Ceph v0.8 has been released.  Debian packages for amd64 and i386 have been built and there is a tarball, or you can pull the ‘master’ branch from Git.  This update has a lot of important protocol changes and corresponding performance improvements: Client / MDS protocol simplification — faster, less fragile Online adjustment of data and/or […]
