Yanyanhuyes, actually 1537685 was reported yesterday05:38

YanyanhuI manually set its status to in_progress this morning05:39

PennyLiuHi, everyone. I'm newbie to openstack senlin. I'm looking forward to work with you guys.08:29
YanyanhuPennyLiu, :)08:30
xuhaiweiPennyLiu, welcome08:32
xuhaiweisenlin gate seems not working now08:33
Qimingit is across the community08:33
Qimingpy27 and py34 gate are both unstable08:33
openstackgerritxu-haiwei proposed openstack/senlin: Update server metadata before updating node/cluster properties  https://review.openstack.org/27241608:38
Qimingpls avoid doing 'recheck' at the moment08:39
Qimingit will only aggravate the problem at the gate08:40
Qimingpeople are already on it, AJaeger and yolanda are debugging it, see #opentack-infra channel08:41

Qimingem, https://www.mirantis.com/blog/openstack-nfv-explained-openstack-foundation08:47
Qimingthis is an interesting report08:47
Qimingyou may want to check it, because 1) NFV is one of the largest groups of OpenStack users 2) it mentioned Senlin, ;)08:47
Yanyanhunice :)08:48
xuhaiweiyes, one of my boss also mentioned this, NFV and senlin08:49
xuhaiweibecause he likes NFV08:49
Qiminghow many bosses are you reporting to, ;)08:49
Qimingwe hope telcos like it too08:49
xuhaiweithe man who gives money to our team is our boss :)08:50
xuhaiweiI don't care who he is08:50
xuhaiweiby the way, my patch passed jenkins, it seems there is a rate of it08:51

Qimingxuhaiwei, generally looks good, but there is one thing08:55
Qimingposted comments08:56
xuhaiweisaw it, thanks08:57
Yanyanhuhi, xuhaiwei, in line 339 of https://review.openstack.org/#/c/272416/2/senlin/engine/node.py08:59
Yanyanhumaybe using exact match is better?09:00
Yanyanhuif self.cluster_id == ''09:00
Yanyanhulike this09:00
Qimingmaybe just 'if not self.cluster_id'09:00
*** junxu has quit IRC09:01
Yanyanhujust tried to make the code exact match the logic we defined for orphan node09:01
xuhaiweiI think Yanyan's idea is good09:02
Yanyanhualthough both ways will work :)09:02
xuhaiweican avoid the case when cluster_id is 'None'09:02

Qimingno, Yanyanhu09:38
Qimingyou are on the wrong patchset09:38

Qiminglixinhui, can we just show the manual one with a health monitoring done by consul?14:00
Qimingstill there?14:00
lixinhui_Qiming, DR == Data Recover?14:01
Qimingthen we propose the idea of (semi-)auto14:01
Qiminghopefully we can get some feedbacks14:02
Qimingor even better, we can have a semi-auto POC14:02
Qimingdisaster recovery14:02
lixinhui_I think we can14:02
Qimingit is more about storage than compute itself14:02
cschulzNo DR == Disaster Recovery14:03
lixinhui_okay, cschulz14:03
Qimingthe most useful scenario I can think of:14:04
Qimingdeploy a kolla cluster containing some openstack controller service14:04
Qimingthat means a container cluster already14:04
Qimingthen we monitor the service's availability using an external software14:05
Qimingtriggers auto-recovery when failures are detected14:05
Qimingthat will be solving a lot of problems people met when using pacemaker-corosync for openstack HA14:05
Qimingbut I'm not so optimistic we can get there by the summit14:06
cschulzI think it would be good to have a discussion with a HA and a DR expert.  So we don't paint ourselves into a corner by not considering important aspects.14:07
Qiminghaha, :) definitely14:07
*** yanyanhu has quit IRC14:08
lixinhui_I can do the development14:08
Qimingcschulz, I talked to Marcio Silva during my visit to Waston last November14:08
lixinhui_depend on your guys to define the scenarios14:08
cschulzYes, I know Marcio.14:08
Qimingthis is actually his preferred way of deploying OpenStack HA14:08
Qiminghe hates pcs -- the command line you will use to manage pacemaker HA clusters14:09
cschulzI will make a pass by Marcio14:09
Qimingthat would be cool14:10
cschulzAlso my buddy Rick Harper who is a DR expert.14:10
lixinhui_I do know if anyone care about health_management to load balancer pool14:11
lixinhui_I do not know14:11
lixinhui_or, there already some implements to it14:11
cschulzI'm also unaware of issues there.14:12
Qiminglixinhui_, I can find you some references14:12
Qimingit is about server failure detection using the loadbalancer14:12
lixinhui_thanks, Qiming14:12
Qiminga loadbalancer has a builtin healtmonitor component, which will monitor whether your node is still processing requests14:13
Qimingit will report a node failure when something bad is detected14:13
lixinhui_good, I wanna the report part14:13
lixinhui_I am trying to catch the error report14:14
Qimingthat failure detection is much more realistic than simple pings or queries to nova14:14
cschulzIf it also reports average response times, it can be part of an autoscaling solution.14:14
lixinhui_I can learn to integrate them together14:14
Qimingexactly, we prototyped such a solution in a customer engagement14:14
cschulzYes, and the customer thought it was cool also.14:15
lixinhui_I am sure our customer will like it also14:15
Qiminghow about we propose that as a summit topic14:16
Qimingand get it done by March?14:16
QimingI think we have all the technology pieces14:16
lixinhui_I think we can with help from your guidance14:16
Qimingjust need to integrate them into a solution14:16
cschulzYes that would be cool.14:17
Qimingokay, let's jump onto it then14:17
lixinhui_Okay, send me the references and I will try it quickly14:21
