| ttx | oneswig is not in channel | 09:02 |
| etp | hi | 09:02 |
| belmoreira | hi, thank for ping ttx | 09:02 |
| ttx | masahito: how is the situation in Japan, masahito ? | 09:02 |
| masahito | Not good :-< | 09:03 |
| masahito | I'm working from home everyday.... | 09:03 |
| ttx | ok, same here | 09:03 |
| masahito | But not a lock down, so I can go out side | 09:04 |
| ttx | ah, here we are under strict lockdown | 09:04 |
| ttx | (France) | 09:04 |
| *** ociuhandu has joined #openstack-meeting | 09:04 | |
| raymonddeng | where are you guys? i'm in los angeles, ca | 09:04 |
| raymonddeng | most people work remotely right now here | 09:04 |
| ttx | raymonddeng: mostly Europe (belmoreira, oneswig, amorin, me) and Asia (masahito, jiaopengju2...) | 09:05 |
| mdelavergne | France also | 09:05 |
| ttx | ok, let's get started | 09:05 |
| *** tetsuro has quit IRC | 09:05 | |
| ttx | Our agenda for today is at: | 09:05 |
| ttx | #link https://etherpad.openstack.org/p/large-scale-sig-meeting | 09:05 |
| ttx | I'll reorder the topics to give amorin and oneswig some time to join | 09:06 |
| ttx | #topic Large scale operations now-virtual OpenDev track | 09:06 |
| *** openstack changes topic to "Large scale operations now-virtual OpenDev track (Meeting topic: large_scale_sig)" | 09:06 | |
| ttx | #link https://etherpad.openstack.org/p/LargeScaleOps_OpenDev | 09:06 |
| ttx | We had a TODO for everyone to check/comment that etherpad... | 09:06 |
| ttx | belmoreira: I suspect there will be changes to it as you all work out how to run it virtually ? | 09:06 |
| belmoreira | I don't have more information... I think the work done will be re-used | 09:08 |
| ttx | yeah, the general idea is to start the discussion on those topics through online sessions | 09:08 |
| ttx | but some tracks are more likely to be successful at that than others | 09:08 |
| *** ociuhandu has quit IRC | 09:08 | |
| ttx | so in the coming weeks there will be a set of discussions to see what should be done | 09:09 |
| ttx | I'd say reviewing the etherpad is still useful, in that context | 09:09 |
| ttx | belmoreira: anything else on that topic ? | 09:09 |
| belmoreira | no, when I have more info I will let you know | 09:10 |
| ttx | #topic Progress on "Scaling within one cluster" goal | 09:10 |
| *** openstack changes topic to "Progress on "Scaling within one cluster" goal (Meeting topic: large_scale_sig)" | 09:10 | |
| ttx | #link https://etherpad.openstack.org/p/large-scale-sig-cluster-scaling | 09:10 |
| ttx | We had one TODO for everyone to review new patchset of oslo.metrics spec | 09:10 |
| ttx | #link https://review.opendev.org/#/c/704733/ | 09:10 |
| ttx | masahito: do you plan to add the metrics information schema in a new patchset ? | 09:11 |
| ttx | it seems to be the only item missing at this point before approval | 09:12 |
| masahito | I want, but I'm not sure when I can finish it. | 09:13 |
| ttx | masahito: would you rather wait, or push for approval at the current version ? | 09:13 |
| masahito | Is the actual information required to be approved? | 09:13 |
| ttx | masahito: probably not, we could push for approval under the current version | 09:13 |
| ttx | I think bnemec was interested in getting the code out there as soon as possible | 09:14 |
| ttx | so I'd rather focus on that part than on documenting the spec | 09:14 |
| masahito | Ah, okay. then please push the patch set to be approved to make things forwards. | 09:14 |
| ttx | masahito: when do you think the code could be pushed ? | 09:15 |
| ttx | (I can also push for repository creation if it's ready, but I suspect you ahve to check a lot of things before doing that) | 09:15 |
| ttx | #action ttx to push for oslo.metric spec approval | 09:16 |
| masahito | maybe until end of April? I'm a bit busy in other task right now. | 09:16 |
| ttx | masahito: I can imagine. No worry, just wondering about the general timeframe. So the spec approval is not super-urgent | 09:17 |
| ttx | but would be good to have in the coming weeks | 09:17 |
| ttx | #info masahito thinks the oslo.metric code could be pushed by end of April at the earliest | 09:18 |
