Swanson | xyang, backup volume support? I did not override the base on that one. It didn't look like I needed to. Am I incorrect? | 18:11 |
hemna | smcginnis, shouldn't there be a spec on this | 18:11 |
hemna | this seems to be duplicating fields in the db | 18:11 |
hemna | I can see this causing all sorts of confusion | 18:12 |
*** alonma has quit IRC | 18:13 | |
smcginnis | hemna: Using enums seemed to be a good thing. I didn't think it was a big enough change to need a spec, but if you think that's an issue, I certainly don't think it would hurt. | 18:13 |
hemna | well | 18:14 |
smcginnis | hemna: Very possible I don't understand all the implications of this. | 18:14 |
hemna | the problem is now we'll have multiple fields in the DB and the object to store the same data. | 18:14 |
hemna | :( | 18:14 |
hemna | maybe I'm paranoid, but this seems like a source of future pain. | 18:14 |
smcginnis | hemna: Upgrades are probably an issue too, aren't they? | 18:14 |
hemna | yah could be | 18:15 |
hemna | maybe I have this wrong, dunno. | 18:15 |
hemna | would be nice to get some clarification on it though. | 18:15 |

hemna | yah cool with me | 18:24 |
hemna | I was worried it was a new DB field | 18:24 |
hemna | but that's what I get for reading the commit message. | 18:24 |
jungleboyj | No. It is going to take some work to get things switched over but should be better in the long run. | 18:25 |
hemna | so we just have to be careful because Nova isn't using any enums to access status fields. | 18:26 |

ildikov | hemna: have you seen the comment I added on the Nova part of that detach Cinder bug fix? | 18:29 |
dulek | hemna: Ah, good point on Nova. Maybe we should add an module with enums to the client? That would be hard to keep in sync tough… | 18:29 |

hemna | The struggle is strong with this one. | 18:31 |
jungleboyj | hemna: So, I am thinking that they would eventually be moving there. Ryan, who submitted the patch, is a Nova guy. :-) | 18:31 |
*** openstackgerrit has quit IRC | 18:32 | |
hemna | dulek, maybe we can eventually send the versioned objects over the wire to nova in a different api. | 18:32 |
hemna | meh | 18:32 |
hemna | that also sounds like pain though. | 18:32 |

hemna | everyone is back. how many patches can we cram in...now! | 18:33 |
dulek | hemna: Nova would need to import our versioned objects. Not sure if Nova is importing cinder code anywhere? | 18:33 |
*** alonma has joined #openstack-cinder | 18:34 | |
e0ne | dulek: it shouldn't import cinder directly. everybody must use cinderclient | 18:34 |
jungleboyj | hemna: Thanks for -1'ing and then merging. :-) Happy New Year. | 18:35 |
dulek | e0ne: Sure, that's how I thought it should be. | 18:35 |
hemna | :) | 18:35 |
hemna | dulek, it's not | 18:35 |
hemna | dulek, there was a short discussion a while back about adding versioned objects to brick as well, since the contract between cinder and brick as well as nova and brick should be more contractual | 18:36 |
hemna | right now it's just dicts that are supposed to have the right things. | 18:36 |
hemna | that's a cross project issue that we all should chew on | 18:37 |
hemna | kinda the same problem really. | 18:37 |
*** alonma has quit IRC | 18:38 | |

dulek | xyang: Without my patch this line does nothing, as volume_metadata isn't an alias, so isn't actually setting anything. | 18:47 |

xyang | oh, let me see | 18:48 |
*** sasukeh has joined #openstack-cinder | 18:48 | |
dulek | xyang: Now with my patch test starts to fail - as "volume['volume_metadata'] = sth" starts to do something meaningful. | 18:48 |
hemna | gah | 18:48 |
hemna | back to this horrible gerrit UI | 18:48 |
hemna | how do you do a search in the page now ? | 18:49 |
dulek | xyang: That's why I believe there's logical mistake either in test (hopefully) or driver logic. | 18:49 |

*** ntpttr has quit IRC | 18:50 | |
hemna | holy crap, I didn't realize that bug until now | 18:50 |
dulek | hemna: Hm, you may see if setting render to "slow" doesn't make it load all the code at once. | 18:50 |

*** alonma has quit IRC | 18:50 | |
hemna | patrickeast, yah it's not working for me at all | 18:51 |
dulek | hemna: You go to diff view settings using this little clockwork on the right. | 18:51 |
smcginnis | dulek: Oh, didn't realize that was a setting! | 18:51 |
smcginnis | dulek: Seems a pretty minimal memory advantage not to load all the code at once. | 18:51 |

