synology升級失敗"此檔案可能已損毀"

 Synology的firmware太舊，管理程式也太舊，要在管理介面上用自動更新。

但卻一直顯示這個是最新版了，所以就手動去下載最新的版本來用手動更新。

結果下載好的檔案透過管理介面上傳後卻一直顯示此檔案可能已損毀。

試了幾個比較新的版本都如此。

然後查了一下才發現原本的版本太舊(6.2)，沒辦法直接7，要先下載6.3手動更新，更新完成後，自動更新的功能也恢復正常，就利用自動更新在升到最新版就行了。

Failed Synology upgrade: "This file may be corrupted"

The firmware on the Synology device is too outdated, as well as the management software. To perform an update, the automatic update option is selected within the management interface.

However, the system keeps showing that the current version is the latest, so the decision is made to manually download the latest version and perform a manual update.

After downloading the file, it is uploaded through the management interface, but an error message stating that the file may be corrupted keeps appearing.

Several newer versions are attempted, but the issue persists.

Upon further investigation, it is discovered that the original version (6.2) is too outdated to directly upgrade to version 7. It is necessary to first download version 6.3 and perform a manual update. After completing the update, the automatic update functionality is restored, allowing for an upgrade to the latest version using the automatic update feature.

QNAP TS-432XU(4.3.6)更換故障硬碟

 一台QNAP TS-432XU(4.3.6)有4顆硬碟做RAID5，最後一顆硬碟已出現警告建議更換，雖然還可以用，但這顆硬碟的讀寫速度慢很多，所以影響到一些日常作業。

原本同型號的硬碟停產了，所以就買一個同廠牌同容量，但轉速更快的來換。

雖然知道是熱插拔，但一開始還上網看一下是不是要在管理介面上做什麼操作，後來查到的畫面又跟自己的不同，就決定直接插拔更換了。

插上後系統就自己在重建了，蠻方便的，剩下就讓它跑完重建程序了。

Replacing a Faulty Hard Drive on QNAP TS-432XU(4.3.6)

On a QNAP TS-432XU(4.3.6) device with a RAID 5 configuration using four hard drives, the last drive started showing warning signs and advised replacement. Although it was still functional, its read and write speeds had significantly decreased, affecting daily operations.

Since the original model of the hard drive was no longer available, I purchased a higher-speed drive from the same manufacturer with the same capacity as a replacement.

While I knew that the device supported hot-swapping, I initially checked online to see if there were any specific actions required through the management interface. However, the instructions and screenshots I found were different from what I encountered, so I decided to proceed with a direct replacement.

Once I inserted the new drive, the system automatically initiated the rebuilding process. It was quite convenient, so I allowed it to complete the rebuilding procedure.

QNAP NAS無法發信 Failed to send a test message using SMTP Service.

在QNAP NAS設定好電子郵件設定，用來發送警告信給管理者，設定好後測試，卻都失敗，錯誤訊息就是示"Failed to send a test message using SMTP Service."。

從不同網段連到QNAP的管理web都正常，所以就覺得網路設定都沒問題。

後來就想用ssh連上QNAP，去ping在不同網段的mail server，卻是不通的，然後再執行route -n 顯示路由表時，卻沒有0.0.0.0的路由，這就妙了。

本來想直接用指令去加，但查到的指令route add default gw 192.168.24.1 br0有錯誤，所以就決定回管理web上看看是不是少設了什麼。

結果發現了一個東西，有一個系統預設閘道的設定，之前都沒去理它，後來進去這設定，在把gateway設定上去之後，回到ssh裡，route -n 顯示路由表時，就有0.0.0.0的路由，發送信件的功能也就正常了。

The QNAP NAS is unable to send emails.

When setting up the email configuration on the QNAP NAS to send alert messages to the administrator and testing it, all attempts fail with the error message "Failed to send a test message using SMTP Service."

Since accessing the QNAP management web interface from different networks works fine, it is believed that there are no issues with the network settings.

Later on, an attempt was made to connect to the QNAP using SSH and ping the mail server in a different network segment, but the connection was unsuccessful. Upon executing the command "route -n" to display the routing table, it was noticed that there was no route for 0.0.0.0, which was puzzling.

Initially, there was a plan to manually add the route using the command "route add default gw 192.168.24.1 br0," but it was found to be incorrect. Therefore, the decision was made to go back to the management web interface and check if anything was missing.

As a result, it was discovered that there was a default gateway setting that had been overlooked. Previously, it had not been addressed. After accessing this setting and configuring the gateway, upon returning to the SSH session and executing "route -n" to display the routing table, the route for 0.0.0.0 appeared, and the email sending functionality started working correctly.

QNAP NAS 取消 HOT SPARE硬碟，擴充到RAID

手邊有一台QNAP TS-432的NAS，有做RAID+HOT SPARE，但空間不足，HOT SPARE要拿來擴充到RAID裡面。設定流程:

1. 先到HOT SPARE設定的地方，將該硬碟取消勾選，就會取消這顆HOT SPARE。

2. 接著就去擴充，就會多一顆硬碟可以拿來擴充到原本的RAID磁區的裡面了。
