zigoE: cinder source: source-is-missing api-ref/v1/source/_static/bootstrap.min.js08:23
zigoCinder is now non-free.08:23
zigoCould someone address this, and replace the javascript blob by a free software version?08:24
*** salv-orl_ has quit IRC08:25
*** itzdilip has joined #openstack-cinder08:25
dulekzigo: There is a line about MIT license in that file. What exactly would you expect there?08:26
* dulek isn't really keen on software licensing… :(08:26
zigodulek: I expect people to remember that we *cannot* include pre-compiled javascript blobs like this one: we must include the non-minified version.08:26
zigoIt's only the 100th time I repeat it... :P08:26
zigoIt's like if we were shipping a .so or a windows .dll pre-compiled without its corresponding source code.08:27
*** nkrinner has joined #openstack-cinder08:27
dulekzigo: Same goes for bootstrap.min.css?08:28
zigoFor everything.08:28
duleksheel: Are you online maybe?08:28
sheeldulek: yep08:29
sheeldulek: tell me08:29
duleksheel: Please read my conversation with zigo.08:29
flip214hmmm, " ..." doesn't find a python module - but "python cinder/tests/unit/..." does. Hrmpf.08:29
zigoThanks ! :)08:29
sheelzigo: refer
duleksheel: If you could propose a commit to include non-minified versions of these bootstrap files I'll approve it right away.08:30
zigoAh, super cool !08:30
sheeldulek: I have already08:30
sheeldulek: refer
duleksheel: Oh. Even better! Reviewing. :)08:31
sheeldulek: but this depends on which is waiting for final +A only08:31
zigoFYI, we're not even packaging os-api-ref in Debian, it's not needed.08:31
duleksheel, zigo: Okay, I'll review both now.08:32
sheeldulek: thank you..08:32
sheelzigo: thanks for raising this.. this will help my patches to merge soon...  :)08:32
zigoI'd very much appreciate a ping once all of this is merged, so I can upload Cinder Newton b1 (+ a few commits) to Debian experimental.08:32
zigoI'm putting this on hold in the mean while.08:32
zigosheel: Awesome! :)08:32
zigoI was about to report the bug to launchpad, I guess it's not needed.08:33
zigoShould I?08:33
sheelzigo: not required..08:33
zigo(I'm one click away, the form is already filled...)08:33

e0nedulek, zigo: what is the issue with mimified js files? they containt MIT licence headers09:32
zigoe0ne: This is an already built artifact, this is not source code.09:33
zigoe0ne: Therefore, it's non-free.09:33
e0nezigo: it makes sense09:33
zigoe0ne: All downstream distros will refuse the whole package because it will be considered non-free.09:33
e0nezigo: does any other openstack project have the same issue?09:36
zigoe0ne: Yeah, it's been years I'm constantly complaining about this kind of stuff... :)09:37
zigoThings get fixed on a case-by-case basis after I open bugs.09:37
zigoGenerally speaking, people understand, though find it very annoying (me included, it annoys me but I follow the Debian rules...).09:38
*** nikeshm has joined #openstack-cinder09:38

nikeshmdulex: i tried to run unit tests on other machines, which do not have access to backend09:50
nikeshmthey are passing09:50
flip214ah, "openstack server show" returns the data09:52
e0nedulek: so, everything we need is to merge that patch, right?09:52
*** sgotliv_ has joined #openstack-cinder09:55
duleke0ne: That's right, but without the 316587 it will fail and there are mistakes in 316587. So i think we should fix 317283 by doing minimal required changes in it and then merge it.09:56
*** takedakn has joined #openstack-cinder09:56
openstackgerritSheel Rana proposed openstack/cinder: Updated volume, version, limit, metadata API-ref
sheeldulek: mistakes are fixed ^^10:00
sheele0ne: we are updating that through 31728310:00
duleksheel: Sure, but I'm not sure if I'm comfortable enough to approve it without manually checking all the calls if they are compliant. I would prefer making 317283 independent of 316587 and including minimum required fixes in 316587.10:02
dulekThat way we would just approve 317283 and continue review on 316587.10:03
sheeldulek: Let me find if i have command output with me which have details of manual output10:03
sheeldulek: give me 5 min10:03
duleksheel: What's that?10:08
sheeldulek: api calls10:08
sheeldulek: using curl10:08
sheeldulek: this contains output as well as commands with body10:08
sheeldulek: so will be easy to confirm10:08
duleksheel: Suuure, but still to completely review 316587 it would take me hours. And I was able to find mistakes in it with just a superficial look, so I'm not comfortable with approving it without that diligent review.10:10
dulekAnd to help zigo we need 317283 as soon as possible.10:11
sheeldulek: thats ok, but believe me you found all what was missing... but yep its always good to fully sure...10:11
sheeldulek: ok, let me know what is expected from me now?10:11
*** itzdilip has quit IRC10:11
sheeldulek: happy to help10:11
dulekSo I would say the best course of action is to make these to independent by including minimal set of needed fixes in 317283 and then continuing to review 316587.10:11
dulek(if "the minimal set of needed fixes" isn't really huge)10:12
sheeldulek: let me give a look..10:12
sheeldulek: ok, i think its easy.. let me submit it in next half an hour10:14

scottdaI think so, yes. Although the docs had quite a few steps, but I think that's the gist of it.12:11

tbarrone0ne: i do see that the patches overlap.  I'm going to go on and refresh mine in case reviewers end up agreeing with Hope-Marly that we should just first make the change to get backwards compatibility, then separatedly add new properties (e.g. cluster name and connect_timeout).12:18

