mattoliverauo/07:01
diablo_rojoHow was your weekend?07:01
* diablo_rojo makes small talk while waiting for others to show07:01
mattoliverauahh, good07:02
diablo_rojoAll ready for baby #2?07:02
*** apetrich has joined #openstack-meeting07:02
mattoliverauCould have the baby any day now, so good but  just always making sure everything is ready.07:03
diablo_rojoExciting :)07:03
mattoliveraugot some new furniture delviered, so build that (ikea!)07:03
diablo_rojoGotta love Ikea07:03
mattoliverauand now have to find time to finish some painting07:03
mattoliverautrying to do things because as soon as baby comes everything will be on hold for quite a while /me thinks07:04
diablo_rojoYeah that makes sense.07:04
mattoliveraualso the wife is in nesting stage so everything has to be ready and just right or she can't relax07:04
diablo_rojoHormones are funny.07:04
diablo_rojoMethinks its just going to be the two of us this week..07:05
mattoliveraulol, yeah. The wife knows it just the hormones so we do laugh about it07:05
mattoliveraueveryone else might have forgotten07:05
mattoliverauwas gmann still visiting india?07:05
diablo_rojoI know cmurphy|vacation is in Greece from what I have seen on her instragram. I think tonyb said he had a meeting when we discussed the neww time/rotation last week.07:05
mattoliverauor should he be back07:06
diablo_rojoNot sure when he was supposed to be back.07:06
mattoliverauwell, lets just get going then :)07:06
diablo_rojoW can quickly go through things and call it early.07:06
mattoliverauyup07:06
diablo_rojo#link https://wiki.openstack.org/wiki/First_Contact_SIG#Meeting_Agenda07:06
diablo_rojo#topic New Contributor patches07:06
*** openstack changes topic to "New Contributor patches (Meeting topic: fc_sig)"07:06
diablo_rojoI actually looked at a few07:07
diablo_rojoand poked some people about some07:07
mattoliveraunice!07:07
diablo_rojoNothing really new to report. There were a few new contributors I noticed that I linked to further down in the Agenda that we should probably reach out to.07:07
mattoliverauI was going to say I've been meaning to look at them today, like I always seem to do (last minute) however time got away from me today :(07:07
diablo_rojoSeems they are fixing spelling things all over the place.07:08
mattoliveraucool cool07:08
diablo_rojoMight want to reach out and help them settle in somewhere.07:08
mattoliveraugood idea, I've seen a bunch from inspur lately, that's awesome07:08
diablo_rojo#link https://review.openstack.org/#/c/592228/ Person to reach out to07:09
diablo_rojoYeah that is awesome.07:09
diablo_rojoSeen a few other new names here and there.07:09
diablo_rojoThere was one girl on the dev list Ivoline?07:09
diablo_rojoShe and I emailed back and forth a bit.07:09
diablo_rojoShe's interested in Sahara.07:09
mattoliverauI remember reading that, thanks to responding back to her07:10
diablo_rojoThe patch I linked was from an Inspur guy07:10
diablo_rojoDid you wanna reach out to them?07:10
* tonyb foudn a new contributor for stable branches but I think the fire has gone out on that review :(07:10
tonybsorry I'm late :(07:10
diablo_rojoOh hello tonyb :)07:10
mattoliverauhey tonyb o/07:10
diablo_rojoNo worries.07:10
diablo_rojoPerhaps I should have talked about t-shirts to make you show up faster ;)07:11
* tonyb wasn't waiting in the wrong channel ... nope that was some other tonyb07:11
mattoliverauyeah, I'll reach out to them. I think I've seen some inspur patches in swift too07:11
mattoliveraulol07:11
diablo_rojomattoliverau, I imagine its the same type of patch that they are doing all over the place.07:11
mattoliverauyeah, /me thinks so to. But if there looking and going to effort of submitting patches lets try and focus them :)07:12
diablo_rojoMy thoughts exactly.07:12
diablo_rojo#action mattoliverau will reach out to some of the newer inspur contributors07:13
diablo_rojoIts on the record now.07:13
mattoliveraudamn^w awesome :P07:13
tonyb:D07:13
*** longkb has quit IRC07:14
*** r-mibu has joined #openstack-meeting07:14
diablo_rojoOkay onto the next topic?07:14
