4412核心板，安装了ubuntu系统，文件系统损坏变为只读该怎么处理？

~ # mount -o rw.remount /mount: can't read '/etc/fstab': No such file or directory~ # ~ # lsls: ./fa-network-service: Input/output errorls: ./logmsg: Input/output errorls: ./Settings: Input/output errorbin         dev         home        linuxrc     mnt         proc        sbin        sys         udisk       vardata     


同时fstab文件不见了

This post perfectly captures a frustration I've definitely faced. I once had a similar issue with an embedded system, where a power cut corrupted the filesystem, rendering it read-only. It’s like hitting a brick wall when you can't even remount. For a bit of distraction while troubleshooting, I often turn to games like Heardle, but getting that system back online was a real head-scratcher. Eventually, a complete re-flash was necessary. It really highlights the importance of robust error recovery.