| *** slaweq has joined #openstack-meeting | 09:18 | |
| ttx | OK, otherwiose we had no recent story posted on https://etherpad.openstack.org/p/scaling-stories | 09:18 |
| ttx | oneswig had a TODO to contribute a scaling story on bare metal cluster scaling, but that was not done yet | 09:18 |
| ttx | So I'll push it back to next meeting | 09:18 |
| ttx | #action oneswig to contribute a scaling story on bare metal cluster scaling | 09:19 |
| ttx | Anything else on the "Scaling within one cluster" goal ? | 09:19 |
| ttx | ok, next topic then | 09:19 |
| ttx | #topic Progress on "Documenting large scale operations" goal | 09:20 |
| *** openstack changes topic to "Progress on "Documenting large scale operations" goal (Meeting topic: large_scale_sig)" | 09:20 | |
| ttx | #link https://etherpad.openstack.org/p/large-scale-sig-documentation | 09:20 |
| ttx | We had two TODOs for amorin from last meeting | 09:20 |
| ttx | I haven't seen anything posted, but I may have missed it | 09:20 |
| ttx | In doubt Ill push back those TODOs to next meeting | 09:20 |
| ttx | #action amorin to create a wiki page for large scale documentation | 09:21 |
| ttx | #action amorin to propose patch against Nova doc | 09:21 |
| ttx | we discussed privsep in recent meetings... note that continuing the transition to privsep has been proposed as a Victoria (next cycle) goal: | 09:21 |
| ttx | #link http://lists.openstack.org/pipermail/openstack-discuss/2020-March/013409.html | 09:21 |
| ttx | Feel free to chime in on that thread to encourage this, with your operator hat on ! | 09:22 |
| ttx | (it's not clear for everyone that this goal would have operational benefits) | 09:22 |
| ttx | I'll try to help with that community goal | 09:23 |
| ttx | Anything else on "Documenting large scale operations" ? | 09:23 |
| ttx | #topic Next meeting | 09:23 |
| *** openstack changes topic to "Next meeting (Meeting topic: large_scale_sig)" | 09:23 | |
| ttx | We can do next meeting in two weeks, April 8. | 09:24 |
| ttx | Since Europe will switch to DST next week, we could easily move the meeting to 8 UTC (one hour earlier for Japan and China) if that helps | 09:24 |
| ttx | raymonddeng, masahito: would it be better or worse for you? | 09:24 |
| raymonddeng | it's about the same for me | 09:25 |
| masahito | It works for me. | 09:26 |
| ttx | belmoreira: any preference? | 09:26 |
| ttx | (8utc would keep it at 10am for us) | 09:26 |
| ttx | ok, let's try it | 09:27 |
| ttx | #info next meeting: April 8, 8:00UTC | 09:27 |
| ttx | I'll post the meeting change to update the meeting calendar and all. | 09:28 |
| ttx | #topic Open discussion | 09:28 |
| *** openstack changes topic to "Open discussion (Meeting topic: large_scale_sig)" | 09:28 | |
| ttx | raymonddeng: was there anything specific you wanted to discuss? Any particular reason for joining the SIG? | 09:28 |
| ttx | (like, are you running a large scale deployment yourself?) | 09:28 |
| ttx | FWIW, the SIG has tried to avoid boiling the ocean, and that's why we tried to set reasonable, focused goals to start | 09:29 |
| ttx | but the SIG obviously goes where its active members push it, so if there is anything you'd like to lead, it's pretty open :) | 09:30 |
| raymonddeng | no i didn't have anything specific to discuss, i found this sig a few hours ago and was fortunate that the meeting was about to start | 09:31 |
| ttx | ah! perfect timing indeed | 09:31 |
| raymonddeng | i'm a university student interested in 'large scale infrastructure', doing some devops stuff at Code for America and another company and wanted to see what this sig was about see what was | 09:31 |
| raymonddeng | oops, **and wanted to see what this sig was about | 09:31 |
| raymonddeng | yeah very fortunate timing | 09:32 |
| *** raymonddeng has quit IRC | 09:32 | |
| ttx | The general goal is to try to regroup people with common problems, so that they can work on common solutions | 09:32 |
| *** ykatabam has quit IRC | 09:32 | |
| ttx | ah, we lost raymond | 09:32 |
| mdelavergne | this timing was not so fortunate :p | 09:33 |
| ttx | lol | 09:33 |
| *** raymonddeng has joined #openstack-meeting | 09:33 | |