openstackgerritIvan Kolodyazhny proposed openstack/os-brick: Make RBDImageMetadata and RBDVolumeIOWrapper re-usable
tomoiagascottda: the yesterday issue, where deleting an instance did not release the volume happened because I used the cinder client attach and detach commands (I had my reasons). More info here, seems an old issue:
scottdatomoiaga: Ahhh..that would explain it.12:38
scottdatomoiaga: You can cleanup the cinder DB state with the 'cinder reset-state ....' command12:39
tomoiagascottda: back when I used the cinderclient, nova required me to give it a device, and I didn't want to do that so I used the cinder client :)12:39
openstackgerritTom Barron proposed openstack/os-brick: Fix ceph backup failure to do incremental backup
tomoiagascottda: indeed12:39

sheellocust: AFAIK, there should not be dependency for deleting snapshot after cloning volume from it..13:30
*** rlrossit has joined #openstack-cinder13:30
dulekscottda: But… Why not ceph?13:30
scottdadulek: Yes, that's a good idea...13:31
scottdadulek: I'm just a former NFS guy, but Ceph is probably a better choice.13:31
locustsheel  ---  it is because of usege zfs13:31
locustand its native cloning features13:31
dulekscottda: I mean NFS explodes harder when we're messing with it without synchronization, but it will be crazy-non-deterministic to fail.13:32
sheellocust: ohk... so thats driver specific behavior...13:32
sheellocust: I think lvm will allow to delete that..13:32
sheellocust: may be you can try this ...13:32
scottdadulek: Yeah, NFS syncing is unreliable. It's not the best choice, just the first thing that popped into my head.13:32

jsheerenbut! i can still attach it to instances and format it, create filesystems, etc16:26
jgriffithsmcginnis: true statement16:26
jsheerenhow can i fix this so i can still extend detached volumes16:26
openstackgerritSean McGinnis proposed openstack/cinder: Add test type clarification to devref
jsheerenhow can i fix the ownership?16:27
jsheerenanyone seen this before?16:27
jsheereni'm on the mitaka release btw16:27
smcginnisjsheeren: Sorry, haven't done much with NFS myself. There's usually a few folks around here that have some pretty good knowledge on permissions.16:27
jgriffithbswartz: weren't you working on the permissions swapping for NFS at one point?16:28
jgriffithbswartz: or maybe it was eharney ?16:28
jsheerensmcginnis: thanks, i was hopeing someone could point me in the right direction.   i'm thinking it's the nfs export settings, but not sure (and cannot play with the settings, our storage guy must do this)16:28
smcginnisjsheeren: Yeah, that's what stuff like that usually comes down to.16:29
smcginnisjgriffith: I'm hoping to play around with your attach workflow this afternoon. Just at a high level glance, I like the direction so far.16:29
jgriffithsmcginnis: cool... I'm working out the nova side of it right now, so maybe have something for you to test with other than manual calls later today16:30
smcginnisjgriffith: That would be huge, IMO. If we can show a working end to end solution that's going to be a lot easier.16:30
jgriffithsmcginnis: I'll hollar when I push that16:30
smcginnisjgriffith: Awesome16:30
jgriffithit'll be later today or tomorrow16:30
jgriffithmy goal is before the week-end if I can avoid interruptions/meetings :)16:31
smcginnis[jgriffith translator: it'll be tomorrow or some time next week]16:31
jgriffithsmcginnis: touchet16:31
jsheerensmcginnis: i'm looking at:  where you marked it as obsolete.  if i read point 1, a) "root squash is enabled on the NFS server"  i think this is what i'm missing16:31
smcginnisjsheeren: Hmm, that was a batch bug close for old bugs sitting out there. :/16:32
smcginnisjsheeren: But hopefully that has the clues you need.16:33
smcginnisjsheeren: But from my limited NFS experience, root squash has been a thing impacting others.16:34

*** sdake_ has quit IRC16:52
Anticimexjgriffith: it works in the liberty setup16:54
jgriffithAnticimex: interesting16:55
Anticimexbut if mod_wsgi is the supported way to go, i guess puppet-cinder can roll that out16:55
Anticimexthough others will run into this as well (as shown by above :) )16:55
jgriffithAnticimex: Yeah, my point was I tihnk it's a Cinder bug that needs addressed perhaps new in M16:56

jgriffithAnticimex: so that pushed the eventlet server up into the oslo code and removed the ssl portions17:00
jgriffithAnticimex: I think what we need to do is write an init for wsgi in Cinder that takes the option and passes it up17:00
jgriffithAnticimex: probably the right thing to do, just not quite *done*17:01

jgriffithfor now on M the workarounds appear to be your only option... unless somebody more familiar with the SSL stuff knows another solution that I don't see17:32
Anticimexthat's ok, i'm hopefully past halfway done with turning up the wsgi. we thus far already run keystone under wsgi and the puppet-openstack things are fairly similar, so i could copy/paste a bit17:34

Anticimexor hrmpf. puppet-cinder workaround foiled. stable/mitaka release of it doesn't do the wsgi at all, it's post stable/mitaka, where i ran into some puppet lib dependency fail. so i'm back to unbreaking that then i guess17:38

akerrtbarron: ya i'm not saying its necessarily a problem, just venting that i didn't see this earlier18:42
tbarronakerr: but are the locks supposed to coordinate between nova and cinder, or only on a single node?18:42
hemnait's only an issue if you have n-cpu and c-vol on the same host18:43
akerrtbarron: the brick locks are specifically synchronized to a single namespace so that nova and cinder can coordinate... and multinode locking has the whole dlm issue18:43
