mv: failed to preserve ownership for ‘***’: Permission denied

在Linux下经常进行多用户下的拷贝，移动等操作。
在向/mnt/nfs/目录下拷贝数据时出现如下提示：
mv: failed to preserve ownership for ‘/mnt/nfs/COCO/train2014/COCO_train2014_000000021504.jpg’: Permission denied
mv: failed to preserve ownership for ‘/mnt/nfs/COCO/train2014/COCO_train2014_000000321849.jpg’: Permission denied
mv: failed to preserve ownership for ‘/mnt/nfs/COCO/train2014/COCO_train2014_000000219410.jpg’: Permission denied
mv: failed to preserve ownership for ‘/mnt/nfs/COCO/train2014/COCO_train2014_000000309598.jpg’: Permission denied

本来已经移动失败了，其实没有，是如下原因：

type vfat

There’s your problem. vfat knows nothing about Linux permissions. It’s not an issue of USB mounts, but of file-systems used.

Oh: and to answer your question - no, it’s not a problem.
这是因为目的地址是vfat文件系统，该系统不知道Linux下的权限问题，所以无法保存权限，这不是问题。
可以正常移动。
