今天我尝试关闭我的一个 VirtualBox 系统，几分钟后我又一次遇到了同样的错误。然后我就强制关机了。
我记得我把那个分区从 50G 调整到了 100G。看起来它确实resize2fs运行正常。我想知道的是如何测试分区大小是否正确？没有 LVM。我只有一个分区（/dev/sda2），虽然 grub 在 中使用了一些东西/dev/sda1。
我能够在 kill 之后成功关机，因为我想用 进行测试fsck。但这没有给我任何信息。它说一切都很好。我还用 GParted 检查了一下，一切看起来都很好……
文件系统是ext4。
以下是 GParted 的输出查看命令：

知道为什么会发生错误以及我的数据是否存在风险吗？