| ttx | Oh well, that probably means the meeting is over, unless anyone has anything more to discuss? | 09:33 |
| ttx | raymonddeng: Welcome back! The general goal of SIGs is to try to regroup people with common problems, so that they can work on common solutions | 09:33 |
| ttx | So here we are trying to regroup operators of large scale infrastructure (based on openstack) so that they share problems and work on solutions | 09:34 |
| ttx | traditionally everyone work on solutions on their side, resulting in lots of duplication of effort | 09:34 |
| *** dmacpher has joined #openstack-meeting | 09:35 | |
| ttx | and the software does not get any better in handling the problems for the next person | 09:35 |
| ttx | This SIG is trying to solve that, pool resources to work on the same objectives, and ultimately improve the software | 09:36 |
| ttx | It's not easy, as we all have other day jobs, but it's important :) | 09:36 |
| ttx | And on those good words, I think we can close today's meeting, unless anyone else has anything to add | 09:37 |
| raymonddeng | definitely very important, really impressive that you guys handle day jobs and os contributions | 09:37 |
| raymonddeng | hope i can help out in some capacity! | 09:37 |
| ttx | raymonddeng: I hope so! Thanks for joining | 09:38 |
| ttx | Thanks everyone for attending the meeting! Stay safe! | 09:38 |

| verdurin | Morning. | 11:01 |
| oneswig | hi all | 11:01 |
| janders | here packets are still allowed to leave NIC ports, we'll see for how long | 11:01 |
| belmoreira | hello | 11:02 |
| oneswig | all healthy here | 11:02 |
| janders | that's great to hear :) | 11:03 |
| oneswig | There isn't an agenda today - apologies - I've been helping with a training workshop this week | 11:03 |
| janders | no worries | 11:03 |
| oneswig | I've heard a few things related to coronavirus and providing compute resources to help research | 11:06 |
| oneswig | Anyone else active in this? | 11:06 |
| verdurin | Yes, we're active there - lots of frantic requests and cluster re-arrangements. | 11:07 |
| janders | we're under change moratorium to make sure systems are up and running for COVID research | 11:07 |
| janders | personally I'm not involved in anything beyond this at this point in time :( | 11:07 |
| oneswig | I registered for folding@home, but in 2 days (so far) I've had just 1 work unit... apparently the response has been so huge their queues have drained. | 11:08 |
| oneswig | What form is the compute workload taking? | 11:08 |
| oneswig | janders: I assume the fires are all done with, or is that still ongoing in the background? | 11:11 |
| janders | luckily, yes | 11:11 |
| janders | on to the next crisis | 11:11 |
| verdurin | We have some people preparing to work on patient data, others running simulations. | 11:12 |
| verdurin | Some working on drug targets/therapies. | 11:12 |
| oneswig | verdurin: from the news I've seen Oxford University does appear to be very active. | 11:12 |
| verdurin | Yes. I wasn't deemed glamorous enough to appear on the News, though. | 11:13 |
| oneswig | Ah | 11:13 |
| oneswig | Elsewhere I've not heard how it's affecting IT supply chains but inevitably there must be consequences. | 11:14 |
| verdurin | It has. We had to pay over the odds for some parts to ensure timely delivery, by going with the only vendor who had stock already. | 11:15 |
| oneswig | janders: is Canberra in lockdown? We started in earnest this week. | 11:16 |
| janders | partially, yes | 11:16 |
| janders | though comms aren't particularly clear | 11:16 |
| janders | we've been working from home for weeks now so not much change | 11:17 |
| janders | but the authorities are gradually cracking down on pretty much anything | 11:17 |
| oneswig | Did you see that Ceph Octopus has been released? | 11:20 |
| janders | not yet... are there any new features or improvements relevant to HPC? | 11:21 |
| janders | RDMA support, improvements to CephFS? | 11:21 |
| oneswig | From what I've heard the Ceph-Ansible support is doubtful. A pity considering it tends to work well nowadays | 11:21 |
| janders | thats unfortunate | 11:22 |
