I have an issue with trying to move files between data shares between two pools. I’m trying to use filebrowser to move files in between them but get a 403 error.
You might want to look into ACL modes. When a docker container / app wants to chmod something in an dataset generally it won’t work without being set to passthrough. You can find the setting under the “advanced options” when editing a dataset.
Had that same “not permitted” error when I tried to use Filebrowser on a 3 year old dataset/SMB share even though I changed its permissions by adding apps as a user with full control recursively. I could acess the old SMB share but not acess/copy its files or sub folders. Eventually, I solved it by making a new SMB share/dataset with all the correct permissions, apps as a user, and copied the old data into the new share.
