esbergluThat's all from my end13:02
esbergluOh yeah and slowly knocking out doc updates13:03
esbergluAnything else?13:04
efriedMight want to push mriedem to approve our spec.13:05

esbergluAnything to discuss here?13:09
edmondswand iscsi..13:10
edmondswtaylor is working on both, with patches up13:11
efriedresize attached volumes?13:11
edmondswI've given some comments on the iscsi pypowervm changes that he needs to resolve first, but I think we're closing in on that13:11
edmondswand Gerald has also looked at that, which is good13:11
edmondswI don't think Gerald has looked at the ceph changes yet, which I need to ping him about again13:11
edmondswefried what about resize attached volumes?13:12
efriedIt's out there, looks like it's getting reviews.  Also a tjakobs thing.13:12
efriedI'm just listing open stuff in nova-powervm13:12
edmondswk, it sounds familiar but I don't know if I've reviewed it yet or not13:13
edmondswI'll look for it after this13:13
edmondswI think the force resize work merged, right?13:13
edmondswwe should talk about the new request that thorst mentioned yesterday13:14
edmondswhost-level CPU util metrics ported down to pypowervm13:15
edmondswanybody want to take that?13:15
efriedI nominate anyone with an 8-char nick starting with 'e'.13:16
edmondswefried not just anyone starting with "e" ?13:16
efrieddefinitely not13:16
edmondswpretty much what I figured, we're all busy... I'll throw it on the todo list13:17
edmondswtry to get to it if I can13:17
edmondswthat's probably all for OOT right now13:17
esberglu#topic Device Passthrough13:17
*** openstack changes topic to "Device Passthrough (Meeting topic: powervm_driver_meeting)"13:17
edmondswefried you up13:19
efriedOOT, no progress13:19
efriedIT, been keeping a close eye on placement specs13:19
efriedThat's about it.13:20
edmondswefried it would be good if you could glance at the cyborg stuff and how that fits in13:20
edmondswI think I sent you a link about that the other day? If not, I'll go find it again13:21
edmondswmdrabe have you been able to spend time on this since you got back?13:21
mdrabeOnly a little bit13:22
efriedI have these links: https://wiki.openstack.org/wiki/Cyborg https://review.openstack.org/#/c/448228/13:22
efriedIf nova doesn't call out to cyborg, how could it help us?13:23
edmondswin boston it was very unclear how cyborg would fit into the picture. They were still very much trying to figure that out themselves13:23
edmondswif that has started to gel at all now, and I've gotten the impression it has, we need to know how that is going to work13:24
edmondswand then we can answer your question :)13:24
efriedI'll read up.13:24
edmondswmdrabe I'll ping you offline and we can talk about that13:25
edmondswesberglu I think that's all here for now13:25

*** openstack changes topic to "PowerVM CI (Meeting topic: powervm_driver_meeting)"13:25
esbergluI ended up just reinstalling that whole problem SSP group last night13:26
esbergluThe image template just finished building, ready nodes are spawning now13:26
esbergluSo it should be back up within the hour13:26
esbergluNothing else to report13:27

edmondswk, tx13:27
efriedesberglu No love from Veena or Uma?13:27
esbergluVeena helped for a little bit, but the problem wasn't obvious. She said I could wait until today or just reinstall13:27
esbergluI'll post here when it's back online13:28

edmondswefried here's another link for cyborg: https://etherpad.openstack.org/p/cyborg-queens-ptg13:29
edmondswsee the notes section there13:29
efriedesberglu Did you force-wipe the SSP disks?13:30
efriedCause if you didn't, and the problem is in the cluster metadata, reinstalling the systems ain't gonna do you much good.13:30
esbergluI created new ones13:30

efriedesberglu Bah, the "TODO(efried): CONF these" was intentional"20:48
efriedAs in, I didn't want to have conf options at all yet.20:49
esbergluefried: I can pull it back out. Why not?20:49
efriedThe defaults were fine; makes the change sets smaller; reduces our footprint; simplifies the UX...20:49
efriedBasically, we're trying to avoid putting in conf options if we possibly can.20:50
efriedHence the "maybe".20:50
esbergluefried: Got it. Will do20:50

edmondswefried do you know the history of why those conf options were created in nova-powervm?21:25
edmondswjust overkill?21:26
efriededmondsw With the OOT driver, we just created 'em whenever we felt like one was possible - we weren't deliberately trying to be conservative.21:26
efriedIt's different in tree21:26
efriedWe'd be adding conf options to nova itself.21:26
edmondswI'm wondering if we should go pull them from the OOT driver... would like them to be consistent21:27
efriedWe can discuss with thorst at some point, but I'm gonna say nah.21:27
edmondswif there's no good argument for them to be in nova, there's no good argument for them to be OOT21:27
edmondswunless it's "we'd like to do them in nova at some point, but not today"21:28
efriedMore like, "We might someday do them in nova, if anyone asks for them and we can't talk them out of it."21:28
efriedBut at this point, deprecating/removing OOT would be more trouble than it's worth.21:28
efriedWe'll eventually need e.g. for selecting disk drivers (assuming we decide we want to support more than one of those)21:29
edmondswdoes nova really care if we add conf options as long as they're in our own group? I think all the other drivers have some21:30
edmondswefried ^21:31
edmondswnot that I want us to have a whole ton of options...21:32
efriedProbably not a lot.  But I care.  Yeah.21:32
efriedIf we run across something that really doesn't have a reasonable default that works 99.9% of the time, or if someone asks for something and makes a good case for it, that's fine.  But in general, I want to KISS.21:33
edmondswI agree with that. Wish we'd followed that OOT...21:33