| oneswig | I think there may be less support for RDMA, but an opportunity to do it better second time round. | 11:22 |
| oneswig | I'm not sure this represents the official plan of record but it's along the right lines: https://docs.ceph.com/docs/master/dev/seastore/ | 11:24 |
| verdurin | The big thing I noticed is this new 'cephadm' tool. | 11:25 |
| oneswig | verdurin: is that part of the orchestrator? | 11:27 |
| *** raildo has joined #openstack-meeting | 11:31 | |
| verdurin | It's a new installation tool that is yes somehow integrated with the orchestrator. | 11:34 |
| verdurin | I just scanned the release notes and flipped through the new docs, though. | 11:39 |
| janders | on another note, I had a chance to finally get back to VPI work on CX6 and I did get it to work with MOFED5 and latest FW | 11:39 |
| janders | will probably use it more over the coming weeks | 11:39 |
| janders | one interesting challenge I ran into is - how to tackle dual-PCIe-slot setup for 100/200GE | 11:40 |
| verdurin | janders: was this with newer firmware than before or did you need to do something different? | 11:40 |
| janders | verdurin: newer firmware | 11:40 |
| janders | I had issues with VPI in the past and ended up using onboard 10GE for ethernet comms | 11:40 |
| janders | now I'm trying to move back to the Mellanox cards | 11:40 |
| janders | where it gets interesting is - for the dual-slot, dual-port card, how to wire this up to ovs? | 11:41 |
| janders | it comes out as two ports | 11:41 |
| janders | even though physically it's one | 11:41 |
| janders | with IB it's easy as multipathing is more natural | 11:41 |
| *** rpittau is now known as rpittau|bbl | 11:42 | |
| verdurin | Ah, you have the dual-slot card. We haven't used any of those yet. | 11:42 |
| janders | with ethernet I'm not sure - do you guys have any experience with that? | 11:42 |
| janders | yes | 11:42 |
| janders | they work beautifully for storage, even if they are a little convoluted | 11:42 |
| *** oneswig_ has joined #openstack-meeting | 11:43 | |
| oneswig_ | sorry, dropped off | 11:43 |
| *** eharney has quit IRC | 11:44 | |
| janders | I will likely chat to Mellanox about this over coming days, happy to relay back what I learned if you're interested | 11:45 |
| janders | it seems that for non-performance-sensitive workloads, just using one of the two interfaces will suffice | 11:45 |
| *** oneswig has quit IRC | 11:45 | |
| janders | what im wondering about though is if we're using leftover PCIe bandwidth for ethernet traffic, maybe it's better for IB if ethernet load balances across PCIe slots as well | 11:46 |
| janders | IB likes symmetry | 11:46 |
| janders | if each card gets say 12.5GB/s but we try to snap 5GB/s on one port for eth, I am not too sure if we still get 20GB/s on IB using what's left | 11:47 |
| janders | so this may be motivation for figuring this out | 11:47 |
| janders | to prevent IB slowdowns due to intermittent ethernet bandwidth peaks | 11:47 |
| verdurin | Hmm. Sounds potentially troublesome, as you say. | 11:48 |
| janders | yeah | 11:48 |
| verdurin | Would be interested to hear. | 11:48 |
| janders | dual-slot CX6s are fast but tricky to drive at times | 11:48 |
| janders | luckily GPFS uses them very efficiently | 11:48 |
| oneswig_ | Surprising that VPI has been an issue, you'd think a lot of people would want that. | 11:48 |
| janders | I think it got fixed initially around October, but that had the limitation of having to use a specific port for IB, wouldn't work other way round | 11:49 |
| *** eharney has joined #openstack-meeting | 11:49 | |
| janders | I think now it is fully functional | 11:49 |
| janders | new MOFED packaging convention is interesting though | 11:50 |
| janders | the archive has multiple repos and accidentally using more than one leads to dependency hell | 11:50 |
| janders | I think it's been like that since around 4.7 but I only really looked into this today on 5.0 | 11:50 |
| oneswig_ | oh no... | 11:50 |
| janders | makes sense when you really look through but takes a while to get used to | 11:50 |
