I've not looked at each of them yet and I would very much appreciate your advice about the best way to proceed. http://tracker.ceph.com/issues/16511 http://tracker.ceph.com/issues/16512 http://tracker.ceph.com/issues/16658 http://tracker.ceph.com/issues/16701 http://tracker.ceph.com/issues/16747 http://tracker.ceph.com/issues/16902 http://tracker.ceph.com/issues/16978 Maybe they should be cherry-picked in a specific order in order to avoid conflicts ? For instance, maybe one of the pending backports that you can see at https://github.com/ceph/ceph/pulls?q=is%3Aopen+is%3Apr+milestone%3Ajewel+label%3Arbd would avoid some of the conflicts if merged ? I'm thinking specifically https://github.com/ceph/ceph/pull/10646 https://github.com/ceph/ceph/pull/10644 What I'm looking for, ideally, is a way to order the cherry-picks to avoid any conflict. That may involve backporting a few additional pull requests (for instance when the type of an argument changes from int64_t to uint64_t, that creates a lot of potential conflicts and backporting that change could help, even if it is not required to fix a given bug. There are three backports that also do not apply because of a conflict but do not seem to be related to rbd-mirror. Unless you advise otherwise, I'll attempt to resolve these individually and assume there is complex interaction with other backports. http://tracker.ceph.com/issues/16950 http://tracker.ceph.com/issues/16904 http://tracker.ceph.com/issues/16735 Thanks in advance for your guidance ! -- Loïc Dachary, Artisan Logiciel Libre
