我已经安装了一个新的硬盘驱动器到我的电脑，并遵循本指南来扩展逻辑卷，但我几乎没有获得任何空间？

我是这样开始的
Filesystem Size Used Avail Use% Mounted on /dev/mapper/ubuntu-root 292G 107G 171G 39% / udev 961M 4.0K 961M 1% /dev tmpfs 388M 492K 388M 1% /run none 5.0M 0 5.0M 0% /run/lock none 970M 0 970M 0% /run/shm none 100M 0 100M 0% /run/user /dev/sda1 228M 53M 164M 25% /boot 我安装了一个250GB的硬盘，并按照上述指南，现在我有：
Filesystem Size Used Avail Use% Mounted on /dev/mapper/ubuntu-root 300G 107G 178G 38% / udev 961M 4.0K 961M 1% /dev tmpfs 388M 492K 388M 1% /run none 5.0M 0 5.0M 0% /run/lock none 970M 0 970M 0% /run/shm none 100M 0 100M 0% /run/user /dev/sda1 228M 53M 164M 25% /boot
fdisk显示了这个：

所有的空间在哪里，我如何解决它？

什么是失踪…查找免费PE /大小57574 / 224.90 GiB
并运行
sudo lvresize -l +57574 ubuntu/root
然后
sudo resize2fs /dev/ubuntu/root
