我有一个由逻辑卷组成的 ext3 分区。卷组 (8 TB) 由 3 个 PV (1* 4TB、2* 2TB) 组成。 ext3 分区是该卷组中的唯一分区。
我在 Manjaro linux 上使用 fstab 将此分区挂载到文件夹 (/plex_media/) 中。一切都会按预期启动并加载。但是，当我突然开始复制内容时，分区似乎被重新安装为只读。我可以在 dmesg 中看到这一点（输出粘贴在下面），但我对 dmesg 的经验不足，无法解释这些消息。
所有磁盘都启用了 SMART，并且没有显示错误（如下所示）。我已经删除了日志并使用tunef2s和e2fsck重写了它。由于 dmesg 中所有 SATA 链路断开消息，我感觉这可能是电缆问题，但我真的不知道它们的含义，也不理解在线解释。
我不知道该怎么做。我看不出设置有什么问题。任何见解将不胜感激。

答案1
修正了这个错误。结果发现 SATA 端口 5 不起作用。我只是更换到另一个端口，现在运行良好。没有关于 SATA 链路断开的 dmesg 消息。由于重新挂载为只读，硬盘被标记为有错误，因此必须运行 fsck，结果没有返回任何错误！
