*** david-lyle is now known as david-lyle_afk00:37
nikesh_vedamsjgriffith:thanks but is this is going to merge00:40
nikesh_vedamsjgriffith: because we have to do small changes according to this if it is going to merge00:41
*** jungleboyj has joined #openstack-cinder00:42
nikesh_vedamsjgriffith: because this code have some pure virtual functions which every target has to override00:43
openstackgerritDanny Wilson proposed openstack/cinder: Enabling volume replication on PureISCSIDriver
jgriffithnikesh_vedams: yes, I told you that Monday00:58
*** fischerw has quit IRC00:59
nikesh_vedamsjgriffith:so without merging of that code we cannot use right01:03
nikesh_vedamsthats why we didnot change01:03
openstackgerritWalter A. Boring IV (hemna) proposed openstack/cinder: WIP: Remove Brick from cinder codebase

openstackgerritAnthony Lee proposed openstack/cinder: Adding manage/unmanage support for LeftHand driver
openstackgerritAnthony Lee proposed openstack/cinder: Adding manage/unmanage support for LeftHand driver
nikesh_vedamsjgriffith: hmm01:24
nikesh_vedamsjgriffith:so if patch is merged after our patch than in that case we have to file bug i guess.01:27
jgriffithnikesh_vedams: just fix your code and submit a patch01:28
jgriffithnikesh_vedams: it's not that hard01:28
jgriffithor a big deal01:28
jgriffithI suggested the other day you either:01:28
jgriffith1. add the other patch as a dependency and fix yours up01:28
jgriffith2. just submit yours knowing that your going to have to come back and fix it01:28
nikesh_vedamsso can i submit it today night01:28
jgriffithnikesh_vedams: this seems difficult for you, so if you'd like I"ll just revert my +2/A on your patch and you can wait01:29
jgriffithnikesh_vedams: sure, but you sort of need 148038 to merge before you submit01:30
jgriffithnikesh_vedams: but yes, you certainly can ... or just wait for everything to land then fix your code up tomorrow01:30
jgriffithnikesh_vedams: one of those patches is likely to cause unit test failures and need reworked anyway... we'll see01:30
jgriffithnikesh_vedams: do you understand what I'm getting at here?01:32
jgriffithnikesh_vedams: there will be a race in the gate, one will break the other01:33
jgriffithnikesh_vedams: I was trying to be nice and just approve yours01:33
*** davechen has joined #openstack-cinder01:33

nikesh_vedamsjgriffith:sorry john for this mess01:37
*** tsekiyam_ has quit IRC01:38
jgriffithnikesh_vedams: nahh... it's not a mess at all01:38
jgriffithnikesh_vedams: that's kinda my point, it's not a big deal01:38
jgriffithnikesh_vedams: either your patch fails gate, or mtanino's will (or both)01:39
jgriffithor they don't (which means the unit tests need work) :)01:39
jgriffithand we fix it and submit it01:39
jgriffithnikesh_vedams: the key is this way it's a quick turn around, because it's just fixing the issue and readding the +2/A01:39
jgriffithnot a big deal01:39
jgriffithnikesh_vedams: you worry too much! :)01:39
anishjgriffith: aww sweet, mtanino's patch finally landed01:43
anisherr, -ish01:43
jgriffithnikesh_vedams: you got lucky01:43
anishmakes scst unhappy I see01:43
jgriffithyour patch won01:43
jgriffithanish: well... yeah about that :(01:43
anishit's gonna be stuck on gate eh01:43
jgriffithanish: we need to refactor it to fix the code Nikesh just landed01:43
jgriffithanish: yep, it was going to be mtanino's or nikesh_vedams 's01:44
jgriffithit's mtaninos01:44
anishless pain for me, not mine01:44
* anish gets busy rebasing01:44
jgriffithanish: ahh... I was just getting ready to pull it01:44
jgriffithanish: you mean rebase "your" patch?01:45
jgriffithanish: you'll be ok01:45
anishyeah, never made it in01:45
jgriffithanish: it's the scst code that merged01:45
anishyeah, I figured01:45
jgriffithanish: so mtanino's patch won't have the updates needed for scst to work01:45
jgriffithI'll see if I can get around to just fixing that01:45
anishI can take a look at that if no one else is, I'll be rebasing mine anwyays01:45
jgriffithbut then I'll get it merged and you should be fine01:45
jgriffithanish: sure01:46
jgriffithwe can both look :)01:46
anishsounds good. I feel like you're going to be faster than me :)01:46
jgriffithI don't know about that01:46

