NFS is sharing even if disabled

[Pheggas]

Hello. So i set up users, datasets, and now i'm setting up SMB and NFS share. With SMB isn't any problem. But the whole NFS system makes me crazy. I started by heading to Sharing -> NFS -> Add -> selecting path and checking "All dirs" so that all subdirs will be accessible. After creating this NFS share i head into Services and turn on NFS server. Now i wanted to connect to NFS share inside my Windows Server VM through the Veeam's Backup Repository but i can't. It's throwing error "No write access to destination" which is weird as i didn't check "Read Only" in NFS share.

I checked the accessibility by mounting that path with NFS via Ubuntu Server i have (used sudo mount -t nfs 192.168.1.72:/mnt/path/to/folder /mnt/NAS). It worked but i noticed i wrote the folder above selected folder in NFS share inside TrueNAS. I thought how it is possible to access the folder above the selected one in TrueNAS? So i disabled that NFS share but keep NFS server turned on. Guess what, the mounted path still worked and was still accessible. This means i don't need any NFS shares to basically share my whole dataset (and possibly other datasets too)?

Am i missing something or is this a really big security flaw?

TL;DR: Noticed that whole dataset is still accessible after disabling NFS share but keeping NFS server turned on inside TrueNAS.

-alldirs doesn't make subdirs "accessible". For NFSv3 it allows subdirs to be mount points - it's similar to creating a share for every single subdirectory.

(It's also implied/unnecessary with NFSv4. Subdirs can always be mounted with NFSv4.)

Do those pools have the sharenfs ZFS property set?

From the shell:
cat /etc/zfs/exports
zfs get sharenfs pool/dataset

I'm really sorry but i already did some tinkering during the day and now i'm fully switched to only SMB (yes, i had SMB and NFS shares to the same dataset which is wrong and i already realised it). After all, i still don't understand why it was accessible. Thank you for responding to my post anyway. I really appreciate it!

If SMB works for you I think it's great to use a single protocol!
