安装 Ubuntu 16.04.1 后，我在硬盘的可用空间上创建了新分区。无法挂载
/dev/mapper/MYVGNAME--vg-images
在启动时。有人能帮助我吗？
此 id“df -h”输出：
Filesystem Size Used Avail Use% Mounted on
udev 474M 0 474M 0% /dev
tmpfs 99M 3.2M 96M 4% /run

这是“pvdisplay”输出：

这是“nano /etc/fstab”的输出：
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

# <file system> <mount point> <type> <options> <dump> <pass>

# /boot was on /dev/sda1 during installation

/dev/mapper/MYVGNAME--vg-swap_1 none swap sw 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0
想要这个：
Filesystem Size Used Avail Use% Mounted on
udev 474M 0 474M 0% /dev
tmpfs 99M 3.2M 96M 4% /run
/dev/mapper/MYVGNAME--vg-root 24G 1.6G 21G 8% /
tmpfs 492M 0 492M 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock

tmpfs 99M 0 99M 0% /run/user/1000
/dev/mapper/MYVGNAME--vg-images 100G 60M 95G 1% /images

您需要在 /etc/fstab 文件中添加条目
sudo nano /etc/fstab
/dev/mapper/MYVGNAME--vg-root / ext4 默认值 0 1
/dev/mapper/MYVGNAME--vg-images /images ext4 默认值 0 1
