我正在尝试使用 HDD 上的全部可用空间（1TB，从 500GB HDD 迁移）。我的分区已加密 (LUKS)。
我尝试基于这，但是lvresize似乎没有将我的分区扩展到 ~ 1TB：
sudo lvresize -l+100%FREE /dev/mapper/vg_oc2462701832-lv_root
Size of logical volume vg_oc2462701832/lv_root unchanged from 449.47 GiB (115065 extents).
Logical volume vg_oc2462701832/lv_root successfully resized.
我的设置：
sudo fdisk -l /dev/sda
Disk /dev/sda: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors

我也尝试过使用blivet-gui 调整 LVM 的大小（来自 Fedora 26 live CD），如下所示：
导致以下操作：
