HP P840 HDD RAID 5 許多奇怪的驅動器故障
我已經在我的 HP P840 上使用 RAID5 硬碟儲存 (8x6TB) 大約 2 年了，而且它總是出現異常多的驅動器故障。半年來一切都很好，但現在驅動器以一種奇怪的方式出現故障。例如，2 個新驅動器在添加到 RAID 幾天后出現故障。我也已經更換了 RAID 控制器，並且正在主機板和 RAID 控制器上使用最新的韌體。
我也嘗試過使用不同的驅動器。最初在該 RAID 中使用了 HGST DeskStar 6TB 驅動器，現在我在更換故障驅動器時已將它們替換為 HGST UltraStar 6TB。但是行為是一樣的。
此外，似乎（大多數）驅動器並沒有真正發生故障，因為一旦我更換了 RAID 控制器，一個故障驅動器就會再次被辨識為正常並開始重建。
我的主機支持人員說問題是我實際上使用的是 RAID5，我應該改用 RAID10。我很難相信，因為我一直在使用 RAID5 在其他系統上沒有問題（多年來沒有驅動器故障）。
誰能給我一個提示，罪魁禍首可能是什麼？RAID 控制器的配置方式有問題嗎？
謝謝！
*編輯：
伺服器是 HP DL180 G9
驅動器故障原因始終是“寫入重試失敗”*
更新：我們的主機讓我們完全更換硬體並切換到 RAID6。我們做到了，現在它已經順利執行了一段時間。雖然這並沒有真正調查，但我相信 shodanshok 對穿孔陣列的解釋似乎是合理的。因此我會接受這個答案。謝謝大家！

您可能有一個嚴重穿孔的陣列，由於條帶重建失敗，這會導致替換磁碟過早“計劃死亡”。您可以在此處和此處閱讀更多資訊
解決方案是備份、銷毀陣列、重新創建陣列並從備份中恢復。
下次避免使用具有如此大驅動器的 RAID5 陣列。我強烈建議使用 RAID6，甚至更好的是 RAID10。
您應該使用具有系統中磁碟大小和類型的 RAID6。但是，在 HP Smart Array RAID 控制器上執行 RAID5 本身並沒有錯。我認為您的問題是在未經伺服器硬體認證的設置中使用消費磁碟的結果。
不過，有關伺服器的一些詳細資訊可能會有所幫助。
這是 HPE 伺服器，還是您只是使用 HPE 控制器？
這些似乎不是 HPE 驅動器或 HPE 驅動器載體。這是一個不好的跡象。
hpssacli您提供的輸出還將顯示磁碟故障的原因。如果您不在 HPE 伺服器上並且存在背板問題或 SATA 超時（注意到您在 SATA 磁碟上），您可能會收到誤報。範例：（參見最後失敗原因行）：
