| *** cody-somerville has quit IRC | 19:30 | |
| *** cody-somerville has joined #openstack-lbaas | 19:30 | |
| nmagnezi | KeithMnemonic, IIRC, creating a pool in a given loadbalancer will move that loadbalancer to PENDING_UPDATE state until it's done creating it. So generally speaking, as long as your loadbalancer is on PENDING_UPDATE you cannot modify it | 19:33 |
| KeithMnemonic | that is what they are seeing ;-) | 19:34 |
| KeithMnemonic | If two pools are created in parallel, one request receives "Invalid state PENDING_UPDATE of loadbalancer resource xzy". | 19:34 |
| KeithMnemonic | thanks nmagnezi | 19:35 |
| nmagnezi | KeithMnemonic, so that behavior is expected :) | 19:35 |

| openstackgerrit | Adam Harwell proposed openstack/octavia master: Add availability_zone to the amphora record https://review.openstack.org/510225 | 22:47 |
| *** catintheroof has joined #openstack-lbaas | 22:47 | |
| *** jniesz has quit IRC | 22:50 | |
| kong | johnsom: do you think it makes sense that contain the amphora role in vms name? e.g. 'amphora-<amphora-id>-master' | 22:56 |
| kong | currently, the only way to figure out the amphora role is to query the database | 22:57 |
| kong | our operators want to get that information directly from the cli | 22:57 |
| kong | and also the lb id | 22:58 |
| kong | or may store such information in vm metadata? | 22:59 |
| johnsom | kong Not really. Note that the amphora change roles autonomously, so we don't know who is the current master at any one time. The database record is for how we configure those VMs, not the current state of the amphora | 22:59 |
| kong | hmm...yeah | 23:00 |
| johnsom | It's part of our layers of high availability. They can failover without the control plane running if they need to. | 23:01 |
| johnsom | Unfortunately keepalived doesn't give us an easy way to query it either to see what it's current state is. | 23:02 |
| johnsom | We were talking about that with one of the developers at the PTG in Denver. | 23:02 |
| kong | johnsom: so there is no direct way to know who is master? | 23:02 |
| kong | even from inside the amphora? | 23:02 |
| johnsom | No reliable way. You can try to parse the syslog, you could send it a signal and parse a text file (can't remember if that worked or not), or you could try to use the notify scripts to write out a status file. But otherwise there isn't a way to know. | 23:04 |
| kong | i thought it was done by health_manager... | 23:04 |
| johnsom | Health manager is another layer of HA above that. It does failover by rebuilding the instance if the failure requires it. | 23:05 |
| johnsom | keepalived (master/backup) fails over in a second or two. Health manager failover takes 30 seconds up to 10 minutes depending on your cloud and nova performance. | 23:06 |
| kong | ok, the second question, how about including lb id in the vm name or metadata or tag? | 23:07 |
| johnsom | The amphora ID is in the VM name | 23:08 |
| kong | i mean, the lb id | 23:08 |
| kong | the ops want more information without querying directly from the db, if the information is easy to set by octavia | 23:10 |
| johnsom | I guess it could be added to the instance metadata. I guess we just haven't had a use case for it since we track by amphora (LBs will have one or more amphroa) | 23:10 |
| kong | the problem is we could only get amphora inforamation from database, which is what the ops want to avoid | 23:11 |
| johnsom | Yes, we intentionally hide that information. | 23:11 |
| johnsom | kong You can now get that information via the Admin API: https://developer.openstack.org/api-ref/load-balancer/v2/index.html#list-amphora | 23:13 |
| *** tongl has quit IRC | 23:14 | |
| johnsom | That said, if there is a good use case for adding the lb ID to the nova instance, I don't think it would be hard to do. | 23:14 |
| kong | johnsom: hmm...it's in Queeen :-( | 23:15 |
| johnsom | Yep. So would adding it to the metadata.... | 23:15 |
| kong | ok, will leave it for now. I think the amphora api is what we want. Even if i can contribute to add lb id to vm's metadata, the feature will be still be avalable in Queen | 23:17 |
| kong | johnsom: thanks. maybe we have to talk to db for now | 23:17 |
| johnsom | Yeah, or do a local patch... | 23:18 |
| kong | johnsom: hah, yeah, will consider that | 23:18 |
| kong | our policy is upstream first :-) | 23:18 |
| johnsom | Good policy. | 23:18 |
| johnsom | The OpenStack stable branch policy says no backported features only bug fixes, so they sometimes conflict. Others just run master.... grin | 23:19 |
| kong | yeah, i know. need a lot of testing if we want to backport some feature to stable branch, unless it could bring much benifit to the business | 23:20 |
| johnsom | Queens Milestone 1 release comes out in a week or two if that helps you at all | 23:23 |
| kong | will evaluate it and discuss with ops | 23:24 |
