aspierssamP_: I attended the PWG call last night10:58
aspierssamP_: I updated them on our last VoIP meeting regarding the 4 new user stories, and suggested that these should be submitted as separate user stories10:58
aspierssamP_: then they could be linked from the "Related User Stories" section of the HA VM user story10:59

samP_aspiers: hi11:15
samP_aspiers: Thanks for the comments, I wasnt able to attend the meeting, since it was too early in my zone.11:17
aspiersno problem11:17
aspiersI told the PWG that I thought these were very good and valid use cases11:17
samP_aspiers: I read your comment on user story11:17
aspiersbut I am worried that the HA VM user story is at risk of scope creep11:17
aspiersOK11:17
aspiersI'd prefer to keep the scope smaller, so we can finish it sooner :)11:17
aspierswell, that is not the main reason actually11:18
samP_yes I do understand11:18
aspiersI think the 4 new user stories have a wider scope than just HA11:18
aspiersand they might overlap with other user stories in OpenStack11:18
aspiersespecially in nova11:18
samP_I think we can link the user stories with more specific use cases  and core use case (which is now in review)11:20
aspiersyes11:20
samP_as you said, first we have to write them down11:20
aspiersI am currently editing the HA VM user story11:20
aspiersI will soon submit a lot of small reviews to improve it11:20
aspierseach change will be very small and simple to review (I hope)11:21
samP_great11:21
*** ushkalim has quit IRC11:23
samP_aspiers: are your 4 user stories going to connect with current use case? or totally different ones?11:26
aspiersthey are your 4 user stories :)11:27
aspiersnot mine11:27
samP_ah.. ok11:27
aspiershttps://review.openstack.org/#/c/31843111:27
*** jpena is now known as jpena|lunch11:27
samP_you mean 4 new user stories we added to current user story..11:28
aspiersyes11:28
aspiersthey are all good, but I don't think any of them are specific to HA VMs11:28
aspiersthey all have wider scope11:28
aspiersfor reasons I gave in the review11:28

samP_your comments make sense. However, I think Kazu's point is keep the requirements for VMHA in the user story. So, it they will satisfied by the final solution.11:37
aspierswhich requirements?11:38
samP_ requirements for make it operational11:38
aspiersright, but which ones exactly :)11:38
samP_I think his most concerns are Capacity Reservation and Failover management11:41
aspiersright, but capacity reservation is not limited to just HA VMs11:43
aspiersit applies in other scenarios too11:43
aspiersso it deserves its own user story11:43
aspiersand the HA VM feature can still be operational without automatic capacity reservation, e.g. via operators proactively monitoring capacity11:44
aspiersand taking manual action accordingly11:44

*** markvoelker has joined #openstack-ha12:02
aspierssamP_: I think each of these 4 usage scenarios could be converted into very nice independent user stories, with very little overlap on the existing HA VM user story. So I would definitely recommend you guys think about submitting those. That's what I said in the meeting last night, and noone could think of any problems with that approach.12:08
aspiersthey don't overlap with each other either12:08
aspiersso I think it could work really nicely12:08

samP_I think we have different view point about VMHA. For my understanding, if we try to define what is instance HA, then we must focus on simple user story as you mentioned above. But NTT point of view, we are looking for a product that can provide VMHA with all the operational features. It may be the one project or many. For a Ex: core VMHA done by the pacemaker and mistrial and all the monitoring and reservation part nee12:31
samP_d to be done with some other projects. In both cases, current missing features will go to different spec in each related projects. Or if there is no project can achieve the features, the we need a new project. So then, come to the original question, do we need to separate the user stories? I somewhat agree to your solution. But then, where is the grand design of VMHA exist?12:31
samP_I will discuss this with kazu12:32
samP_Really sorry, but I hv to go AFK for a meeting. I will be back12:33
