| * MGR: The pg_autoscaler can now be turned `on` and `off` globally | ||
| with the `noautoscale` flag. By default this flag is unset and | ||
| the default pg_autoscale mode remains the same. | ||

nit: should be under 16.2.8 now
`noautoscale` flag is a feature where the user can choose to flip the switch between turning autoscale `on` and `off` for all pools with a single command. `osd pool set noautoscale` will turn all autoscale mode`off` for all pools. `osd pool unset noautoscale` will turn all autoscale mode `on` for all pools. Signed-off-by: Kamoltat <ksirivad@redhat.com> (cherry picked from commit be17f04) Conflicts: src/pybind/mgr/pg_autoscaler/module.py - trivial fix
set and unset the noautoscale flag, evaluate if the results are what we expected. As well as, evaluate if the flag is correct when we create new pools. Signed-off-by: Kamoltat <ksirivad@redhat.com> (cherry picked from commit bb42c71) Conflicts: test-noautoscale-flag.yaml - modified pre-mgr-command to not create device health monitor
Updated the docs in https://docs.ceph.com/en/latest/rados/operations/placement-groups/ and updated the release notes to reflect noautoscale flag. Signed-off-by: Kamoltat <ksirivad@redhat.com> (cherry picked from commit 9baed03) Conflicts: PendingReleaseNotes - trivial fix
