*** amotoki has quit IRC | 13:58 | |
nagyz | I've managed to create an LB, however, inside the amphora instance I only see one interface (with an IP from the private network) | 14:11 |
nagyz | who's responsibility is it to plug in the 2nd interface and configure it? | 14:12 |
diltram | nagyz: if I'm right this is a allowed_address_pair - so there is configured multiple IPs/MACs for this port | 14:16 |
diltram | but from neutron perspective | 14:16 |
diltram | you can check neutron port information | 14:16 |
nagyz | yes, that part is clear and is configured | 14:24 |
nagyz | however inside the instance (since the vip is not being configured as a floating IP), there should be two interfaces now, right? | 14:24 |
nagyz | eth0 and eth1, eth0 being on the private network and eth1 being on the external | 14:25 |
nagyz | my understanding is that now eth1 should have one IP (the instance IP) and an alias IP (the allowed pair) | 14:25 |
nagyz | is that not right? | 14:25 |
nagyz | however the allowed address pair's port is in the DOWN state | 14:28 |
diltram | if yours allowed address pair is down something is wrong | 14:33 |
diltram | you're using kvm as hypervisor? | 14:34 |
diltram | or qemu? | 14:34 |
*** ducttape_ has joined #openstack-lbaas | 14:35 | |
nagyz | kvm | 14:38 |
diltram | so it suppose to work | 14:42 |
diltram | normaly nova is responsible for attaching all interfaces and drives | 14:43 |
diltram | nova is asking neutron about port specification and after that is configuring everythin in xml with vm specification | 14:43 |
diltram | so you can take a look in nova compute logs to check if there are some problems with attaching that interface | 14:44 |
diltram | ping johnsom | 14:44 |
diltram | ping any core :D | 14:45 |
vrathi | I pinged johnsom he told me to enable nested virtualization i enabled it but still not working | 14:47 |
diltram | nagyz, vrathi: I just started a new amphora and I have also only one IP | 14:55 |
diltram | and if I'm right there should be only one IP | 14:56 |
diltram | because there is no listeners added | 14:56 |
johnsom | Hi, I don't have time to chat long as I have a meeting coming up. Note that the VIP and member networks are all inside the netns, so you must use "ip netns exec amphora-haproxy <command/bash>" to see them | 14:56 |
diltram | johnsom: true, my is configured properly so nagyz yours probably also :P | 14:58 |
diltram | ping rm_work | 14:59 |
diltram | anyone knows how to slow down execution of taskflow? | 14:59 |
vrathi | diltram can i see your local.conf | 14:59 |
diltram | vrathi: https://gist.github.com/diltram/a037e215c206957b703ad834953ecfa7 | 15:01 |
diltram | it's specified to use my review code but you can replace that enable_plugin line with normal octavia repo | 15:01 |
diltram | also you can copy that file into devstack directory https://gist.github.com/diltram/7d42d009b90786e809226559f1e578ae | 15:03 |
diltram | it's generating clients, load balancers and all needed to work | 15:04 |
vrathi | diltram http://docs.openstack.org/developer/devstack/guides/devstack-with-lbaas-v2.html is there any problem in this devstack configuration because I am not able to create lb on public subnet with this | 15:06 |
diltram | vrathi: I don't know what is wrong, but currently we're not able to create load balancers on public networks - because of that we're not able to use octavia as load balancer for public openstack apis | 15:07 |
diltram | plus you should disable n-net - I don't know why noone configured that | 15:08 |
diltram | with that local.conf file you have nova-net and neutron configured | 15:09 |
diltram | ok, maybe not | 15:09 |
diltram | first enabled_services line disables it | 15:09 |
*** saju_m has joined #openstack-lbaas | 15:10 | |
diltram | but yeah, I heard that there is no possibility to connect load balancer to public network currently | 15:10 |
diltram | and there is some bug/rfe/other about that to enable that functionality to use octavia as load balancer for all openstack public apis | 15:10 |
*** diogogmt has joined #openstack-lbaas | 15:11 | |

