Cephalocon 2024

You’ve built an amazing new feature for your Ceph use case and want to share it with the world. Now what? You make a pull request! Learn how to prepare and present your new work effectively and successfully within the Ceph community, and understand what you can expect from other contributors who are reviewing it. 
Conversely, you are asked to review a PR, and maybe it needs work. How do you share feedback in a way that it’s heard and handled? Which feedback is worth sharing at which stage of the process? And what are you promising to everybody else when you provide that “Reviewed-by” tag? This talk is for anybody who writes or reviews code (or wants to!) in the Ceph project. Prepared and presented by two of Ceph’s original four tech leads, hear about pitfalls and tips developed submitting PRs, mentoring new developers, and reviewing code from drive-by contributors, Ceph startups, consultancies, and future maintainers!

Is 2024 the year of SMB on Ceph? It was for me. In his talk I will discuss the progress of our effort to add managed SMB suport to Ceph. Focusing primarily on the Orchestration aspects of this work, I will talk about some of the major steps it took to integrate Samba with Ceph, some of the projects outside Ceph that help make it happen, and some of our future plans. We will look into the commands needed to set up an SMB Cluster and Shares and demonstrate the workflow involved in connecting some Windows and Linux clients to an SMB Share using Active Directory authentication.

// What if... there is a 24*7 running Ceph cluster at every home? // What is CephBox project? A DIY opensource Home cloud NAS solution with Ceph as the backbone. Why CephBox? A product must be a solution to real world problem: Cloud storage for personal use is 'expensive' and 'superfluous', whereas the external Hard drives and USB stick which we use as alternative have a short 'shell life'; waiting for the memories to be lost forever. Although personal data doesn't have high monetary value associated to it like enterprise business data, it has tremendous emotional value. There should be a de-centralized hybrid solution for personal data storage without cutting off the benefits of cloud storage. I would like to present my research and experience of building a small but efficient Ceph cluster on Raspberry pi servers to manage the storage needs of my family and myself. Agenda : Building a Ceph cluster on Raspberry pi servers. Why is CephBox better than other NAS alternatives. How to use S3 apps to store and automatically backup photos from the phone in the home network. How to create a 3-2-1 storage solution with CephBox which guarantee lifetime longevity of your personal data.

This talk will provide an overview of the new features and notable improvements in Ceph's block device component, RBD, in the Squid release. We will discuss topics such as the new feature to mirror RBD groups, improvements in live-migrating RBD images, various performance optimizations in RBD, and improved support for Windows. The session will also cover what's next for RBD in the Tentacle release. The goal is to keep new and experienced RBD users up-to-date with the latest that RBD has to offer and future plans for RBD.

In this talk, we delve into the integration of snapshots as shadow copies within CephFS, emphasizing their utilization and management from a Windows client perspective through Samba. The focus will be on the vfs_ceph_snapshots module, which facilitates the seamless presentation of CephFS snapshots as volume shadow copies to Windows clients. This capability is effective both in environments using kernel mounts and those employing the ceph VFS module, offering a flexible approach to snapshot management. We will conduct practical demonstrations to showcase the process of creating, accessing, and restoring these snapshots, while also evaluating the observations made. Furthermore, the presentation will outline future plans aimed at enhancing the reliability and versatility of this functionality, ensuring it meets the evolving needs of users.

Introducing the new Pulpito interface with unique features, including job scheduling from web, one-click run termination, rerunning and sharing saved command configurations, and more! This talk will walk you through all the new capabilities and tricks of Pulpito-NG, which streamline the entire Teuthology experience.

Encrypting data in large storage platforms like Ceph has become a standard practice in the industry. However, when attempting to utilize these features in Ceph, a typical user may find the process overwhelming. One reason may be the lack of a consolidated Ceph Docs document that explains and compares the various encryption solutions available in Ceph. This could assist Ceph users in identifying the optimal solution for their specific use case. My objective is to provide a foundational overview of data encryption in Ceph and clarify the various encryption solutions currently available within Ceph. At the end I will talk about that none of the Ceph encryption solutions give a storage end-user the ability to figure out if someone other than authorized parties have tampered with the data. Therefore I will present a method on how to solve the problem. Our solution is to integrate AEAD ciphers into Ceph (as done in Azure,Google Cloud,AWS) and use OMAP to store the resulting authentication tags. My goal is to initiate a dialogue within the community to ascertain whether the solution I have developed is applicable within the context of Ceph and to get guidance on how to proceed from here
