[Openstack] [Openstack-operators] Recovering from full outage


The neutron-metadata-agent service is running, the the agent is alive, and it is listening on port 8775. However, new instances still do not get any information like hostname or keypair. If I run `curl 192.168.116.22:8775` from the compute nodes, I do get a response. The metadata agent is running, listening, and accessible from the compute nodes; and it worked previously.

I'm stumped.

Hi Torin,

If I run `ip netns exec qrouter netstat -lnp` or `ip netns exec qdhcp netstat -lnp` on the controller, should I see anything listening on the metadata port (8775)? When I run these commands I don't see that listening, but I have no example of a working system to check against. Can anybody verify this?

Either on qrouter/qdhcp namespaces, you won't see port 8775, instead check whether meta-data service is running on the neutron controller node(s) and listening on port 8775? Aslo, you can verify metadata and neturon services using following commands

service neutron-metadata-agent status neutron agent-list  netstat -ntplua | grep :8775

Thanks & Regards
Arun
