Linux扩展根分区报错：xfs_growfs ：/dev/mapper/center-root is not a mounted XFS filesystem
扩展根分区报错，xfs_growfs 提示is not a mounted XFS filesystem
执行xfs_growfs /dev/mapper/center-root
结果报错xfs_growfs ：/dev/mapper/center-root is not a mounted XFS filesystem
实际上xfs_growfs执行对象应该是挂载点，而不是设备名。
挂载点通过命令df -h查询
我的/dev/mapper/center-root 挂载点 /
同步文件系统命令：xfs_growfs /
