Apps group give everyone read only access , how to give other group write / modify access

Truenas new using files and setting up from a old NAS .

Running qbittorrent and jellyfin on a SMB shared media dataset /mnt/my_dataset/Media/media.

most of the files in the media folder are set to full access to every group and user , some made by copying over SMB and some with qbittorrent on a other NAS.

Now anything which is made by a app only gives full control it it’s self , I can’t delete anything in the totally open share, the app setting won’t allow me to set a admin user/group , is there any way to set apps more open ?

Rather than using the everyone@ entry to define permissions (assuming v4 ACLs) you can grant full control to the specific groups that everyone is a member of (builtin_users for example) as well as the apps group. Apply recursively, and then even if app decides to chmod, it won’t impact ACL. If the app is copying from one place to another, then see if internally it has configuration option to not preserve permissions from source (this will have the copied files auto-inherit permissions from parent directory – which you already defined as open).

I made a test dataset for I wasn’t that brave to do it to my 7TB media dataset .

I tried lots of things and just made it worse , after a start again making a new test dataset I found in permissions edit > user preset > and used NFSv4 open .

Now file / directory made , copied , transferred is open to read , write , modify to user , group , anyone .

I didn’t know why my dataset permissions look to be a mix of unix , NFSv4 and POSIX .