mattoliverauI don't have anything else, shall me move on?07:14
mattoliverauyes07:14
diablo_rojo#topic Ask.o.o07:14
*** openstack changes topic to "Ask.o.o (Meeting topic: fc_sig)"07:14
diablo_rojoI did not do this part of the homework..07:15
mattoliverauLast week I linked up more of the tags to search links07:15
diablo_rojoYeah it looks like there are a few new tags07:15
diablo_rojoI will try to get to those tomorrow07:15
mattoliverauunfortuanly ask.o.o when adding tags according to something I read (I forget where) always uses AND to join them instead of OR. so lots of links rather then 107:16
diablo_rojoThere was a conversation a while back with jamesmcarthur about adding some other to our list, but never heard back from him on that.07:16
diablo_rojoThats super annoying07:16
*** takamatsu has quit IRC07:16
diablo_rojoThis works though.07:16
mattoliverauLol, I just clicked on a link and can seem to access ask.o.o atm.07:17
diablo_rojoSomewhere I made an etherpad to populate ask.o.o but I don't have it on the agenda for some reason07:17
mattoliverauI didn't do my homework this week, but did check last wednesday and at that time there was nothing new to report07:17
diablo_rojoAs we've learned, not much changes week to week.07:18
diablo_rojoI found it!07:18
diablo_rojo#link https://etherpad.openstack.org/p/ask.o.o-contribution Etherpad for seeding Ask.o.o07:18
*** ykatabam has quit IRC07:18
* diablo_rojo updates agenda with url07:18
mattoliverausure, but if we don't check it one week.. .thats when something happens :P07:18
diablo_rojoAlso true07:19
mattoliveraunice, full of seeds :P07:19
diablo_rojoCurrently empty but, I made the etherpad. .07:20
diablo_rojoOne step in the right direction.07:20
*** electrofelix has joined #openstack-meeting07:20
mattoliverau+107:20
diablo_rojoI should just go through and ask a question for each section of the contributor guide.07:20
diablo_rojoMaybe if I get bored tomorrow/thursday I will throw some things in there.07:20
diablo_rojoAnything else on this topic?07:20
mattoliveraubit a bad idea :)07:20
mattoliverau*not07:21
mattoliveraunope07:21

diablo_rojoOkay moving on then.07:21

mattoliverau:(07:22
diablo_rojoI see that. Thank you mattoliverau :)07:22
mattoliveraubut I added stuff for you all to talk about, your welcome :P07:22
*** jesusaur has quit IRC07:23
diablo_rojoThinking it might just be a half day this go around instead of a whole day.07:23
diablo_rojoWe'll see what other things get added.07:23
mattoliverauThe ops summit is at the same time and same place, so might be a good time to try and connect with them07:23
mattoliverausure07:23
diablo_rojomattoliverau, yeah I wanna try to drop into their room07:23
diablo_rojoMaybe even invade their agenda for a few minutes with mention of us/contributor guide/portal07:24
mattoliverauit might be better trying to sit in and hallway track to catch any new contributors walking around07:24
diablo_rojoI'll have to see if I can find their etherpad07:24
mattoliverauI mean the general PTG sessions07:24
mattoliverauso 1/2 day for FC SIG is fine and then hallway track talking to people, especally first/new people to the PTG07:25
diablo_rojoYeah I have a few other things I have to do during some of that but to fill in the rest of the time.07:25
tonybhttps://etherpad.openstack.org/p/ops-meetup-ptg-denver-2018 ?07:25
mattoliverauyeah, your alwasy really busy. Sorry I wont be there07:25
diablo_rojoooOOOoo thank you tonyb :)07:26
diablo_rojoThat's the one I think I need.07:26
diablo_rojomattoliverau, never bored that's for sure :)07:26
tonybit hits all the buzz words07:26
mattoliveraulol,07:26
tonybdiablo_rojo: "17:20 < diablo_rojo> Maybe if I get bored" ... so that means never to that thing then ;P07:27
*** jesusaur has joined #openstack-meeting07:27
mattoliverau:P07:27
diablo_rojotonyb, Bored at events vs bored with sending emails (aka 75% of may days lately)07:28
tonybdiablo_rojo: fair enough /me will be nice now ;P07:28
