在Ext4 5.8 64位上运行了一段时间后的CentOS自身错误

过了一段时间后才会发生这种事。服务器没有重新启动。所有磁盘都没问题。我在两个3TB驱动器上使用软件RAID1设置。我看不出有什么问题不稳定什么的。

有一次我在晚上运行了e4fsck。它纠正了所有tje错误，然后又开始发生，但是服务器根本没有重新启动。

有什么好担心的吗？

内核：

Answer 1

我不得不升级到内核3.X.X，在那里ext4工作得很好;)

Answer 2

是的，这是值得担心的事情。这意味着要么是某个东西破坏了您的文件系统，要么是其他东西破坏了您的文件系统。

主要嫌疑人将是你的磁盘本身。用smartctl检查它们：

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

下一个嫌疑人将是驱动控制器和电缆。
