Yes, I'd love this!
A lot of companies want samba for simple file access from windows/mac
clients. I know quite some companies that buy netapp as 'easy smb storage'.
Having ceph do built-in (or bolt-on) samba instead of having to manage
external samba clusters would be nice, and would make it more accessible
to replace above storage.
And the result would be better integration between samba and ceph.
Perhaps in code, but also in documentation and example configs.
I set up my own 2 physical node samba cluster, with gluster to host the
CTDB lock file. (with a third machine, a vm, to act as the third node in
the gluster cluster). According to 45drives, saving the CTDB lock file
in CephFS is a bad idea, and doing some rados-mutex thingy was too
complex for me. And this whole solution feels a bit hackish, although it
works wonders. Having a unified tried and tested solution where everyone
is doing the same thing, sounds great!

Hello Ceph List,
I'd like to formally let the wider community know of some work I've been
involved with for a while now: adding Managed SMB Protocol Support to Ceph.
SMB being the well known network file protocol native to Windows systems and
supported by MacOS (and Linux). The other key word "managed" meaning
integrating with Ceph management tooling - in this particular case cephadm for
orchestration and eventually a new MGR module for managing SMB shares.
The effort is still in it's very early stages. We have a PR adding initial
support for Samba Containers to cephadm [1] and a prototype for an smb MGR
module [2]. We plan on using container images based on the samba-container
project [3] - a team I am already part of. What we're aiming for is a feature
set similar to the current NFS integration in Ceph, but with a focus on
bridging non-Linux/Unix clients to CephFS using a protocol built into those
systems.
A few major features we have planned include:
* Standalone servers (internally defined users/groups)
* Active Directory Domain Member Servers
* Clustered Samba support
* Exporting Samba stats via Prometheus metrics
* A `ceph` cli workflow loosely based on the nfs mgr module
I wanted to share this information in case there's wider community interest in
this effort. I'm happy to take your questions / thoughts / suggestions in this
email thread, via Ceph slack (or IRC), or feel free to attend a Ceph
Orchestration weekly meeting! I try regularly attend and we sometimes discuss
design aspects of the smb effort there. It's on the Ceph Community Calendar.
Thanks!