*** alonma has quit IRC | 19:03 | |
smcginnis | rlrossit: I think we worked it out. | 19:03 |

smcginnis | rlrossit: My one remaining doubt was whether there was any kind of upgrade implication from this. | 19:04 |
dulek | xyang: This will help, I think. So with snapcopy=True your driver is supposed to use snap-as-vol as snapshot names? Should I add that fix into my patch or should we have an additional one? | 19:05 |
sheel | hemna:just ctrl+f and type searchWord , then press n for recurring search like we do in vim | 19:06 |
rlrossit | smcginnis: there are some, but no more than the versioned objects bring with them (basically these enums should be additive so you don't pull the rug out from anyone) | 19:06 |

sheel | hemna:hope it answers to your query | 19:07 |
dulek | We should be able to backport such object - will automated ovo version bump tests detect enum change? | 19:07 |
hemna | sheel, yah that wasn't working, and I couldn't get it to allow chrome's search to work either. | 19:08 |
* hemna is so not a fan of the new gerrit UI. It's broken in so many ways. | 19:08 | |
rlrossit | dulek: if you change an enum, that will change the object hash, so that will suggest a version bump | 19:08 |
rlrossit | dulek: if you're also implying actual backport code, that gets tougher | 19:09 |
sheel | hemna:oh, something strange.. | 19:09 |
* rlrossit searches quickly for a nova example | 19:09 | |
* dulek needs to test ovo version bump test fixture by himself… | 19:10 | |
xyang | dulek: I think there are some problems in the unit tests. I don't know why yours can't pass while the snapcopy feature can pass unit tests. I'll ask the VNX guys to double check. | 19:10 |

e0ne | sheel: one more question to make me on the same page:) | 20:10 |
e0ne | sheel: why do we need 'elif read_deleted == 'int_no'"? | 20:10 |
e0ne | https://review.openstack.org/#/c/255947/12/cinder/db/sqlalchemy/api.py - it looks too compltaced now | 20:10 |
sheel | e0ne: its too handle read_deleted for integer instead of boolean | 20:12 |
e0ne | sheel: can we use something like oslo_utils.strutils.bool_from_string there? | 20:12 |

e0ne | sheel: quick question inline. I remove my -1 once I'll get unswer | 20:16 |

hemna | https://review.openstack.org/#/c/255595/4/cinder/api/contrib/volume_actions.py | 21:42 |
ildikov | or at least will not really be backward compatible, I mean no upgrade path, etc. | 21:42 |
*** cknight has quit IRC | 21:42 | |
ildikov | cool, I remembered that part, but I wonder if it's not an issue that Nova then will work only with the latest Cinder | 21:43 |
hemna | yah I think so | 21:43 |
*** dustins has quit IRC | 21:44 | |
hemna | well at least multi-attach | 21:44 |
*** ndipanov has quit IRC | 21:45 | |
ildikov | you mean to pass it only in case of multi-attach | 21:45 |
hemna | I don't think so | 21:47 |
hemna | I figure lets be consistent | 21:47 |
hemna | the host_name field is there, we just never pass it from nova | 21:47 |
hemna | I think only cinder adds it when it attaches a volume to itself, when there is no instance_uuid | 21:47 |
scottda | hemna: I think Ivan's patches for attach-without-nova also uses host_name | 21:48 |
*** alonma has joined #openstack-cinder | 21:48 | |
ildikov | but that check is already there, I wonder how we can do it in an acceptable way | 21:48 |
hemna | scottda, yah that would make sense | 21:49 |
hemna | ildikov, I'm not sure really | 21:49 |
hemna | any change is going to be an issue I think | 21:50 |
ildikov | hemna: that's kinda sad :( | 21:50 |
hemna | :( | 21:50 |
hemna | I don't know what else to do. | 21:50 |
ildikov | but anyway, my bugfix patch depends on yours anyways | 21:50 |
ildikov | so let's get yours in and then we can fix this bug on Nova side later and add docs about it until | 21:51 |
hemna | looks like I need to push up another patch to address some small things that john pointed out. | 21:52 |
openstackgerrit | Patrick East proposed openstack/cinder-specs: Propose new admin action to set replication status https://review.openstack.org/263444 | 21:52 |
hemna | this whole interaction between nova and cinder just feels like a house of cards at this point. | 21:53 |
*** alonma has quit IRC | 21:53 | |
openstackgerrit | Alex O'Rourke proposed openstack/cinder: Change minimum 3PAR API version for replication https://review.openstack.org/263458 | 21:53 |

