jgriffithhemna patrickeast smcginnis can you guys do me a favor when you get a chance and let me know what it is that your FC drivers are returning on that terminate connection call?00:07
jgriffithhemna patrickeast smcginnis Swanson I started an etherpad here:  https://etherpad.net/p/cinder-fcResponses-terminate_connection00:07
smcginnisjgriffith: A bunch of crap.00:07
jgriffithif you guys want to just dump some info in there that would be helpful00:08
jgriffithsmcginnis LOL00:08
jgriffithsmcginnis perfect!00:08
smcginnisjgriffith: Swanson can probably give a more accurate answer though.00:08
smcginnisOr at least more specific.00:08
jgriffithThe key in that etherpad is also "what it's used for" :)00:08
hemnajgriffith, https://github.com/openstack/cinder/blob/master/cinder/volume/drivers/hpe/hpe_3par_fc.py#L378-L39300:08
jgriffithhemna and the "what it's used for" part?00:09
smcginnisIt _should_ all be pretty consistent between drivers. It needs to be the info the FC zoning needs.00:09
hemnathe important piece there is returning initiator_target_map00:09
*** yangyapeng has quit IRC00:09
hemnathat piece is returned if and only if there are no more volumes exported from the array to the host00:09
hemnathe FCZM then tests to see if that's in the return00:09
hemnaif it is, then it removes the zone00:09
hemnaelse the fczm does nothing00:10
smcginnis{'data': {'target_wwn': 'deadbeef', 'initiator_target_map': xxx}}00:10
jgriffithhemna if it's just used by the FZM then WTF do we have to care at the manager?00:10
jgriffithhemna or anywhere outside of that for that matter?00:11
hemnawe don't00:11
hemnathat's what I was trying to say in the meeting00:11
*** catintheroof has joined #openstack-cinder00:11
smcginnisWe could certainly take the code that's building the dict to return into a call explicitly from the driver.00:11
jgriffithhemna ahh00:11
jgriffithhemna so the only problem is that it's the "opposite" of the way my method works currently?00:12
hemnamaybe os-brick uses the data on disconnect_volume too00:12
smcginnishemna: Huh, I see we're returning Discard in there too. Is that right?00:12
jgriffithin other words, I currently interpret any not None as "outstanding shared-connections"00:12
hemnaah yah00:13
jgriffithwhich this would actually indicate, the opposite; the Zone is done, so the ZM may be able to clean up00:13
* patrickeast catches up00:13
hemnabrick uses target_wwn from the return00:13
patrickeastjgriffith: yea thats correct00:13
jgriffithhemna what does brick do with that?00:13
hemnait's used to discover which paths on the system to remove00:14
*** lixiaoy1 has joined #openstack-cinder00:14
patrickeasthemna: how would brick get the data currently though? we don't return it back up through the manager do we?00:14
jgriffithpatrickeast +100:14
* hemna looks00:14
jgriffithwe do not.. maybe the ZM stuff just doesn't even work anyway :)00:14
patrickeastnah, it works... but afaik it just removes the zoning00:15
patrickeastthen the initiator uses os-brick to get its own wwpn/wwns and calls os-brick00:15
patrickeasti think00:15
jgriffithhemna patrickeast so the idea was to try and make this work without having to go and modify all of the drivers, but it seems like maybe that's not going to work out00:15
hemnaso brick gets that from the bdm I think00:15
jgriffithso maybe what I'll need to do is create a special response and update *EVERYTHING* to use said response00:16
jgriffithhemna that would make sense, and be more in line with how the new code expects this to work00:16
hemnasorry guys, it's just been a while since I've messed with this00:16
jgriffithhemna that's ok, I don't mess with it at all :)00:16
patrickeastjgriffith: you do now :P00:17
jgriffithI just want to make sure that we have a defined interface and expected responses and actually stick with them00:17
jgriffithpatrickeast LOL!!  Damn it!00:17
*** jdurgin has quit IRC00:17
hemnayah, so nova passes that connection_info in to brick from the bdm00:17
patrickeasti'm game for defining a more standard response for the drivers to return from terminate_connection00:17
patrickeastor even a new driver api that just asks given some host info if its safe to disconnect or not00:18
smcginnisWhatever we end up with, let's make sure it's clearly spelled out here: https://github.com/openstack/cinder/blob/master/cinder/interface/volume_driver.py#L20300:18
jgriffithhemna so that's *good* news, because that's how I'm trying to move the new stuff to work, and in cases where that isn't there or doesn't work then use attachment-get00:18
jgriffithsmcginnis noted!00:18
hemnayah so I think the terminate_connection dict passed back is only used by the FCZM at this point00:18
smcginnispatrickeast: That could be racy to make it a separate call.00:18
smcginnispatrickeast: But that could be possible too.00:18
*** jerrygb has quit IRC00:18
hemnaand I think we wanted to nuke the decorator and just explicitly call the add/remove zone in the drivers00:18
patrickeastsmcginnis: meh, the whole thing is racy00:18
jgriffithhemna we should probably make that an inheritiance/wrapper of some sort00:19
*** david-lyle has joined #openstack-cinder00:19
smcginnispatrickeast: Hah, fair point.00:19
