SMB connection issue after June update

Help and Support Vero 4K / Vero 4K +

And you’ve had the issue also with 6.2.3-25426?

48

Hi @JimKnopf,
It’s a DS218j with DSM 6.2.2-24922 Update 4.

I’m ready to upgrade to DSM 6.2.3-25426 but didn’t want to do concurrent upgrades while debugging.

49

Could you tell us later after upgrade to DSM 6.2.3-25426 whether you can reproduce this issue with the original settings (max. smbv2 on both devices)? Thx in advance.

50

:man_facepalming: forgot to mention that part… Yes.

51

Hi,
the issue is still present with DSM 6.2.3-25426 and SMBv2.
All ok with SMBv3

52

I’m having the same issue with a Synology NAS and Vero 4K, using SMB v2. Since I’m not in a hurry I will wait for the fix.

Or should one generally have SMB3 enabled? I wonder why it’s not by default?

53

It’s surely recommended for performance and security.

54

I can confirm that enabling SMB v3 on Synology NAS fixed the issue.

55

I, too, am experiencing this problem… but my media is on an older NAS which can’t do SMB3; I’m stuck with SMB2. I tried an NFS share, which allows the media to play but without any transport controls… so I’d be really grateful for the SMB2 fix.

56

For our understanding, is this also a Synology NAS or a different brand?

Can you explain what you mean without transport control?

If you don’t want to wait for the fix you also could switch to kernel based mounts (eg autofs).

57

I will produce a new build to address this tomorrow.

Thanks for your reply. :slightly_smiling_face:

Correct, not a Synology box. It’s an old D-Link DNS323 on Alt-F firmware. Not enough ROM to update Samba as far as the developer says. It’s old and slow but it works for me as a media server.

No transport controls = no play/pause/stop etc functionality in Kodi - I only get this behaviour when playing a media file on an NFS share. SMB shares are usually fine. Very weird.

Either way… If a fix is coming soon it’s no big deal for me to wait a bit. Frankly being forced away from the TV is something I really need right now… :smiley:

Thank you all!

Thats really strange and should not be related to the switch from SMB to NFS.

I’ve pushed a solution that should work for everyone, but needs some testing.

Can someone please adjust their NAS settings back to how they were and try the following update?

Under Settings → Services → SMB Client, there is a new setting: “Fix issues MTU issues with SMBv2 NAS devices”. This is enabled by default and should resolve the issues you have been experiencing. If you uncheck the box, the issues should occur again.

I’d appreciate it if you could test this and provide feedback before we potentially release this as an update to other users. To test this update:

  1. Login via the command line
  2. Edit the file /etc/apt/sources.list
  3. Add the following line: deb http://apt.osmc.tv stretch-devel main
  4. Run the following commands to update: sudo apt-get update && sudo apt-get dist-upgrade && reboot
  5. Your system should have have received the update.

Please see if the issue is resolved.

I also recommend you edit /etc/apt/sources.list again and remove the line that you added after updating. This will return you to the normal update channel.

Hi,
The fix works here:

  • with “Fix MTU issues” enabled and SMB2 on NAS: OK
  • with “Fix MTU issues” disabled and SMB2 on NAS: Error
  • with “Fix MTU issues” disabled and “SMB2 with large MTU” on NAS: OK
  • with SMBv3: OK

Thanks.

Confirm success on the D-Link DNS323 with the published fix.

Fix on = OK
Fix off = original issues resurface.

No undesirable behaviour discovered.

Thank you!

I had the same problem with June update and the SMB MTU fix works for me as well

I had the same problem, and it’s fixed with that solution. Thanks.

72

Has this been merged into the June update yet?

Yes.