diablo_rojoAnywho, if either of you come up with more topics we should talk about please add them.07:29
tonybwill do07:29
diablo_rojotonyb, I suppose we're even for my swag shirt comment earlier :)07:29
mattoliveraukk07:29
* diablo_rojo holds better quips for later07:29
diablo_rojo#topic Berlin Planning07:29
*** openstack changes topic to "Berlin Planning (Meeting topic: fc_sig)"07:29
diablo_rojo#link https://etherpad.openstack.org/p/FC_SIG_BER_Planning Berlin Planning Etherpad07:30
mattoliverauI made an etherpad for this, but really it may depend on what is talked about and how the PTG goes. maybe some follow ups07:30
mattoliveraubut good to have it there for topics07:30
diablo_rojoYeah I dunno how many original topics we will have for forum sessions persay.07:30
diablo_rojoFollowing up on the Organisations contributing to OpenStack one maybe07:31
diablo_rojoOutside of that...not sure what else we have other than making people aware that we are a thing. Maybe just a meet & greet hang out. Come find us and ask questions.07:31
mattoliverauyeah, proabably, time will tell07:31
mattoliverauoh meet and greet (and drink?) might be fun07:32
tonybYeah I'm not sure we have any new topics fro the forum but a meet and greet could work07:32
diablo_rojoI dunno. PTG is the focus ATM, forum session proposals won't open till the PTG. So we have some time to stew on them.07:32
diablo_rojoI think that would be good. Similar to the Project Onboarding rooms, but for people that don't even know what project they want to get in on.07:33
mattoliverau+107:33
tonyb+107:33
tonybif that were a thing I'd be there07:33
diablo_rojoWorse comes to worse, we just play Coup or Loveletter or Nuts or something :)07:34
diablo_rojoAnything else on Berlin planning?07:34
mattoliverau+10007:34

mattoliverauLast week a pushed up a new patchset07:35
diablo_rojo#link https://review.openstack.org/#/c/578676/ Patch07:35
mattoliveraudiablo_rojo: thanks for the review07:35
diablo_rojomattoliverau, I saw :) I think I had 4ish small comments07:35
diablo_rojonothing really worth -1ing for07:36
diablo_rojoZuul was upset about pep8 though07:36
mattoliverauwell we really need to work on padding it out.07:36
diablo_rojoI think we should bring it to the TC's attention if we want more ideas/comments07:36
mattoliverauI forgot to go ask persia if what I remember him offering as the truth, I'll do that this week for sure :)07:36
tonyb;P07:37
mattoliverauyeah getting good wordsmiths involved would be good.07:37
mattoliverauTC would be great07:37
diablo_rojoI think he was added as a reviewer07:37
diablo_rojoBut yeah reaching out directly might work better07:37
diablo_rojoWell there are TC office hours in 5 hours if someone wants to be there for that.07:38
diablo_rojoOtherwise I can try to remember to bring it up next tuesday07:38
diablo_rojoOr we just email their ML07:38
*** longkb has joined #openstack-meeting07:39
diablo_rojoSo many options07:39
mattoliverauIf my brain is still working at that time and I remember I'll pop in.07:39
mattoliveraubut don't hold your breath :P07:39
tonybjust email os-dev the tc list isn't very helpful 'cause of moderation07:39
tonybthe next office hours would be good as the late tueady one isn't very popular ;/07:39
diablo_rojomattoliverau, I won't hold my breath as I will be sleeping ;)07:39
tonybbut Ican bring it up there if you like07:40
diablo_rojotonyb, which place? ML or office hours?07:40
diablo_rojoOr both? :)07:41
tonybdiablo_rojo: the office hours, late Tueady next week as that's in the middle of my day07:41
*** fdegir has joined #openstack-meeting07:41
diablo_rojotonyb, Got it. Yeah that would be great :)07:41
tonybdiablo_rojo: cool07:42

diablo_rojo#action tonyb to bring up mattoliverau's patch with the TC during office hours next week07:43

oneswigI was thinking, to follow up on discussion in Dublin, I ought to get together a write-up of our experience with Cinder boot-from-volume11:08
oneswiglimited success so far but I think it worked in a basic case for networking and cinder configuration.11:09
