h3. Introduction Backporting and the maintenance of a stable release begins when a new "stable Ceph release":http://ceph.com/docs/master/releases is published. Commits from the master branch are cherry-picked to the stable branch and run through integration and upgrade tests. After a few weeks a "point release":http://ceph.com/docs/master/releases is published. This repeats until the "the stable release is retired":http://ceph.com/docs/master/releases. Backporting is focused on fixing bugs and development on the master branch is expected to add new features but both share the "same workflow":http://ceph.com/docs/master/dev/development-workflow/. h3. Overview of the backports in progress * *nautilus* ** "backports":http://tracker.ceph.com/projects/ceph/issues?query_id=171 "backports": http://tracker.ceph.com/projects/ceph/issues?query_id=171 ** "pending issues":http://tracker.ceph.com/projects/ceph/issues?query_id=172 issues": http://tracker.ceph.com/projects/ceph/issues?query_id=172 ** "pull requests":https://github.com/ceph/ceph/milestone/12 requests": https://github.com/ceph/ceph/milestone/12 * *mimic* ** "backports":http://tracker.ceph.com/projects/ceph/issues?query_id=150 "backports": http://tracker.ceph.com/projects/ceph/issues?query_id=150 ** "pending issues":http://tracker.ceph.com/projects/ceph/issues?query_id=151 issues": http://tracker.ceph.com/projects/ceph/issues?query_id=151 ** "pull requests":https://github.com/ceph/ceph/milestone/11 requests": https://github.com/ceph/ceph/milestone/11 * *luminous* ** "backports":http://tracker.ceph.com/projects/ceph/issues?query_id=127 "backports": http://tracker.ceph.com/projects/ceph/issues?query_id=127 ** "pending issues":http://tracker.ceph.com/projects/ceph/issues?query_id=128 issues": http://tracker.ceph.com/projects/ceph/issues?query_id=128 ** "pull requests":https://github.com/ceph/ceph/milestone/10 requests": https://github.com/ceph/ceph/milestone/10 h3. Leads * Ceph : Sage Weil * rados : Josh Durgin * radosgw / rgw : Yehuda Sadeh * CephFS / fs : Patrick Donnelly * RBD : Jason Dillaman Note: It may be useful to know the leads of other projects which have a different lifecycle but depend on Ceph. h3. Who's who Members of the "stable releases team":http://tracker.ceph.com/projects/ceph-releases are assigned the following roles as of September, 2017. | Name | IRC nick | | Abhishek Lekshmanan | theanalyst | | Yuri Weinstein | yuriw | | Nathan Cutler | smithfarm | * Mentee: during the course of a release the driver is available to help understand the stable release workflow * Driver: responsible for making sure the release is moving forward * Backup: helps the driver and replaces her/him when she/he is not available * Sage Weil, Patrick Donnelly, Jason Dillaman, Josh Durgin, Yehuda Sadeh: leads h3. HOWTO The following describes in detail and in chronological order, the steps to follow for backporting and maintaining stable releases. h4.
