我已经在我的个人电脑上安装了新的硬盘，并按照本指南扩展了逻辑卷，但几乎没有获得任何空间？

我开始是这样的
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 250GB 硬盘并按照上述指南操作，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

none 100M 0 100M 0% /run/user
/dev/sda1 228M 53M 164M 25% /boot
fdisk 显示：

所有的空间在哪里？我该如何修复它？

缺少了什么...找到 免费 PE / 大小 57574 / 224.90 GiB
然后运行
sudo lvresize -l +57574 ubuntu/root
然后
sudo resize2fs /dev/ubuntu/root