martialand the Scientific content SIG info is at11:09
martial#link https://etherpad.openstack.org/p/scientific-sig-denverptg201811:09
jandersI'd chip in some thoughts on ironic resiliency enhancements11:10
oneswigOne big thing that went by recently was the Ironic gang proposing work on boot from (ceph) volume.  Which we'd really love11:10
oneswigI'll add my bit too11:10
jandersI've had some networking issues probably not worth mentioning in detail here - long story short when one node gets stuck in "deploying" ironic dies till conductor is restarted11:11
jandersThere's a BZ for that, I'll try look it up11:11
priteauwow, I have never seen this bug11:11
priteauIs it happening on a specific release?11:12
oneswigSounds nasty janders, not seen that ourselves and plenty of things can go wrong ...11:12
jandersThere are two, actually11:12
jandersQueens11:12
janders1) the thing just described11:13
janders2) when nova compute gets started before keystone is responsive, it'll go deleting placement records11:13
jandersThese are private BZs, let me chat to RHAT to see how to best go about this11:14
oneswigAh, perhaps something will appear on storyboard if they get to commit a patch11:14
*** electrofelix has joined #openstack-meeting11:14
oneswigWe have ~500 Ironic nodes on a Queens deployment.  The infrastructure's second hand so things do get flakey at times but I'm not sure we've hit these specific issues.11:15

oneswighi daveholland, well done for making it through11:17
priteaujanders: what is deleted in placement exactly? On Ocata we've seen issues were new compute nodes entries are created, which don't match existing resource providers in placement11:17
*** d0ugal has joined #openstack-meeting11:17
oneswigdaveholland: I had a question for you about networking VRFs, perhaps in AOB...11:19
oneswigdon't let me forget11:19
janderspriteau: records for ironic nodes disappear. It manifests itself when instances don't get scheduled to ironic nodes anymore.11:19
martialfeel free to add it to the etherpad, who knows maybe somebody has some idea :)11:19
davehollandoneswig: sure (networking not my strong point but I can pass questions on)11:19
*** ttsiouts has joined #openstack-meeting11:20
oneswigdaveholland: simple question was, what consumes 1 VRF on the TOR switch?  Is 1 VRF required for every VXLAN VNI?11:20
jandersoneswig: do you have any experience running vxlan over IB?11:21
davehollandoneswig: I don't believe so but I will check11:22
oneswigjanders: no, sorry.  Isn't pkeys your best bet there for VTN segregation?11:22
oneswigSaw a great talk on it at the summit :-)11:22
jandersoneswig: :) pkeys are cool for baremetals and sriov vms11:23
jandersI'm trying to see if I can squeeze in some vanilla virtualised Ethernet nics on my SuperCloud instead of building a separate one11:24
oneswigOK, we've got a little off topic... was there any more on the PTG?  For those of us not going, anything we'd like to see pursued from the OpenStack devs who will be attending?11:24
davehollandoneswig: Jono says that you only consume VRFs for hardware routing for tenant networks (which we're not currently doing) (to a max of 2047 VRFs on these switches... but you can scale-out)11:24
oneswigjanders: a question of multiple physnets?11:24
jandersFrom my side I'll chat to rhat on how to best chase up these resiliency issues. Already sent them a note.11:25
oneswigthanks janders, would be very helpful11:25
oneswigthanks daveholland - and Jono - so this is specifically for routing between VXLAN overlay networks?11:25
jandersoneswig: Is it possible to specify sdn controller on per physnet basis?11:26
davehollandyes, but only when you go to hardware routing or distributed routing (DVR)11:26
oneswigjanders: I believe so, we use a mix of Mellanox IB and networking-generic-switch on multiple deployments11:26
jandersGreat! Thanks heaps oneswig:11:27

jandersThe solution is getting quite solid now11:56
jandersI hope for solid POC with users on by the end of the year11:56
jandersAnd continuous delivery from there11:56
