在 CentOS 5.8 64 位上一段時間後，Ext4 出現自我錯誤

我在 dmesg 中收到這樣的警告：

這只是在一段時間後發生。伺服器沒有重新啟動。所有磁碟都很好。我在兩個 3TB 驅動器上使用軟體 RAID1 設置。我沒有看到任何問題、不穩定或其他問題。

有一次我在夜間執行了 e4fsck。它糾正了所有 tje 錯誤，然後它又開始發生，但伺服器根本沒有重新啟動。

有什麼需要擔心的嗎？

核心：

2.6.18-308.4.1.el5 #1 SMP Tue Apr 17 17:08:00 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux

我必須升級到核心 3.XX，其中 ext4 工作得很好；）

是的，這是值得擔心的事情。這意味著要麼有什麼東西破壞了你的文件系統，要麼有什麼東西正在破壞你的文件系統。

主要嫌疑人將是您的磁碟本身。檢查它們smartctl：

smartctl -a /dev/sda
smartctl -a /dev/sdb

下一個嫌疑人將是驅動控制器和電纜。
