扩展 Ubuntu LV - 添加新 HDD

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% /

fdisk 显示：

所有的空间在哪里？我该如何修复它？

固定的

Filesystem               Size  Used Avail Use% Mounted on
/dev/mapper/ubuntu-root  521G  108G  389G  22% /
udev                     961M  4.0K  961M   1% /dev

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
