Build and validate a scale-out Samba/CTDB cluster atop CephFSan invention by dmdiss Samba and CTDB rely heavily on POSIX fcntl locks for data and meta-data integrity. This functionality was recently fixed in CephFS, opening up the possibility to use CephFS as an underlying filesystem for a scale-out Samba/CTDB cluster. Such an architecture should perform and scale much better than the existing single Samba + VFS module gateway.

[ARM] Ceph on AArch64an idea by algraf Octopuses have many ARMs, so we should definitely allow them to run on them too! Today, we don't have working Ceph packages for AArch64, but already solid interest from customers asking us about it. It would be great to be able to give them something to play with. |
Ceph RBD backed USB mass storage gadgeta project by dmdiss Create a USB device that, when configured and connected, exposes one or more Ceph RBD images for use as USB storage, allowing for: * Ceph storage consumption by almost any system with a USB port

Native Xen support for RADOS Block devicesa project by jfehlig libvirt+Xen should support the qdisk (qemu) rbd backend, providing native access to block devices hosted on Ceph clusters. Adding this support to the libvirt+Xen toolstack will also improve interoperability with SUSE Enterprise Storage.

Orca: hunting cephalopods for fun and dinnera project by LarsMB Orcas are amazing animals. They are playful, intelligent, great swimmers, and very social. They also love to play with their food, hunting down their prey with advanced strategies - understanding where its prey hides, how it will try to escape, and how to overcome those tactics - and having a lot of fun doing so, before relentlessly tearing it apart, killing it, and eat it. Not necessarily in that order. Oh, and they have the right color scheme. This forces their prey to also improve and adapt more advanced strategies and tactics. In this arms race, both sides evolve and improve: the evolutionary pressure has made cephalopods highly intelligent, adaptable, and resilient. Unfortunately (for them), they are still very tasty. So we should exert more evolutionary pressure on individuals to help them stay alive as a species.

Boot system from Ceph RADOS Block Devicean idea by dmdiss Write a new Dracut module which adds support for booting a system where the root filesystem resides on a remote RBD image. * Pack keyring and ceph.conf (monitor address) in the initramfs image |
Add Ceph support for Azure RESTful protocolsan idea by dmdiss Microsoft Azure offers a bunch of interesting RESTful protocols, providing access to objects (Block Blobs, similar to S3 Objects), disk images (Page Blobs) and file systems (Azure Files). The underlying services seem to map pretty closely to RADOS, RBD and CephFS respectively, so adding support for these protocols to Ceph, despite being a lot of work, should be relatively straightforward. I've already worked on implementing a C client for these protocols via Elasto, so it might be worth reusing the same code in implementing the server functionality atop the public librados / librbd / libcephfs libraries. The other option would be to use civetweb/rgw, which is already embedded within Ceph for S3/SWIFT gateway support. |
Use Ceph RADOS key-value store as a dbwrap backend for Sambaa project by dmdiss Ceph offers a highly scalable and fault-tolerant storage system. Samba is already capable of sharing data located on the Ceph Filesystem, however scale-out sharing (the same data exposed by multiple Samba nodes) currently requires the use of CTDB for consistent and coherent state across Samba cluster nodes. In such a setup CTDB provides a clustered database with persistent key-value data storage and locking. Database usage is abstracted out via a generic dbwrap interface. Ceph's librados library provides an API for the storage and retrieval of arbitrary key-value data via the omap functions. A watch/notify protocol is also provided as a mechanism for synchronising client state (locking). Key-value data stored in the RADOS back-end inherits the same redundancy features as regular objects, making it a potentially good candidate as a replacement for CTDB in scale-out Samba clusters.

Storage War Gamesa project by jluis When we started brain storming a project for hack week, one of the floated ideas was to remake the 1983 film WarGames, and for lack of available space, a local lot with storage units was proposed. Over the course of the following years, while we planned, we realized that this whole idea would not be the most feasible, but it still felt like we were onto something. Eventually, we settled with keeping the name and changing the scope.