jgriffithnikesh_vedams: about have this done....02:04
jgriffithnikesh_vedams: quick question... might make it faster02:04
jgriffithnikesh_vedams: I need to create "_get_target_chap_auth"02:04
jgriffithnikesh_vedams: looks like you just use config file settings only for this?02:04
*** nellysmitt has joined #openstack-cinder02:04
*** thingee has quit IRC02:08
*** nellysmitt has quit IRC02:09
nikesh_vedamsso we are checking that self.chap_username and self.chap_password in cinder.conf02:11
jgriffithnikesh_vedams: yeah, or random generate02:11
jgriffithnikesh_vedams: but I just noticed something....02:11
jgriffithnikesh_vedams: well... first you only do that on create, so it's not persisted anywhere (if it's not in config)02:12
jgriffithnikesh_vedams: that's not going to work very well if you restart the service and try reexport02:12
jgriffithnikesh_vedams: the other thing.....02:12
jgriffithnikesh_vedams: create_iscsi_target takes an optional "chap_auth"02:13
jgriffithnikesh_vedams: but it's not used anywhere02:13
jgriffithnikesh_vedams: so I'm kinda confused how you're doing chap?02:13
jgriffithnikesh_vedams: well.. I mean...02:13
jgriffithnikesh_vedams: ok, so you're just handling the chap pieces on create-export02:13
jgriffithguess that's ok02:13
jgriffithbut still have this pesky persist problem02:14

*** Mandell has quit IRC02:23
sreedhar_vedamsRegarding the CHAP settings for SCST targets, we are using config file for targets to define their own chap strings if they don't support dynamic chap strings. If user does not define the chap strings in cinder.conf file, then we use the vutils to create the strings.02:23
openstackgerritJohn Griffith proposed openstack/cinder: Refactoring for export functions in Target object
jgriffithnikesh_vedams: sreedhar_vedams ^^02:26

jordanPmuraiki, you are correct16:26
jordanPcinder sends "notifications" on a messages bus (ie rabbitmq)16:26
muraikiI saw that in older versions of cinder there was an audit script that generated these notifications, but that script doesn't exist in icehouse. I've tried searching through the cinder repo, but haven't been able to figure out how the notifications are now generated16:27
muraikiwould you be able to point me in the right direction?16:27
muraikioh, actually it looks like I have it backwards... the audit script is in master, but not icehouse or juno16:29
muraikiultimately, my problem is that I'm stuck on icehouse and wanted to see if I could tie into those snapshot notifications somehow16:30
muraikibut perhaps that isn't possible in icehouse :(16:30

kallebeHello. I have a question, but first I want to say that I am very new to Gerrit: why does gerrit sometimes create a new change request instead of just commiting a new patch set?18:31

zzzeekhi folks, can someone give me some insight on and under what circumstances this occurs, how frequently, when it started, etc. ?20:26
openstackLaunchpad bug 1417018 in Cinder "Cinder encounters dbapi error: NoSuchColumnError: "Could not locate column in row for column '%(140070887032400 anon)s.volumes_id'"" [Undecided,New]20:26
eharneyzzzeek: that specific report happened on EMC's CI platform...   xyang: happen to know anything about that?20:28
zzzeekeharney: that kind of issue is often something in SQLA internals, but they are typically very difficult to trip over, especially with the simple models openstack uses, id imagine this is related to the pagination code but there’s  a lot there and seeing the SQL would help20:29
eharneyzzzeek: it does look like it happened at initial cinder-volume startup, and likely when the volumes table is empty, if that helps any20:31
zzzeekeharney: so you’re saying, it was with an entirely deterministic startup sequence, yet it only happened once20:31
eharneyzzzeek: well... i've heard of two specific occurrences (not mine, unfortunately)20:32
eharneyzzzeek: i ended up looking at this bug because jbernard ran into it somehow20:32
jbernardeharney, zzzeek: ive been seeing this most of the day20:33
zzzeekit is also possible that MySQL itself is screwing up and confusing the result processing code.  if this issue happens very randomly when the program is being run in an otherwise entirely predictable and often-repeated way, that’s a possibility20:33
zzzeekjbernard: OK when did it start20:33
zzzeekjbernard: and is it local to some environemnts ?20:33
jbernardzzzeek: since this morning20:34
zzzeekjbernard: if i just load up a devstack and run that command will i get the error ?20:34
jbernardzzzeek: i cant speak for other env's ive only had access to my local one today20:34

eharneyi wonder if update_volume_stats is racing against set_voldb_empty_at_startup_indicator's (volume_get_all), may explain why it's not everywhere.  both of those happen right at c-vol startup20:35
jbernardive been working around it (drinking heavily) to rework my migration code20:35
*** patrickeast has joined #openstack-cinder20:36
zzzeekjbernard: any chance you can get it to log the SQL for me ?20:36
jbernardzzzeek: i can enable anything you need20:37
jbernardzzzeek: what specifically will help?20:37
zzzeekjbernard: ideally this would be an “echo=‘debug’” kind of thing.  i wonder if even the MySQL connection is being used in multiple threads20:37
*** bnemec is now known as beekneemech20:37
zzzeekjbernard: uh well SQLAclhemy has a log level “DEBUG” for the “sqlalchemy.engine” logger, can you turn that on ?20:37
jbernardzzzeek: sure, brb20:37
zzzeeklet me see if i can run a cinder locally here, my acutally-running-openstack-apps fu is very low20:38
jbernardzzzeek: if you can get devstack to work, that *should* be sufficient20:38
* eharney tries to think through whether the two places he noted above would be in the same thread... maybe, i think?20:38
zzzeekeharney: does cinder use threads?20:38
eharneyzzzeek: well, eventlet greenthreads20:39
zzzeekeharney: ah.  not likely then20:39
zzzeekeharney: because you aren’t using the MySQLdb patching feature, i hope20:39

