Centos7 系统启动docker报错 inotify add watch failed

环境说明：
最近新装的系统启动docker报错，之前没有遇到过。（之前都是系统直接启动，新装机器无报错的情况）
当时排查了很久没找到问题在哪，观察报错信息如下：

提示表文件失败，没有这个文件或者目录。

解决方法：
百度了下这个错误，这个错误的需要注意的是后边提到了mkfs这里，最后找到了是xfsprogs这个版本太低了。
yum   update   xfsprogs

------------------------------------------------

重点在红字加粗部分
百度，BING 国内国际都搜过，无有效帮助信息。
再琢磨 异常日志，注意到 mkfs，遂手动执行了下：
mkfs.xfs -m crc=0,finobt=0 /dev/mapper/docker-253:1-34265854-base
报：
=================================
[root@Docker ~]# mkfs.xfs -m crc=0,finobt=0 /dev/mapper/docker-253:1-34265854-base
unknown option -m finobt=0
Usage: mkfs.xfs
--------------------------------
man mkfs.xfs 了下，的确没有 -m 参数
但...查了下网络资料，发现别人的 man mkfs.xfs 资料有-m参数
问题原因：
===========================================
很明显了：mkfs.xfs版本太低，遂更新：
yum update xfsprogs
重启docker服务，正常！
