Zyxel NAS542 - copied files from old NAS are inaccessible (open from NAS share)

adrian3k

Hi.
I have a Zyxel NAS 542 (4 bay) with 2 HDD, I've created a share folder, created a user with all access and copied old NAS files (320gb, over 400000 files) to this new share. Now I have a problem with opening files directly from NAS shared folder, when copied to local drive - all works fine. I've checked the permissions on files and folders (ssh, ls -alh) and it was okay (USER everyone rwx), created a NEW file on the same folder and checked again (ssh, ls -alh). The copied files were unable to open (cad files, project files, archives), the new file was fine.
Anyone have an idea what can be wrong?

Shares are done by drive mapping with user/password - I even used "chown USER -R *" on the copied files, still the problem exists...

Ah sorry, missed that post. Well, after looking at the files, the most probable difference I can find is oplocks. That's a Windows way to lock files, to prevent multiple edit sessions at a time. I can imagine some editors just refuse to work if they can't get exclusive access

In old file we have

<div>[global]</div><div><br></div><div>oplocks = yes</div>

in new file it's

<div>[global]</div><div><br></div><div><div>kernel oplocks = no</div><div><br></div>level2 oplocks = no</div>

(I'm very happy that smb.conf always have simple, not confusing options)

So try to edit the latter to 'yes', and restart samba.

<div>/etc/init.d/samba.sh restart<br></div>

What happens if you copy a file to local, rename it and copy it back? Is it accessible? And if yes, what is the difference in

ls -la old_file new_file

adrian3k

-rwxrwxrwx    1 USER      everyone  538.5K Feb  6  2019 File.dwg

-rwxrwxrwx    1 USER      everyone  538.5K Feb  6  2019 File test.dwg

File is still not accessible directly form NAS...

btw. using Total Commander to copy files (copy NTFS permissions is UNCHECKED)

Was you able to access the file when it was on the old share? Was that on the same NAS, and does it still exist? If yes, have a look in /etc/samba/smb.conf to see what the difference is between the shares.

Old NAS was on FreeNAS (old version like 9.1 or smth).
The old server is not formatted yet, but I wasn't the person that configured it.
Will try to take a look into the file. On Zyxel i should ssh to the server and change values there and it would work or do I have to edit it thru webpanel?

Unfortunately editing the smb.conf isn't straight forward. The file is dynamically generated by the backend, and not all settings have a counterpart in the webinterface.

Yet if you manage to find the difference, the samba manual can tell if it makes sense, and it is possible to edit smb.conf and restart samba until the next reboot or webinterface action.

Depending on the exact difference it might be possible to inject it @boot time.

Mijzelf I have managed to get to old server - there is no /etc/samba/smb.conf file
It was configured on CIFS (i think, not sure)
options: Local master was checked, account for guest: nobody
dont see any other things that should matter...
