I just migrate from Xenpology to Unraid, I move my photo libary to Unraid. I create a share in disk2 call DCphoto, there are many folders and a lot of photo (files) inside the folders. I want to grant permission to all files by give the ownership of DCphoto to ROOT and set permission to everyone with R/W. However, when checking the permission in files under the folders, there is no permission at all. How can I give the permission to all folders and files, ther are more than hundred of folders and thousands of photos.

You control access in Unraid at the share level for access over the network as described here in the online documentation accessible via the ‘Manual’ link at the bottom of the GUI or the DOCS link at the top of each forum page.

 

 From your description you probably want the Private level unless you want to control even those who have read access in which case the Secure option becomes relevant.  Note that the ‘root’ user does not have access via a network share.
