我在 Ubuntu 16.04.3 LTS 上使用 VeraCrypt 进行了以下设置：
root@ubuntu:/veracrypt# df -h

如何增加 VeraCrypt 容器 (/veracrypt/vc.vol) 的大小？PS 我已经尝试了此处介绍的解决方案扩展 VeraCrypt 容器大小 没有任何运气。这是我尝试扩展音量的方法：
root@ubuntu:~# veracrypt -l
1: /veracrypt/vc.vol /dev/mapper/veracrypt1 /backup
root@ubuntu:~# mount | grep /veracrypt
/dev/mapper/testvg-testlv on /veracrypt type ext4 (rw,relatime,data=ordered)
/dev/mapper/veracrypt1 on /backup type ext4 (rw,relatime,data=ordered)
root@ubuntu:~# resize2fs /dev/mapper/veracrypt1
resize2fs 1.42.13 (17-May-2015)
The filesystem is already 15104 (1k) blocks long. Nothing to do!
我的问题：在上述场景中，容器的增加是否可行？
