如何增加 /home 中的空间，Ubuntu 14.04

Question

我当前的磁盘使用情况如下：

$:df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sdd2       1.4T   13G  1.3T   1% /
none            4.0K     0  4.0K   0% /sys/fs/cgroup
udev             30G  4.0K   30G   1% /dev
tmpfs           5.9G  1.9M  5.9G   1% /run
none            5.0M     0  5.0M   0% /run/lock
none             30G  152K   30G   1% /run/shm
none            100M   44K  100M   1% /run/user
/dev/sdd4       184G  159G   16G  92% /home

而且我的 /home 目录几乎已经满了，有什么方法可以利用 '/' 下的空间来增加我的 '/home' 目录吗？

谢谢

编辑：根据要求，我发布了 sudo parted -l 的输出：

虽然您可以调整分区大小，但这很繁琐（最终的错误可能会造成灾难性的后果），但您可以在主目录中创建实际存在的文件夹/（通过链接或绑定挂载）：

# First make directory in `/` to hold your data:
sudo mkdir -p /var/home-stuff
sudo chown $USER:$USER /var/home-stuff

然后创建一个链接：

ln -s /var/home-stuff ~/folder-in-root

或者将其绑定到你家里的文件夹：

mkdir -p ~/folder-in-root
sudo mount -o bind /var/home-stuff ~/folder-in-root
sudo chown $USER:$USER ~/folder-in-root

^{_{（您可以通过向 添加条目来使此绑定永久生效/etc/fstab。）}}

现在放入的任何东西~/folder-in-root实际上都会占据空间/。
