    More Than an Object Store

    Today, Dmitry Ukov wrote a great post on the Mirantis Blog entitled Object Storage approaches for OpenStack Cloud: Understanding Swift and Ceph. Dmitry’s overview on Ceph was a solid introduction to those needing an object store for their OpenStack deployment, and it was an interesting read. Thanks, Dmitry! Naturally, since I spend most of my […]

    Summer Adventures with Ceph: Building a B-tree

    Greetings! I am a summer intern at Inktank. My summer project is to create a distributed, B-tree-like key-value store, with support for multiple writers, using librados and the Ceph object store. In my last blog post, I wrote about the single client implementation I created to start out with. Over the last several weeks, I’ve […]

    v0.48.1 ‘argonaut’ stable update released

    We’ve built and pushed the first update to the argonaut stable release.  This branch has a range of small fixes for stability, compatibility, and performance, but no major changes in functionality.  The stability fixes are particularly important for large clusters with many OSDs, and for network environments where intermittent network failures are more common. The […]

    v0.49 released

    This release is a bit less exciting than most because it is the first development release since argonaut, and much of our time has been spent working on stability.  Most of those fixes have been backported and slated for the next argonaut point release (v0.48.1).   I’ll include both below; see the 0.48.1 release notes […]

    We’re pleased to annouce the release of Ceph v0.48, code-named “argonaut.”  This release will be the basis of our first long-term stable branch.  Although we will continue to make releases every 3-4 weeks, this stable release will be maintained with bug fixes and select non-destabilizing feature additions for much longer than that.  Argonaut is recommended […]

    My First Impressions of Ceph as a Summer Intern

    Hi! My name is Eleanor, and I’m working on Ceph as an intern for Inktank this summer. My task for the summer is to use the Ceph API to create a lock-free, distributed key-value store suitable for storing large sets of small key-value pairs. I’ve just finished my first year at Pomona College, where I’m […]

    This is a bugfix release with one major fix and a few small ones: osd: disable use of the FIEMAP ioctl by default as its use was leading to corruption for RBD users a few minor compile/build/specfile fixes I was going to wait for v0.48, but that is still several days away.  If you are […]
