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=    agcount=, agsize= blks
         =                       sectsz=   attr=, projid32bit=
