upgrade suite: test that changes to crush maps are handled properly mid-upgrade
Added by Greg Farnum almost 10 years ago.
Updated over 9 years ago.
Description
We had some issues with users making changes to crush under mixed clusters while upgrading to Firefly (see #8738).
We should add upgrade tests that cover this functionality to make sure we don't get similar regressions in the future.

Greg, we have tests to adjust crush tunables to specific profiles like 'ceph osd crush tunables firefly' during an upgrade in the existing upgrade suites.
are you talking about this, or making other changes to crush map?
if otherwise, can you please give some examples?
The user did a tunables change and crashed. We hadn't detected it in our tests. If our tests change tunables while the OSDs are of mixed versions, and they are newer than that bug, I think this ticket is probably done!
