    v0.56.1 released

    We found a few critical problems with v0.56, and fixed a few outstanding problems.  v0.56.1 is ready, and we’re pretty pleased with it! There are two critical fixes in this update: a fix for possible data loss or corruption if power is lost, and a protocol compatibility problem that was introduced in v0.56 (between v0.56 […]

    v0.56 released

    We’re bringing in the new year with a new release, v0.56, which will form the basis of the next stable series “bobtail.”  There is little in the way of new functionality since v0.55, as we’ve been focusing primarily on stability, performance, and upgradability from the previous argonaut stable series (v0.48.x).  If you are a current […]

    v0.55 released

    We had originally planned to make v0.55 a long-term stable release, but a lot of last-minute changes and fixes went into this cycle, so we are going to wait another cycle and make v0.56 bobtail.   A lot of work went into v0.55, however.  If you aren’t running argonaut (v0.48.*), please give v0.55 a try […]

    v0.53 released

    Another development release of Ceph is ready, v0.53.  We are getting pretty close to what will be frozen for the next stable release (bobtail), so if you would like a preview, give this one a go.  Notable changes include: librbd: image locking rbd: fix list command when more than 1024 (format 2) images osd: backfill […]

    v0.48.2 ‘argonaut’ stable update released

    Another update to the stable “argonaut” series has been released. This fixes a few important bugs in rbd and radosgw and includes a series of changes to upstart and deployment related scripts that will allow the upcoming ‘ceph-deploy’ tool to work with the argonaut release. Upgrading: The default search path for keyring files now includes /etc/ceph/ceph.$name.keyring. […]

    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 […]
