今天去幫客戶排除某架 Hyper-V VM 處於 Paused-Critical 的問題

VM FT01 運作於 HYPERV01 上, 且該 VM 每 5 分鐘複寫到 HYPERV02

首先我先查看硬碟與硬碟陣列或者是 Storage Space 是否有任何異常，經查看後認為硬體應該目前無異常

在 Hyper-V 管理員畫面中看到該 VM 呈現 Paused-Critical
查看其複寫狀態，發現複寫失敗
而複寫功能會仰賴差異快照的傳送
若差異快照未能傳送
則會一直存放在 Storage 中
直到複寫成功後，系統才會將差異快照合併入 VHD/VHDX 中，並刪除差異快照
而此案由於該 VM 自 09-04 起未能複寫成功，導致其中一組磁碟空間耗盡

首先嘗試手動重新啟動複寫，失敗
接著取消複寫功能，取消複寫時，系統會將差異快照合併入 VHD/VHDX，但發生合併中斷
接著再手動重啟合併，經過 10 分鐘左右合併成功了。
接著讓該 VM 繼續運作。

最後設定該 VM 於指定時刻重新啟動複寫功能。

Log 節錄

首先要知道 Log 的名稱
顯示名稱與實際名稱可能會不同
Event Viewer 中的 Log 顯示名稱是: Microsoft-Windows-Hyper-V-VMMS/Admin
但實際 LogName 是 Microsoft-Windows-Hyper-V-VMMS-Admin

用以下指令可以撈出 LogName：

PS >(Get-WinEvent -ListLog * -ErrorAction SilentlyContinue).LogName | Where-Object { $_ -like "*VMMS*" }
Microsoft-Windows-Hyper-V-VMMS-Storage
Microsoft-Windows-Hyper-V-VMMS-Operational
Microsoft-Windows-Hyper-V-VMMS-Networking
Microsoft-Windows-Hyper-V-VMMS-Admin

使用以下指令撈出自 09-04 後 Microsoft-Windows-Hyper-V-VMMS-Admin 的所有 Log 到 CSV 檔案並節錄部分 Log 於後方：

1. 設定你想篩選的時間點（請依需求修改日期與時間）

$TargetTime = Get-Date "2026-09-04 00:00:00"

2. 透過 Hashtable 建立篩選條件並執行

$Filter = @{
    LogName   = 'Microsoft-Windows-Hyper-V-VMMS-Admin'
    StartTime = $TargetTime
}

3. 指定出 TimeCreated, Id, Message 三個欄位匯到 CSV 檔案

Get-WinEvent -FilterHashtable $Filter -ErrorAction SilentlyContinue | 
    Select-Object TimeCreated, Id, Message | 
    Export-Csv -Path "C:\HyperV_VMMS_Logs.csv" -NoTypeInformation -Encoding UTF8
