CentOS 7：热增加启动分区，然后添加逻辑卷？

在 CentOS 7 服务器上，我的/boot分区空间几乎用完了，我需要增加其空间。

接下来是逻辑卷，如下所示：

df-h

# df -h
Filesystem                  Size  Used Avail Use% Mounted on
/dev/mapper/vg_sys-lv_root   70G  8.1G   59G  13% /

tmpfs                       3.9G     0  3.9G   0% /sys/fs/cgroup
/dev/sda1                   190M  147M   30M  84% /boot
tmpfs                       783M     0  783M   0% /run/user/0

至于我能理解的，逻辑卷是泊坞窗安装（现在未运行）。
