zfs zpool 降級驅動器失去

  • March 3, 2016

我有一個降級的 zpool，稱為在 2 個鏡像中儲存 4 個 6TB 驅動器。第二個鏡像上的一個驅動器不可用。所有電纜似乎都已物理插入。我的設備ID有變化嗎？

zpool 狀態 -v 儲存

edit2 沒有意識到一個磁碟甚至沒有出現。看起來鏡像 1 中的第二個驅動器完全死了。sudo lshw -class 磁碟的輸出幫助我看到了這一點。

好吧，輸出清楚地表明其中一個驅動器是 250GB。它要麼被替換，要麼在它開始錯誤地報告它的空間時以某種方式損壞。使用 smartmontools並使用 進行檢查smartctl，它將顯示有關它的所有資訊。
