有时我有一个错误 ext4，我的磁盘变成只读的。
我可以通过重新启动来修复它，fcsk /dev/sda2但它总是会回来......
这里有一些dmesg：

我的/etc/fstab：
UUID=9c882ba5-b980-4f7d-dd02-cd0a1831ab1a / ext4 errors=remount-ro 0 1
UUID=0E37-D0A2 /boot/efi vfat umask=0077 0 1
/swapfile none swap sw 0 0
我应该删除或更改remount-ro并fstab忽略此错误吗？如何修复/避免此错误？
你能检查你的磁盘是否有坏扇区或坏块吗？您可以使用badblocks或smartctl命令检查 linux，我认为坏磁盘是您问题的唯一原因。
