修复 /dev/sda2 恢复日志时遇到问题

今天我看到 Ubuntu 正在清理孤立的 inode。以下是启动日志消息：

/dev/sda2: clearing orphaned inode 396229 uid=1000 gid=1000 mode 0100600 ,si
/dev/sda2: clearing orphaned inode 1300596 uid=1000 gid=1000 mode 0100600 ,si
/dev/sda2: clean 578019/30049216 files, 22460578/121120000 blocks

此外：

[FAILED] Failed to start Postfix Mail Transport Agent, instance -)

然后启动恢复。我多次重启系统，但日志各不相同。有时 Postifix 错误从不显示，有时它告诉我缺少 lowerdir，有时它只显示上面的前三行。经过进一步调查，我设法将错误定位到 /dev/sda2，但我似乎无法篡改它，即使作为超级用户也是如此。之后，我在文件系统上运行了部分 fsck，它告诉我：

fsck from util-linux 2.36.1

/dev/sda2: ********** WARNING: Filesystem still has errors **********

/dev/sda2: 578019/30049216 files (0.8% non-contiguous), 22460578/121120000 blocks


At this point, I have tried to umount the filesystem  to actually fix the error, but it tells me it's busy, even though I ran the "kill all processes command".I also tried to do it through grub shell prompt, with no luck either.I may be forgetting something (I'm still a beginner), but I would like some help with fixing this filesystem

此外，我更喜欢一种不需要实时 USB 的方法，只是因为我没有 USB，而且在我所在地区很难找到 USB，但我仍然愿意接受所有解决方案。

这恰当的检查/修复文件系统的方法...

  • 以“试用 Ubuntu”模式启动 Ubuntu Live DVD/USB
  • terminal按Ctrl+ Alt+打开窗口T
  • 类型sudo fdisk -l
  • 识别“Linux 文件系统”的 /dev/sdXX 设备名称
  • 输入sudo fsck -f /dev/sdXX，替换sdXX为您之前找到的数字
  • fsck如果有错误则重复命令
  • 类型reboot