hemnajgriffith, heh, I've tried to enforce that a dozen times00:19
hemnavia the base FC volume driver00:19
jgriffithwe don't even have a dozen FC drivers do we :)00:19
hemnaABC crap has greatly complicated that00:19
jgriffithjust kidding00:19
hemnaso I gave up00:19
jgriffithyou can't hit me from here00:19
jgriffithhemna hmmm... ABC, shall I rant :)00:20
hemnakill the alphabet00:20
jgriffithhemna BUT... honestly here's the thing00:20
jgriffithif somebody doesn't inherit like you say it doesn't matter00:20
jgriffithand even that by itself doesn't solve the problem00:20
hemnaif everyone would have written an FC driver using the base FC class, then we could do all of this in the parent base class00:20
jgriffithWhat I'm getting at is just making sure the drivers all behave the same, if that means there needs to be some wrappers and indirection/helper methods that's cool00:21
hemnayah, so I will abdicate that fight at this point00:21
jgriffithhemna ahh, yeah; well that's always the case with stuff like this.  The theory is great, but reality.. not so much00:21
hemnayah I'm all for the same behavior, well at least with respect with what they are supposed to accept and return00:21
jgriffithOO programming in general.. it's. a farce :)00:21
jgriffithhemna the problem is that you may have different views on what those things are :)00:22
hemnafrankly the fczm usage has been an evolution from the beginning and hadn't needed to change it00:22
*** sdague has quit IRC00:22
smcginnisjgriffith: Well, OO programming in a loosely type language is kind of a farce. It can work very well in other languages. :)00:22
hemnabut I'd much rather make this easier to do00:22
jgriffiththe info on that etherpad will help, I'll try and confirm that the data isn't even actually going back to the caller or being used (or if folks with FC drivers want to check that would be cool)00:23
jgriffithsmcginnis hehe.. well that's a fair point00:23
jgriffithsmcginnis like Java where you have no choice?00:23
smcginnisYou must implement this... unless you don't want to, that's cool too.00:23
jgriffithsmcginnis yeah, that's what's F'd up00:23
hemnathen you stab yourself in the eye with classpath00:24
jgriffithand I'd like to have a long talk with the person(s) that started us on the "everything's a snow flake"00:24
jgriffithoh well, at least we can try and fix this up nicely00:24
smcginnisjgriffith: +100:25
smcginnispatrickeast: This seemed to regulary affect the Pure driver from showing up in the driver list: https://review.openstack.org/42099300:26
smcginnispatrickeast: So you might have some interest in that.00:26
*** mtan_____ has joined #openstack-cinder00:28
smcginnisjgriffith: That would be a good point for that.00:29
patrickeastsmcginnis: interesting, whats the list used for?00:29
smcginnisjgriffith: We get all of that connection info there anyway.00:29
*** mtanino has quit IRC00:29
patrickeasti recall various points in time we talked about using an automated list of drivers for things... but afaik most public ones are manually maintained00:29
smcginnispatrickeast: To get the list of all drivers. Most visibly it's used for the published driver list, but I still am hoping to expand that to do additional checks and things.00:30
smcginnispatrickeast: There's also a patch somewhere to replace our driver capability wiki table with an automatically generated table.00:30
jgriffithsmcginnis hmmm?00:30
hemnaI think it includes the new CI wiki name in the output too00:30
smcginnispatrickeast: http://docs.openstack.org/developer/cinder/drivers.html00:30
smcginnisjgriffith: Was referring to what you were typing in the etherpad.00:31
jgriffithsmcginnis yeah, which part?00:31
hemnayah, that's I think how those links to the CI are that list00:31
smcginnishemna: Yep. And Unsupported now too if applicable.00:31
hemnaooh unsupported too00:31
smcginnisjgriffith: connection_is_shared00:31
smcginnisjgriffith: We're querying that info anyway.00:31
jgriffithsmcginnis so I was getting at adding the connection_is_shared key, and if it's not there, or None we interpret it as false00:31
smcginnishemna: Public shaming. :D00:31
jgriffithsmcginnis oh?00:32
*** jdurgin has joined #openstack-cinder00:32
smcginnisjgriffith: That sounds good to me.00:32
hemnais 3PAR in that list yet?00:32
smcginnisjgriffith: If it's not there, then the driver isn't aware of multiattach.00:32
patrickeastsmcginnis: oh interesting, didn't even know that list was there, i always went off of https://www.openstack.org/marketplace/drivers/ https://wiki.openstack.org/wiki/CinderSupportMatrix or  http://docs.openstack.org/newton/config-reference/block-storage/volume-drivers.html00:32
* patrickeast wonders if there are too many different lists00:32
jgriffithsmcginnis right, but there are drivers like Pure that share connections still00:32
hemnaneed a list of lists00:32
smcginnispatrickeast: There are. This is one list to rule them all. ;)00:33
jgriffithbut I don't know how that works today anyway00:33
smcginnispatrickeast: Assuming it actually is able to get all the drivers right.00:33
patrickeastsmcginnis: haha yea, that would be ideal00:33
smcginnispatrickeast: If you notice, that also lists all fczm drivers and backup drivers.00:33

