This document is for a development version of Ceph.
These steps should be taken when starting a new major release, just after the previous release has been tagged (vX.2.0) and that tag has been merged back into master.
X is the release we are just starting development on. X-1 is the one that was just released (X-1).2.0.
Define release names and constants¶
Make sure X (and, ideally, X+1) is defined:
[x] src/common/ceph_releases.h (ceph_release_t)
[x] src/common/ceph_strings.cc (ceph_release_name())
[x] src/include/rados.h (CEPH_RELEASE_* and MAX)
[x] src/mon/mon_types.h (ceph::features::mon::FEATURE_* and related structs and helpers; note that monmaptool CLI test output will need adjustment)
[x] src/mds/cephfs_features.h (CEPHFS_CURRENT_RELEASE)
[x] src/script/backport-resolve-issue (releases(), ver_to_release()… but for X-1)
[x] src/script/ceph-release-notes (X-1)
[x] ceph-build.git scripts/build_utils.sh release_from_version()
[x] update src/ceph-volume/ceph_volume/__init__.py (__release__)
[x] ensure that SERVER_X is defined
[x] change any features DEPRECATED in release X-3 are now marked RETIRED.
[ ] look for features that (1) were present in X-2 and (2) have no client dependency and mark them DEPRECATED as of X.
[x] mon/Monitor.h (CEPH_MON_FEATURE_INCOMPAT_X)
[x] mon/Monitor.cc (include in get_supported_features())
[x] mon/Monitor.cc (apply_monmap_to_compatset_features())
[x] mon/Monitor.cc (calc_quorum_requirements())
[x] qa/standalone/mon/misc adjust TEST_mon_features (add X cases and adjust –mon-debug-no-require-X)
[x] mon/MgrMonitor.cc adjust always_on_modules
[x] common/options.cc define mon_debug_no_require_X
[x] common/options.cc remove mon_debug_no_require_X-2
[x] mon/OSDMonitor.cc create_initial: adjust new require_osd_release, and add associated mon_debug_no_require_X
[x] mon/OSDMonitor.cc preprocess_boot: adjust “disallow boot of ” condition to disallow X if require_osd_release < X-2.
[x] mon/OSDMonitor.cc: adjust “osd require-osd-release” to (1) allow setting X, and (2) check that all mons and OSDs have X
[x] mon/MonCommands.h: adjust “osd require-osd-release” allows options to include X
[x] qa/workunits/cephtool/test.sh: adjust require-osd-release test
[ ] search code for “after X-1” or “X” for conditional checks
[ ] search code for X-2 and X-3 (CEPH_FEATURE_SERVER_* and ceph_release_t::*)
[ ] search code for require_osd_release
[ ] search code for min_mon_release
[ ] create qa/suites/upgrade/(X-1)-x
[x] remove qa/suites/upgrade/(X-3)-x-*
[x] remove qa/suites/rados/upgrade/(X-3)-x-singleton symlink
[x] create qa/releases/X.yaml
[x] create qa/suites/rados/thrash-old-clients/1-install/(X-1).yaml
First release candidate¶
[ ] src/ceph_release: change type to rc
