| opendevmeet | The meeting name has been set to 'scientific_sig' | 11:00 |
| oneswig | greetings | 11:00 |
| oneswig | Having fun over here reclaiming disk space from a docker registry... | 11:01 |
| dh3 | hi, didn't know if there was a meeting today :) I am reviewing network change controls | 11:05 |
| oneswig | Hi dh3 there isn't an agenda, as usual I have been distracted on other matters. | 11:05 |
| belmoreira | o/ | 11:05 |
| oneswig | OpenStack-related network changes? | 11:06 |
| oneswig | hi belmoreira, welcome | 11:06 |
| belmoreira | hi oneswig | 11:06 |
| dh3 | only tangentially (more network switches to support more sequencing machines... the data will go through OpenStack at some point) | 11:06 |
| oneswig | One interesting development this week has been the arrival of OFED 5.4 for HPC networking. It doesn't appear to work out of the box for us. | 11:07 |
| oneswig | dh3: more sequencing machines? The data deluge is upon us | 11:07 |
| dh3 | always /o\ | 11:07 |
| oneswig | I suspect belmoreira is looking at similar issues for the high-luminosity upgrade? | 11:08 |
| dh3 | I had not touched OFED in years until I had to do a kernel upgrade on an elderly Lustre system a few weeks ago | 11:08 |
| oneswig | dh3: sounds potentially traumatic | 11:09 |
| belmoreira | :) | 11:09 |
| belmoreira | I would like to bring something to the SIG | 11:09 |
| oneswig | belmoreira: fire away! | 11:09 |
| belmoreira | One of the discussions in the TC is the goals for the Y release. A proposal is the "operators pain points" in the different projects. | 11:09 |
| belmoreira | One of the problems is how to collect those pain points. | 11:10 |
| oneswig | Pain points that the TC can do something about, specifically... | 11:10 |
| belmoreira | It would be great if the scientific SIG community has some feedback | 11:10 |
| dh3 | I think I remember questions in the OpenStack survey but maybe those were project-specific | 11:11 |
| oneswig | belmoreira: sounds like a good fit | 11:11 |
| belmoreira | operators pain points that the OpenStack projects can work on. The problem is that dev/operators can have a different understanding of pain points | 11:12 |
| belmoreira | that's way it would be great to have operators feedback | 11:12 |
| oneswig | belmoreira: I wonder if the TC can do anything on settling volatility in the CentOS roadmap | 11:13 |
| belmoreira | yes, OpenStack survey questions are one of the information sources. | 11:13 |
| belmoreira | oneswig ahah | 11:13 |
| belmoreira | here's the discussion in the mail list: http://lists.openstack.org/pipermail/openstack-discuss/2021-June/023352.html | 11:14 |
| dh3 | I think I will have one specific pain point later this year: in our upgrade we will be live-migrating many instances around for as close to a seamless upgrade as possible. However hardware maintenance, repairs, replacement etc have left some hypervisors subtly different (microcode version) which breaks live migration. Not sure what could be done to suggest/recommend CPU feature settings to hide this sort of thing from day 1 | 11:16 |
| belmoreira | dh3 I had that problem as well | 11:17 |
| oneswig | dh3: to compound on that, I think CentOS 8.3 revoked some flags (for TSX) - for good reasons. | 11:17 |
| belmoreira | we mitigate it using now a custom CPU features | 11:17 |
| dh3 | I guess you revisit the CPU feature set every time you have a significant hypervisor CPU change/new hardware? | 11:18 |
| dh3 | oneswig: I don't *think* that will bite us (I don't see TSX in a random VM I just checked) but good to know about, thanks | 11:19 |
| belmoreira | dh3, true those need to be revisited when the hardware is replaced | 11:22 |
| oneswig | belmoreira: what's the best way to contribute feedback to each project? | 11:24 |
| oneswig | Should we add them here - https://etherpad.opendev.org/p/y-series-goals - or suggest them for review somewhere else first? | 11:25 |
| belmoreira | oneswig that's a great question. That's not defined yet. I just wanted to give you a first heads up. | 11:25 |
| oneswig | It's a great opportunity for feedback and I hope the hard work will be on reducing a long list to a short one. | 11:26 |
| martial | morning | 11:27 |
| oneswig | Hi martial, welcome | 11:27 |
| oneswig | #chair martial | 11:27 |
| opendevmeet | Current chairs: martial oneswig | 11:27 |
| dh3 | (to be honest we have not had a huge amount of operator pain recently... clearly it's time for us to start using more projects...) | 11:27 |
| oneswig | We were just discussing operator pain points to focus on for the Y cycle | 11:28 |
| belmoreira | hi martial | 11:28 |
| martial | understood, hello all | 11:29 |
| belmoreira | unfortunately I need to leave for another meeting. I was good talking with you. | 11:29 |
| oneswig | likewise belmoreira, thanks! | 11:29 |
| dh3 | thanks, bye | 11:29 |
| belmoreira | I will give you more info when available | 11:29 |
| belmoreira | thanks | 11:29 |
| martial | okay will read the logs | 11:31 |
| oneswig | The summary is that we should canvas the SIG for pain points with specific projects. Just annoying dumb stuff that nobody ever fixed, but should have... | 11:32 |
| oneswig | I can think of one we hit the other day - I don't think Glance enforces quotas for image usage. Consistent implementation of quotas, roles and policies would be helpful. | 11:35 |
| martial | makes sense | 11:36 |
| oneswig | martial: shall we add it to the agenda for next week to produce a shortlist? | 11:37 |
| martial | maybe start a slack conversation to gather items? | 11:37 |
| oneswig | Sounds good to me. | 11:38 |
| oneswig | I can start that one martial. Is there anything else to cover today? (I'm eyeing an opportunity for lunch before the afternoon kicks off) | 11:39 |
| martial | nothing from my end | 11:40 |
| martial | go enjoy your lunch :) | 11:40 |
| oneswig | Great, thanks all, see you next time | 11:42 |
| verdurin | Very late hello/goodbye. | 11:43 |
| martial | hi verdurin | 11:43 |
| martial | we were about to close the meeting | 11:44 |
| verdurin | Yes, please go ahead. | 11:44 |
| martial | I think it is the two of us left :) | 11:44 |
| martial | #end-meeting | 11:44 |
| martial | mmh weird | 11:44 |