| oneswig_ | We've been using this - https://github.com/stackhpc/stackhpc-image-elements/tree/master/elements/mlnx-ofed - but sometimes the kernel weak-linkage doesn't work correctly, perhaps it's related to the synthetic DIB build environment. | 11:52 |
| janders | yeah I had some issues with weak linkage in the past | 11:52 |
| janders | best rebuild against a specific kernel revision | 11:53 |
| *** ykatabam has joined #openstack-meeting | 11:54 | |
| *** rh-jelabarre has joined #openstack-meeting | 11:56 | |
| oneswig_ | That can be tricky in diskimage-builder, but I expect there's a way through. | 11:57 |
| oneswig_ | Nearly at time | 11:58 |
| janders | stay safe everyone :) | 11:58 |
| oneswig_ | same to you! | 11:58 |
| janders | hopefully there won't be curfew on internet comms next week :) | 11:58 |
| oneswig_ | overload, more like. | 11:58 |
| janders | I don't think COVID transmits through RDMA though | 11:59 |
| janders | so that may be the safest comms channel :) | 11:59 |
| oneswig_ | cheers all | 12:02 |

| liuyulong | Recall the team Announcements | 14:05 |
| liuyulong | Since we are an online community at most time, a virtual PTG should work for our community members. | 14:07 |
| liuyulong | #link https://www.openstack.org/events/opendev-ptg-2020/ | 14:07 |
| liuyulong | So the Vancouver PTG is officially cancelled. | 14:08 |
| liuyulong | I've been working from home about 2 months. | 14:10 |
| liuyulong | And more days may still be needed. | 14:11 |
| liuyulong | So, take care of yourself guys. | 14:11 |
| slaweq | liuyulong: thx, I'm working from home for last 2 years already ;) | 14:11 |
| liuyulong | slaweq, cool, good to know that. | 14:11 |
| liuyulong | slaweq, you are really safe now and then. | 14:12 |
| liuyulong | OK, according to the bug deputy email | 14:12 |
| liuyulong | #link http://lists.openstack.org/pipermail/openstack-discuss/2020-March/013510.html | 14:12 |
| liuyulong | IMO, no L3 bugs last week. | 14:12 |
| liuyulong | So, anyone has bug to discuss here? Or let's just go next topic. | 14:13 |
| liuyulong | OK | 14:14 |
| liuyulong | #topic OVN_L3 | 14:14 |
| *** openstack changes topic to "OVN_L3 (Meeting topic: neutron_l3)" | 14:14 | |
| liuyulong | #link https://bugs.launchpad.net/neutron/+bug/1867869 | 14:14 |
| openstack | Launchpad bug 1867869 in neutron "[OVN] Remove dependency on fip_object" [Low,In progress] - Assigned to zhanghao (zhanghao2) | 14:14 |
| ralonsoh | this is still ongoing | 14:15 |
| liuyulong | One bug from OVN | 14:15 |
| ralonsoh | we need to know if this will be needed in QoS FIP | 14:15 |
| ralonsoh | so, IMO, I'll wait to remove this dependency | 14:16 |
| liuyulong | ralonsoh, sure, thank you for the information. Mostly are TODOs from lucasagomes, IMO, he may also have a deep review. | 14:17 |
| liuyulong | He is already in the list. | 14:18 |
| *** maciejjozefczyk_ is now known as maciejjozefczyk | 14:19 | |
| liuyulong | Next should be the patch: | 14:19 |
| liuyulong | #link https://review.opendev.org/#/c/705660/ | 14:19 |
| liuyulong | I run it locally last week, it works. But it now needs a rebase. | 14:19 |
| ralonsoh | maciejjozefczyk, ^ | 14:20 |
| ralonsoh | I'll ping him in gerrit or IRC | 14:21 |
| maciejjozefczyk | ralonsoh, thanks for testing! | 14:22 |
| liuyulong | Sure, I will run the rebased code again if I have enough time. : ) | 14:22 |
| maciejjozefczyk | I'll rebase it | 14:22 |
| liuyulong | #link https://review.opendev.org/#/c/710881/2/doc/source/ovn/gaps.rst | 14:23 |
| liuyulong | This is from the gaps from between ML2/OVS and OVN, most of them looks like are related to L3. | 14:23 |
| maciejjozefczyk | Ok, so for 'QoS for Layer 3 IPs': This week I tested OVN QoS on FIP - there is a possibility. Its only a matter of proper match in QoS row. | 14:24 |
| maciejjozefczyk | #link: https://mail.openvswitch.org/pipermail/ovs-discuss/2020-March/049857.html | 14:25 |
| liuyulong | I want to say that "QoS for Layer 3 IPs" has the higher priority from the perspective of cloud provider. | 14:25 |
| liuyulong | Datacenter could not ensure that every external IPs to reach the max bandwidth at the same time. | 14:26 |
| *** psachin has quit IRC | 14:27 | |
| *** Adri2000 has joined #openstack-meeting | 14:29 | |
