errors=remount-ro不会伤害你的系统,事实上,它在防止系统受到进一步的伤害,因为不允许对已经损坏的文件系统进行写操作。

来自man ext4


 errors={continue|remount-ro|panic}


 Define the behavior when an error is encountered. (Either


 ignore errors and just mark the filesystem erroneous and con‐


 tinue, or remount the filesystem read-only, or panic and halt


 the system.) The default is set in the filesystem superblock,


 and can be changed using tune2fs(8).
