* rosmaita blushes14:06
jungleboyjrosmaita:  Are there many patches waiting on approval?14:06
jungleboyj:-)14:07
rosmaitai don't think so, but i got distracted this morning and didn't look14:07

rosmaita#topic initial import of  devstack-plugin-open-cas14:08
*** openstack changes topic to "initial import of  devstack-plugin-open-cas (Meeting topic: cinder)"14:08
rosmaitaLiangFang has been busy!14:08
rosmaita#link https://review.opendev.org/#/c/713173/14:08
LiangFanghi14:08
LiangFangI have prepared the initial14:08
LiangFangand I think I need to add tempest job14:09
LiangFangI take a look of devstack-plugin-ceph14:09
LiangFangseems I need to add tempest test cases in cinder-tempest-plugin14:10
*** eharney has joined #openstack-meeting-414:10
LiangFangand then TEMPEST_PLUGINS: '/opt/stack/cinder-tempest-plugin'14:10
rosmaitayou mean in .zuul.yaml ?14:11
LiangFangyes14:11
LiangFangnot sure i'm correct or not14:11
rosmaitai'm not sure either14:12
LiangFangi will try to test this way14:12
rosmaitabut we don' t need to wait until we figure it out to get the repo merged14:12
rosmaitayou have some basic tests there of the plugin itself14:12
smcginnisI haven't had a chance to actually stack with that plugin. I'm assuming you have and it all works LiangFang?14:12
LiangFangyes, i use github repo14:13
LiangFangand it can work when ./stach.sh14:13
LiangFangit installed and uninstall open-cas normally14:13
smcginnisPerfect, thanks.14:14
LiangFanggithub repo is same with this repo in code14:14
rosmaitagreat, that's a good start14:14
LiangFangnext, I need to add tempest test14:15
smcginnisI think the tempest test can be a follow up. Just my opinion. Might be good to get the code in place so the repo is there, then enhance it with better testing.14:15
LiangFangbut I think i can add in next patch14:15
LiangFangsmcginnis: agreed, thanks14:16
e0nesmcginnis: +114:16
rosmaitai agree with smcginnis, will be good to have this in place and then we can work with it14:16
LiangFang+114:16
rosmaitaplus, i think it can't actually break anything at this point14:16
rosmaita:)14:16
LiangFangno code referenced to this repo correctly I think14:17
rosmaitaright, that will be the next step14:18
rosmaitathanks, LiangFang ... anything else?14:18
LiangFangwhen I do test, I just add in local.conf14:18
LiangFangenable_plugin devstack-plugin-open-cas https://...14:18
rosmaitayes, i think that's the standard way to enable a plugin14:19
LiangFangsorry I have not attend the virtual PTG meeting because my daught got fever14:19
rosmaitahope she's OK14:19
rosmaitamy daughter also woke up with a fever this morning :(14:20
LiangFangyes, she's OK now, thanks. that's all from me14:20
jungleboyjrosmaita:  ++14:20
rosmaitaok, great14:20
jungleboyjrosmaita:  Hope your daughter is ok.14:20
rosmaitayeah, just  a low-grade fever at this point, so normally noting to worry about14:20

rosmaita#topic os-reset_status notifications not going to the standard publisher14:21
*** openstack changes topic to "os-reset_status notifications not going to the standard publisher (Meeting topic: cinder)"14:21
rosmaita#link https://review.opendev.org/#/c/708563/14:21
rosmaitahemna has ^^ up14:21
rosmaitait looks ok to me14:21
rosmaitabut i just wanted to ask whether anyone knows of a reason why those notifications weren't going to the standard queues for cinder?14:22
eharneydo we have any general documentation on how these notifications work?14:22
smcginnis^14:22
smcginnisI think we've had issues from time to time with notifications because not many people even are aware of them.14:22
eharneyit wasn't really obvious to me why, for instance, snapshot notifications should go to a different publisher than volumes14:23
rosmaitai couldn't find anything14:24
toskyit's a repository14:24
toskyoh, sorry, ignore me14:24
rosmaitatosky: was waiting for you to elaborate14:25
rosmaita:)14:25
rosmaitaso yeah, i don't have an answer to eric's question14:25
rosmaitai guess the thing to do now is to make these consistent with the others14:26
smcginnisWell, we can use git blame to find the commits that added the notifications. I'm guessing will just find that whoever added them just didn't know how things are supposed to work.14:26
