Single NFS share with multiple datasets

[Constantin.FF]

Hello everyone

I am running the latest TrueNAS Scale (22.02.0.1)

And I am hitting some error or limitation of NFS shares.
Here is my dataset layout:
— pool
—— media -> re, NFS shared
——— Movies -> rwe
——— Photos -> rwe
——— TV-shows -> rwe
——— Music -> rwe

I am using the basic Permissions and for media dataset Other have permission for Read | Execute
and the child datasets have Read | Write | Execute

And the media dataset is NFS shares

What I expect was to be able to mount the media share, with no access to write into it, but to be able to browse the child folders and write to them.

I mounted the media share and I can see the child datasets, also no write access directly to media
but also I dont get write access inside the child folders.

Do I miss something?

I have tested to give Write access to the media dataset, and I was able to write successfully.

NFS is fundamentally per-filesystem. That means per dataset in the ZFS context. You need to share and mount each dataset individually.

I have created only the media dataset with read, execute permissions
and created the child folders with

Code:

mkdir Movies && chmod 777 Movies

It got the expected result, but dont know if there might be some unexpected problems

No - folders can be shared with a single NFS share. No problems to be expected. Only that you cannot snapshot/replicate/etc. your folders individually, since all these ZFS features also work on the dataset level.
