| zioproto_switch | hello. I have a problem where cinder snapshot-list does not return all the snapshots. How ever snapshots are in the database, and they appear if called with cinder snapshot-show. I am running Kilo. I tried both cinder client and openstack client. am I hitting a known bug ? | 09:09 |
| zioproto_switch | I did not mention I am running cinder with ceph rbd backend, so the snapshots are ceph snapshots. Also, the snapshots are correctly created in ceph. The bug is that the snapshot-list is incomplete | 09:10 |

| *** links has joined #openstack-cinder | 09:18 | |
| dulek | zioproto_switch: Are these snapshot deleted/unmanaged? Check out `deleted` column in the DB. | 09:22 |
| dulek | zioproto_switch: Also these can be owned by another tenant. Admin can see snapshots from all the tenants using --all-tenants option. | 09:23 |
| zioproto_switch | dulek: no they are fine | 09:23 |
| zioproto_switch | dulek: no same tenant | 09:23 |
| zioproto_switch | I found the bug | 09:23 |
| zioproto_switch | because I have a script | 09:23 |
| zioproto_switch | that makes snapshot create | 09:23 |
| zioproto_switch | and then | 09:23 |
| zioproto_switch | to check that the snapshot is there, it will call later snapshot-list to check if the snapshot is the creating state | 09:23 |
| *** gcb has joined #openstack-cinder | 09:24 | |
| zioproto_switch | so it turned out that sometimes I create a snapshot. The snapshot is created successfully and I also get the ID from the output of snapshot-create, However the next snapshot-list calls will not list the snapshot | 09:24 |
| zioproto_switch | please check here. I wrote all the details of the troubleshooting http://lists.openstack.org/pipermail/openstack-operators/2016-March/009929.html | 09:25 |
| zioproto_switch | all the entries in the 'snapshots' table in the cinder DB look valid. However not all are listed in the snapshot-list output | 09:27 |
| openstackgerrit | Vipin Balachandran proposed openstack/cinder: VMware: Support for non-default port https://review.openstack.org/267450 | 09:27 |
| zioproto_switch | dulek: is there any other database table that is updated when creating a snapshot ? | 09:28 |
| dulek | zioproto_switch: Can you dump a few records that are shown and few that are not from the DB? | 09:28 |
| zioproto_switch | yes sure give me a minute | 09:28 |
| dulek | zioproto_switch: Also you can check out --debug option for cinderclient to take a look on the raw REST API output. | 09:29 |
| zioproto_switch | dulek: you want a select * from snapshots where id='id'; right ? for two snapshots, one that appears and one that does not appear, right ? | 09:31 |
| dulek | zioproto_switch: That would be cool. :) | 09:31 |
| zioproto_switch | I checked with --debug and the JSON object returned looks OK. The snapshots aremissing also there | 09:31 |

| *** Dongsheng has quit IRC | 09:45 | |
| zioproto_switch | dulek: I am back | 09:46 |
| dulek | zioproto_switch: I've looked through the code and I can't find any place where snap can be dropped. DB query looks fine as well. | 09:46 |
| dulek | zioproto_switch: Your grep is faulty maybe? :D | 09:46 |
| zioproto_switch | dulek: I tried to less and to find the id in the big list | 09:47 |
| zioproto_switch | dulek: anyway the list is like 5 times smaller than the entries in the database | 09:47 |
| *** anshul has quit IRC | 09:47 | |
| dulek | zioproto_switch: I guess you should place a breakpoint using pdb/ipdb in cinder/volume/api.py (get_all_snapshots) and see what's returned from the DB. | 09:47 |
| dulek | zioproto_switch: I don't really have an idea what's happening here… | 09:47 |
| zioproto_switch | did you read my email on the openstack-operators mailing list ? | 09:48 |
| dulek | zioproto_switch: Yup. | 09:49 |
| zioproto_switch | the problem is that this is a production system, with 2TB cinder volumes. When I try to reproduce the bug in a small scale in staging system I cannot repoduce it | 09:49 |
| *** qeelee has quit IRC | 09:49 | |
| zioproto_switch | it sounds like a race condition when creating the 2TB snapshots. I am not sure if i can insert the breakpoint the production system | 09:49 |
| dulek | zioproto_switch: Ah… No, breakpoint in production sounds like a very bad idea. | 09:50 |
| zioproto_switch | dulek: do you want I paste the output with --debug ? | 09:50 |
| dulek | I don't think this will change anything. | 09:50 |
| dulek | Thing is that snapshot-list call is really simple - it just gets stuff from DB and prints it. | 09:51 |
| dulek | And your DB entries look perfectly sane. | 09:51 |
| dulek | Are you using V1 API maybe? | 09:51 |
| zioproto_switch | so I am using CinderV2, how to double check this ? | 09:52 |
| sheel | dulek: could it be problem at cinder client end? | 09:52 |
| sheel | dulek: may be we can check cURL output once to check | 09:52 |
| zioproto_switch | I tried different version of cinder client and also openstack client | 09:52 |
| dulek | --debug should give you URLs it's calling. | 09:52 |
| zioproto_switch | ok give me a moment to make the pastebin | 09:52 |
| dulek | sheel: Well, zioproto_switch says that raw REST outputs from --debug are still missing the snapshots. | 09:52 |
| sheel | dulek: hmm | 09:53 |
| dulek | zioproto_switch: Yeah, maybe this --debug will be useful, let's look at the URLs generated. | 09:53 |

