    It’s been a while, but v0.21 is ready.  Most of the work this time around has been on stability.

    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 […]

    v0.19 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 […]