*** mragupat_ has joined #openstack-cinder | 21:58 | |
*** haomaiwang has quit IRC | 22:01 | |
ildikov | hemna: yeah, I have that feeling nowadays very often | 22:01 |
ildikov | although just simply about this multiattach feature | 22:01 |
*** haomaiwang has joined #openstack-cinder | 22:01 | |
hemna | ok | 22:01 |
*** mragupat has quit IRC | 22:01 | |
ildikov | I started to read about the hypervisors and I'm not 100% sure how it will work | 22:01 |
hemna | so I think at a minimum we should raise this in the next Cinder meeting | 22:02 |
*** alonma has quit IRC | 22:02 | |
ildikov | and Nova code is a bit of a mess too at least for a new comer like me | 22:02 |
hemna | I think that's almost always the case there.... | 22:02 |
hemna | :P | 22:02 |
ildikov | this bug fix issue you mean? | 22:02 |
hemna | my original nova patch was a mess too. | 22:02 |
hemna | ildikov, yah | 22:02 |
ildikov | I will not disagree :) | 22:02 |
ildikov | ok, when is that meeting? | 22:03 |
hemna | Wed. | 22:03 |

hemna | np | 22:08 |
*** alexpilotti_ has joined #openstack-cinder | 22:08 | |
ildikov | Nova non-prio feature deadline is also pretty close | 22:09 |
ildikov | I'm trying to get review attention, but it will still be tough | 22:09 |
hemna | so, does that mean all of the nova patches have to land before that? | 22:09 |
ildikov | do you know anyone to ask? | 22:09 |
hemna | do you know what the deadline date is ? | 22:09 |
ildikov | Jan 21 IIRC | 22:09 |
hemna | ildikov, you can ask mriedem | 22:09 |
hemna | 21st ok | 22:10 |
hemna | that gives us a little wiggle room | 22:10 |
ildikov | ok, will do | 22:10 |
ildikov | I have a +2 on the first patch, the problem comes with the second one as we call out to Cinder every time for the attachment_id as it currently not stored in Nova | 22:10 |
hemna | url ? | 22:11 |
ildikov | if it would be stored that requires another DB round, with db_migrate I guess, many new things... | 22:12 |
ildikov | https://review.openstack.org/#/c/193134/49 | 22:12 |
*** akerr has joined #openstack-cinder | 22:13 | |
*** zhonghua-lee has quit IRC | 22:13 | |
*** merooney has joined #openstack-cinder | 22:13 | |
*** zhonghua-lee has joined #openstack-cinder | 22:14 | |
mriedem | so the round trip issue is in https://review.openstack.org/#/c/193134/ | 22:14 |
mriedem | there was a spec at one point to store the volume attachment id in the nova bdm table | 22:14 |
hemna | oh you mean get_attachment_id inside of detach ? | 22:14 |
mriedem | b/c the attach api currently returns the volume id for both the volume id and attachment id, which is misleading | 22:14 |
ildikov | yeah, it was moved there recently | 22:14 |
*** akerr_ has joined #openstack-cinder | 22:14 | |
hemna | mriedem, ? | 22:15 |
ildikov | mriedem: TBH it's in the multiattach spec at the moment that Nova does not store the attachment_id | 22:15 |
*** salv-orl_ has quit IRC | 22:15 | |
ildikov | it was accepted that way | 22:15 |
mriedem | this https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/volumes.py#L203 | 22:15 |
hemna | that stuff has been around for ages | 22:16 |
mriedem | right | 22:16 |
ildikov | people were more comfortable with that version | 22:16 |
mriedem | and that's why we nixed a spec asking to change that | 22:16 |
mriedem | b/c it would have required a db migration and an api microversion and no one really saw the need | 22:16 |
mriedem | since you can get the attachments from the volume api | 22:16 |
mriedem | and we have this policy about no new api proxy | 22:17 |
mriedem | like george bush and no new taxes | 22:17 |
hemna | heh | 22:17 |
*** eharney has quit IRC | 22:18 | |
mriedem | so it would appear there is a reason to have it now | 22:18 |
hemna | looking back at my original nova patch, I had get_volume_attachment as a callable method in cinder.py | 22:18 |
*** diablo_rojo has quit IRC | 22:18 | |
*** akerr has quit IRC | 22:18 | |
ildikov | so volume_id is used there as earlier there was no attachment_id or? | 22:18 |
mriedem | right, so john's concern in https://review.openstack.org/#/c/193134/ is having to back to get that all the time | 22:18 |
mriedem | ildikov: nova only stores the volume id | 22:18 |
hemna | https://review.openstack.org/#/c/85852/2/nova/compute/manager.py | 22:19 |
hemna | my old patch | 22:19 |
hemna | it does make a call to fetch the volume, then get the attachment id | 22:19 |
ildikov | mriedem: yeah, sorry, I missed that it's the translation function | 22:19 |
hemna | I didn't see a way of getting around it w/o nova db changes :( | 22:19 |
mriedem | yeah i see the method added here https://review.openstack.org/#/c/85852/2/nova/volume/cinder.py | 22:20 |
