I'm trying to do test them neutron-ovs-cleanup service runs earlier than ovsdb-server sometimes. then, neutron-ovs-cleanup service's status remains failed with below error msg "ProcessExecutionError: Exit code: 1; Stdin: ; Stdout: ; Stderr: ovs- vsctl: unix:/var/run/openvswitch/db.sock: database connection failed (No such file or directory)" that is fine for booting. but. If someday upgrade pkgs related to neutron, it runs neutron-ovs- cleanup again because it is not in active status. eventually, neutron-ovs-cleanup deletes all ports on running compute nodes. related logs here https://paste.ubuntu.com/p/QkkwP2vPDv/ [Test Case] 1. deploy openstack env 2. run below scripts to add many ports #!/bin/bash juju ssh nova-compute/0 ' sudo modprobe dummy for i in {1..1000} do echo $i sudo ip link add dummy$i type dummy;sudo ip link set name t-test$i dev dummy$i;sudo ovs-vsctl add-port br-int t-test$i done ' 3. systemctl list-units --failed - check if there is failed neutron-ovs-cleanup service [Regression] Changes dependency on debian/neutron-openvswitch-agent.neutron-ovs-cleanup.service.in need to reboot if this patch is affected.
