Open Stack

The qrouter netns appears once the lock_path is specified, the neutron router is pingable as well. However, instances are not pingable. If I log in via console, the instances have not been given IP addresses, if I manually give them an address and route they are pingable and seem to work. So the router is working correctly but dhcp is not working.

No errors in any of the neutron or nova logs on controllers or compute nodes.

There is no lock path set in my neutron configuration. Does it ultimately matter what it is set to as long as it is consistent? Does it need to be set on compute nodes as well as controllers?

Did you set a lock_path in the neutron’s config?

The following errors appear in the neutron-linuxbridge-agent.log on both controllers: http://paste.openstack.org/show/724930/

No such errors are on the compute nodes themselves.

Running `openstack server reboot` on an instance just causes the instance to be stuck in a rebooting status. Most notable of the logs is neutron-server.log which shows the following:
http://paste.openstack.org/show/724917/

I realized that rabbitmq was in a failed state, so I bootstrapped it, rebooted controllers, and all of the agents show online.

And all of the instances can be properly started, however I cannot ping any of the instances floating IPs or the neutron router. And when logging into an instance with the console, there is no IP address on any interface.

Try restarting them using "openstack server reboot" and also check the nova-compute.log and neutron agents logs on the compute nodes.

We just suffered a power outage in out data center and I'm having trouble recovering the Openstack cluster. All of the nodes are back online, every instance shows active but `virsh list --all` on the compute nodes show that all of the VMs are actually shut down. Running `ip addr` on any of the nodes shows that none of the bridges are present and `ip netns` shows that all of the network namespaces are missing as well. So despite all of the neutron service running, none of the networking appears to be active, which is concerning. How do I solve this without recreating all of the networks?
