我有一个用于备份的 USB 驱动器，并且我必须扩展一个在启动时使用 /etc/fstab 中的正确行安装的分区。
启动 gparted 时，我遇到的第一个问题是无法从 gparted 卸载分区：尝试执行此操作时，我立即发现它再次被安装，并且 gparted 不允许我对该分区执行任何操作。
在我看来，这种行为只发生在 USB 驱动器上，但我不明白 gparted 为什么会这样做！
无论如何，从终端卸载分区，我将其卸载，显然它保持卸载状态，我可以告诉 gparted 增大它，它开始增大它，但过了一会儿（20 秒？）它停止说：
/dev/sde 上的分区 5 已写入，但我们无法通知内核此更改，可能是因为该分区正在使用中。因此，旧分区将继续使用。您应该立即重新启动，然后再进行进一步的更改。
保存详细信息，如下所示：

Use -f option if you really want to do that.

libparted messages ( INFO )
Partition(s) 5 on /dev/sde have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use. As a result, the old partition(s) will remain in use. You should reboot now before making further changes.
========================================
您可以看到，当运行 e2image 时，它会停止并抱怨它在 ar/w 挂载的文件系统上运行。但是 - 再次 - 我没有做任何事情来挂载它。
让 gparted 增大我的分区的唯一方法是使用命令不断卸载分区
sudo watch -n 0.1 umount /dev/sde5
这样 gparted 就可以调整分区大小。
我的问题是：
- 实际上是 gparted 挂载了分区吗？？？
- 有没有其他方法可以让 gparted 调整分区大小，而无需使用 watch/umount 命令？
