While testing upgrades as part of [0], updating the docs in [1], it became clear that during manual maintenance for munging state during chain upgrades procedures, we want all the nodes to be reset together. Therefore if maintenanceMode=true, we'll also disable the readinessProbes, otherwise the rollout will be staged, forcing us to upgrade each node in term, rather than being able to parallelize them. Now, we can
pd export
and backup state, then update the statefulset to bump the container version (to the post-upgrade version), and restart it in maintenance mode to continue with thepd migrate
step and resulting copying around of emitted files.[0] #4055