| liuyulong | maciejjozefczyk, cool, so just logical flows should be added from L3_ovn plugin to north DB, and then ovn-controller, gateway chassis should do the meters installation. | 14:31 |
| maciejjozefczyk | liuyulong, yes. For now we're working on refactor of adding of QoS rows in NBDB table. From this table the Logical Flows are generated. | 14:33 |
| maciejjozefczyk | After a refactor that would be possible to add specific QoS row that will match a FIP | 14:33 |
| maciejjozefczyk | from Core OVN perspective its possible and I tested it manually, N/S traffic is shaped, while E/W not :) | 14:33 |
| liuyulong | So the OVN DB schema should be refactored first at core OVN? | 14:36 |
| *** ociuhandu has joined #openstack-meeting | 14:36 | |
| liuyulong | OK, I found the answer. https://mail.openvswitch.org/pipermail/ovs-discuss/2020-March/049863.html | 14:37 |
| maciejjozefczyk | liuyulong, There is no need to change anything in Core OVN - in relation to QoS on FIP. | 14:38 |
| liuyulong | "inport == \"96242e8f-602f-4077-984a-5659e84a8c4f\" && ip4.src == 172.24.5.126 && is_chassis_resident(\"cr-lrp-96242e8f-602f-4077-984a-5659e84a8c4f\")" | 14:40 |
| liuyulong | I'm not quite sure about this, so in gateway chassis, the packet has already be NATed (source IP) to floating IP. | 14:41 |
| maciejjozefczyk | liuyulong, yes, Neutron, while creating the QoS row should define match similar to this oen | 14:41 |
| liuyulong | But, what about the ingress from outside world, the destination IP is floating IP. | 14:41 |
| ralonsoh | that will be another rule | 14:42 |
| ralonsoh | depending on the rule direction | 14:42 |
| ralonsoh | the OVN qos rules will match the Neutron QoS ones | 14:42 |
| ralonsoh | and will add the needed "match" field in the NB | 14:43 |
| ralonsoh | (matching src/dst IP or whatever is needed) | 14:43 |
| maciejjozefczyk | liuyulong, yes, the match field in the rule will look differently | 14:43 |
| liuyulong | So, this line is only for egress (from the perspective of VM) to outside world. | 14:44 |
| ralonsoh | yes | 14:44 |
| liuyulong | ralonsoh, maciejjozefczyk, thank you guys, : ) | 14:44 |
| liuyulong | OK, no more OVN related things from me then. | 14:45 |
| liuyulong | Any updates? | 14:45 |
| liuyulong | OK, let's move on. | 14:46 |
| liuyulong | #topic On demand agenda | 14:46 |
| *** openstack changes topic to "On demand agenda (Meeting topic: neutron_l3)" | 14:46 | |

| *** lajoskatona has joined #openstack-meeting | 14:47 | |
| liuyulong | I rebased the patch https://review.opendev.org/#/c/662111/ from Swaminathan, hope we could continue the work. | 14:47 |
| *** jraju__ has joined #openstack-meeting | 14:49 | |
| haleyb | liuyulong: yes, that would be good to move forward. We should think about OVN as well | 14:49 |
| *** links has quit IRC | 14:49 | |

| liuyulong | I will test Swaminathan's patch more deeply locally, and comment the feedback. | 14:56 |

| timburke | #topic surveys | 21:02 |
| *** openstack changes topic to "surveys (Meeting topic: swift)" | 21:02 | |
| timburke | the 2020 user survey is out! | 21:02 |
| timburke | #link https://www.openstack.org/user-survey/survey-2020/ | 21:03 |
| timburke | help inform the foundation/tc/projects about what's getting used and how, and where things could be improved :-) | 21:03 |
| timburke | there's *also* some kind of special survey going on... | 21:04 |
| timburke | #link http://lists.openstack.org/pipermail/openstack-discuss/2020-March/013577.html | 21:04 |
| timburke | which references... | 21:04 |
| timburke | #link https://openstackfoundation.formstack.com/forms/10_years_of_openstack | 21:04 |
| timburke | i don't think there's much more to say about them. they exist, i plan on filling them out :-) | 21:05 |
| clayg | o/ | 21:05 |
| timburke | #topic virtual PTG | 21:06 |
| *** openstack changes topic to "virtual PTG (Meeting topic: swift)" | 21:06 | |
| timburke | i created an etherpad to start collecting topic | 21:06 |
| timburke | #link https://etherpad.openstack.org/p/swift-ptg-victoria | 21:06 |
| timburke | i think it's going to be interesting making this be a good, useful time for us, but i know we're up for it | 21:07 |