oneswigjanders: sounds good.  Are you doing a containerised tripleo deployment?11:57
jandersMost ppl would probably call that prod but I like to play things safe11:57

*** slaweq has joined #openstack-meeting16:15
jungleboyjDo we have eharney here?16:16
jungleboyjjbernard is not.  He could also help with this question.16:16
eharneyhi16:16
cmartvery short version: many of my servers are 'pets' running non-cloud-native workloads. I run them as volume-backed instances, and use Cinder backup service to take volume backups of them every day16:16
cmartall is good until I want to start pruning old backups. (backend here is Ceph RBD)16:17
cmartit seems that Cinder Backup Service + Ceph RBD = you can only delete the *latest* backup of a given volume16:17
cmartwhich makes it basically impossible to manage recurring backups in a reasonable way16:17
cmartand it seems this limitation is not inherent to Ceph backend, so I'm not sure why Cinder imposes it16:18
cmartwas hoping to connect with people who are either:16:18
eharneyyeah, i think this is a limitation of cinder backup with how it can manage chains of incremental backups, and not really a Ceph issue16:18
cmart 1. taking recurring volume backups like I am, and may have advice/experience to share16:18
jungleboyje0ne:  Have you bumped into this with the work you have done on backups?16:19
cmart2. familiar with this architecture in Cinder, and could help me understand and maybe I can help work on a fix16:19
eharneyiirc cinder backup doesn't provide what would be needed for an "incremental forever" kind of back up strategy, i think it assumes you will regularly create full backups, but i haven't looked at this in depth in a bit16:20
jungleboyjCould you resolve the issue by doing full backups instead of incremental?16:20
cmartI would if I could16:20
e0nejungleboyj: I didn't face this issue, but I agree with eharney16:20
cmartCinder ignores the `--incremental` flag when you create backups with Ceph RBD backend.16:20
cmartthe first backup of a given volume is *always* a full backup, and each subsequent backup is *always* an incremental backup.16:20
jungleboyjHmmm, ok.  Good to know.16:21
*** slaweq has quit IRC16:21
e0necmart: it could be an issue with ceph driver if it ignores 'incremental' flag16:21
eharneyisn't the inability to delete older backups an api-layer restriction?16:22
smcginnisThat sounds like a ceph bug actially.16:22
smcginnis*actually16:22
jungleboyje0ne:  Yeah, that sounds buggy.16:22
cmarte0ne and eharney: yes and yes16:22
*** finix has quit IRC16:22
*** cloudrancher has quit IRC16:22
smcginnisAny backup program behaves this way if you only ever do incremental backups.16:22
smcginnisBut you need to be able to create full backups from time to time at least or incremental really becomes useless.16:23
cmartsmcginnis the nomenclature is loosely applied here -- I believe that Cinder "incremental" backups with Ceph RBD are really *differential* backups16:23
jungleboyjsmcginnis:  ++16:23
eharneythis is solved in some backup software by synthesizing new full backups out of a chain of incremental backups periodically (which you need to do anyway if you want to be able to restore in a reasonable amount of time)16:23
eharneyhrmm, i forgot about that terminology detail16:24
smcginnisIf Cinder itself doesn't allow full backups, then that's a bug in cinder. If Ceph doesn't ignores it and only does incremental or differential, that's a bug in that dirver.16:24
jungleboyjsmcginnis:  ++  I think that is where we need to start.16:24
jungleboyjcmart:  If we are able to resolve the inability to ever create a new full backup would that help resolve your issues?16:25
cmartyes, I think so, if then Cinder allows deletion of old full / "incremental" backups before the newer full backup.16:26
smcginnisThat's how it should work.16:26
cmarton the backend, interestingly, "incremental" backups are stored as snapshots of the RBD image, meaning they don't depend on each other16:27
