徵狀

如果 Windows Server 2012 或 Windows Server 2008 R2 Hyper-V 主機遇到非預期的重新啟動,而且虛擬機器正在使用連接至虛擬 IDE 控制器之虛擬硬碟上的磁碟區時,該伺服器上的虛擬硬碟將不再保持一致。

例如,假設您在 Hyper-V 主機伺服器上有虛擬化的網域控制站。當 Hyper-V 主機伺服器當機或發生電源中斷,Active Directory 資料庫可能會發生損毀,或是虛擬機器無法啟動,而您可能會收到類似下列的錯誤訊息:

c00002e2 目錄服務無法啟動,因為發生下列錯誤: %hs 錯誤狀態: 0x%x。請將系統關機,並重新開機成目錄服務還原模式,您可以檢查事件日誌,以取得詳細資訊。

發生的原因

這個問題是因為當來賓上的作業系統要求停用磁碟快取,Hyper-V 虛擬 IDE 控制器錯誤地報告成功。這可能會造成發出 I/O 作業的應用程式認為這些作業保留在磁碟上,但實際上位於磁碟快取上,因此在 Hyper-V 主機電源中斷後無法繼續保留。

注意 安裝此更新後,要求停用 Hyper-V 虛擬 IDE 控制器上的磁碟快取將會失敗。這是預期會發生的情況。您可能會收到來賓電腦作業系統中的 Active Directory 所產生的警告訊息。此事件 1539 警告訊息指出「Active Directory 網域服務無法停用下列硬碟上的軟體磁碟寫入快取」,後面跟著硬碟的磁碟機代號 。此警告訊息是在 Hyper-V 虛擬 IDE 控制器正確地拒絕停用磁碟快取時產生。不過,Active Directory 要求不使用快取而完成所有資料庫更新,如此 Hyper-V 儲存子系統才能防止因電源中斷或其他非預期的重新開機而造成資料遺失。
