21:00:33 <trandles> O/
21:00:43 <martial> hello everybody :)
21:00:50 <oneswig> #chair martial
21:00:51 <openstack> Current chairs: martial oneswig
21:01:22 <oneswig> What's new?
21:02:20 <oneswig> I've been working on some follow-up for this project
21:02:34 <oneswig> #link federated Ceph for the Euclid space telescope https://indico.cern.ch/event/765214/contributions/3517141/attachments/1908894/3153554/2019-09-17-TelferGarbutt-Ad-hoc-Filesystems.pdf
21:03:00 <oneswig> Turns out our Ceph deployment is not at all balanced in its data distribution
21:03:15 <trandles> I'm kinda here for the meeting but might get interrupted...so my one question is for martial. Is everything sorted for the SC19 BoF? I'll be there on a full technical pass this year.
21:03:18 <oneswig> had OSD occupancy ranging ~1% - ~94%
21:03:57 <oneswig> trandles: thanks for the reminder, had forgotten to buy a ticket, better put that on the list...
21:04:23 <martial> you know, I need to do that too :)
21:06:57 <oneswig> trandles: do you get your money's worth from the full pass?
21:07:08 <trandles> martial: we don't need to submit a revised proposal or anything?
21:07:16 <martial> trandles: I ned to confirm attendance but beyond that I believe we have everything needed
21:07:19 <trandles> oneswig: yeah, I'll be able to attend all the talks I like
21:07:46 <trandles> Usually I'm on exhibitor and can't do anything but attend meetings and stay in the exhibit hall :(
21:08:19 <oneswig> trandles: I only went to SC16 previously and I think that's what I had too.
21:11:23 <martial> oneswig: so what about that OSD? :)
21:12:20 <oneswig> ha.  I'm working hard to get this cluster reweighted to the point where it resembles balance.  Still nowhere near.
21:13:05 <oneswig> I wonder if there's a way in Ceph to establish how big each PG is, some of these ones do seem quite chunky.
21:13:58 <oneswig> Got another interesting problem, in that the MDS has halted processing CephFS, possibly due to nearfull OSDs (hopefully - because that's something I can fix)
21:14:19 <oneswig> The MDS claims to be "behind on trimming" and ballooning in memory
21:15:57 <oneswig> still working on that bit.  I was hoping jomlowe would have some wise words on it...
21:16:35 <martial> was hoping to ask Cloud Federation question with jmlowe as well
21:17:53 <oneswig> martial: what's up there?
21:18:46 <martial> mostly about metadata exchange solutions
21:19:02 <martial> and understand how xseed does it
21:21:42 <oneswig> Mike and Bob Budden gave a talk once on a way of using IIRC Murano to share application images between clouds...
21:24:23 <martial> might ask that of them next time I see them
21:24:40 <oneswig> OK, I think I need to shut down for the night... anything more to raise?
21:24:54 <martial> all good on my end
21:24:58 <trandles> rbudden: PING! You're being talked about
21:25:12 <oneswig> ha, IRC ears are burning
21:25:41 <oneswig> OK I'm going to head off before he notices and corrects my slanders! :-)
21:25:42 <trandles> I have nothing. Been working on Ironic stuff. We should have our new cloud engineer starting very soon. Hope to have some new developments to discuss in Denver.
21:25:59 <oneswig> trandles: good to hear you filled the post
21:26:08 <oneswig> Should be an exciting role, no doubt!
21:26:15 <martial> cool :)
21:26:20 <trandles> Fingers crossed it goes to plan
21:27:02 <oneswig> btw trandles: am somewhat proud of this recent work on Ironic https://www.stackhpc.com/bespoke-bare-metal.html
21:27:37 <trandles> Thx for the link, I'll read up
21:28:06 <oneswig> excellent.  Until next time y'all
