这种情况只是在一段时间后才发生的。服务器没有重新启动。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。
有一次我在晚上运行了 e4fsck。它纠正了所有错误，然后又开始发生这种情况，但服务器根本没有重新启动。
有什么需要担心的吗？

答案1
是的，这确实值得担心。这意味着要么有什么东西正在破坏你的文件系统，要么有其他什么东西正在破坏你的文件系统。
首要怀疑的是你的磁盘本身。使用以下命令检查smartctl：
smartctl -a /dev/sda
smartctl -a /dev/sdb
下一个怀疑对象是驱动器控制器和电缆。
答案2
我必须升级到内核 3.XX，这样 ext4 才能正常工作；）
