Gluster users - Aug 2015 - Need help making a decision choosing MS DFS or Gluster+SAMBA+CTDB

If you're looking at a Gluster+Samba setup of any description for
people extensively using Microsoft Office tools (either Windows or Mac
clients), I *strongly* suggested exhaustive testing of Microsoft Word
and Excel.

I've yet to find a way to make these work 100% on Gluster.  Strange
client-side locking behaviour with these tools often make documents
completely unusable when hosted off Gluster.   We host our large
production files (VFX industry) off Gluster, however have a separate
Windows Server VM purely for administration to host their legacy
Microsoft Office documents (we've since migrated largely to Google
Apps + Google Drive for that stuff, but the legacy requirement remains
for a handful of users).

An example of a working share on samba4:

You can choose to work with vfs objects= glusterfs 
Glusterfs:volume=yourvolume
Glusterfs:volfile.server=Your.server
Form e it turned out to be too buggy.


I just used instead the path=/path/toyour/mountedgluster

You will need this:
posix locking =NO
kernel share modes = No

 [edv]
comment=edv s4master verzeichnis auf gluster node1
vfs objects= recycle
##vfs objects= recycle, glusterfs
recycle:repository= /%P/Papierkorb
##glusterfs:volume= sambacluster
##glusterfs:volfile_server = XXX.XXXX.XXXX
recycle:exclude = *.tmp,*.temp,*.log,*.ldb,*.TMP,?~$*,~$*,Thumbs.db
recycle:keeptree = Yes
recycle:exclude_dir = .Papierkorb,Papierkorb,tmp,temp,profile,.profile
recycle:touch_mtime = yes
recycle:versions = Yes
recycle:minsize = 1
msdfs root=yes
path=/mnt/glusterfs/ads/wingroup/edv
read only=no
posix locking =NO
kernel share modes = No
access based share enum=yes
hide unreadable=yes
hide unwriteable files=yes
veto files = Thumbs.db
delete veto files = yes