| mattoliverau | it sux that the PTG was cancelled, but actually works out well for me :) | 21:07 |
| timburke | me too :-) i wasn't going to be able to go otherwise | 21:08 |
| kota_ | :-) | 21:08 |
| mattoliverau | \o/ | 21:08 |
| *** jmasud has quit IRC | 21:10 | |
| timburke | as it gets closer, i'll send out some surveys about what time slots people will be around for -- i wonder if it might make sense to stagger the times over the course of the week, with the expectation that not everyone will attend every session | 21:10 |
| alecuyer | sounds good | 21:10 |
| timburke | otoh, clayg and i both seem to post reviews at all hours, so maybe we just optimize for asia/europe and make it work :P | 21:11 |
| timburke | (hopefully rledisez and tdasilva don't kill me ;-) | 21:11 |
| timburke | things to consider, anyway | 21:12 |
| mattoliverau | lol | 21:12 |
| rledisez | i'm pretty sure I can make it, I'm kinda an early bird usually ;) | 21:12 |
| timburke | that's all i had by way of announcements -- any comments or questions on them? | 21:12 |
| timburke | on to updates! | 21:14 |
| zaitcev | Kernel used to run over e-mail. It took me a while to get used to how meeting-happy OpenStack was. | 21:14 |
| timburke | #topic waterfall EC | 21:14 |
| *** openstack changes topic to "waterfall EC (Meeting topic: swift)" | 21:14 | |
| *** jgriffith has quit IRC | 21:14 | |
| timburke | clayg, i heard you were working on a third attempt | 21:15 |
| *** enriquetaso has quit IRC | 21:17 | |
| timburke | maybe it's still not to a point worth bringing up ;-) | 21:18 |
| timburke | i remember hearing admiration for torgomatic, and having everything feel almost-but-not-quite related enough to have it all make sense | 21:19 |
| timburke | #topic lots of small files | 21:19 |
| *** openstack changes topic to "lots of small files (Meeting topic: swift)" | 21:19 | |
| timburke | alecuyer, rledisez, how's it going? | 21:19 |
| alecuyer | I posted some patches we had there we had not pushed, thanks Tim for looking at these | 21:20 |
| timburke | 👍 | 21:20 |
| alecuyer | Otherwise, I have been running POCs about volume selection when writing, and storing object metadata in the DB. That's about it | 21:20 |
| timburke | sounds good | 21:20 |
| *** jamesmcarthur has quit IRC | 21:21 | |
| timburke | i'm still a little unsure about what to do for p 713914 | 21:21 |
| patchbot | https://review.opendev.org/#/c/713914/ - swift (feature/losf) - Add a sleep() between index-server health checks - 1 patch set | 21:21 |
| *** jamesmcarthur has joined #openstack-meeting | 21:21 | |
| *** jgriffith has joined #openstack-meeting | 21:21 | |
| alecuyer | I think I will remove the hardcoded sleep(10) from the other patch that prompted this one, so we can go ahead and think about how to do handle the health checks properly on slow machines | 21:22 |
| timburke | it sounds like you have a similar sleep added in the replicator & reconstructor -- but rledisez and zaitcev seemed hesitant to turn it into a config option... should we just bump up the timeout? or ... something else? | 21:22 |
| rledisez | I think for replicator/reconstructor we can just do a getmtime() on ring and optimize it. though, 0.1 second is like really small, maybe bump it a little (like 1s, 2 s?) | 21:23 |
| zaitcev | I was hoping that 0.01 would be sufficient for everyone. | 21:23 |
| rledisez | for LOSF, I don't know it we can "optimize" the current check or if bumping the sleep is the only solution | 21:23 |
| alecuyer | I can cache that result a few seconds in the health check - but we also have the issue with "regular" daemons, on atom CPUs | 21:24 |
| *** jamesmcarthur has quit IRC | 21:26 | |
| rledisez | I'm thinking, currently, there is only non-essential daemon that use this class (replicator, reconstructor, …), right? it can't hurt to be a little slower to spawn new process. it can even save of a situation where process is just diying and is respawned continuously | 21:27 |
| rledisez | non-essential == not in the data-path | 21:28 |
| timburke | seems reasonable | 21:28 |
| timburke | thanks | 21:28 |
