There was a problem hiding this comment.
Just noting the new requirement of local temporary storage on the host driving the adoption. We already have the control plane YAML files there so it's not the first local file requirement. And it's probably better than the alternatives like giving some pod a permission to ssh into the controllers. So +1.
With current backup/restore uuids for the records are being changed and that's result into geneve tunnels to be disabled with the compute nodes and thus centralized SNAT traffic is impacted when ovn_controller are started post adoption on the networker nodes. The traffic remains impacted until ovn_controllers are started also on the compute nodes. So to fix this switch to use full db files for restoration after converting the DBs to standalone. With this also cleaned the unused resources. Resolves: #OSPRH-29914 Signed-off-by: Yatin Karel <ykarel@redhat.com>