| dulek | e0ne: You're not alone in that opinion. :D | 13:11 |
| e0ne | :) | 13:11 |
| geguileo | +1 | 13:11 |
| *** jwcroppe has quit IRC | 13:12 | |
| e0ne | geguileo: why only +1? | 13:13 |
| geguileo | Because I have mixed feelings, as it probably breaks like 10 of my patches that are up for review and another 5 I have downstream for the Active/Active cleanup | 13:14 |
| geguileo | rofl | 13:14 |
| geguileo | Just kidding, +1 is because I meant as in "I agree with that statement" | 13:15 |
| geguileo | Not as in a review vote ;-) | 13:15 |
| e0ne | :) | 13:15 |
| e0ne | btw, it took about hour to rabase it :( | 13:15 |
| e0ne | mostly because of new imports | 13:15 |
| dulek | So it looks like besides having too much code we also have too much patches. ;) | 13:16 |

| e0ne | jgriffith: morning, John :) | 13:22 |
| jgriffith | Anybody try setting a volume to an Error status and then deleting it lately? | 13:22 |
| jgriffith | Looks like we never send the call down to the driver any more if the volume is in Error status | 13:23 |
| * dulek spins up a VM… | 13:23 | |
| e0ne | jgriffith: didn't try to do such things | 13:23 |
| jgriffith | dulek: hehe... I was just doing the same thing; incase I've got a mess in my current branch | 13:23 |
| *** arecknag has joined #openstack-cinder | 13:24 | |
| dulek | jgriffith: Current master: http://paste.openstack.org/show/491578/ | 13:25 |
| dulek | Seems to work okay. | 13:26 |
| jgriffith | dulek: hmm... odd | 13:26 |
| jgriffith | dulek: https://github.com/openstack/cinder/blob/master/cinder/volume/api.py#L369 | 13:27 |
| dulek | jgriffith: https://github.com/openstack/cinder/blob/master/cinder/volume/api.py#L359 | 13:27 |
| dulek | jgriffith: If it has no host set, then we don't know where to send the request. | 13:28 |
| jgriffith | dulek: Ohh.... you misunderstand me | 13:28 |
| *** arecknag has quit IRC | 13:28 | |
| dulek | jgriffith: So we're just deleting that from the DB. | 13:28 |
| jgriffith | dulek: we DO delete the object and db entry | 13:28 |
| jgriffith | BUT we never send the call to the driver which is really bad | 13:28 |
| *** qeelee has quit IRC | 13:28 | |
| jgriffith | dulek: so we get orphaned volumes on the backend | 13:28 |
| dulek | jgriffith: In that case we don't know where to send it. | 13:28 |
| jgriffith | dulek: well, that's a bug | 13:28 |
| jgriffith | we should never have that problem | 13:28 |
| dulek | jgriffith: Wait, wait, wait. | 13:29 |
| jgriffith | dulek: I'm not even sure that's the path it hit, checking now | 13:29 |
| *** arecknag has joined #openstack-cinder | 13:29 | |
| *** arecknag has quit IRC | 13:29 | |
| dulek | jgriffith: If a volume fails before scheduling, then it was never created on the backend. | 13:29 |
| dulek | jgriffith: And the only moment when host=NULL should be when request never got to c-vol. | 13:30 |
| jgriffith | dulek: so I've found a case where the volume is created.. but I then modify the create call in my driver to raise an error | 13:30 |
| jgriffith | dulek: it's entirely possible/normal to expect that a call can go to the driver, and return an exception BUT that the volume was actually created | 13:30 |
| dulek | jgriffith: Isn't volume.host set by cinder-scheduler? | 13:31 |
| jgriffith | dulek: ie; a resize failed... replication setup failed etc | 13:31 |
| dulek | Let's get one step back. | 13:31 |
| *** arecknag has joined #openstack-cinder | 13:31 | |
| dulek | The path you're showing happens *only* when volume.host=NULL. | 13:31 |
| jgriffith | dulek: no worries... I'll trace through it and figure it out | 13:31 |
| jgriffith | dulek: like I said that may not even be the path I hit :) Could be something else, but that's still bad | 13:32 |
| jgriffith | we've apparantly introduced some fragility somewhere | 13:32 |
| dulek | jgriffith: Okay! I don't think this will be the path you're hitting. | 13:32 |
| jgriffith | dulek: haha... it is :) | 13:33 |
| dulek | jgriffith: So your volume.host is NULL? | 13:33 |
| jgriffith | dulek: indeed | 13:34 |
| jgriffith | and I tihnk it's because the manager catches the exception and bales | 13:34 |
| jgriffith | dulek: without ever updating the object... looking now | 13:35 |
| dulek | jgriffith: But if manager (you mean c-vol) got the request, then volume.host should be set. | 13:35 |
| jgriffith | dulek: indeed, it *should* | 13:35 |
| dulek | jgriffith: It is set just before executing RPC call to c-vol by c-sch or c-api. | 13:35 |
| dulek | jgriffith: Any specifics on how you're creating a volume? | 13:35 |
| jgriffith | dulek: so do this... just modify the last line of driver.create; | 13:36 |
| jgriffith | dulek: have it raise a driver api exception | 13:36 |
| jgriffith | or some random exception | 13:36 |
| jgriffith | *after* actually creating the volume on the backend though | 13:36 |
| dulek | jgriffith: I've added one as last line in create_volume in driver.lvm, restarting services… | 13:37 |
| dulek | jgriffith: uh, oh… | 13:38 |
| jgriffith | dulek: yup | 13:39 |
| dulek | jgriffith: In my case rescheduling happened. Maybe there's a problem. | 13:39 |
| *** knikolla has joined #openstack-cinder | 13:39 | |
| jgriffith | dulek: oh... yeah, that's the other thing I've had distaste on for a couple years | 13:39 |

