I think my family has found some level of equilibrium, although not always... 21:06:02 <martial> schools have been closed for a few weeks and until the end of the school year (at least) 21:06:38 <oneswig> martial: is DataMachines work affected by everyone being at home? 21:06:51 <martial> nope I am kept crazy busy :) 21:07:26 <martial> how about the rest of you? 21:07:47 <oneswig> Seems a very popular time for people to explore remote training workshops. We are getting the hang of it. 21:08:21 <janders> my team is all over AUS so remote work didnt change things much in regards to how we work 21:08:31 <janders> we did however get nearly locked out of our shared DC 21:08:36 <janders> which is creating interesting challenges 21:09:13 <oneswig> janders: had a question with your name on it. What's the cleanest way of deploying an Ironic node without filling an entire disk with the root fs? 21:09:56 <janders> hmm... good one :) 21:10:25 <janders> so you want to partition the drive but leave empty space on the disk past the boot partition right? 21:11:00 <oneswig> They are Dell nodes with a PERC. I could maybe make a 1-node RAID group, and split it into virtual devices? Not sure if it does that. 21:11:20 <oneswig> Otherwise I was wondering about making a massive swap partition, and then not using it for swap 21:11:31 <oneswig> Or the whole-disk-image stuff, maybe. 21:12:10 <oneswig> I expect there's a proper way to do this... 21:16:03 <janders> I haven't done this but I think if 21:16:14 <janders> 1) boot image is smaller than disk and 21:16:31 <janders> 2) cloud-init is configured not to scale up the filesystem 21:16:36 <janders> it might just work 21:17:10 <janders> I remember having a reverse problem with VMs back in the day where resizing fs wasn't done automatically which users were finding annoying 21:17:38 <janders> though i am unsure if fs resize after deploying the image is done by cloud-init (like in VMs) or maybe in ironic instances IPA does that? 21:17:40 <oneswig> Thanks janders, sounds sensible. The issue might be that I end up with a 2G root filesystem (or something crazy like that) 21:18:09 <oneswig> I think the partitioning happens first, and fs resize fills the partition. 21:18:10 <janders> right! valid concern 21:18:19 <oneswig> so I must control the partitioning. 21:18:57 <oneswig> Brings us round to an agenda item 21:19:13 <oneswig> #topic OpenStack Bare Metal SIG - white paper 21:19:35 <oneswig> janders: I think you're already fully signed up to this, right? 21:19:46 <janders> https://bugzilla.redhat.com/show_bug.cgi?id=1355903 21:19:47 <openstack> bugzilla.redhat.com bug 1355903 in diskimage-builder "[RFE] overcloud images have a single partition. Security requirement request for multiple partition options in the RHEL Cloud image" [Urgent,Closed: errata] - Assigned to yroblamo 21:19:58 <janders> this may have some leads on "advanced partitioning" 21:20:11 <janders> I've never used this though, just heard about it doing something similar 21:20:18 <janders> oneswig: yes 21:20:28 <janders> I'm already working on it 21:21:03 <oneswig> Nice - when does it need doing for? 21:21:40 <janders> I wasn't told - though my gut feel is it has something to do with OpenDev in Vancouver (if OpenDev happens that is) 21:23:48 <oneswig> That would make sense. If it gets printed, it would need some weeks before then for layout and so on. 21:24:12 <oneswig> martial: is the bare metal sig something Data Machines is involved in? 21:24:39 <martial> not really 21:25:02 <martial> I am not sure who in the company would be the best POC for it too 21:25:36 <martial> a lot of our work has us do K8s lately 21:26:02 <oneswig> ... but not on bare metal ... 21:26:39 <martial> but not on OpenStack :) 21:26:59 <martial> although we are looking into an undercloud based on OpenStack 21:27:25 <martial> but this is a lot of Ansible scripts to deploy on top 21:27:48 <oneswig> Right, sounds somewhat familiar. 21:28:00 <b1airo> halo! 21:28:08 <oneswig> hey b1airo, g'day 21:28:14 <oneswig> #chair b1airo 21:28:15 <openstack> Current chairs: b1airo martial oneswig 21:28:18 <martial> welcome Blair 21:28:27 <oneswig> How's NZ? 21:28:27 <b1airo> hope you're well! apologies for being late - bouncing between meetings 21:28:32 <b1airo> quiet! 21:28:49 <oneswig> np, we've just been talking bare metal with janders 21:29:01 <b1airo> anything new on that front? 21:29:43 <oneswig> Had a request for participation from the SIG in a bare metal white paper 21:30:20 <oneswig> I'll take the request to the Slack channel later to widen circulation. Looking for user stories and motivations for Ironic 21:31:08 <b1airo> i need to go back to the ISC committee and confirm or not willingness to participate - in one form or another 21:31:11 <oneswig> We've been working recently on a study on the security mitigations for bare metal compute. I'm hoping we can share it as part of this effort. 21:31:39 <oneswig> b1airo: good point, thanks for the reminder. I'm assuming they'll can it, but good to do that anyway. 21:34:08 <oneswig> I'm not sure you can fly anywhere from NZ right now can you? 21:35:34 <b1airo> no, not even if i wanted to ignore my workplace 21:37:25 <martial> honestly not sure if ISC will happen for me either 21:37:51 <oneswig> Seems highly unlikely 21:38:54 <b1airo> yeah my guess would be that it will either move online or won't happen 21:39:19 <b1airo> the question might be whether we'd still want to hold the BoF if they move to an online forum 21:39:33 <janders> allright... I was wondering why it suddenly got so quiet and it was just me getting booted out 21:39:38 <b1airo> seems doable 21:39:43 <oneswig> That seems the likely outcome 21:40:10 <janders> oops seems like I missed a key part 21:40:25 <janders> does it seem like OpenDev will be moved to online format? 21:40:41 <oneswig> I think that already happened 21:41:29 <janders> correct - just read the notification on the website 21:41:41 <janders> good move 21:41:50 <janders> I'd be surprised if ISC20 doesn't follow suit 21:42:19 <oneswig> We were wondering that. 21:42:38 <janders> I don't think anyone from Australia would be able to attend 21:42:42 <martial> last I checked they still had cancelation policy :) 21:42:55 <martial> (ie still happening in person) 21:45:51 <oneswig> Anyone else set up folding@home? There's quite a few people getting on board with that 21:47:55 <martial> for Corona? 21:48:23 <oneswig> yes, apparently 21:50:02 <martial> yes it is sweet ... kind of wish they had alternate CPU versions 21:50:14 <martial> like a Jetson Nano :) 21:50:48 <oneswig> Yes that would be nice! 21:52:23 <martial> and GPU optimized 21:52:38 <b1airo> isn't that what containers are for ? :-P 21:53:14 <martial> not sure if I can run an x86_64 on an arm64 21:55:40 <martial> https://foldingathome.org/alternative-downloads/ 21:55:43 <martial> nope 21:57:24 <oneswig> Nearly at the hour folks 21:57:31 <martial> https://www.irccloud.com/pastebin/Sq2eDVc5/ 21:57:45 <martial> (sorry) 21:57:49 <martial> that on the other hand is interesting "The Folding@home team know about the work unit shortage. 21:57:49 <martial> It's happening because of an approximately 20x increase in demand." 21:58:19 <janders> stay safe - and we'll chat again next week 21:58:41 <oneswig> Same to you! 21:59:07 <martial> bye :) 21:59:21 <oneswig> until next time 21:59:24 <oneswig> #endmeeting
