[Gluster-users] Need help making a decision choosing MS DFS or Gluster+SAMBA+CTDB

[Dan Mons]

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).