johnsom | diltram vrathi I have successfully created an LB with the VIP on public network. I thought diltram did as well. The routing for public is a bit odd, but the LB should come up and work from the public namespace | 15:19 |
vrathi | johnsom as you told me to enable nested virtualization I enable it but it still shows me error | 15:24 |
johnsom | vrathi Can you gist the o-cw log? | 15:25 |
diltram | vrathi, johnsom trying | 15:25 |
vrathi | johnsom can you send your local.conf | 15:27 |

johnsom | +1 | 15:31 |
diltram | johnsom: you have VIP configured in netns? | 15:32 |
johnsom | Yes, all customer facing traffic (VIP and member networks) are in a netns with haproxy and keepalived. This is for security isolation | 15:33 |
diltram | johnsom: but do you have them configured, you have a working public IP in devstack? | 15:34 |
johnsom | vrathi Can you double check that nested virtualization is working: cat /proc/cpuinfo| egrep "vmx|svm" | 15:34 |
*** yamamoto has joined #openstack-lbaas | 15:34 | |
diltram | because in my situation there is amphora, rest_api_driver send request to plug VIPs but there is nothing configured in netns | 15:35 |
johnsom | All of the netns is handled inside the amphora, the controller does not need to know about it. | 15:36 |
diltram | octavia.amphorae.drivers.haproxy.rest_api_driver [-] request url https://192.168.0.9:9443/0.5/plug/vip/172.24.4.12 request /opt/stack/octavia/octavia/amphorae/drivers/haproxy/rest_api_driver.py:222 | 15:37 |
diltram | log from o-cw | 15:38 |
diltram | and it's not configured | 15:38 |
johnsom | diltram If you log into the amp, then run "sudo ip netns exec amphora-haproxy ip a" You should see the IP 172.24.4.12 | 15:39 |
diltram | no, there is no IP configured | 15:39 |
diltram | namespace is properly created, eth1 is there | 15:40 |
johnsom | diltram have you created a listener? | 15:40 |
*** sanazz has joined #openstack-lbaas | 15:40 | |
diltram | but no ip is configured | 15:40 |
diltram | no | 15:40 |
diltram | johnsom: Octavia reverted and killed that amphora | 15:41 |
diltram | johnsom: https://gist.github.com/diltram/8f28cafb077d492c3aa62b5fd7bef05b | 15:45 |
diltram | where i can find logs from amphora-agent? | 15:46 |
rm_work | diltram: hey, i'm around | 15:49 |
rm_work | btw diltram, this is how I do my stacks: https://github.com/rm-you/devstack_deploy/blob/master/stackme.sh | 15:49 |
rm_work | diltram: makes it easy to select patchsets | 15:50 |
diltram | rm_work: I forgot that you're not interacted with taskflows :P | 15:50 |
diltram | I know | 15:50 |
diltram | that second gist is from you | 15:50 |
diltram | :) | 15:50 |
rm_work | yeah I haven't touched taskflow much... i don't know that you can "slow them down"? | 15:50 |
diltram | I need to do something to wait for the update in db | 15:51 |
diltram | I have a race condition, yay :/ | 15:51 |
rm_work | hmm | 15:51 |
diltram | We have a database_task.allocate_and_associate and it's accepting loadbalancer_id and should return amphora_id | 15:53 |
diltram | but amphora is still in pending_create state so it's not returning that id and all flow is dead | 15:54 |
johnsom | diltram, you aren't using the subflow like failover is? | 15:55 |
diltram | and I don't know what I should do with this, add some task wait_for_active_amphora or what | 15:55 |
diltram | yes, there is get_amphora_for_lb_subflow used but it's not veryfing that this new amphora is already created | 15:55 |
johnsom | The failover flow is setup correctly for this | 15:56 |
diltram | true, and that part of code is working for me OK | 15:57 |
diltram | but after that were running _get_post_map_lb_subflow(self, prefix, role): | 15:57 |
diltram | which is also reloading amphora | 15:58 |
johnsom | After the bug was fixed | 15:58 |

rm_work | hmm | 16:04 |
diltram | and it's a race condition | 16:04 |
diltram | enabling debug resolve that issue :P | 16:04 |
rm_work | can you put a retry/wait? | 16:04 |
rm_work | seems ugly though... | 16:04 |
diltram | I was thinking about that | 16:04 |
*** sanazz has quit IRC | 16:05 | |
diltram | or about adding some task like wait for create/active | 16:05 |
