable models
- Always use brand-new hard drives for replacements.
- Avoid reusing drives from other QNAP systems or computers.
- Refer to the QNAP HDD Compatibility List to choose compatible models.
- Maintain regular backups before making any hardware changes.

適用產品
QTS, 儲存與快照總管, QNAP NAS (不支援熱插拔的型號)
情境
如果您的 QNAP NAS 不支援熱插拔，則必須在關機時更換硬碟。本文說明如何在此類系統中安全地更換硬碟，特別是在 RAID 1 配置中，無論是從磁碟故障中恢復還是升級到更大容量的硬碟。
解決方案
更換 RAID 1 中故障的磁碟
如果您的 RAID 1 儲存空間 池中的一個磁碟故障：
- 關閉 NAS 電源。
- 移除故障的硬碟並插入具有相同或更大容量的新硬碟。
重要
請勿使用先前在其他 QNAP NAS、PC 或 Mac 中使用過的硬碟，以避免 RAID 中繼資料衝突。
- 開啟 NAS 電源。
- QTS 會偵測到新硬碟並自動開始 RAID 重建過程。
您可以在儲存與快照總管 > 儲存空間/快照 > 管理 > 重建。
- 在執行其他操作之前，請等待重建過程完全完成。您可以在「背景任務」工具列上監控進度。
- 您也可以檢查日誌以確認 RAID 重建已完成。
更換兩個健康磁碟以升級 儲存空間 容量
如果您想升級到更大容量的硬碟：
- 備份 NAS 中的所有資料。
- 關閉 NAS 電源並用新硬碟替換兩個硬碟。
- 開啟 NAS 電源並初始化系統。這將創建一個新的 RAID 1 儲存空間 池。
- 從備份中還原您的資料。
註
在不支援熱插拔的 NAS 上，無法透過一次更換一個硬碟來擴充套件 RAID 1 容量。您必須更換所有硬碟並從頭開始重建 RAID 卷。
透過新增硬碟從 RAID 1 遷移到 RAID 5
如果您想透過新增另一個硬碟將設定從 RAID 1 更改為 RAID 5：
- 確保 NAS 支援 RAID 遷移和 RAID 5 所需的硬碟數量。
- 關閉 NAS 電源。
- 安裝第三個硬碟（必須具有與現有硬碟相同或更大的容量，最好是新硬碟）。
- 開啟 NAS 電源。
- 開啟儲存與快照總管並前往管理 > 遷移 RAID 群組。
- 按照螢幕上的指示從 RAID 1 遷移到 RAID 5。
建議
- 在非熱插拔型號上安裝新硬碟時，必須關閉電源
- 始終使用全新 硬碟進行更換。
- 避免重複使用來自其他 QNAP 系統或電腦的硬碟。
- 請參考 QNAP HDD 相容性清單以選擇相容的型號。
- 在進行任何硬體更換之前，請保持定期備份。