| timburke | #topic cors | 21:29 |
| *** openstack changes topic to "cors (Meeting topic: swift)" | 21:29 | |
| timburke | so i've tried to get a minimal chain for the s3api change that i'm actually looking for | 21:29 |
| timburke | p 533028, p 710330, p 710355 | 21:30 |
| patchbot | https://review.opendev.org/#/c/533028/ - swift - Add some functional CORS tests - 11 patch sets | 21:30 |
| patchbot | https://review.opendev.org/#/c/710330/ - swift - s3api: Pass through CORS headers - 7 patch sets | 21:30 |
| patchbot | https://review.opendev.org/#/c/710355/ - swift - s3api: Allow CORS preflight requests - 10 patch sets | 21:30 |
| timburke | i know clayg has looked at the new cors tests long enough to kick out p 713754 and p 714714, thanks! | 21:31 |
| patchbot | https://review.opendev.org/#/c/713754/ - swift - Move cors out of functests (ABANDONED) - 2 patch sets | 21:31 |
| patchbot | https://review.opendev.org/#/c/714714/ - swift - Add &test= query param to CORS test infra - 1 patch set | 21:31 |
| timburke | but i also got a sense that he's hesitant to take on maintaining some new one-off javascript testing framework (which is fair) | 21:32 |
| timburke | how does everyone else feel about that? i just don't know how i can get a feel for how cors works without writing some javascript... | 21:33 |
| rledisez | I assume there is no way to simulate a browser behavior without a real browser javascript? | 21:35 |
| rledisez | could it be an external service that do that? I don't like it, but the day that service change… | 21:36 |
| timburke | i suppose i could... but i'd really worry about how well it'd actually match what real browsers *do* -- i've already spotted places where browsers don't interpret the spec the same way, so different headers get exposed depending on which browser you're using | 21:37 |
| timburke | see p 712238 | 21:37 |
| patchbot | https://review.opendev.org/#/c/712238/ - swift - cors: Add Content-Length to default-exposed headers - 5 patch sets | 21:37 |
| *** jamesmcarthur has joined #openstack-meeting | 21:41 | |
| *** jgriffith has quit IRC | 21:41 | |
| timburke | something to think about, anyway. maybe i should look at writing some (python) func tests for those; between func & unit i'd feel pretty good about us being unlikely to regress, so maybe we could flip the order on the chain and let p 533028 be a separate, longer discussion... | 21:42 |
| patchbot | https://review.opendev.org/#/c/533028/ - swift - Add some functional CORS tests - 11 patch sets | 21:42 |
| zaitcev | timburke: didn't you try to use Selenium? | 21:42 |
| *** jgriffith has joined #openstack-meeting | 21:43 | |
| timburke | zaitcev, yep, that patch adds a new gate job that uses selenium to drive a headless browser to exercise some javascript | 21:43 |
| timburke | the question is, do we really want to maintain javascript ;-) | 21:43 |
| timburke | i like the diff i got at https://review.opendev.org/#/c/710355/10/test/cors/test-s3-obj.js with the chain the way it is, though | 21:44 |
| patchbot | patch 710355 - swift - s3api: Allow CORS preflight requests - 10 patch sets | 21:44 |
| timburke | CorsBlocked -> S3ObjectOK sure feels like a win :D | 21:44 |
| *** ociuhandu has joined #openstack-meeting | 21:45 | |
| timburke | well, that was the main question i still had | 21:46 |
| timburke | #topic open discussion | 21:46 |
| *** openstack changes topic to "open discussion (Meeting topic: swift)" | 21:46 | |
| timburke | anything else to bring up this week? | 21:46 |
| zaitcev | Well, I'm still beating the drum for the dark data watcher. | 21:49 |
| zaitcev | Romain took a look, and I think I mostly answered his remarks. | 21:49 |
| zaitcev | Or completely. | 21:49 |
| *** ociuhandu has quit IRC | 21:49 | |
| rledisez | zaitcev: I'll go check that again | 21:50 |
| timburke | i'll try to take a look this week, too. there's a project i'm looking at where we somehow got some orphaned shards, so it seems not-so-crazy to me that there might be some dark data, too, by the time i've got *that* cleaned up | 21:51 |
| timburke | all right, thank you all for coming and thank you for working on swift! | 21:52 |
