Adding Requires=neutron-ovs-cleanup.service to neutron-l3-agent.service, neutron-dhcp-agent.service, and nova-compute.service is turning out to be perhaps too tightly coupled.
Doing this would also require the binary packages for each of the above named services to depend on the neutron-openvswitch-agent binary package. This is because neutron-ovs-cleanup is installed by the neutron-openvswitch-agent binary package. If we add Requires=neutron- ovs-cleanup without adding the binary package dependency, then at install time the above named services would fail with a dependency error if neutron-ovs-cleanup is not already installed. I just did some reboot testing and I think we are ok with just the After =neutron-ovs-cleanup for these services. I rebooted 10 times and each time neutron-l3-agent and neutron-dhcp-agent started after neutron-ovs- cleanup. So I believe we are already covered for reboots. What this doesn't cover is service start order at package install time. neutron-l3-agent and neutron-dhcp-agent can be installed and started before neutron-ovs-cleanup is installed. In this case neutron-ovs- cleanup would start and run after neutron-l3-agent and neutron-dhcp- agent are started. I don't think this is a big deal at install time. As for upgrades, neutron-ovs-cleanup doesn't restart, I believe because it is Type=oneshot. So that is very good news. You can 'apt dist- upgrade' to all new neutron packages and neutron-ovs-cleanup won't get restarted. I think we should just move forward with the original issue reported by this bug and add AFter= and Requires= to neutron-ovs-cleanup. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1752838 Title: [SRU] neutron-ovs-cleanup runs earlier than ovsdb-server when there are many port To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-archive/+bug/1752838/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
