What is HekaFS
HekaFS (formerly CloudFS) is built on top of Gluster. It provides a set of translators to make Gluster more suitable as a cloud file system. HekaFS is a feature for the Fedora 16 release, and the Fedora Cloud special interest group (SIG) is actively involved in development and testing.
The Fedora HekaFS feature page has information about the status of HekaFS as a feature in a future release of Fedora.
See Jeff Darcy's HekaFS blog to learn more about the philosophy of HekaFS and find out what's happening with HekaFS development.

How to use HekaFS
General HekaFS discussions are at: https://fedorahosted.org/mailman/listinfo/cloudfs-general
Red Hat Cloud OpenShift uses HekaFS. The user community for that product is found at: http://www.redhat.com/openshift/forums
Here's a guide to setting up a simple HekaFS Cluster.
How to participate in HekaFS
Let's start with some important links.
- The upstream project overview (slides, blog posts) is at http://hekafs.org/cloudfs-overview/
- The source repository is at: http://git.fedorahosted.org/git/?p=CloudFS.git
- The developer mailing list is at: https://fedorahosted.org/mailman/listinfo/cloudfs-devel
- The user mailing list (pretty empty so far) is at https://fedorahosted.org/mailman/listinfo/cloudfs-general
HekaFS is still under active development, so there are still many ways to contribute. Here are some possibilities.
- Use it, report bugs, suggest features. The packaging and documentation are still works in progress, so this might require some interaction with one of the developers, but we don't bite. Feel free to contact firstname.lastname@example.org, email@example.com, or firstname.lastname@example.org - all the same person - and I'd be delighted to help you through it.
- Use the upstream (http://gluster.org), report bugs, suggest features. For the most part, HekaFS is GlusterFS with a couple of extra bits, so many of the issues you're likely to experience are actually GlusterFS issues. HekaFS is not just its own code, though. It's also a sort of unofficial "CloudFS SIG" within the GlusterFS community. If you want GlusterFS fixes or enhancements because of your interest in HekaFS, we can drive those as part of HekaFS.
- Say hi in Freenode IRC. #cloudfs is pretty dead (let's fix that), but #gluster and #fedora-cloud are pretty lively.
- Help with documentation. There are several bits of documentation in the source tree, but a little loving from a genuine wordsmith would go a long way.
- Improve the core code. Some parts of HekaFS are practically done, but others are still in active development and there's still plenty of room for more developers. In particular, if you're a security/cryptography expert, more review of those pieces would be most welcome. People might look at HekaFS as a more secure alternatives to Dropbox or Jungledisk, both of which have had problems in this area recently, so this is a great area to focus on. Despite being a file system this is not kernel code, by the way. It should be relatively free of those additional complications and comprehensible to non-kernel programmers.
- Get the word out. The number of participants is directly proportional to the number of people who've heard about it, and some people who might want to contribute might not even know we're here. Blog, tweet, whatever, let people know that there's an open-source project to create a scalable, secure, multi-tenant filesystem.
