Samba locking for edit docx, xlsx, pptx

I have a CentOS Linux 5.6 with Samba version 3.0.33-3.29.el5_5.1 The system is fully working except newer office files are all locked for editing. If I click the notify button it will let me open the document for editing after approximately 10 seconds. As soon as I save it as a previous version of office it opens and it editable by all users. The locking happens for all users.
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# For a step to step guide on installing, configuring and using samba,
# read the Samba-HOWTO-Collection. This may be obtained from:
#  http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
#
# Many working examples of smb.conf files can be found in the
# Samba-Guide which is generated daily and can be downloaded from:
#  http://www.samba.org/samba/docs/Samba-Guide.pdf
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.
#
#---------------
# SELINUX NOTES:
#
# If you want to use the useradd/groupadd family of binaries please run:
# setsebool -P samba_domain_controller on
#
# If you want to share home directories via samba please run:
# setsebool -P samba_enable_home_dirs on
#
# If you create a new directory you want to share you should mark it as
# "samba-share_t" so that selinux will let you write into it.
# Make sure not to do that on system directories as they may already have
# been marked with othe SELinux labels.
#
# Use ls -ldZ /path to see which context a directory has
#
# Set labels only on directories you created!
# To set a label use the following: chcon -t samba_share_t /path
#
# If you need to share a system created directory you can use one of the
# following (read-only/read-write):
# setsebool -P samba_export_all_ro on
# or
# setsebool -P samba_export_all_rw on
#
# If you want to run scripts (preexec/root prexec/print command/...) please
# put them into the /var/lib/samba/scripts directory so that smbd will be
# allowed to run them.
# Make sure you COPY them and not MOVE them so that the right SELinux context
# is applied, to check all is ok use restorecon -R -v /var/lib/samba/scripts

#
# set local master to no if you don't want Samba to become a master
# browser on your network. Otherwise the normal election rules apply

#----------------------------- Name Resolution -------------------------------
# Windows Internet Name Serving Support Section:
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
#
# - WINS Support: Tells the NMBD component of Samba to enable it's WINS Server
#
# - WINS Server: Tells the NMBD components of Samba to be a WINS Client
#
# - WINS Proxy: Tells Samba to answer name resolution queries on
#   behalf of a non WINS capable client, for this to work there must be
#   at least one	WINS Server on the network. The default is NO.
#
# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
# via DNS nslookups.

# --------------------------- Printing Options -----------------------------

# --------------------------- Filesystem Options ---------------------------
#
# The following options can be uncommented if the filesystem supports
# Extended Attributes and they are enabled (usually by the mount option
# user_xattr). Thess options will let the admin store the DOS attributes
# in an EA and make samba not mess with the permission bits.

Hello nlhess2003, through which share are you experiencing this issue? Did you perhaps only test with a .DOCX file because here is a small typo:

veto oplock files = /*.xls/*.XLS/*.xlsx/*.XLSX/*.doc/*.DOC/*.docx/*.DOXX/*.xlt/*.XLT/*.dbf/*.DBF/*.ntx/*.NTX/

You mean: DOCX instead of DOXX right?
0
 
nlhess2003Author Commented:
The share we are working on right now is corpfiles. Unfortunately we have mainly been working with xlsx files. I have updated the .DOCX and those still aren't working either.

The new generation of project management tools

With monday.com’s project management tool, you can see what everyone on your team is working in a single glance. Its intuitive dashboards are customizable, so you can create systems that work for you.

 
Gerwin Jansen, EE MVETopic Advisor Commented:
Ok, was worth a try. Could you add ~$*/ to your veto oplock files, like this:

veto oplock files = /*.xls/*.XLS/*.xlsx/*.XLSX/*.doc/*.DOC/*.docx/*.DOCX/*.xlt/*.XLT/*.dbf/*.DBF/*.ntx/*.NTX/~$*/

This is because when opening an xlsx file, Excel is creating a ~$<filename> as well - this does not happen when you open an xls file.

Office version?
Format converter locks primary file completely and edits a copy.

nlhess2003Author Commented:
I have tested with Office 2003, 2007, and 2010. All have the same issue. I am able to click Notify when file is unlocked and about 10 seconds later it lets me edit the file.

Disable offline files on client side. If it solves problem you can disable it per-share on a server

How do I disable offline files on the client side?

Gerwin Jansen, EE MVETopic Advisor Commented:
>> client side

What clients (OS) do you have?
0
 
Gerwin Jansen, EE MVETopic Advisor Commented:
In Windows 7:

- Open the Control Panel (All Items view), and click on the Sync Center icon
- In the left pane, click on the Manage offline files link
- Click on the Disable offline files button (If prompted by UAC, then click on Yes)
- Restart computer (as prompted) - save any files if needed

Offline files are already disabled on the computer I am using.

Next try - disable client antivirus for some share, maybe it is at fault (generating document previews) and you can shop for other and disable all other tweaks mentioned around.

Gerwin Jansen, EE MVETopic Advisor Commented:
Use a file monitoring utility on your client side to see what files are opened on the SMB share during the first 10s. Process Monitor or Process Explorer from Sysinternals (MS) will work just fine. Set filters on 'excel.exe' or 'winword.exe' depending on what you're testing.
