nsa310 and nsa235-V2 admin doesn't have write access to admin share folders

Its really odd but It's not a train crash if this doesn't get sorted. My main aim was to use it as a backup target and, thanks to you, it is working as such.

OK so I started again with a virgin box and created a single internal volume called Backup volume. I used Konsole in Ubuntu. Installed your repo, installed Entware. Nothing else installed.

Created a user with admin rights called Jason

Using the NAS web interface I created a Share called Jason
Share Owner = Jason
Permission Type = Public

I used a pc with Ubuntu. Used Konsole to Telnet to the NSA325-V2

Ran through the SMB upgrade instructions as before

Again got

~ # /opt/etc/init.d/S09ZyXELSambaReplacement start
Stopping Samba daemons: nmbd smbd.
mv: can't rename '/opt/var/lock/*': No such file or directory
~ # ls -l /i-data/md0/

So as you asked . . .

~ # ls -l /i-data/md0/

Using Dolphin file browser the NAS is not listed under Shared Folders (SMB)

I manually typed in
smb://nasIPaddress

I got this list:
- video
- public
- music
- Jason
- Backup volume
- admin

Note that the "Backup volume" is in the list?
Using Dolphin I was able to go into and created a text file in video, public, photo, and music

Tried to go into Jason and got the error . . .
The file or folder smb://admin@192.168.1.140/Jason does not exist.

Tried to go into admin and got the error . . .
The file or folder smb://admin@192.168.1.140/admin does not exist.

Tried to go into Backup volume
Got login box
Could NOT log in as Jason
I could login as admin
got the list:
- video
- public
- photo
- music
- Jason
- admin

in each of the first 4 shares, I could see the text files I had created

I was now able to go into the Jason and create a test file

I went into the admin share and got the list:
- zyfw
- zy-pkgs
- download

I WAS able to create files and folders in these

I switched to the web interface of the NAS

Using the Shares Browser I was NOT able to create any folders or files in the admin share or the Jason share (access denied)
(I tried it logged on both as admin, and also as Jason using the "Administrator Login" button)

• The Backup volume is actually the RAID volume that I created. That's just the name I chose for it.
• (It was a virgin install and I didn't install Backup Planner on it this time).

So I tried again. Another Virgin install - deleted volume - full Factory reset - created new RAID volume, this time I called it NSA325 for clarity - I did not create any users or shares this time - I checked that no recycle bins were active in any share.

Still the same issue. As for the subdirectory you mentioned. it looks like the subdirectory doesn't exist . . .
/ # ls
bin etc init mnt ram_bin sys var
dev home lib opt root tmp zyxel
e-data i-data linuxrc proc sbin usr
/ # cd i-data
/i-data # ls
0b854565 md0

/i-data # cd 0b854565
/i-data/0b854565 # ls
admin lost+found photo video
aquota.user music public

/i-data/0b854565 # cd ..
/i-data # cd md0
/i-data/0b854565 # ls
admin lost+found photo video
aquota.user music public

I ran
smbstatus . . .
Can't load /opt/etc/samba/smb.conf - run testparm to debug it

It looks like Smb.conf does not exist in the folder . . .
/usr/local/zy-pkgs/opt/etc/samba # ls -l
-rw-r--r-- 1 root root 89 Nov 6 2017 ZyXELSambaReplacement.conf

-rw-r--r-- 1 root root 131072 Jan 4 2018 upcase.dat
-rw-r--r-- 1 root root 65536 Jan 4 2018 valid.dat

Maybe the whole samba replacement thing just doesn't work?

Anyway don't waste any time on it. I was just curious about it and I can use it just as a backup device, (which was the original idea anyway)