smcginnishemna: While we're on the subject: https://review.openstack.org/#/q/status:open+project:openstack/cinder+branch:master+topic:ci_unsupported00:35
smcginnispatrickeast, hemna: Double whammy.00:36
hemnasmcginnis, so......00:36
hemna3PAR CI hasn't been passing for quite a while.....00:36
hemnaa long while00:36
smcginnishemna: I'll run my report again. It's been a few weeks now and last time I ran it there were a few that were right on the edge.00:37

smcginnisI hope to have the CI report automatically published to here eventually: http://cinderstats-dellstorage.rhcloud.com/00:37
smcginnisFirst I should figure out why my review could job doesn't appear to be running.00:38
smcginnisCrap, and what happened to my other reports too.00:38
smcginnisHah, guess I've got some work to do there.00:38

hemnaunless I ran that incorrectly00:40
smcginnishemna: OK, I'll take a look tomorrow.00:42
hemnawhat do you use to check the CI status?00:43
patrickeastjgriffith: that proposed dict format on https://etherpad.net/p/cinder-fcResponses-terminate_connection looks good to me, seems like it would be simple enough for drivers to do that, and for the manager to make reasonable assumptions if it isn't there00:43

asettleHey - wondering if someone is able/around to help me triage a bug. We've been getting a lot of bugs for manuals content with configuration content that I don't know much about.14:07
openstackLaunchpad bug 1644562 in openstack-manuals "Install and configure a storage node in Installation Guide" [Undecided,New]14:07
asettleUsing the Ubuntu install guide, the reporter was unable to create a volume. cinder-volume does not start.14:07
asettleNewton install guide.14:07

