SMB/CIFS problems to mount a share under Linux

  • Hello everyone,


    I'm using Openmediavault 5.4, I have upgraded from the scratch from Version 4.

    Under OMV 4 I had not problems to mount my CIFS/SMB stuff under ZorinOS ( Linux )


    ## from fstab ##

    //10.*.*.*/NAS /mnt cifs auto ,uid=1000,gid=1000,username=nas,password=***

    since I use OMV5 it is not working the /mnt folder looking like this


    d????????? ? ? ? ? ? mnt/

    and unmounted

    drwxr-xr-x 2 root root 4096 Jun 24 2019 mnt/


    when I try do a LL on the /mnt I get a error massage that access is not possible (file handle)

    I have tryed do a manual mount, same result like the fstab mount and also no error massages.


    when I do dmesg I get this

    [11818.422848] No dialect specified on mount. Default has changed to a more secure dialect, SMB2.1 or later (e.g. SMB3), from CIFS (SMB1). To use the less secure SMB1 dialect to access old servers which do not support SMB3 (or SMB2.1) specify vers=1.0 on mount.

    [12290.271676] CIFS: Attempting to mount //10.*.*.*/NAS

    [13149.553801] CIFS: Attempting to mount //10.*.*.*/NAS

    [13423.797909] CIFS: Attempting to mount //10.*.*.*/NAS

    [13705.012771] CIFS: Attempting to mount //10.*.*.*/NAS


    I already tryed to use the cifs vers=1.0 to 3.0 instad cifs auto but that not helped too.


    And now the funny part.
    Under Windows 10 I have no problems to access the SMB share, and under ZorinOS (this is Ubuntu 18) also NO problem when I use Nautilus (it is like the Explorer under Windows ) to browse the network I can see the share and I can access it.


    I have absolute no clue, since 2 days I trying to solve the problem no success.

    Right now I use NFS, and with NFS I can mount my stuff without problems.
    Slowly I think I will downgrade back to OMV 4.


    I hope someone have a idea, what else I can try.
