Ext4错误和磁盘重新装入只读

Question

有时，我有一个错误的ext4和我的磁盘变成只读。

我可以用重新启动和fcsk /dev/sda2修复它，但它总是回来.

下面是一些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

是否应该删除或更改remount-ro中的fstab并忽略此错误？如何修复/避免此错误？

您能检查磁盘上的坏扇区或坏块吗？您可以使用坏块或smartctl命令在linux中签入，我认为坏磁盘只是造成问题的原因。