smcginnisasettle: I just did an install from that guide not long ago. Some dependency must have changed.14:14
smcginnisasettle: Appears to be from this: Unrecoverable Error: Versioned Objects in DB are capped to unknown version 1.11.14:15
smcginnisdulek: You still around? ^^14:15
asettleA successful install from that guide?14:15
smcginnisasettle: The newton Ubuntu guide on docs.o.o, right?14:15
asettleThat's the one, yep smcginnis14:16
*** ociuhandu has joined #openstack-cinder14:16
smcginnisasettle: Yeah, maybe about a month ago now, but recent enough that I know it was at least working as described recently. :)14:17
asettleOh good :) (thank god)14:17
smcginnisasettle: ;)14:18
asettleOkay, then I have absolutely no idea how this reporter ended up at this point tbh :/14:18
smcginnisLooks like oslo.versionedobjects was probable updated since I did it. 1.19.0 went out Dec 1 and 1.20.0 went out Dec 6.14:18
asettleThe reporter needs to update?14:18
smcginnisMy suspicion is either that or some other library has made a change that broke something.14:18
smcginnisasettle: Or we are not capping something that we need to.14:19
smcginnisasettle: Either that or they missed something in the setup, but my first assumption is that we broke something, not them.14:19
asettleThat's a nice assumption :P i'm a lot more ruthless than that.14:19
asettleHm, okay, so - anyway to quickly verify this? Sorry for leaning on you a lot here, I've decided to bug triage my little heart out but it gets harder the more configuration info you need to know across *all* projects.14:20
smcginnisasettle: I can only imagine!14:20
asettleHahahha *sigh* *head desk*14:21
smcginnisasettle: Well, I have a basic understanding of the versioned objects stuff, but dulek is our resident expert on all of that.14:21
smcginnisasettle: He's usually around, so he'll probably be back soon. I'm sure it will be obvious to him. ;)14:21
asettleIt's always obvious to someone :P14:21
asettleThe bug and I can wait :) thanks for having a look though smcginnis !14:22
smcginnisasettle: That's the truth.14:22
asettledulek: shoot me a ping when you're in please :)14:22
smcginnisasettle: No problem. I'll keep it open in a tab so I remember to follow up if we don't hear anything.14:22
*** tlian has joined #openstack-cinder14:23
asettle:) wonderful, thanks! Me too - I'll stare at it and hope that via osmosis cinder configuration contextual information will just absorb.14:23
asettleSomething tells me that won't work, but hey, here's trying.14:23
smcginnisasettle: Hah, good luck with that. :P14:23

dulekasettle: If that's not clear enough I'll be happy to update it with your feedback.14:28
asettleAnd like magic dulek knows the things. dulek - could you explain to me what exactly you're pointing to? I know as much about cinder as I do about... Icelandic politics.14:29
*** pbandark has quit IRC14:29
dulekasettle: Basically this error happens if there are old, dead records in services, that reported older versions of either RPC APIs or objects.14:29
dulekasettle: Or - the code isn't checked out from exactly the same git ref and versions differ.14:30
asettledulek: oh! Thank you!14:31
asettleThat makes sense :)14:31
dulekasettle: There's one more mention in the 5th point here: http://docs.openstack.org/developer/cinder/upgrade.html#plan-your-upgrade14:31

dulekasettle: Awesome. I'll think about providing better feedback for the admin when this occurs.14:36

*** psachin has quit IRC14:37
duleksmcginnis: Or they've reused old database.14:37
smcginnisdulek: Yeah... whatever is going on, it doesn't appear to be a straight install through the install guide.14:38
asettle*Everyone* reports they are doing a straight install from the guide.14:38
asettleSome are easier to identify than others.14:38
smcginnisasettle: "Honestly, I didn't touch anything" (whole config is changed) :)14:39
asettleUgh. Yes. I had one bug report that was basically like "I've done *everything* you said in the guide, but here's my optional configurations, WHY DONT YOU DOCUMENT THIS"14:39
asettleIt was a very angry bug report.14:39

smcginnisasettle: For our storage product it was a joke for a while. *Every* bug was filed against our UI team, because obviously it was a UI problem that an error was displayed.14:41
asettleOh dear.14:42
asettleI'm trying to think of ways to reduce some of this bug count and make it easier for everyone to triage. So far I've come up with 'kill it with fire'.14:42
smcginnisasettle: Well, any other Cinder issues come up, feel free to point them our way.14:43
smcginnisasettle: Hah!14:43
asettlesmcginnis: will you regret that promise when I suddenly start spending an inordinate amount of time here? :p14:43