eharneyhow backups are stored on the ceph backend is a bit confusing compared to how they are represented in cinder -- but some of that is a feature, not necessarily a bug16:27
cmartyeah. each "incremental" backup (according to cinder) actually contains a complete diff from the base in Ceph. so it's kinda standalone16:27
eharneyso we need to be clear about what exactly we're trying to sort out here16:27
e0neeharney: +116:28
cmartyeah. I think a straightforward solution would be if the `--incremental` flag was respected16:28
cmartI'm not really familiar with the existing code but happy to try to help16:29
jungleboyjcmart: ++ I think that makes sense.16:29
eharneywith the goal being that if you didn't supply that flag, you would end up with a fully independent new backup, which is not based on the older previous backups, right?16:29
cmartcorrect, eharney16:30
jungleboyjeharney:  ++16:30
eharneyso, that's one possible solution, another would be to add something to break the dependency chain when you are performing the delete, to preserve the space optimization etc16:30
eharneybut regardless of how it gets fixed it sounds like an interesting thing to look into16:30
smcginnisWell, the first is how it should work, but the second may be useful in some cases.16:30
smcginnisBut a little odd as far as backup software behavior goes.16:31
cmartas to your last point eharney, Cinder would need a new concept of "differential" backup (as opposed to incremental)16:31
eharneybut we only define how it should work in terms of what data is backed up and restoreable and how it behaves from the Cinder API layer16:31
eharneythis driver does some optimizations in the backend to avoid transferring more data than is needed, which is fine as long as the right semantics are preserved at the higher layer16:31
smcginnis++16:32
eharneyso i guess the other question is, can you actually prune old backups when using other drivers?16:32
jungleboyjeharney:  ++16:32
cmartmy only experience here is with RBD16:33
jungleboyjI don't think we want to create a special case.16:33
eharneysounds like it's worth writing a bug about for more investigation16:33
xyangSorry that I may have missed some of the earlier discussions.  If I remember correctly, Ceph backup driver implemented its own way of incremental backup, not using Cinder's incremental backup16:34
xyangSo Ceph added support to incremental backup to ceph volumes, even before we added incremental backup support to Cinder16:34
eharneyit still works with incremental backups in cinder, and tracks parent ids, etc16:34
*** slaweq has joined #openstack-meeting16:35
eharney(at least it's supposed to, it was kind of a mess a while ago but got a lot of bug fixes a couple of cycles ago)16:35
xyangbut Ceph driver does not inherit from the chunked driver mechanism16:35
smcginnisLet's get a bug filed and verify that things are working correctly for all of them or if this is just an issue with ceph.16:35
xyangunless if someone has changed that16:35
eharneythat's true, but i don't think it's really relevant?16:35
jungleboyjsmcginnis:  ++16:35
smcginnisYeah, chunked shouldn't matter, should it?16:36
smcginnisThat's just how the data gets transferred.16:36
xyangyes, it does matter16:36
xyangCeph has its own way of doing incremental16:36
eharneyif that matters then we messed up somewhere, because that's just an implementation of how to keep track of the blocks of data16:36
xyangso you need to take a look of that driver16:36
xyangunless if someone re-write that to use cinder's incremental backup model16:36
xyangI thought Gorka may be familiar with this16:37
cmartI was hoping he might be around16:37
cmartthis is a bit old https://gorka.eguileor.com/inside-cinders-incremental-backup/#Ceph-Incremental-Backup but maybe still relevant16:37
jungleboyjSo, I have a proposal ...16:37
xyangcmart: I think you should check with Gorka about this16:37
jungleboyjLets get a bug opened for this.  Gorka and the important players will be in Denver.16:38
jungleboyjIf we can get geguileo aware of the issue and then we talk it over at the PTG we can figure out where to go.16:38