| *** arecknag has quit IRC | 13:40 | |
| *** haomaiwang has joined #openstack-cinder | 13:40 | |
| jgriffith | which causes a whole host of other issues... like creating a bunch of volumes that now Cinder isn't tracking | 13:40 |
| dulek | jgriffith: Makes sense. We could've identify cases when rescheduling is needed because of race-condition-prone scheduler and reschedule only then. | 13:41 |
| *** iceyao has joined #openstack-cinder | 13:41 | |
| jgriffith | dulek: well... I've always felt it would be *better* to reverse it from a blacklist of retries to a whitelist | 13:42 |
| jgriffith | dulek: so ONLY retry known retryable things as opposed to what we do with "retry anything not on list" | 13:42 |
| jgriffith | although, I thought we did change that | 13:42 |
| jgriffith | perhaps we just need to add another item to the list :) | 13:43 |

| *** mvk_ has quit IRC | 13:52 | |
| jgriffith | dulek: so there's still something fishy though | 13:52 |
| dulek | jgriffith: Yeah, I've just moved the method up to maintain logic order in _pre_rescheduling, rescheduling, _post_rescheduling. | 13:53 |

| mmarin | Hello I'm the French translator for Openstack Cinder and I have a question regarding strings like: "MSG_DENIED: RPC_MISMATCH: %r" | 14:24 |
| smcginnis | mmarin: Hmm, yeah. :) | 14:24 |
| mmarin | Is there anything to translate in here or are those variables that will be replaced by messages | 14:24 |
| smcginnis | mmarin: You can probably just skip those? | 14:24 |
| mmarin | OK we have to have 100% complete by Friday | 14:25 |
| mmarin | so can't skip | 14:25 |
| smcginnis | mmarin: Or MSG_REFUSE ? | 14:25 |
| smcginnis | mmarin: Or MSG_REFUS ? | 14:25 |
| smcginnis | mmarin: But I would probably just leave it as is. That's not really a user friendly string anyway. | 14:26 |
| mmarin | I totally agree with you! | 14:26 |
| smcginnis | mmarin: Cool. Thanks for translating! | 14:26 |
| mmarin | Do you have some time to answer other questions? | 14:26 |
| smcginnis | mmarin: Sure, I can try. | 14:26 |
| mmarin | What does "child usage" mean in the following string ? Sum of child usage '%(sum)s' is greater than free quota of '%(free)s' for project '%(proj)s' for resource '%(res)s'. Please lower the limit or usage for one or more of the following projects: '%(child_ids)s' | 14:27 |
| mmarin | is it the usage by a child device? | 14:27 |
| smcginnis | mmarin: That is for the nested quotas. | 14:27 |
| DuncanT | mmarin: That's for hierarchical quotas | 14:27 |
| smcginnis | mmarin: So there is a "parent" quota that contains one or more "child" quotas. | 14:27 |
| mmarin | Ok great | 14:27 |
| mmarin | that makes sense now! | 14:28 |
| smcginnis | mmarin: Whew, that was an easy one. :) | 14:28 |
| mmarin | Not for the translator believe me, without your explanation it's really a nightmare | 14:28 |
| smcginnis | mmarin: I can imagine! That is an enormous undertaking. | 14:29 |
| mmarin | Should we translate concatenated words or words with underscores or are they keywords like: "consistencygroup assigned" "consistencygroup changed" "glance_metadata changed" | 14:30 |