ildikovI added volumev3 to the context file in Nova as it's in your patch and I don't need the other hacks now15:47
ildikovI hardcoded the microversion now for local testing15:47
ildikovmriedem added a short note to one of the patches about negotiating about the microversion rather than make it a config option15:48
scottdayeah, I saw that. I can add a placeholder microversion in that patch until we land the cinder stuff and know exactly what that will be...15:50

scottdaI think if we don't have a single focus, we'll end up with the usual list of everything wrong we'd like to fix.16:08
scottdahemna: Hi.16:08
scottdaAnyone have anything about tests they'd like to talk about?16:09
erlonscottda: whast do you mean by single focus?16:09
scottdaerlon: Well, if we come up with the 10 areas we need to write tempest/functional tests for, none of them will get done....16:10
scottdaerlon: If we pick one, there is hope that we can focus and perhaps make progress.16:10
scottdaThen, we could add more if there is time.16:10
geguileoerlon: I have a fix for the manage issue16:10
scottdasmcginnis: had suggested this, and I agree.16:10
geguileoerlon: I'm going to look into the retype with migration now16:10
erlonscottda: hmm, I see16:11
scottdaBut, of course, people can work on whatever they want (or whatever their employer lets them do)16:11
openstackgerritMerged openstack/os-brick: Fix a wrong indentation  https://review.openstack.org/42113716:11
erlongeguileo: I remember I have some patches but didnt submit16:11
erlongeguileo: ill put a patch and you can give a look if theres something missing16:11
scottdageguileo: I had left some work undone on retype with migration...we hope we can end up calling Nova swap volume, to test that as well.16:11
geguileoerlon: lol, then our patches will be fighting one another16:11
erlongeguileo: haha16:12
scottdageguileo: erlon I think that using LVM will cause a Nova swap_volume if the hostname for both backends is different. Otherwise, it won't call swap_volume.16:12
geguileoscottda: I have just fixed the manage one, I have to look at the other case, as it may be related16:13
*** bswartz has quit IRC16:13
erlonscottda: I dont reacall now, but I believe swap_volume is always being called for the attached migration16:14
scottdaOK, cool. I think there is a local nova test for swap_volume, but nothing that exercises it from Cinder...16:14
scottdaand therefore not testing of anything that has Cinder call Nova, and using the novaclient, etc.16:15
markus_zscottda: Would you maybe have a look at https://review.openstack.org/#/c/413684/ ? Needs a 2nd +2.16:15
scottdaerlon: No, I don't think it will with a single-node LVM setup, since the hostname is the smae for both backends.16:15
scottdaerlon: I thought I had a patch that worked, but there is some logic to optimize things for the case of 2 backends on the same host...I'll try to find it...16:16
scottdamarkus_z: I'll put it in my queue to have a look16:16

scottdaerlon: That is it, I think16:19
*** diablo_rojo has joined #openstack-cinder16:19
erlonscottda: yep, theres this case, I found it because I was testing migration between pools in the same backend16:21
scottdaerlon: So, does your test patch get around this? If not, we'll go with geguileo16:21
erlonscottda: which is the must be the same behavior you mentioned in LVM16:21
erlonscottda: yes16:21
erlonscottda: ow wait16:22
scottdaerlon: I think we really need to check the Nova logs to verify. Otherwise, we'll need an additional test. And this already takes a bit of time to run.16:22

openstackgerritint32bit proposed openstack/python-cinderclient: Add snapshot-id filter to get volumes via cli  https://review.openstack.org/41651016:27
geguileoerlon: why do we need to say that None is not equal to None for host equivalency?16:27
erlongeguileo: I don't think we need to. Actually they should not be considered equal16:29
erlongeguileo: if clustering is not configured, both are None, but the hosts are actually different16:30
geguileoerlon: Why should they not be considered equal?16:30
geguileoerlon: but that should be ok16:31
geguileoerlon: clusters are equal but not the hosts16:31
erlonthe false positive happens here:https://github.com/openstack/cinder/blob/master/cinder/volume/manager.py#L229516:31
*** bswartz has joined #openstack-cinder16:31
erlongeguileo: yeah but if does not have cluster_name set, it will lead to a false positive as will compair None == None16:33

