| mfisch | klindgren_: I've been pretty disappoined in kilo so far, sounds like you're having issues too | 00:17 |
|---|---|---|
| klindgren_ | mfisch, nothing terrible - yet | 00:18 |
| klindgren_ | ipset race conditions seems to be the only thing so far | 00:18 |
| mfisch | we're having dhcp issues | 00:18 |
| mfisch | above and beyond what we presented in PA | 00:19 |
| klindgren_ | hrm what specifically re: dhcp? | 00:19 |
| mfisch | dhcp agents losing their brain and tenant VMs losing connectivity when the lease times out | 00:19 |
| klindgren_ | to be honest -we use config-drive to statically IP that stuff... | 00:20 |
| klindgren_ | so | 00:20 |
| klindgren_ | dhcp might be broken - but we don't notice ^_^ | 00:20 |
| mfisch | good choice | 00:21 |
| klindgren_ | Curious - as after mfisch talked about it.... anyone else here have issues with dhcp_agent getting moved between nodes for apparently no good reason? | 00:24 |
| klindgren_ | we've staitcally assigned dhcp_agents to specifical networks since havana - under kilo the assigments started randomly getting switched around | 00:25 |
| mfisch | my honest advice would be wait on kilo too | 00:25 |
| klindgren_ | mfisch, want to do a ML post? I can chime in on what we have seen - see if we can get more people on it. | 00:26 |
| mfisch | I'd need to work with eric on it | 00:27 |
| mfisch | he did more digging | 00:27 |
| mfisch | we did file a bug | 00:27 |
| klindgren_ | got the bug refrence? | 00:27 |

| gfa | mfisch: our dhcp lease time is like a year long. we don't have problems with that. on havana we have issues when the dhcp-agent don't notify dnsmasq about the lease being released and dnsmasq refusing to give that ip again. but since icehouse is ok | 01:55 |
| mfisch | I suggested that as a fix | 01:56 |
| mfisch | but it just masks stuff | 01:56 |

| klindgren | can you check to see if you have "port_unbound(): net_uuid None not in local_vlan_map" repeating in your openvswitch-agent logs | 16:44 |
| * jlk is hoping these are problems specific to OVS | 16:44 | |
| klindgren | since 8/12 I have ~1.5 million entires for that in logstash | 16:44 |
| klindgren | each server repeating that log message with a req-id thats the same - but seems to be unique per server | 16:45 |

| klindgren | ugh - we had to nuke some logstash data due to the fact that neutron ipset looped every second dumping a full iptables-restore output at trace level. So its probably been doing that for longer than that. | 17:00 |
