I've checked openstack-ra repository. 09:09:13 rkmrHonjo: let me know if I can help 09:10:09 aspiers: Thanks a lot! I'll ask to you if I have any questions. 09:10:10 rkmrHonjo: do you know which bit you want to work on first? 09:10:37 aspiers: can you share the link for latest link for modular architecture? 09:11:32 #link https://aspiers.github.io/openstack-day-israel-2017-compute-ha/#/modular 09:11:45 aspiers: thanks. 09:11:53 press Space to go through the slides 09:12:00 thanks... 09:12:53 rkmrHonjo: are you going to Denver PTG? 09:12:54 OK, I read it after that. 09:13:22 aspiers: Sorry, I won't participate. 09:14:04 aspiers: Which part would you think is best to start? Host monitor? 09:14:26 aspiers: Are you already working on some of those? 09:15:18 samP: yes I think host monitor is probably best 09:21:27 aspiers: OK then, me and rkmrHonjo can start creating PoC on Host monitoring part. 09:21:27 I haven't had a chance to do anything significant on it yet, since we are busy with the HPE merger :-/ 09:21:27 aspiers: NP 09:21:27 samP: I guess the first step is to update the spec 09:21:27 aspiers: sure 09:21:27 https://github.com/openstack/openstack-resource-agents-specs/blob/master/specs/newton/approved/newton-instance-ha-host-recovery.rst 09:21:27 it would describe https://aspiers.github.io/openstack-day-israel-2017-compute-ha/#/nova-host-alerter 09:21:27 aspiers: spec for "nova-host-alerter" will be in instance-ha-host-recovery spec? 09:21:27 aspiers: or will it be a separate spec for modular architecture? 09:21:27 well, technically we also need a instance-ha-host-monitoring spec 09:21:27 since nova-host-alerter is in the top half of the diagram (monitoring) not the bottom (recovery) 09:21:27 aspiers: agree 09:21:34 see https://etherpad.openstack.org/p/newton-instance-ha line 119 09:21:39 line 124 is out of date now 09:21:50 samP, aspiers: OK. I start to design host monitor at first. 09:21:50 Should I design RA monitor with moduler architecture now? or, without it until completing implementation? 09:21:51 previously we thought that Pacemaker would do all the monitoring 09:22:22 rkmrHonjo: I think we should finish the two host monitoring/recovery specs first, to make sure we all agree on the design 09:23:17 aspires: OK. 09:23:23 so the monitoring part is pacemaker + pacemaker_remote + fence_compute + nova-host-alerter 09:23:38 aspiers: agree 09:23:45 great 09:24:32 aspiers: however, "nova-host-alerter" or something like that would be common for all the monitors? 09:25:39 you mean for VM monitoring/recovery? 09:25:47 aspiers: yes 09:26:00 maybe eventually, but I think it is good enough to stick with masakari-vmmonitor for now 09:26:17 aspiers: ok 09:26:24 if there are other VM recovery services in the future, we could extend masakari-vmmonitor to talk to them 09:28:20 I guess there's no advantage to generalising VM monitoring while there is only one option :) 09:28:32 aspiers: got it.. 09:29:21 aspiers: let's update the spec first. Once things get fixed in the spec, rkmrHonjo and me can start the PoC for this. 09:30:33 sounds perfect, thanks a lot! 09:32:04 aspiers: will you be able to update the spec? or should I start working on that? 09:34:09 samP: there's already https://review.openstack.org/#/c/406659/ 09:34:33 it is not merged yet, so we can update to include nova-host-alerter 09:35:04 which is what ddeja's final comment suggested, anyway :) 09:35:17 aspiers: yep 09:36:24 I will update that 09:36:51 aspiers: great..thanks 09:36:58 and we also need to update https://github.com/openstack/openstack-resource-agents-specs/blob/master/specs/newton/approved/newton-instance-ha-host-recovery.rst 09:37:11 aspiers: thank you... 09:37:27 rkmrHonjo: thank you for joining :) 09:39:31 aspiers: You're welcome. 09:41:09 aspiers: OK, if ddeja wouldn't mind, I can take over this.. 09:41:10 samP: ok I guess we're done, unless you have anything else today? 09:41:21 samP: I'm sure ddeja wouldn't mind 09:41:35 aspiers: ok then I will fix that 09:41:39 great, thanks! 09:41:54 alright. I will work on the monitoring spec ASAP 09:41:55 aspiers: session proposed for Ops Meetup in MEX 09:42:02 oh nice! 09:42:03 #link https://etherpad.openstack.org/p/MEX-ops-meetup 09:42:13 #action aspiers to update https://review.openstack.org/#/c/406659/ to latest architecture 09:42:22 #action samP to update https://github.com/openstack/openstack-resource-agents-specs/blob/master/specs/newton/approved/newton-instance-ha-host-recovery.rst to latest architecture 09:42:25 I will update you about ops meetup 09:42:28 great 09:42:39 my manager is finding out whether I can go to Denver 09:42:47 will you be there? 09:42:55 aspiers: yes, I will be there.. 09:42:59 cool 09:43:07 fingers crossed I can go :) 09:43:39 Sorry, my network is unstable today. 09:43:49 rkmrHonjo__: np 09:43:59 aspiers: ok then, nothing else from my side 09:44:04 rkmrHonjo__: http://eavesdrop.openstack.org/meetings/ha/2017/ha.2017-07-26-09.05.log.txt 09:44:21 aspiers: I will update you on ML about ops and other topics 09:44:27 perfect 09:44:39 ok, so we can close the meeting - thanks a lot both, and see you on #openstack-ha! 09:44:49 aspiers: thank you.. 09:44:55 rkmrHonjo__: thank you 09:45:04 #endmeeting
