我的主分区安装在/是14GB。 相同的驱动器具有额外的47 GB的免费未分区空间。 如何将空间添加到根分区?
非常感谢你的帮助。

自己找到答案。花了一会儿。解决方案如下:
创建分区:
[$]# fdisk /dev/sda
Command (m for help): n
Partition type:
p primary (2 primary, 0 extended, 2 free)
e extended
Select (default p): p
Partition number (3,4, default 3): 3
First sector (33554432-125829119, default 33554432):
Using default value 33554432
Last sector, +sectors or +size{K,M,G} (33554432-125829119, default 125829119):
Using default value 125829119
Partition 3 of type Linux and of size 44 GiB is set
Command (m for help): w
The partition table has been altered!
初始化分区:
[$]# pvcreate /dev/sda3
扩展音量:
[$]# vgextend centos /dev/sda3
扩展分区:
[$]# lvextend /dev/centos/root /dev/sda3
调整分区大小:
[$]# xfs_growfs /dev/centos/root
