Dear All, We were able to solve the issue. The problem was after the reboot rabbitmq is overloaded because ceilometer started after the reboot which was in stopped state. Due to this the controller nodes resource utilization was very high and cpu cores maxed out. As a result we got timeouts in our neutron and rabbitmq logs. We stopped the ceilometer components both on controllers and compute nodes, cleaned the ceilometer queues from rabbitmq, emptied the ovsdb and restarted the neutron components in all the controllers. Then slowly all the tags in ports are recovered and VM's are reachable. On Wed, Apr 10, 2019 at 7:15 PM Jakub Libosvar <jlibosva@redhat.com> wrote:
Is your ovs-vswitchd process running on controllers? Sounds like agent can talk to ovsdb (it was able to connect) but then times out when waiting for response from vswitchd process.
Do these command run successfully on the problematic controller? ovs-vsctl show ovs-ofctl show br-int

Dear All,
We did a minor upgrade on our OpenStack environment Newton HA cluster from 14.2.12 to 14.2.16 using the following link.
https://docs.openstack.org/openstack-ansible/newton/upgrade-guide/minor-upgr...
The upgrade was successful and we tested creation of VM's and it was also successful we were able to ssh into the VM's.
Then we rebooted the controllers one by one. But after that we can create the VM's but it is not getting IP from dhcp agent.
In the openvswitch-agent.log we are getting 'OVS transaction timeout'.
Any
help is much appreciated.
