Symptoms

 

  • 在問題 SVM 的 ESXi 主機上，raid 控制器驅動程式lsi_mr3回報本機資料存放區底層磁碟中止，且 ESXi 回報失去磁碟區的存取權。

  • SDS 裝置可能會回報工作中止 （可在 var/log/messages 和 VMware 記錄中找到），因此此 SVM 上的 SDS 程序會經歷長時間的流動 IO，這會進一步影響 scaleio 系統的穩定性

 

  • SDC 接著會在 VMkernel 記錄中記錄 IO 錯誤，因為本機資料存放區的回應緩慢，使得有問題的 SDS 發生一些淨插槽問題，而 ScaleIO 磁碟區上的應用程式資料存放區可能會回報無法存取：

Impact

 

影響

SDC 可能無法存取位於 PowerFlex 磁碟區的資料存放區，而且這些資料存放區上的應用程式或虛擬機器可能會受到影響，例如檔案系統變成唯讀。
 

Cause

  • VMFS 資料存放區會透過以寫入作業的形式發出的活動訊號來監控，這些活動訊號大約每 3 秒會從主機發出一次到 VMFS 磁碟區。當 SVM 的本地數據存儲回應緩慢、檢測信號 I/O 的總時間未在 16 秒視窗內完成時，數據存儲將被標記為離線，並且 hostd 會生成無法訪問卷日誌消息以反映此行為。如需詳細資訊，請參閱 VMware KB 瞭解遺失的 ESXi 磁碟區訊息存取權 
  • 在這種情況下，將無法預測 SDS 的確切行為，例如會遺失哪些保活訊息，以及哪些其他 PowerFlex 元件。此 SDS 必須提供的某些 SDC IO 可能會超過作業系統或應用程式的逾時時間，造成影響。

Resolution

請聯絡 VMware 和硬體廠商，以修正 RAID 控制器或其韌體和驅動程式的問題。

Additional Information

暫時的因應措施是移除有問題的 SDS，或將其遷移至另一個良好的本機資料存放區。