jbernardzzzeek: where is the sqlalchemy.engine config?20:42

zzzeekjbernard:  openstack has a DB conf that id imagine is in cinder.conf, but in this case, this is just logging config that can be set anywhere python logging is being configured20:43

muraikihi all. I'm trying to set up the cinder-volume-usage-audit script in icehouse in my crontab. the comments in the script say I should be able to select a time period such as hour or month, but it doesn't seem to actually accept those as a command line argument. I can specify datetimes for the start and end, but it'd be nice if I could just use "hour" and have it cron hourly20:59

jbernardeharney: right21:12
jbernardeharney: it works21:12
jbernardeharney: but now it's not failing21:12
jbernardeharney, zzzeek: ill keep trying with debug enabled21:13
eharneyjbernard: maybe turn that off and turn on mysql server-side statement logging?  would maybe keep it more likely to fail if it is a race21:13
eharneyjust guessing21:13
zzzeekjbernard: are you getting SQL statements in the log ?21:13
jbernardzzzeek: yes21:13
zzzeekjbernard /  eharney : the second error makes it look a lot like either MySQLdb is screwing up or the connection is being mis-used in a concurrent way21:14

openstackgerritxing-yang proposed openstack/cinder: Kilo Consistency Group API update
hemna_the entire point of our original spec was to make creating volume types self contained and easy for admins, specifically for horizon users.23:34
*** mriedem has quit IRC23:34
hemna_which includes name, description, types for each key23:34
hemna_so that when someone is going through the new horizon wizard it's all there for what's running in cinder.23:34
*** mriedem has joined #openstack-cinder23:35
thingeehemna_: if I'm understand jgriffith correctly, we can still do that, but it would be up to the cinder-api to take this information and parse it and make it "pretty" or in json schema for horizon to consume23:35
hemna_so where does description for vendor keys come from then?23:36
hemna_john's gist has vendor keys, but no desc for them.23:36
hemna_at no point were we thinking of modifying how the scheduler worked or looked at capabilities reported.23:36
hemna_we simply wanted a way to give information to horizon users to create volume types.23:37
hemna_john's gist is nice though23:38
thingeeideally it would come from the driver. I can't speak for jgriffith though23:38
hemna_it's just lacking desc.23:38
hemna_thingee, that's what he had planned in our original spec23:38
thingeehemna_: I get that.23:38
hemna_the schema for the supported extra specs came directly from the driver itself.23:38
thingeehemna_: If I had to guess jgriffith doesn't really care about that part, so it was just neglected23:39
*** mriedem has quit IRC23:39
hemna_that's the only part we wanted.23:39

jgriffiththingee: the DS I propose does that23:53
jgriffithbut I guess it's not what they want, so ok23:53
jgriffithI'll leave it up to the rest of you23:53
thingeeI guess I envisioned the driver asking the backend itself. I think that's a wonderful thing for the driver to ask the backend, what are you capable of doing, set a standard way to parse it and pass it back up.23:53
jgriffiththingee: that's exactly what i just posted FWIW23:54
*** markvoelker has quit IRC23:54

jgriffiththingee: where the data structure is built and returned23:54
*** markvoelker has joined #openstack-cinder23:55
jgriffithseems to be a lot of confusion on this whole thing23:55
thingeeyeah but mine had descriptions and all that. It was a way for the administrator to deploy a backend, have cinder setup to talk to it, then ask for the current capabilities. Create extra specs based on that information. Horizon could take advantage of it so it doesn't have to be done in the cli or rest calls.23:55
jgriffithseems pretty simple and straight forward to me23:55
jgriffiththingee: rigth, but that's what makes things an absolute mess IMO23:55
jgriffiththingee: it's not Cinder's job to document vendor features in it's code IMO23:55
jgriffiththingee: I'm fine with "helping" admins with Cinder options and making sure they know what's available23:56
thingeecinder is not documenting it though. Cinder gets a request via cinder-api to ask the backend. Cinder just gets back the description and all that data from the backend. It's not hardcoded in the driver.23:56
thingeeit's just a pass through23:56
jgriffithbut I'm not using Cinder as an HP "command help"  vehicle23:56
jgriffithor a a documentation over RPC method23:56
jgriffiththingee: really?  This is just weird to me23:57
jgriffiththingee: I'm really surprised there's even any push back here to be honest23:57
thingeeMaybe users are crazy then. When I talk to people, they don't want to go through the vendor's cli or dashboard. They want to just talk to cinder or go through horizon.23:57
jgriffiththingee: hemna so for example, why don't you go propose a patch to Nova that exposes ALL KVM options and their description23:58
jgriffithsee how that goes over23:58
jgriffiththingee: wait... you're not talking about the same thing are you?23:58
*** hodos|2 has joined #openstack-cinder23:58
