Hi guys,
I’m trying to do something quite trivial, but it doesn’t work as I expect and I really don’t have a clue why is that.
In order to work on a clean system I tried all of these tests with TrueNAS appliance running on VirtualBox VM.
Here is my pool:
root@truenas:~# zfs list | grep mnt
Tank 1.23G 15.7G 104K /mnt/Tank
Tank/Share 96K 15.7G 96K /mnt/Tank/Share
boot-pool/ROOT/24.04.0/mnt 96K 25.3G 96K /mnt
root@truenas:~#
In order to keep the things really simple and don’t mess with ACLs I decided to create standard (general) type of dataset, check this out:
When I click on edit of the SMB share I see “Default Share Parameters”:
On a Unix Permission Editor I see:
If I try to locally create a new file or folder with the mentioned user, all good:
test1@truenas:/mnt/Tank$ cd Share/
test1@truenas:/mnt/Tank/Share$ mkdir Zz
test1@truenas:/mnt/Tank/Share$ touch Zz/Aa
test1@truenas:/mnt/Tank/Share$ ls -la
total 2
drwxrwx--- 3 test1 test1 3 May 8 08:42 .
drwxr-xr-x 5 root root 5 May 8 08:20 ..
drwxr-xr-x 2 test1 test1 3 May 8 08:42 Zz
test1@truenas:/mnt/Tank/Share$ ls -la Zz/
total 2
drwxr-xr-x 2 test1 test1 3 May 8 08:42 .
drwxrwx--- 3 test1 test1 3 May 8 08:42 ..
-rw-r--r-- 1 test1 test1 0 May 8 08:42 Aa
test1@truenas:/mnt/Tank/Share$
But if I try to to the same over Samba I got “Permission denied”
kpucko@elementaryOS:~$ sudo mount -t cifs -o username=test1,password=test1 //192.168.56.107/Share /mnt
[sudo] password for kpucko:
kpucko@elementaryOS:~$ mkdir /mnt/Aa
mkdir: cannot create directory ‘/mnt/Aa’: Permission denied
kpucko@elementaryOS:~$
You would say, did you restarted the Samba service?
And yes, I did it:
root@truenas:~# systemctl restart smbd
root@truenas:~# systemctl status smbd

The result is the same 
Samba4 testparam command looks like expected, except the fact there is nothing about my user test1:
root@truenas:~# testparm

Any ideas are welcomed.
Thanks in advance.
