對 RAID1 的所有驅動器的 SMART 短離線測試永不結束
我在這裡遇到了一個奇怪的情況。在低流量伺服器中使用了大約三年後，RAID1 中的兩個三星驅動器之一昨天發生了故障：
Personalities : [raid1] md0 : active raid1 sdb1[2](F) sda1[0] 732572608 blocks [2/1] [U_]由於 smartd 沒有報告任何內容，我檢查了 smart 屬性，與 sda 相比，sdb（失敗）上唯一的可疑讀數是：
sda: 191 G-Sense_Error_Rate 0x0022 252 252 000 Old_age Always - 0 sdb: 191 G-Sense_Error_Rate 0x0022 098 098 000 Old_age Always - 27650伺服器機架中的 G-sense 錯誤？可能是感測器壞了？
但是兩個驅動器上還有另一個時髦的讀物：最新的短離線測試是“中斷（主機重置）”，如果我開始一個新的測試，例如使用
smartctl --test=short /dev/sda，選擇性自檢日誌顯示：SPAN MIN_LBA MAX_LBA CURRENT_TEST_STATUS 1 0 0 Self_test_in_progress [90% left] (0-65535)然而，這個簡短的測試永遠不會結束，即使幾個小時後，情況仍然是一樣的——在兩個驅動器上。這可能是驅動器上的韌體錯誤嗎？還是控制器出現故障？
這是兩個驅動器的完整轉儲，每個驅動器都執行了一個簡短的自檢：

控制器錯誤似乎在這裡。在您花費太多時間之前，我建議您重新安裝所有電纜。隨著時間的推移，某些東西可能會鬆動，並導致問題。
另外，您提到了 smartd …您在嘗試執行自檢時是否禁用了此功能？這可能會干擾手動測試。
有什麼
dmesg關於為什麼 sdb 被認為是失敗的嗎？兩個驅動器似乎都將它們的健康狀況報告為通過，我不相信 mdadm 實際上使用任何 SMART 數據來確定驅動器的健康狀況。
