Linux 上的 ZFS - 設備故障後的意外行為

我維護一個帶有 ZFS 儲存池 (RAID Z3) 的 Debian 伺服器。最近 ZFS 報告了兩個磁碟同時發生故障：

ZFS has detected that a device was removed.

impact: Fault tolerance of the pool may be compromised.
   eid: 138

  host: serres-west-wing

生成這些消息後，熱備用已啟動並立即開始重新同步。重新同步後池的狀態如下：

ZFS has finished a resilver:

磁碟似乎已連接並且工作正常d0-part1。d1-part1

這是由於與磁碟降級無關的因素導致的錯誤嗎？兩個工作磁碟似乎不太可能同時發生故障。停用熱備件是否安全？

似乎磁碟斷開是由電源問題引起的。為機器升級 UPS 後，我沒有遇到任何問題。我已停用熱備件已停用

zpool detach datapool hs-d0-part1

然後我重新銀化了游泳池

zpool scrud datapool

將池恢復到其原始狀態。
