samba - Jul 2020 - Multiprotocol File Sharing via NFSv4 and Samba

Hi all,
are there any non-commercial solutions (apart from solutions like Dell EMC, IBM
and NetApp) around that allow to simultaneously access the same file system via
NFSv4 and Samba exports in a (nearly) non-conflicting manner, especially w.r.t.
to NFSv4/Windows ACL incompatibilities?

Best
Sebatian

Hi Kraus,

I know that Gluster can be exported  over NFS-Ganesha (supports v4.X),  Samba
(protocol  1.0  in order  to get 'real' permissions), Apple's stuff
and if you rebuild the source - you can use the built-in gNFS (supports NFS v3
over tcp) all at once.

Yet,  I'm not sure  about the ACLs, so you  should either  test it yourself
or ask on the gluster mailing list.


Deployment  is quite easy for a distributed filesystem, so you can test  it 
even on a single VM.

Best Regards,
Strahil Nikolov

FreeNAS / FreeBSD have native NFSv4 ACLs. They do however lack kernel
oplock support so there are perhaps some caveats in that regard.

I've done it at a commercial scale with locally configured NFS on
Linux clients and Samba for CIFS access on windows clients. It's very
tricky to scale, and to maintain consistent privileges. NFSv4 map
somewhat, but not *perfectly* to CIFS credentials. And lock files
become an adventure, because clients *cannot* be entirely in sync with
a centralized server, the constant monitoring and updating to be in
tight4er and tighter sync themselves cost bandwidth and CPU. So
collaboration working with the same files can require thoughtful
programming to ensure atomic operation. I don't recommend it: I'd
generally recommend picking one protocol or the other and using it
everywhere. It's extraordinarily difficult to predict
incompatibilities someone may run into with ocmmercial software,
written to use lock files with *very* peculiar behavior. And of course
there is the filesystem namespace collission issue. In NFS, README.md"
is a different file from README.MD or readme.md, and resolving this
with CIFS clients o the same workspace can be an adventure.

There are many inexpensive office grade petabyte storage servers which
rely on Samba internally and would probably serve your needs.

I have several Solaris files with ZFS file systems that share directories
out via NFS and Samba.     It has been working pretty well.   Latest
releases of Ubuntu and RedHat Enterprise Linux have added ZFS support.
