| gouthamr | bswartz: :P sorry | 00:52 |
|---|---|---|
| bswartz | it's fine the cinder guys use our channel too sometimes | 00:53 |
| gouthamr | bswartz: nova-net-id is taken in at the API | 00:53 |
| gouthamr | bswartz: i saw your email about removing the plugin | 00:53 |
| bswartz | right that will go away | 00:53 |
| gouthamr | bswartz: no microversion? :) | 00:53 |
| bswartz | well in reality changing the API might not be worth it | 00:54 |
| bswartz | we have to think carefully about what to do with that field, but if we leave it in it will be ignored | 00:54 |
| bswartz | even if we microversion the removal of it, older microversions will still ignore it | 00:54 |
| gouthamr | bswartz: wish we started throwing a deprecation warning for the field.. | 00:55 |
| bswartz | the 2 best options are probably to leave it in and just ignore it from newton on, or to remove it and apologize for the API break | 00:55 |
| bswartz | the fact is that that field always depended on nova-net existing -- users HAVE to know that it won't work without nova net being present | 00:56 |
| bswartz | if anyone was surprised by its removal they'd have to be clueless | 00:56 |
| gouthamr | yes, we can document the breakage | 00:56 |
| bswartz | anyways I'm going to be in my garage debugging my breaker panel | 00:57 |
| bswartz | be back later | 00:57 |
| gouthamr | np! i got my answer.. | 00:57 |
| gouthamr | thank you | 00:57 |

| bswartz | tbarron: ping | 18:24 |
| bswartz | tbarron: are you still working on address quota bugs in Manila? | 18:25 |
| tbarron | bswartz: pong | 18:25 |
| tbarron | well, i'd like to get back to it :-) | 18:26 |
| tbarron | bswartz: do you have one in hand that needs attention? | 18:26 |
| bswartz | tbarron: we realized recently that manage snapshot does something strange | 18:27 |
| bswartz | xyang1: ^ | 18:27 |
| bswartz | there is logic in the manager which updates the quota based on what the driver says the size of the snapshot is | 18:27 |
| tbarron | bswartz: mostly i've been following the debate upstream between those who want to keep reservations and those who want to do away with them in favor of resource claims, and thinking about implications | 18:27 |
| bswartz | I would have assumed that the quota logic would be in the API layer and the manager wouldn't touch it | 18:28 |
| tbarron | therfe is some funniness in cinder with manage-* iirc | 18:28 |
| tbarron | lots of times currently the reservation is made in the api and then committed or rolled back in the volume/share service | 18:29 |
| tbarron | imo a likely source of races and bugs | 18:29 |
| bswartz | yeah... | 18:29 |
| tbarron | bswartz: xyang1: anyways, is there a bugo for the one you are talking about? | 18:32 |
| tbarron | i will assign it to myself | 18:32 |
| xyang1 | bswartz: I am not aware of it yet | 18:32 |
| tbarron | while i'm learning manila it makes more sense for me to take bugs than to try to add more creeping^w features | 18:33 |
| bswartz | no I just noticed it looking at cknight's manage snapshot code | 18:33 |
| bswartz | I thought it was strange that the driver is returning a size at all | 18:34 |
| tbarron | ok, seems like lots of issues get noticed w/o bugs filed :) | 18:34 |
| xyang1 | bswartz: doesn't it behave the same with manage share? I most likely copied from there | 18:34 |
| tbarron | xyang1: that would be my guess too | 18:34 |
| bswartz | well it's not a bug until someting goes wrong | 18:34 |
| tbarron | manage-volume looks weird to me in cinder | 18:34 |
| tbarron | w.r.t quotas | 18:34 |
| *** merooney has joined #openstack-manila | 18:35 | |
| bswartz | it feels like what we have is a *potential* for a bug if a vendor adds incorrect logic to their driver | 18:35 |
| xyang1 | tbarron: ya, quota is broken | 18:35 |
| tbarron | xyang1: you are talking hemna-speak with that "ya" | 18:35 |