smcginnisThe tricky part will be that now there may be some consumers looking for these notifications in different places.14:26
smcginnisSo I guess if we change any of them, we need to at least be very clear in the release notes about it.14:26
rosmaitasorry, was just looking at that patch14:28
rosmaitayes, i agree about the release note being beefed up a bit14:28
rosmaitai guess we could also send an email to [ops] requesting comments14:29
smcginnisNot a bad idea.14:29
rosmaitai'll do that14:29
jungleboyjYeah, I am having trouble following the release note.  Trying to suggest improvement there now.14:29
rosmaita#action rosmaita email to [operators] about change to publishing queue for os-reset_status notifications14:30
rosmaitaok, thanks ... if anyone has second thoughts or sudden recollections, please comment on the patch14:30
rosmaitathis next topic is exciting14:31
rosmaita#topic new job to test Active/Active HA14:31
*** openstack changes topic to "new job to test Active/Active HA (Meeting topic: cinder)"14:31
rosmaitae0ne: that's you14:31
e0ne:)14:31
jungleboyjThat is exciting.14:31
e0neto be clear, I'm not proposing adding any new tests now :)14:31
e0neeverything I propose is to add a regular tempest tests with cinder plugin14:32
e0neso it will find such bugs as https://bugs.launchpad.net/cinder/+bug/186790614:32
e0ne#link https://bugs.launchpad.net/cinder/+bug/186790614:32
openstackLaunchpad bug 1867906 in Cinder "group-create-from-src doesn't work in active/active mode" [Undecided,In progress] - Assigned to Ivan Kolodyazhny (e0ne)14:32
jungleboyjAh, sounds like a good idea.14:33
e0neI know that geguileo was going to create some active/active-specific test framework.. it's also great idea14:33
geguileoe0ne: yeah, that's on hold and I don't expect to be able to work on that for a while... :-(14:34
e0nebut with a limited capacity I would like to have tempest run to be sure that A/A doesn't break anything14:34
e0negeguileo: :(14:34
smcginnisAny additional testing would definitely be an improvement.14:34
smcginnisI'm still concerned that we have this feature in there with no real way of knowing it works right.14:35
smcginnisOther than that geguileo has run some things locally. :)14:35
e0nesmcginnis: +114:35
e0nesmcginnis: we're going to use it in our distro14:35
eharneyas are we14:36
smcginnisWe'll probably know for sure soon enough then. :D14:36
e0ne:)14:36
jungleboyjWe use eharney 's distro, so ...  :-)14:36
rosmaitathis sounds like a good start14:36
jungleboyjTesting in production is the best!14:37
jungleboyjAdds spice to life.14:37
geguileorofl14:37
e0nejungleboyj: does it mean Lenovo will support  HA soon?14:37
rosmaitawell, it certainly adds urgency14:37
jungleboyjgeguileo:  Thought you could use a laugh.14:37
jungleboyje0ne:  The Lenovo driver?14:37
geguileojungleboyj: I do, thanks  :-)14:38
e0neyep14:38
e0nelooks like we agree with my proposal... so I have one more question about our CI...14:38
jungleboyje0ne:  No, I don't think we will use it there but we are making use of the Ceph driver which has HA support.  Right?14:38
e0nejungleboyj: fair enough14:39
e0nedoes anybody remember where is our multinode job?14:39
jungleboyjWe will also be using NetApp's drivers.  I think they may have added support.14:39
sfernandwe have a patch enabling AA only for SF until now14:40
sfernandyou are saying for ONTAP right?14:41
jungleboyjYes, ONTAP.14:42
rosmaitae0ne: i think the grenade jobs are multinode ?14:42
e0nerosmaita: I'm not sure14:42
rosmaitame neither, tbh14:42
lsekijungleboyj: we don't have plans to implement A/A on ONTAP yet14:42
e0newe've got lvm multibackend14:42
e0nebut I don't see any multinode job now :(14:43
jungleboyjlseki:  Ok.  Good to know.14:43
e0neI remember we'd got it in the past14:43
rosmaitatosky: are you around?14:43
lsekijungleboyj: but it's in progress for solidfire14:43
rosmaita(Luigi is my go-to person for gate jobs)14:43
e0ne:)14:44
toskyrosmaita: yes14:44
eharneythe "mn" in "cinder-grenade-dsvm-mn-sub-volbak" implies it does something multi-node but i'm not sure what14:44
