在 CentOS 5.8 64 位上运行一段时间后出现 Ext4 自身错误

  • 772

我在 dmesg 中收到这样的警告：

这只是在一段时间后发生的。服务器未重新启动。所有磁盘都很好。我在两个 3TB 驱动器上使用软件 RAID1 设置。我没有看到任何问题、不稳定或其他问题。

有一次我在夜间运行了 e4fsck。它纠正了所有 tje 错误，然后又开始发生，但服务器根本没有重新启动。

有什么可担心的吗？

  1. 是的，这是值得担心的事情。这意味着要么有什么东西在破坏你的文件系统，要么有什么东西在破坏你的文件系统。

    主要嫌疑人将是您的磁盘本身。检查它们smartctl：

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

    下一个可疑点是驱动控制器和布线。

    我不得不升级到 ext4 工作正常的内核 3.XX ;)