| mmarin | Should we leave them in English? | 14:30 |
| mmarin | consistencygroup and glance_metadata or they can be translated with space instead of concatenation? | 14:30 |
| *** IlyaG has joined #openstack-cinder | 14:30 | |
| *** liverpooler has quit IRC | 14:31 | |
| smcginnis | glance_metadata may be referring to a field, so that should probably stay. | 14:31 |
| smcginnis | consistencygroup could be broken out to "consistency group" or its translated equivalent. | 14:32 |
| mmarin | ok thanks | 14:32 |
| *** crose has joined #openstack-cinder | 14:32 | |
| mmarin | What does vnr stands for in the following string? DRBDmanage timeout waiting for volume size; volume ID "%(id)s" (res "%(res)s", vnr %(vnr | 14:32 |
| smcginnis | Huh, now you got me. Where is that one located. Maybe I can get some context from the source. | 14:33 |
| mmarin | well I have no context it's in cinder.po file somewhere | 14:33 |
| mmarin | I only have this segment without further context | 14:34 |
| smcginnis | Oh, OK. I'll do a quick search. | 14:34 |
| mmarin | I have other questions that might be easier, I can leave vnr for the moment | 14:34 |

| mmarin | "Option map (cls._map) is not defined." What is an Option map ? | 14:35 |
| mmarin | a map of options? | 14:35 |
| smcginnis | Sounds reasonable. Yeah, I think that is correct. | 14:36 |
| smcginnis | We really have some confusing strings, don't we? :) | 14:36 |
| geguileo | mmarin: vnr stands for volume number | 14:36 |
| geguileo | mmarin: It's something specific to that driver | 14:37 |
| mmarin | ok so I will leave it as is | 14:37 |
| geguileo | mmarin: Yes, I think it's best | 14:37 |
| mmarin | Is portgroup translatable or not in the following string? "Cannot get the portgroup from the masking view." | 14:39 |
| *** adisky has quit IRC | 14:40 | |
| mmarin | sometime we have portgroup, sometime port group, for translators when words are concatenated they suppose to be keywords and are not translated will that rule applies here? | 14:40 |
| *** IlyaG has quit IRC | 14:40 | |
| *** andymaier has joined #openstack-cinder | 14:40 | |

| jgriffith | smcginnis: that's not one of mine | 16:56 |
| smcginnis | jgriffith: I wonder if that's left over cruft from some interim repl work. | 16:56 |
| mmarin | I wish I were a developer to understand all this code... so can you actually split a replication? | 16:56 |
| smcginnis | mmarin: That appears to be a vendor specific thing. | 16:57 |
| *** tongli has joined #openstack-cinder | 16:57 | |
| smcginnis | mmarin: So if you're going to translate that, think the action of splitting a replication failed. | 16:58 |
| smcginnis | My best guess at least. | 16:58 |
| jgriffith | smcginnis: mmarin diablo_rojo that's an internal huawei method | 16:58 |
| jgriffith | and log statement | 16:58 |
| jungleboyj | Looking at the code it looks like they are trying to separate the replication relationship before failing over to the replica. | 16:59 |
| jgriffith | it's defined by their internal AbsReplicaOp parent class | 16:59 |

