[6912] Octavia load balancers may not work properly with DVR

[16495] Failure to reschedule OpenStack deployment pods after a node recovery

Kubernetes does not reschedule OpenStack deployment pods after a node recovery.

As a workaround, delete all pods of the deployment:

for i in $(kubectl -n openstack get deployments |grep -v NAME | awk '{print $1}');
kubectl -n openstack rollout restart deployment/$i;

Once done, the pods will respawn automatically.

[16452] Failure to update the Octavia policy after policies removal

Fixed in MOS 21.6

The Octavia policy fails to be updated after policies removal from the OsDpl CR. The issue affects OpenStack Victoria.

As a workaround, restart the Octavia API pods:

kubectl -n openstack delete pod -l application=octavia,component=api

[16103] Glance client returns HTTPInternalServerError error

Fixed in MOS 21.6

When Glance is configured with the Cinder back end TechPreview, the Glance client may return the HTTPInternalServerError error while operating with volume. In this case, repeat the action again until it succeeds.
