samba - Feb 2011 - CentOs 5.5 Glusterfs 3.1.0 Samba 3.5 MSOffice Files

Dear all,

I have set up a two node workin gluster with glusterfs3.1 and Samba-Sernet
3.5.
Everything is working great except MSOffice files (Word/Excell). On the
gluster-vol they have the strange behavior
That they rest read only, write protected. Every other type of files can be
manged without problem, openoffice files too.
So when I save a word file on the vol and try to change it it is write
protected. When I open the word file with openoffice I can
change it without any problem?
Is there a bug in samba concerning glusterd?
My share config:

[test]
        path = /mnt/glusterfs/windows/test
        write list = "Domain Users", "Domain Admins"
        force group = "Domain Users"
        read only = No
        create mask = 02770
        force create mode = 02770
        profile acls = Yes
        veto oplock files
/*.mdb/*.MDB/*.dbf/*.DBF/*.doc/*.docx/*.xls/*.xlsx/*.tmp/*.TMP/?~$*/~$*/*.ex
e/*.com
        oplocks = No
        level2 oplocks = No

I did with a simpler share, but it is the same bahaviour.
Telling me: another user.... open read only.....
I think Fuse/Glusterfs cannot manage msoffice files written from msword or
msexcell.
If I change or create doc file with openoffice everything is working on the
fly.

As far as i know, the newer versions of MSO creates tmp-files during the 
save operation. So try to change or uncomment the "veto oplock files" 
and/or the "force create mode" directive.

Maybe you start with a simpler share definition, like this:
[test]
        path = /mnt/glusterfs/windows/test
        write list = "Domain Users", "Domain Admins"
        force group = "Domain Users"
        read only = No

Remember that office files are not normal. When you save in office the
application creates a temporary file then deletes the previous file
then renames the temporary file with the same filename as the the
original. When that happens the windows filesystem automatically
applies the permissions of the recently deleted file to the file that
was just renamed to the same name. *nix filesystems do not have that
strange behavior. I believe on my work network I needed to use a force
create mode to fix this issue with some 3.0.X version of samba and I
have not changed it in years..

John

But even with the force group or force create mode it is still not possible
to do it on a glusterd vol.
I think I will skip glusterd and return to gfs2 and drbd.

Posix locking is yes so I will point it to no!?

Have you taken a look at the smb.conf "posix locking"
option? The posix read lock is not directly related to
oplocks.

If you want to avoid the posix lock calls, yes. I am not
certain however that this will be the final fix for the
problem. I have not seen the full logfiles yet, you only
have small snippets available.

I did it thank you, Volker:

This is my share definition (especially for msoffice files) working on a
gluster-vol.So you can replicate your data to as many server you want:

  [test]
        path=/mnt/glusterfs/windows/test
        readonly=no
        profile acls = YES
        oplocks=NO <--- This is the most important setting
         posix locking = NO
        level2 oplocks=NO
        #oplocks auf dem share fuer folgende file-types ausschalten
        veto oplock files
/*.mdb/*.MDB/*.dbf/*.DBF/*.doc/*.docx/*.xls/*.xlsx/*.tmp/*.TMP/?~$*/~$*/*.ex
e/*.com
        write list=@"Domain Users" @"Domain Admins"
        create mask = 2770
        force create mode=2770
        force group= "Domain Users"
