我的系统中出现了一个非常奇怪的问题。
使用 debian linux：
我的系统通过主硬盘和辅助硬盘非常正常地启动。突然我的辅助硬盘出现故障，出现一些 I/O 错误 DRDY UNC 错误，这往往导致我的主 SDA 变成只读文件系统。
- 如何避免主目录被更改为只读
- 我需要执行哪些步骤才能从系统中删除 SDB 引用
是否有可能检测到 SDB 从系统中删除
- 我没有注意到 SDA 成为只读文件系统的任何内容

答案1
sdb 失败了，如下行所示：
[sdb] 添加。感知：未恢复的读取错误 - 自动重新分配失败
您需要确保所有数据都已备份，然后更换驱动器。为了保险起见，请使用驱动器制造商的工具检查系统中的所有其他驱动器，看看它们是否有问题。
从您发布的内容来看，我无法判断 sda 发生了什么。但是当驱动器开始出现故障时，整个系统冻结是很常见的。或者两个驱动器连接的 IDE 或 SATA 控制器挂起。这两种情况都可能导致它检测到文件系统错误，并切换到只读模式以试图防止任何损坏。
