Access denied for my shared folder

Hi, I've just installed OMV on my raspberry pi 3. I've set up file system, shared folder and enabled SMB service. Although I have followed the steps shown in this tutorial: https://youtu.be/gyMpI8csWis. I get "Access denied" error every time i want to write something on my drive. Maybe something's wrong with my mount folder permission settings?

pi@raspberrypi:~ $ ls -la /srv/
total 52
drwxr-xr-x  6 root root     4096 Aug 27 13:20 .
drwxr-xr-x 19 root root     4096 Aug 25 16:45 ..

Thanks for help macom

I've set up my OMV again according to New User Guide. Everything runs fine until I try to modify file (while using vim i get "Write error (file system full?)"), or move directory to my shared folder (in this case the copy of directory appears in my shared folder, bu it's empty)

I'm using arch linux with dolphin as file manager on my client device. I use SMB protocol for my NAS.

I've set up NFS share and everythings working great!

Samba works fine on my Windows machine too.

Thank's for help