| xyang1 | tbarron: it does not even look at what is really created and update quota in api | 18:36 |
| xyang1 | tbarron: oh, I am influenced by him, maybe:) | 18:36 |
| tbarron | bswartz: xyang1: so at this point I am going to just add this convo to my list of quota issues | 18:36 |
| tbarron | bswartz: xyang1: but I don't yet have anything concrete and actionable | 18:36 |
| tbarron | bswartz: xyang1: i may file some bugs from code-inspection alone if that turns out to make sense. | 18:37 |
| xyang1 | tbarron: are you going to tie your work with the cross project quota thing? | 18:37 |
| tbarron | like build a candidate test and prove it | 18:37 |
| *** merooney_ has quit IRC | 18:37 | |
| bswartz | I wouldn't be upset if your proposed rewriting the whole quota system | 18:37 |
| tbarron | xyang1: i am following the cross-project thing but it would be a mistake to wait for it to save us | 18:38 |
| xyang1 | bswartz: +1 | 18:38 |
| tbarron | xyang1: bswartz: well i want to replace the govt too, the question is with what :-) | 18:38 |
| tbarron | xyang1: bswartz: so i'm more in study mode, but that doesn't preclude targeted short-term fixes when they are needed | 18:39 |
| tbarron | bandaids | 18:39 |
| xyang1 | tbarron: I will be interested too see if you can look at what is really created before updating quota in db | 18:39 |
| xyang1 | tbarron: or at least update it after the creation:) | 18:40 |
| tbarron | xyang1: interestingly, jay pipes is pushing a contrary approach: do pessimistic claims instead of reservations, immediately in the api, using compare and swap to either get a claim on the resource or fail fast | 18:41 |
| tbarron | the idea is to eliminate the race window until actual reservation commit or failover | 18:41 |
| tbarron | and to get the quota system out of doing cached resource usage | 18:42 |
| tbarron | xyang1: I'm not saying that's the right way to go, but it's an interesting take on the issue. | 18:42 |
| tbarron | o/w I think you are exactly right, we've got to do lots of work looking at whether we actually succeeded or not after we took a reservation. | 18:43 |
| bswartz | tbarron: how do you avoid caching the usage? | 18:43 |
| xyang1 | tbarron: where if api knows what driver can do, that is fine, but it updates quota before the request is sent to scheduler | 18:43 |
| tbarron | that's being done in inconsistent ways today | 18:43 |
| tbarron | and rollbacks are not done when they should be | 18:43 |
| tbarron | and there are races so fixing quotas becomes entwined and dependent on solutions to distributed service concurrency | 18:44 |
| xyang1 | tbarron: when do they have quota meetings? | 18:44 |
| tbarron | bbiam | 18:44 |
| tbarron | bswartz: i'm not in a position to defend at this point, but as i understand it the idea is to do an actual claim - not a reservation that has a time period and expiration - at the time that you do the initial DB create of the resource in the api | 18:47 |
| tbarron | that claim checks against actual usage of the resource | 18:47 |
| bswartz | okay so there would still be a row in a table with a number that represents the sum total of all of your shares/volumes/snapshots/etc | 18:47 |
| tbarron | not against tables that the quota system maintains of what it believes is used plus what it has granted reservations for | 18:47 |
| bswartz | yeah I agree reservations are funky -- just increment the number | 18:48 |
| tbarron | the table would be, say, shares table rather than quota usage tables | 18:48 |
| tbarron | xyang1: meetings of the delimiter group are Tuesdays at 1:00 EST in #cpenstack-meeting-cp | 18:49 |
| tbarron | xyang1: but so far as i an tell much of the "action" on the issues i mention has been side-bar | 18:49 |
| tbarron | i believe jay is writing a spec, maybe for nova quotas ? with these ideas. | 18:49 |
