我的磁盘分区如下：
df -h给出：
Filesystem Size Used Avail Use% Mounted on
/dev/md1 19G 18G 0 100% /
none 4,0K 0 4,0K 0% /sys/fs/cgroup
udev 16G 4,0K 16G 1% /dev

/dev/md0 268M 36M 214M 15% /boot
/dev/md2 1,7T 68M 1,7T 1% /data
并fdisk -l给出

我正在寻找将 100GB 移动到已充分利用的最简单的/dev/md2方法 /dev/md1。
答案1
最简单的方法是使用 gparted。Fdisk 不是首选工具，parted（或 gparted）更好，因为它们支持较新的 gpt/efi 磁盘布局。
在终端运行中
sudo apt-get install gparted
