21:00:49 <openstack> The meeting name has been set to 'scientific_sig'
21:00:57 <oneswig> ahoy
21:01:57 <janders> g'day Oneswig
21:02:12 <oneswig> Hey janders, what's new?
21:02:16 <oneswig> all well here
21:02:42 <martial> okay so super confused ... the meeting was one hour ... did you guys just change DST again? :)
21:03:15 <oneswig> oh man, what happened?
21:03:33 <oneswig> My calendar (I think) is set in UTC...
21:03:43 <janders> doing okay.. we're not far from being under house arrest here in AUS
21:03:56 <janders> pulling my hair out trying to get some groceries online
21:04:21 <oneswig> #chair martial
21:04:22 <openstack> Current chairs: martial oneswig
21:05:38 <martial> yeah VA is "if you are not shopping or working stay home" (wear a mask if you are out ... nowhere to be found of course)
21:05:49 <oneswig> yes, unusual times.  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
