| vponomaryov | tommylikehu: hello, you were looking for me? | 12:13 |
| vponomaryov | arnewiebalck: a bit more than completely different )) | 12:13 |
| zhongjun_ | vponomaryov: hi vponomaryov | 12:13 |
| vponomaryov | zhongjun_: hello | 12:14 |
| tommylikehu | vponomaryov: yes *we* are looking for you | 12:14 |
| vponomaryov | arnewiebalck: or you like Cinder's approach? | 12:14 |
| arnewiebalck | vponomaryov: yes … what do you have in mind specifically? | 12:14 |
| zhongjun_ | vponomaryov: I talked with gouthamr about :Support retrieve shares filtered by export-location | 12:14 |
| zhongjun_ | vponomaryov: How about we just open bug to implemet, and we don't need a spec | 12:15 |
| vponomaryov | arnewiebalck: cinder implements type quotas as new resources, in our case it will be same resources with more than one value - for share types and projects+users | 12:15 |
| vponomaryov | arnewiebalck: it is possible to do it considering presence of microversions | 12:16 |
| vponomaryov | zhongjun_: why it is bug? | 12:16 |
| vponomaryov | zhongjun_: and why do you need to have it as filter? | 12:16 |
| *** chlong has joined #openstack-manila | 12:16 | |
| arnewiebalck | member:vponomaryov: how would that approach affect the potential fixing of quota classes later on? | 12:16 |
| arnewiebalck | vponomaryov: how would that approach affect the potential fixing of quota classes later on? | 12:17 |
| vponomaryov | arnewiebalck: you need quota classes fixed anyway? | 12:17 |
| zhongjun_ | vponomaryov: because we already have filter for share, just no support export location filter | 12:17 |
| zhongjun_ | s/no/not | 12:17 |
| vponomaryov | zhongjun_: use case? | 12:17 |
| zhongjun_ | When user have a share that it has been mounted in VM, and user only know the share export location path. User often wants to quickly filter a share by share export location in Manila. | 12:18 |
| vponomaryov | arnewiebalck: if yes, then it should be done prior to implementation of per-share-type quotas | 12:18 |
| arnewiebalck | vponomaryov: well … operationally, it is very convenient to specfiy the initial quota for resources (rather than explicitly setting them) | 12:19 |
| vponomaryov | arnewiebalck: we have default quota value options | 12:20 |
| arnewiebalck | vponomaryov: also, if that approach would block quota classes for all times, we should probably not base the decision on whether or not I need them | 12:20 |
| zhongjun_ | vponomaryov:use case: When user has a share that it has been mounted in VM, and user only knows the share export location path. User often wants to quickly filter a share by share export location in Manila. | 12:20 |

| vponomaryov | zhongjun_: not sure about spec | 12:22 |
| zhongjun_ | vponomaryov: but we have less people contributing during pike. I think we could just add export location filter in share list. ok? | 12:23 |

| vponomaryov | arnewiebalck: so, in cinder you use only one quota class? | 12:30 |

| arnewiebalck | vponomaryov: yes | 12:30 |

| vponomaryov | arnewiebalck: returning to question of cinder-alikeness | 12:31 |
| vponomaryov | arnewiebalck: does it matter for you to have as much similar API as possible or not? | 12:32 |
| arnewiebalck | vponomaryov: no | 12:32 |
| vponomaryov | arnewiebalck: just some to satisfy use case? | 12:32 |
| arnewiebalck | vponomaryov: yes, that’s fine for me … but how about consitency across projects? or is that not a concern? | 12:33 |
| arnewiebalck | s/consitency/consistency/ | 12:33 |
| vponomaryov | arnewiebalck: cinder's approach is easy-way for developer | 12:34 |
| vponomaryov | arnewiebalck: and solves use case | 12:34 |
| vponomaryov | arnewiebalck: but it is not good from architecture point of view | 12:34 |
| arnewiebalck | vponomaryov: ok, as mentioned, I’m perfectly fine with doing things differently | 12:35 |
| vponomaryov | arnewiebalck: so, it is question, whether to implement it correctly or do it in consistent way | 12:35 |

