Trouble with SMB shares

[jimmyhartington]

I have a strange problem with my macs at my workplace. It started from macOS 11.
I can reproduce it on macOS 11, 12 and 13. And on Intel and Apple Silicon.
We work with network shares from Windows 2019 and Synology servers.
It does not happen on the local HD or USB drives.
If I move a file to a folder on a share I can not open it by double clicking, cmd+O or cmd+↓
See this video: https://d.pr/v/wsVGcF

If I rename the file after move, it works just as normal.

I have tried changing /etc/nsmb.conf
It looks like this at the moment:

# /etc/nsmb.conf - macOS 11.3 - 2021-04-29
#------------------------------------------------------------------------------
# SMB configuration for macOS 11.3 <-> Synology

# Lock negotiation to SMB2/3 only

# 2 only SMB 2 enabled
# 1 only SMB 1 enabled

# No SMB1, so we disable NetBIOS
port445=no_netbios


# Turn off notifications
notify_off=yes


# SMB Multichannel behavior
# To disable multichannel support completely uncomment the next line
mc_on=no


# Some Wi-Fi networks advertise faster speeds than the connected wired network.
mc_prefer_wired=yes

This is the output of smbutil statshares -a

Has anyone else seen this behaviour and maybe has a fix?

Unable to duplicate with Synology.

On my Mac nsmb.conf has one line:

cat nsmb.conf
[default]
signing_required=no

smbutil statshares -a

only shows shares from a QNAP NAS although the Synology is mounted and I can copy files to its shares and open them with the options you listed.

Thanks for testing.
Hope somebody else can confirm if they have the same problem.

Hi, Jimmi

i have a similar problem here.. it seems to be a problem derived from the apple client smb.
I have 2 qnap nas in the office, the problem occurs when, in the first nas, I share a remote mounted directory from the second nas and I share it again on the first nas.
windows clients have no problems, they have full sharing privileges, all read, write, erase, execute..
Mac clients can't copy on that share, but they can erase files and browse all directories..
when copy files "error -50" occurs.
i did your same hacks in nsmb.conf but without success,
I think it's the name listed in the mount point, the path in smb.conf of the server (or nas).
mac clients don't like it for some reason..
I tried prevent macOS from reading .DS_Store, but no luck..

Adjust SMB browsing behavior in macOS - Apple Support

The default settings for browsing network folders such as Server Message Block (SMB) shares are ideal for most organizations and users. But you can make adjustments to optimize SMB browsing in enterprise environments.

support.apple.com

with the command in terminal:
defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool TRUE

I have to investigate... more


neverending Sto..
could this help?

Mac Bug Connecting to Non-Apple SMB Shares

Set my folders free! Earlier this year we received a number of reports from users that were unable to delete, move or rename documents on a new SMB file share. Eventually we were able to narrow it …

Unfortunately these problems are not like mine. The articles did not help.
