Update: Event cancelled.

SerNet GmbH will be at this year's Chemnitzer Linux-Tage (CLT 2020) on March 14th and 15th. SerNet's Samba team will be presenting the open source project Samba and the in-house software packages SAMBA+ in the "Linux Live" exhibitor area (booth no. 33, link to hall plan).

Among others, Samba release manager Karolin Seeger, SerNet co-founder Volker Lendecke and Björn Jacke will be present in Chemnitz. All of them are not only long-standing colleagues of SerNet but also of the international Samba team and are looking forward to questions, discussions and suggestions.

Volker Lendecke will give a talk on "Implementing SMB Semantics in a Linux Cluster" at Vault '20, the Linux Storage and Filesystems Conference on February 24–25, 2020, in Santa Clara, CA/USA. Lendecke is SerNet co-founder and long-time Samba Team member.

The talk is scheduled onTuesday, 2:30 pm–3:00 pm. From the abstract:

"To implement the SMB protocol, Samba has to implement semantics that are not covered by the Linux kernel API. The protocol element to mention here are the concept of share modes and leases, similar to NFSv4 share reservations and delegations. To implement those, Samba has to maintain data structures in user space and keep those consistent across cluster nodes. One of those data structures is a central table containing SMB-level information about all file open instances.

This talk will describe the semantics to be implemented, the challenges for clustered implementations of the SMB protocol and approaches by the Samba Team to make this scale well across nodes."

Teaser SDC 2019 talks by SerNet

At the Storage Developer Conferenece (SDC) last year (September 23 - 26, 2019, Santa Clara/California), Volker Lendecke and Ralph Böhme, both part of SerNet and the international Samba Team, gave presentations. These are available on the SNIA YouTube channel.

Ralph Böhme: What's new in Samba?
Direct Link:
Abstract: Presenting an overview on the latest advancements, new features and changes in Samba. The key focus is on Samba's SMB3 fileserver implementation, while also covering recent enhancements in Clustered Samba and Samba's implementation of Active Directory.

Volker Lendecke: Samba's RPC Services for non GPL SMB Servers
Direct Link:
Abstract: Implementing [MS-SMB2] is a first step towards Windows interoperability. The simple task of listing shares is a nontrivial challenge, because Windows uses the srvsvc RPC service for this. Samba provides a seamless Windows user experience, it implements both SMB and RPC. It does so in a way that can be easily split apart in a GPL-compatible manner without putting GPL requirements on the SMB implementation. This talk presents a project where a non-GPL SMB implementor uses Samba's RPC implementation to provide a share listing and other RPC-based services, providing a much shorter time to market than by implementing the RPC stack independently. The talk also covers ways forward how Samba could implement a full RPC stack usable for simple integration of other RPC-based services.

Volker Lendecke:  Progress in making clustered Samba more scalable
Direct Link:
Abstract: This talk is a sequel to the 2018 talk about how to make Samba really fly in a clustered environment (direct link). It provides insights on the progress of the deep restructuring of Samba's core data structures as well as plans to optimize both the isolated as well as the heavily concurrent, shared file access that suffers from significant lock contention on internal data structures.