| dulek | jgriffith: It's because of capacity tracking - in case of rescheduling we're not increasing it and we want not to decrease it when deleting. | 18:27 |
| jgriffith | dulek: meh... yeah, I can see that | 18:27 |
| jgriffith | dulek: but while were' "in" a request I think it's ok to error on the side of caution and assume we've allocated/used the storage | 18:28 |
| dulek | jgriffith: I was thinking about that and it seems like a broken model - we cannot do both things accurately. | 18:28 |
| jgriffith | dulek: even worse in this case we do in fact allocate it (3 times) | 18:28 |

| dulek | jgriffith: You've wrote that more than a year ago. ;) | 18:31 |
| jgriffith | dulek: yes! That's why I said my head might explode | 18:31 |
| jgriffith | dulek: I actually still remember clearly the day I was working on that | 18:32 |
| jgriffith | dulek: it was VERY frustrating for me to try and make things work correctly in our model | 18:32 |
| dulek | I guess you were surprised your head survived that? ;) | 18:32 |
| jgriffith | dulek: and as you see I punted and gave up, because my best proposal was to rewrite the whole mess | 18:32 |
| jgriffith | dulek: LOL.. yes! | 18:33 |
| dulek | jgriffith: So let me sleep with that, I'll try to get all of my thoughts on that in a neat bugreport tomorrow in the morning. | 18:33 |
| jgriffith | dulek: fair enough | 18:34 |
| dulek | jgriffith: And maybe the problem is worthy of a discussion at the working session in Austin. | 18:34 |
| jgriffith | dulek: well... perhaps (been there done that) | 18:34 |

| dulek | jgriffith: You can ping me if you come up with a partial fix, but I really need to get off work for today (7:30 PM here). | 18:36 |

| alkhodos | Hi guys, there was a recent patch for Nexenta driver (unfortunately I didn't notice the bug myself) https://review.openstack.org/#/c/295304/ and yesterday our CI started to fail with this error http://paste.openstack.org/show/491639/.

| *** IlyaG has quit IRC | 21:23 | |
| smcginnis | alkhodos: That actually looks like a new one. | 21:23 |
| smcginnis | alkhodos: There was the issue that cloning a volume could be a larger size. | 21:23 |
| *** david-lyle has joined #openstack-cinder | 21:23 | |
| smcginnis | alkhodos: That was that patch referred, and your CI appears to be happy with that one. | 21:24 |
| smcginnis | alkhodos: There's a second new one that's similar but different. | 21:24 |
| alkhodos | smcginnis: yes, I understand the reasoning for the patch, but that's the only place where the driver call volume['size'] | 21:24 |
| smcginnis | alkhodos: That's for creating a volume from snapshot. | 21:24 |
| smcginnis | The paste appears to be related to that. | 21:24 |
| smcginnis | There is a check that volume has size, but not that snapshot has size. | 21:24 |
| smcginnis | alkhodos: Is the failing patch on a fix for that one? | 21:25 |
| *** ociuhandu has joined #openstack-cinder | 21:25 | |
| alkhodos | smcginnis: from some point it fails all the patches, so looks like some merged patch is the reason | 21:26 |
| smcginnis | alkhodos: Odd, I didn't think any of those snapshot ones went through yet. | 21:27 |
| smcginnis | Looking... | 21:27 |
| smcginnis | alkhodos: You are right, that snapshot['size'] check was from the clone size fix. | 21:29 |
| alkhodos | smcginnis: I should probably add a 'size' in snapshot check ? | 21:30 |
| smcginnis | Not sure why snapshot doesn't have size. | 21:30 |
| smcginnis | It's possible it is only passed in if a new size is specified. | 21:30 |
| smcginnis | alkhodos: If that's the case, it could be safe to change it from snapshot['size'] to snapshot.get('size', 0) | 21:31 |
| smcginnis | In fact, line 326 could probably just be changed to "if volume.get('size', 0) > snapshot.get('size', 0)" | 21:32 |
| alkhodos | smcginnis: but in that case if volume has size and snapshot doesn't, we will always call extend | 21:32 |
| smcginnis | alkhodos: Oh, right. :] | 21:33 |
| alkhodos | smcginnis: doesn't look like correct workflow :) | 21:34 |
