    v0.23 released

    Another month, and v0.23 is out.  The main milestone here is that clustered MDS is pretty stable.  Stable enough that, if you’re interested and willing, we’d like you to try it and let us know what problems you have.  Notably, clustered recovery is not yet well tested (that’s v0.24), so don’t do this unless you’re […]

    v0.22 released

    It’s a bit late, but v0.22 is here.  The original goal for this release was to have a stable clustered MDS that we can encourage users to test.  Unfortunately, we did not quite make that mark: there are still a couple significant bugs we’re working on, and I don’t want to push this release back […]

    v0.21 released

    It’s been a while, but v0.21 is ready.  Most of the work this time around has been on stability. There is one key new feature, however: RBD, the rados block device, which let you create a virtual disk backed by objects stored in the Ceph cluster.  The images can be mapped natively by the ceph […]

    Linux v2.6.34 is out

    Linux v2.6.34, which includes the Ceph kernel client, has been released!  This is an exciting milestone for us, and we’re pretty happy with the stability of the client code that made it into this release.  This should make it easier for people to experiment with Ceph and see how it holds up on a wide […]

    v0.20 released

    After a long few weeks of debugging, we’re releasing v0.20.  The goal here is to get something out prior to the v2.6.34 kernel release (which includes the Ceph client) with most of the pending improvements.  Changes since v0.19 include: osd: new filestore, journaling infrastructure.  (lower latency writes, btrfs no longer strictly required) msgr: wire protocol […]

    v0.19 released

    The v0.19 release is finally here.  The focus this past cycle was on stability and the disk format, and things have improved greatly in that area.  Our plan is to make any future disk format changes roll forward, so that users won’t need to rebuild their file systems.  The protocol has also grown feature bits […]