openstackgerritint32bit proposed openstack/python-cinderclient: Add snapshot-id filter to get volumes via cli  https://review.openstack.org/41651016:43
erlonscottda: another point I was wondering weather we should pick some of that and move to our intree tests16:44
scottdaerlon: That could be a good idea (moving in-tree), as that may be why some languished in the review queue.16:45
erlonscottda: mhm, the bad side is that we loose the eyes of tempest core, but that's is hard to get anyways16:46
scottdaYes, the "hard to get" part is what I'm talking about16:47
smcginniserlon: I'm sure if we merge something especially bad, we'll get their attention. ;)16:47
erlonscottda: yeap16:47
smcginnisscottda: Right, it's lack of attention I think that has prevented us from adding some of these tests.16:47
erlonsmcginnis: haha, yeah16:47
scottdaOr it they merge something especially bad...16:47
smcginnisscottda: ;)16:48
scottdaOK, well thanks erlon . Keep us informed as to what you identify (if still in Tempest).16:48
scottdaI reckon we'll pay attention no matter what if you move them to cinder in-tree16:48
scottdaOK, anything else?16:49
xyangso regarding tempest tests for groups, should I submit them in-tree or in tempest?16:50
*** salv-orlando has joined #openstack-cinder16:51
scottdaxyang: Good question.16:51
smcginnisxyang: Hmm, maybe try in tempest, and if there is resistance there move to in-tree?16:51
erlonscottda: sure, welcome16:51
smcginnisWe've talked about using our in-tree as kind of an incubator for tempest tests, but I think that one might be good to just go there.16:52

* patrickeast is confused21:32
patrickeastanyone know how our objects are lazy loading things that might be null?21:33
patrickeastlooking at this method https://github.com/openstack/cinder/blob/master/cinder/objects/snapshot.py#L21921:33
smcginnispatrickeast: It's blowing up there?21:34
patrickeastif i try and look at the snapshot["group_snapshot"]21:34
patrickeastthe db call to look it up by id is coming back with an exception, because it isn't in a group21:34
patrickeastwhich seems right21:34
patrickeastbut the object call then raises the exception instead of just returning null21:34
patrickeastor None, or whatever21:34
patrickeastwe even specify it can be None https://github.com/openstack/cinder/blob/master/cinder/objects/snapshot.py#L7021:35
smcginnisHmm, not sure on that.21:35
*** xyang has quit IRC21:36
patrickeastoh hmm it blows up for "cgsnapshot" too21:37
patrickeasti wonder if its supposed to actually support this or not21:37
*** xyang has joined #openstack-cinder21:37
smcginnisI think that nullable=True has more to do with the database than the objects.21:38
*** xyang has quit IRC21:38
*** xyang has joined #openstack-cinder21:39
smcginnisBut it does seem if it's nullable, we should just be able to get back null and not blow up.21:39
patrickeastit kinda looks like those calls should be wrapped with try/catch blocks and just set the value to None21:39
smcginnispatrickeast: You may be right.21:39
patrickeastmaybe i'll put a patch together and let dulek and geguileo look at it when they are up and around21:39
patrickeastfix it for now and figure out if its the "right" way later21:40
*** xyang has quit IRC21:40
*** crose has quit IRC21:41
smcginnispatrickeast: That sounds like a decent plan. It would be good to get their take on it.21:41
patrickeastsmcginnis: oo yea, we do the same kind of thing on the volume object with the glance meta data21:45
patrickeasteasy fix then21:46
smcginnispatrickeast: So we have to do that for each object?21:49
*** timcl has quit IRC21:49
*** e0ne has quit IRC21:49
patrickeastsmcginnis: yea, but i think its the minority of attributes we have to deal with like this21:49
patrickeastsmcginnis: just the ones that are links to other objects and are OK to be null21:49
smcginnispatrickeast: Hmm, I guess. Just another little detail to have to be aware of and look out for though.21:50

*** knomura has joined #openstack-cinder23:18
_alastor_patrickeast: seems weird that the glance api version would be set by cinder....23:18
patrickeast_alastor_: i guess it depends on what you want, if you want cinder to use the v2 api when i calls glance thats the one since its configuring the glance client code in c-* services, if you want glance itself to run exposing a different version then i think it would require changes to glance configs23:20
