[root@localhost ~]# resize2fs /dev/mapper/centos-root

resize2fs: Bad magic number in super-block while trying to open /dev/mapper/centos-root错误

需要修改命令使用xfs_growfs /dev/mapper/centos-root
如下

[root@localhost ~]# xfs_growfs /dev/mapper/centos-root
meta-data=/dev/mapper/centos-root isize=512    agcount=4, agsize=2509824 blks