| tbarron | vponomaryov: no, i would ordinarily care about consistency too | 13:23 |
| tbarron | vponomaryov: BUT probably cinder and manila will rework quotas in a few releases if | 13:23 |
| tbarron | vponomaryov: the current initiative to put limits in keystone for hierarchy succeeds | 13:23 |
| vponomaryov | tbarron: only if some common quota service appears | 13:24 |
| tbarron | vponomaryov: it seems to have legs | 13:24 |
| vponomaryov | for example | 13:24 |
| tbarron | vponomaryov: keystone would just have limit info (for hierarchy, so per-user quotas wouldn't be needed). | 13:24 |
| tbarron | vponomaryov: but enforcement of quotas would still be in manila, in cinder, etc. | 13:25 |
| tbarron | vponomaryov: the other area to consider is when we get OSC integration | 13:25 |
| vponomaryov | tbarron: how many different share/volume types you have seen in production deployments? | 13:25 |
| *** tommylikehu_ has quit IRC | 13:25 | |
| tbarron | vponomaryov: but it's not as if I think cinder has it perfect right now, so I don't think we really know how to conform/be-consistent anyways | 13:26 |
| tbarron | vponomaryov: not all that many myself | 13:26 |
| tbarron | tens maybe | 13:26 |
| vponomaryov | one per real storage or 1 to many? | 13:26 |
| vponomaryov | and if the latter, why so? | 13:27 |
| arnewiebalck | vponomaryov: we have currently 7 volume types (on 4 independent backends) | 13:27 |
| vponomaryov | arnewiebalck: why do you need 7 for 4? | 13:28 |
| tbarron | arnewiebalck: are four of these just mapping to the backends? | 13:28 |
| arnewiebalck | vponomaryov: b/c we have different QoS types on the same backend | 13:28 |
| arnewiebalck | vponomaryov: like a standard and a high-IOPS type | 13:28 |
| vponomaryov | arnewiebalck: and do they have different quotas? | 13:29 |
| arnewiebalck | vponomaryov: yes, they have different quotas | 13:29 |
| tbarron | also, one can have additional types that span multiple backends but have e.g. just ssd disk | 13:29 |
| arnewiebalck | vponomaryov: IOPS is a precious resource | 13:29 |
| tbarron | or just replicated storage (but multiple backends possible) | 13:30 |
| vponomaryov | arnewiebalck: do your use case require quota for share type + project or just general share-type quota is enough? | 13:30 |
| vponomaryov | arnewiebalck: like, global quota and smaller quotas for different projects | 13:30 |
| vponomaryov | arnewiebalck: global means "backend cannot handle more" | 13:31 |
| arnewiebalck | tbarron: agreed, we don’t use that, though | 13:31 |
| tbarron | arnewiebalck: vponomaryov I have seen those cases too though | 13:31 |
| arnewiebalck | vponomaryov: per type and project | 13:31 |
| vponomaryov | arnewiebalck: only so? no need in global? | 13:32 |
| arnewiebalck | vponomaryov: I don’t think we have a global quota | 13:32 |
| tbarron | vponomaryov: I think there is the use case in general of serfs and noblemen get different quotas even though even the serfs can use a little bit of the gold share type | 13:32 |
| arnewiebalck | vponomaryov: we try to keep track of things | 13:32 |
| arnewiebalck | vponomaryov: and monitor the fill status | 13:33 |
| vponomaryov | arnewiebalck: understood, no real value then | 13:33 |
| vponomaryov | in having gloabl value | 13:33 |
| arnewiebalck | vponomaryov: global per project: yes, global global: no :) | 13:33 |
| vponomaryov | arnewiebalck: do you use "user"-based quotas? | 13:34 |
| arnewiebalck | vponomaryov: no | 13:34 |
| vponomaryov | arnewiebalck: do you know someone who does? | 13:34 |
| arnewiebalck | vponomaryov: project is the smallest entity we use | 13:34 |
| *** tommylikehu_ has joined #openstack-manila | 13:34 | |
| vponomaryov | arnewiebalck: in your case project equals to user? | 13:35 |
| *** lpetrut has quit IRC | 13:35 | |
| arnewiebalck | vponomaryov: no, I don’t, but that doesn’t mean much I guess | 13:35 |
| arnewiebalck | tbarron is probably in a better position to answer? | 13:35 |
| vponomaryov | tbarron? )) | 13:36 |
| tbarron | cinder does have some users of hierachical quotas (b/c they hit bugs in the implementation of same) | 13:36 |
| tbarron | cinder doesn't have per-user-quotas | 13:37 |
| vponomaryov | but manila inherited it from cinder | 13:37 |
| tbarron | but the hierarchy can have a single user in the lowest rank subproject | 13:37 |
| *** lpetrut has joined #openstack-manila | 13:37 | |
| tbarron | vponomaryov: no, not per-user | 13:37 |
| tbarron | vponomaryov: neutron has per-user | 13:37 |
| tbarron | neutron and manila have per-user and per-project | 13:38 |
| tbarron | cinder has hierarchical | 13:38 |
| vponomaryov | sooo consistent ) | 13:38 |
| tbarron | vponomaryov: yeah, that's why I'm not too worried about consistency on this one front until more significant re-architecting is done | 13:39 |
