Samba shares VS Windows & MacOS

Hello there,

I would like to share with you the solution for some issues we had:

  1. Windows: related to owners/permissions - when creating 1 folder 4 copies (called new folder) were created. Fixed cleaning up all permissions on the directories and on the root and setting the right owners. (some chmod/chown needed server side was probably a leftover of previous migration of data)

  2. MacOS (latest) + Adobe: locks not relased while working on the nas, leading to undeleatable files, errors while saving etc. Seems related to the preview but they cannot disable it. It’s mitigated mounting the samba share with cifs:// instead of smb://.

  3. MacOS (latest) + Office365: HORRIBLE BUG , leading to data loss. Again when preview is activated multiple tempfiles are created and not deleted correctly, then the original file is deleted :bomb:

Fixed with this script to run MacOS side (on the client):

 #!/bin/bash

# Casper PlistBuddy script to disable icon previews and the preview pane for enhanced 
# SMB share compatibility.  Should work with 10.9 through 10.11 (and beyond?)

# This script elaborates on some brilliant work from gumptiontech at the following link:
# http://gumptiontech.co.uk/2015/06/17/disable-mac-10-9-finder-thumbnail-preview-by-command/
#
# I've modified it to run as root and act on the currently logged in user.  Also added 
# additional lines to shut off the preview column in the column finder view, and to 
# disable .DS_Store creation on SMB shares.
#
# This should be run at user login, or by any other means while the target user is logged in.