toskyyes, it uses two nodes (and split the cinder services)14:45
rosmaitatosky: maybe you can coordinate with e0ne -- he has some ideas for adding some tests, but needs a multinode job14:45
toskywell, the grenade job is not the first choice as it is for upgrades, you probably want a normal multinode job14:45
whoami-rajatthe cinder-grenade-dsvm-mn-sub-volbak and one more job with -volsch in the experimental job were defined for multinode testing purpose14:45
e0neit14:46
toskyall the tempest-based jobs are potentially multinode, you just need to change the nodeset14:46
e0neit's good that at lease grenade is multinode14:46
toskywhich kind of tests do you want to add?14:46
e0netosky: sounds good. I'll try to add a new job14:46
rosmaitatosky: do you know any examples of a "normal" (non-grenade) multinode job?14:47
e0netosky: some A/A HA configuration14:47
rosmaitai think e0ne just wants to get an A/A setup, and then run our normal tempest tests and see what breaks14:47
e0nerosmaita: thanks. it's exactly what I want to do14:48
toskyrosmaita: tempest-multinode-full from tempest.git14:48
toskyit's basically devstack-tempest with a different nodeset14:48
rosmaitatosky: sounds like what we need14:49
e0ne+114:49
smcginnisDifferent nodeset, then some config changes to set up the A/A bit.14:49
rosmaitae0ne: see if you can get something started, and ask for help if you need it next week14:49
rosmaitai think there's a lot of interest in getting something like this working14:50
e0nerosmaita: ok, will do it asap14:50
rosmaitagreat14:50
rosmaitaso that actually was an exciting topic!14:51

smcginnisrosmaita: Anything we need to do to start planning for the virtual PTG?14:52
rosmaitai was going to wait until M-314:52
jungleboyj:-)14:52
rosmaitasmcginnis: is it virtual for sure?14:52
jungleboyjHas it been officialy decided virtual?14:52
jungleboyjJinx.14:53
smcginnisI thought so.14:53
e0nejungleboyj: afaik, not yet14:53
rosmaitathe foundation page hasn't been updated since 2 march14:53
* smcginnis looks again14:53
rosmaitahttps://www.openstack.org/events/covid-19-coronavirus-disease-updates14:53
jungleboyjI think it is a safe bet that it will be.14:53
e0nehttps://www.openstack.org/events/covid-19-coronavirus-disease-updates14:53
jungleboyjUnfortunately.14:54
toskythe European Football Championship has been postponed to 2021 (and it was supposed to happen in June), I would be surprised if the PTG was going to happen14:54
e0nejungleboyj: +114:54
smcginnisIt's probably safe to assume APril will be virtual.14:54
whoami-rajati think the KubeCon was postponded as well14:54
jungleboyjMay will probably be all virtual as well.14:55
rosmaitai guess the only worry will be everyone using bluejeans at once may crash it!14:55
jungleboyjThey were talking about this going through the Summer in the US potentially but I really hope not.14:55
rosmaitamy thought would be, we'll hold the virtual PTG on the dates already reserved14:55
smcginnisI've found this useful: https://stayinghome.club/14:55
*** macz_ has joined #openstack-meeting-414:55
rosmaitai guess the only problem will be time zones14:55
jungleboyj:-)  This is an amazing scaling test for VPN providers, streaming companies and video conferencing platforms.14:56
smcginnisI've been impressed how little issues I've noticed so far.14:56
toskyrosmaita: maybe  the foundation could provide a private jitsi instance on private server for the PTG14:56
rosmaitai think we can do multiple 2 hour slots such that at least one slot is convenient for each TZ14:56
smcginnisWe do have our own asterisk server. Not sure how much that scales.14:56
jungleboyjsmcginnis:  ++  My internet is a little slower, but not bad.  Apparently some people in Lenovo were having VPN issues.  Not too bad though.14:57
rosmaitatosky: i misread that as "private jet" and thought, "but where would we go?"14:57
smcginnis:)14:57
jungleboyjRachel is having major issues with her VPN.14:57
rosmaitaok, i guess the summary of that is we should start thinking about a virtual PTG14:57
jungleboyj:-)14:58
rosmaitaok, just about out of time14:59
rosmaitawe'll start planning at next meeting, i guess14:59
rosmaitaanyone have anything to say?14:59