| arnewiebalck | tbarron: nova has per user as well, no? | 13:39 |
| tbarron | arnewiebalck: I *think* so, don't remember for sure | 13:40 |
| tbarron | but a lot of the nova people are onboard with this initiative to have keystone keep limits, hierarchically | 13:40 |
| * tbarron chases down that review | 13:40 | |
| smcginnis | Someone needs to own it all. | 13:40 |
| vponomaryov | tbarron: addition of per-share-type logic is kind of significant change | 13:40 |
| tbarron | smcginnis: do you have that review handy, you just commented on it | 13:41 |
| smcginnis | https://review.openstack.org/#/c/440815/ | 13:41 |
| tbarron | smcginnis: ty! | 13:41 |
| smcginnis | tbarron: No problem. | 13:41 |
| tbarron | vponomaryov: well, I was thinking it could be a relatively straightforward port w/o too much significant change, but | 13:42 |
| tbarron | vponomaryov: I'm not *against* you fixing things up well while you are in there :D | 13:42 |
| vponomaryov | tbarron: from architecture point of view, there is more correct way to solve it, but it is much bigger change than port of Cinder's way | 13:43 |
| vponomaryov | in both cases we solve use case | 13:43 |
| vponomaryov | only one of them is consistent with Cinder | 13:44 |
| tbarron | vponomaryov: I kinda lean towards just porting the cinder change and doing the more correct approach when we figure whether/how we'll work with https://review.openstack.org/#/c/440815/ and with OSC | 13:45 |
| tbarron | vponomaryov: those two things won't be in this release | 13:45 |
| tbarron | vponomaryov: and when we address those two we should definitely make every effort to engage with cinder and come to a common, properly architected solution. | 13:46 |
| vponomaryov | could be in parallel universe )) sounds sooo futuristic )) | 13:47 |
| tbarron | vponomaryov: yeah, I hear you. If you want to do something cleaner now I certainly won't stand in the way either. | 13:48 |
| tbarron | vponomaryov: but from a project standpoint I favor you using less resources to handle this use case and | 13:49 |
| tbarron | vponomaryov: you putting your skills and resources into other stuff in this release that wouldn't get done | 13:49 |
| tbarron | vponomaryov: if you do the very clean arch approach to this | 13:49 |
| vponomaryov | yeah, it is rare case when I push my excellence deep in, kkhhhm, something, and do less efforts )) | 13:49 |
| vponomaryov | excellence-perseption | 13:50 |
| tbarron | vponomaryov: I know you want to do it right and as I say I won't get in the way :D | 13:50 |
| tbarron | vponomaryov: but I hope that all our near term quota work will be throw-away work in a couple more releases | 13:51 |
| vponomaryov | tbarron: it should been done long time ago, actually | 13:51 |
| vponomaryov | s/been/have benn/ | 13:51 |
| vponomaryov | >_< typo-driver conversation detected ) | 13:51 |
| vponomaryov | >_< | 13:52 |
| tbarron | IMO the whole quota-reservations thing needs re-thinking and it needs a cross-project solution. | 13:52 |
| tbarron | It won't come totally top-down though. | 13:52 |
| tbarron | It will come by projects talking to one another and working towards convergence by doing parallel implementations, then abstracting out common stuff. | 13:53 |
| tbarron | Rather than by a top-down service just being provided ... | 13:53 |
| tbarron | keystone seems like a natural fit for keeping hierarchical limit info | 13:53 |
| tbarron | but even there we have to have that as a plugin-modules, as it were, so that when manila and cinder run standalone/noauth, they can still do quotas | 13:54 |
| vponomaryov | tbarron: haven't read spec yet, does it include "usages" in its idea too? | 13:54 |
| vponomaryov | tbarron: or only limits? | 13:54 |
| tbarron | vponomaryov: i haven't checked it lately, but I'm pretty sure only limits in keystone. | 13:55 |
| *** tommylikehu_ has quit IRC | 13:55 | |
| vponomaryov | tbarron: why so? | 13:55 |
| tbarron | vponomaryov: a library for calculating usages might also make sense (with the actual quantities/metrics defined in projects) | 13:56 |
| *** tommylikehu_ has joined #openstack-manila | 13:56 | |
| vponomaryov | tbarron: "usages" will exist anyway | 13:56 |
| vponomaryov | and exactly conjuction of limits and usages makes sense | 13:56 |
| tbarron | vponomaryov: you should participate in that review | 13:57 |
| tbarron | vponomaryov: I lean towards the jaypipes perspective that we shouldn't even track usages and reservations, just claims, but it's been a while since I made my head hurt with this stuff | 13:58 |
| vponomaryov | tbarron: "made my head hurt" LOL | 13:59 |
| tbarron | vponomaryov: I *think* the put limits in keystone proposal is a *start* on some common infra for quotas, but not | 13:59 |
| tbarron | thought to be the whole story on how to make quotas work consistently across projects | 14:00 |