cmart+1 I'll file a bug, and reference the questions asked here.16:38
smcginniscmart: Thanks!16:38
geguileojungleboyj: sorry, forgot about the meeting (I miss the ping)16:39
jungleboyjgeguileo: Sorry.16:39
jungleboyjI just can't get booted every week.  ;-)16:39
*** psachin has joined #openstack-meeting16:39
geguileolol16:40
geguileoI was catching up16:40
geguileoSo this is an issue with the backups being linked when incremental, right?16:40
geguileoThey want to remove that?16:40
xyangcmart: just checked.  Ceph backup driver is still not using Chunked driver16:41
smcginnisgeguileo: Basically, after a new full backup, you should be able to delete previous backups.16:41
geguileoxyang: we don't use it because it's faster to ask Ceph cluster to get us the diff16:41
smcginnisgeguileo: It doesn't look like that's possible, at least with the way ceph is implementing things.16:41
xyanggeguileo: not a problem.  trying to differentiate Ceph's implementation vs Cinder's incremental16:41
geguileosmcginnis: yup, we have to start checking the parameter passed by Cinder16:41
geguileoI don't think we do it right now16:41
smcginnisAh, good. Not that it doesn't work now, but that it is something simple like that.16:42
geguileoI would have to check how easy it is to do16:42
geguileoBecause I believe Ceph does it always incremental if it can16:42
geguileoregardless of the parameters passed to Cinder16:42
cmartgeguileo yes that's my experience16:42
cmartit's great until you want to remove old backups while keeping newer ones16:43
jungleboyjOk, so it sounds like we have a bug that needs to be investigated.16:43
cmart(I think pretty much everyone doing recurring daily backups will want to do that)16:43
cmartgot it. thanks for the context, all :)16:43
geguileojungleboyj: yup16:43
e0nejungleboyj: +116:43
geguileothe bug is that Ceph cannot create full backups after the first full backup16:43
jungleboyjgeguileo:  ++16:44
jungleboyjgeguileo:  Are you able to look into that?16:44
geguileojungleboyj: I can at least look to see if it's an easy fix16:45
geguileolol16:45
jungleboyjgeguileo:  I will take that.16:45
geguileocmart: is there a bug open?16:45
jungleboyjgeguileo:  If not we can talk about it more at the PTG?16:45
cmartgeguileo not yet but i'll summarize the above ^ and write one up for you16:45
jungleboyjcmart:  That would be great.16:45
jungleboyj#action cmart to open a bug summarizing the issue.16:46
jungleboyj#action geguileo To look into it and see how hard it would be to change.16:46
geguileocmart: thanks!16:46
jungleboyjcmart:  Thanks for bringing this up!16:46
cmartof course. thanks for accommodating my use case16:47
jungleboyjcmart:  Sounds like a totally valid one.  :-)16:47
jungleboyjcmart:  Anything else?16:47
cmartthat's all for now jungleboyj16:48

jungleboyj#topic Cross Project Times Added for PTG16:48
*** openstack changes topic to "Cross Project Times Added for PTG (Meeting topic: Cinder)"16:48
jungleboyjSo, we have time at the PTG planned 4-5 on Wednesday to chat with Ironic.16:48
*** slaweq has quit IRC16:49
jungleboyjJulia contacted me and asked if we had any topics for her.  I didn't know that we did but thought discussion about what Ironic is doing with Cinder and what they are planning to do in the future could be useful.16:49
*** yamahata has quit IRC16:50
jungleboyjIf you have specific topics for that time please add them to the etherpad and mark them accordingly.16:50
jungleboyjAlso, we have our traditional 9 to 11 am time on Thursday with Nova.16:50
jungleboyjIf you have anything to discuss with Nova please add the topic and I will schedule it for the cross project time.16:50
jungleboyjAnyone have anything else to share there?16:51
e0neWednesday will be great for me. that's great if we get full support of boot from volume and attach for ironic instances16:52
jungleboyje0ne: Cool.  Glad that will be useful time.16:52
jungleboyjI figured if we got the teams together something useful could come from it.  :-)16:52
geguileojungleboyj: I added something to Nova16:53
