Chmod and chown invalidate the files of the mounted partition

Today, I want to change the users and user groups of all files in a directory into ordinary users , use chown command

chown -R guest:guest test/

I found that there was no response after the modification ,ll At first glance, users and user groups are still root
And the file permissions are all 777, namely rwxrwxrwx, Try to use chmod modify

chmod 775 test/

It still doesn't work ！！！

Search online , I found that other friends have similar problems ：
chmod stay NTFS Invalid on partition

linux chmod、chown Orders don't work

chown Change the owner of the directory 、 Strange problem of group failure

To summarize , The same point is that the files are located on the mounted partition ！！！

Preliminary conclusion ：chmod and chown Invalid file for mounted partition

Some big guys have solutions. Please comment or point out in a private letter. Thank you ！
