Can unfortunately not find the cause.
Any help is appreciated.

it is irrelevant if "SMB2" or "SMB3" protocol is defined.

Same with the options

Code: Select all

oplocks = no
strict locking = no

Doesn´t help either

Code: Select all

samba restart

Only this helps:

Code: Select all

samba stop
samba start

or a reboot

similar problems have been solved.
howto for 9.3:
viewtopic.php?f=21&t=11575

10.3 version, couldn't use for databases (very slow database work)
viewtopic.php?f=21&t=11621

but 10 version with virtualbox, you can install on VM (opennas , nas4free9, ms windows ) for databases.

@onega23
thx but doesn´t works for me.

It seems it´s a problem in Samba see https://wiki.samba.org/index.php/Samba_ ... ed/changed Bug #10564.

Update to N4F v. 10.3.0.3 (3105) doesn't help.

got a feedback from a samba developer:

append option

Code: Select all

posix locking = no

in /var/etc/smb4.conf or directly via gui in services + CIFS/SMB + Auxiliary parameters.

Works perfect for smb2 + smb3 for me
