June development review: Writing to FUSE on Red Hat installs
A couple of major new developments landed in the last Arvados development sprint. Whether you're using Arvados to analyze data, administering it in your lab, or both, you'll find something to like.
Users can now write files in our FUSE driver. When you enable this feature, new data you write will be uploaded to Keep, and all your changes will update the Arvados collection on the API server. Of course, data is never lost; every byte is still in Keep, and previous versions of collections can be identified by their content address. Now you have even more ways to combine existing data analysis tools with Arvados' rich data tracking and organizing features. Not every POSIX operation is supported yet, but this is enough to let you run interactive analysis directly on collections. Check our FUSE documentation for all the details.
Administrators now have more options for installing Arvados. We've long packaged each Arvados component for Debian 7, and we're happy to add CentOS 6.6 and Ubuntu 12.04 to our list of supported distributions. Of course, we took the opportunity to update our installation guide to match—and while we were at it, we improved several sections to add useful pointers and describe how we deploy Arvados at Curoverse. All of these changes should help anyone installing Arvados on any kind of cluster to have a smoother experience.
We hope you'll try out the new features, and let us know how they work out for you. We're always happy to hear your feedback on our IRC channel or mailing list. And if you're curious but not sure how to get started, the easiest way is to sign up for our public beta.
