avishayvincent_hou: yes, couldn't make it unfortunately06:40
vincent_houThere are stuffs going on about migration.06:40
vincent_houThank you for your comments on the spec.06:40
vincent_houI replied with my comments back.06:41
vincent_houHope you can take a look. One important thing is that for all the issues related to in-use volume, we need to wait until multi attach lands in nova. Currently I am considering available volumes only.06:42
*** dims_ has quit IRC06:42
vincent_houthe original link is here: https://etherpad.openstack.org/p/volume-migration-improvement06:43
*** markus_z has joined #openstack-cinder06:43
vincent_houAbout the management of the volume status, we reach an solution in the session.06:43
avishayvincent_hou: what does in-use volumes have to do with multi-attach?06:44
vincent_houWe expect volume status tells the actual status of the volume, and we need to know if the last migration fails or succeeds.06:44
avishayvincent_hou: if you want to expose information to all users that was until now admin-only, then i think you'll need to open a security advisory on that06:45
avishayvincent_hou: i'm not sure that's what you want to do, and i think people are confusing 'user' and 'admin'06:45
vincent_houSure.06:45
vincent_houI will make the difference for them06:45
vincent_houThank you for pointing out.06:45
vincent_houHow nova instance will get the volume attached will be changed due to the feature of multi attach. We talked about the VM migration with volumes attached in the sessions. Everything needs to wait until the code merged in nova.06:47
*** zhenguo has joined #openstack-cinder06:54
vincent_houThat is why I would like to consider the issues regarding to the in-use(attached) volumes after the multiple attachment support is merged in nova.06:56
avishayvincent_hou: it should still be in the spec.  you can mention that work on in-use will start after multi-attach is merged.06:58
vincent_houAnyway, I will change it to make the scope more clear.06:58
avishayvincent_hou: ok, thanks!06:59
vincent_houI plan to draft another spec for the attached volume, because the attached volumes will introduce more issues.06:59
vincent_houBefore the summit, I was expecting to discuss the issues for attached volumes. However, since nova is on a change for the volume attachment, we said let' s wait for the multi attach to land.07:02

vincent_houI will limit the scope to admin only, not the volume users? Does it sound ok to you?08:10
*** lennyb has joined #openstack-cinder08:10
vincent_houbut I prefer to change the volume status to "migrating" during migration to avoid the confusion of available volume unable to attach, in-use volume unable to detach.08:12
vincent_houAnyway, I have to move it forward.08:15
avishayvincent_hou: i wrote that there is no reason to not allow attach/detach - you can abort the migration08:21
avishayvincent_hou: if you want this to be the first instance in the history of cinder to expose backend information to users, go ahead08:21
vincent_houHow to abort the migration if it being processed08:22
vincent_houAnd you have no idea what stage you are in a migration. What if the original volume is being deleted?08:23
*** ndipanov has joined #openstack-cinder08:24
vincent_houI just want to expose some information to the admin08:24
avishayif the original is deleted then you finish, otherwise you stop the copy and delete the source08:25
vincent_houAs i said, I omit the users08:25
avishayyou can expose whatever you want to the admin, the more the merrier08:25
avishayyou said you want to change the status, which everyone sees08:25
vincent_houOK.08:25
avishayif the core team wants to expose the information that's fine, but i just raised an objection08:26
vincent_houThe problem is that is there command i can run to stop the migration?08:26
avishayCinder manages the migration, need to add code to abort it08:27
vincent_houOK. This is something new to be added? Right?08:27
avishayYes08:28
*** pradipta has quit IRC08:29
vincent_houOK. Let's speak step by step. My brain can not go that fast.08:29
vincent_houThere is a case that the old volume is about to delete and the new volume is already there, but the migration is not complete. If user do attach, how to handle?08:30
vincent_houRoll back to origin? Or try to complete the migration?08:31
vincent_houIt is good idea to stop migration, but it is a bit tricky to control.08:32
avishayin my opinion if the copy finished, complete the operation, otherwise stop the copy and delete the destination08:32
avishayit's not easy, that's why i didn't do it as a first step, but it's necessary IMO08:32
avishayare you moving the code to taskflow?  i saw something about taskflow in the etherpad08:33
vincent_houWell, to be honest, for available volumes, it is ok to do this way. For attached volumes, I am still not quite sure.08:33
vincent_houTo be honest, there is great argument about taskflow in the summit.08:33
avishaythere is an argument about taskflow in every summit for the last 2 years :)08:34
vincent_houWithin 4 to 6 weeks, if there is no significant case using it. cinder is gonna abort it08:34
vincent_houThis is the exact quote.08:34
vincent_houI guess one week already passed.08:35
vincent_houWell, I think I can leave the status as it is, until I find out the better solution.08:37
nikeshmavisahy: hi08:42
nikeshmavishay: didnot see you in vancouver08:42

wanghaovincent_hou: hi~  I'm not sure whether to push new feature that using TaskFlow.  I want to do that, but people tell me it may be removed....08:48
vincent_houwanghao: I am a bit worried as well.08:48
vincent_houwanghao: Within 4 to 6 weeks, if there is no significant case using it. cinder is gonna abort it .08:49
vincent_houI have no idea how strong they can keep this promise.08:49
vincent_houWithout taskflow expert, I can do nothing with taskflow, even I want to.08:50
vincent_houI am not sure if it deserve my last try with reaching out taskflow guys.08:50
wanghaovincent_hou:  Yes, In fact, there is a bp in my hand that using it too,  but I'm sure if it is a  significant case using it.08:52
vincent_houWhat is it?08:52

wanghaoNot yet.08:58
vincent_houIf this can be merged, it is a proof .08:58
wanghaoYes, I think so.08:58
wanghaoDo we need taskflow folks to review those patch?08:59

hemnapatrickeast, it can't be done automatically18:30
hemnabecause it's up to the volume driver to decide what to do with mapping18:31
hemnaa driver might not want to export a volume to every possible combination18:31
hemnadue to a number of factors18:31
hemna1) multipath might be off/disabled18:31
hemna2) the backend array might have limitations wrt how many ports a volume can be exported, etc18:32

hemnait would be nice if every array was the same wrt to this, but not all are created equal18:33

mtaninohemna: sorry for my interrupt to your multi attach support patch. https://review.openstack.org/#/c/85856/18 I just updated few unit tests.18:46
hemnaam I the only one annoyed with c-vol startup puking out all the conf options, and in the middle of those options being dumped out we see volume manager log output intermixed ?18:46
hemnalooks like openstack/common/service.py is responsible for dumping the config options18:46
hemnain a separate thread, while the volume manager's init_host is being run.18:47
hemnableh18:47
hemnaguess we have no control over that18:48
e0nehemna: openstack/common/service.py is deprecated. it will be moved to oslo.service soon18:48

*** vilobhmm has joined #openstack-cinder18:49
hemnalooks like that has the same 'problem'18:49
hemnait just pukes out CONF.log_opt_values always18:50
hemnaIt would be nice to disable that there, and just have our Service.start() dump that prior to calling self.manager.init_host()18:50
hemnathen anything inside of init_host() will not get logged until after the CONF.log_opt_values finishes18:51