hemna | and honestly, I'm a bit worried about storing cinder stuffs inside of nova | 22:20 |
hemna | it seems to be a breakdown of the contract | 22:20 |
*** mriedem is now known as mriedem_jedi | 22:20 | |
hemna | cinder should be the source of truth | 22:20 |
hemna | :) | 22:20 |
mriedem_jedi | yeah, like the attachment status snafu's | 22:21 |
mriedem_jedi | that andrea was trying to address | 22:21 |
ildikov | hemna: for volume info I have to agree :) | 22:21 |
*** mriedem_jedi is now known as mriedem | 22:21 | |
hemna | mriedem, yup. | 22:21 |
hemna | so, that induces a round trip. | 22:21 |
mriedem | hemna: for neutron there is the network info cache on the instance | 22:21 |
mriedem | which is also racy | 22:21 |
hemna | yup | 22:22 |
mriedem | but it gets updated in a periodic task and on network operations on the instance | 22:22 |
hemna | lol, just have nova access the cinder db directly. | 22:22 |
hemna | problem solved. | 22:22 |
hemna | :P | 22:22 |
hemna | thank you, I'll be here all week. | 22:22 |
ildikov | how much will this be a performance issue? | 22:22 |
*** akerr_ has quit IRC | 22:23 | |
hemna | it's 1 extra round trip at detach time. | 22:23 |
ildikov | sorry for the dumb questions, getting late here and it's the first Monday of the year for 37 minutes still :) | 22:23 |
hemna | I think there were cases in nova that it already had the volume object and it didn't have to do the round trip | 22:23 |
hemna | hrmm | 22:24 |
ildikov | you mean I should check these round trips and see whether I might already have the info | 22:24 |
hemna | maybe I'm wrong on that one | 22:24 |
hemna | yah | 22:24 |
mriedem | was just reading john's comments in https://review.openstack.org/#/c/193134/32/nova/compute/manager.py | 22:25 |
mriedem | i haven't been reviewing this series so i'm out of context here | 22:25 |
mriedem | but i remember that other spec about wanting to store the attachment id | 22:25 |
hemna | which comment ? | 22:25 |
hemna | sorry just trying to follow | 22:25 |
ildikov | there was one version of the multiattach spec or at least comments about it | 22:25 |
*** alexpilotti_ has quit IRC | 22:26 | |
ildikov | but even if it made it into that particular spec it did not last long I'm sure | 22:26 |
hemna | oh I see what he's saying | 22:27 |
hemna | in the rpc call into the manager | 22:27 |
*** jungleboyj has quit IRC | 22:27 | |
hemna | you might already have pulled the cinder volume object, and hence had the attachment_id to pass in the rpc call | 22:27 |
hemna | if that's the case, then yah that'd be better | 22:27 |
hemna | I don't know that call chain very well, so we'd have to find that out | 22:27 |
mriedem | yeah so you get the volume from cinder in n-api and pass the attachment id over rpc to compute, | 22:29 |
ildikov | yeah, I might need some help on that one | 22:29 |
ildikov | also isn't RPC versioned too in some way? | 22:29 |
hemna | mriedem, yah I think that'd work. | 22:29 |
mriedem | if compute doesn't get the attachment id, it's pre-mitaka code and compute has to go to cinder again | 22:29 |
mriedem | ildikov: yea rpc is versioned | 22:29 |
mriedem | you'd be passing a new kwarg | 22:29 |
openstackgerrit | Sean McGinnis proposed openstack/cinder: Revert "Rebrand HP XP driver to now be HPE" https://review.openstack.org/263467 | 22:29 |
mriedem | https://github.com/openstack/nova/blob/master/nova/compute/rpcapi.py#L470 | 22:30 |
mriedem | so we're talking about adding an attachment_id kwarg to that right? | 22:30 |
mriedem | if the client version is < 4.7, you wouldn't send that kwarg | 22:31 |
hemna | yah | 22:31 |
mriedem | b/c older compute wouldn't understand | 22:31 |

*** e0ne has joined #openstack-cinder | 22:34 | |
mriedem | this is a better example https://github.com/openstack/nova/blob/master/nova/compute/rpcapi.py#L670 | 22:34 |
mriedem | where it's checking the version and popping kwargs | 22:34 |
ntpttr1 | I'm not sure if it's just me locally, but since I got back from holiday tox isn't working for me on the master branch of cinder, because it fails to import tooz.coordination in cinder.tests.unit.test_coordination. Is this happening with anyone else, or is there something else I have to update? | 22:35 |
ildikov | mriedem: ok, thanks | 22:37 |
*** baumann has left #openstack-cinder | 22:39 | |
ildikov | mriedem: I will check the Nova API calls and then modify that patch accordingly | 22:40 |
ildikov | I might annoy you with stupid questions on the go, but will try not to | 22:41 |
ildikov | thanks for the pointers | 22:41 |
*** rlrossit has quit IRC | 22:41 | |
mriedem | ildikov: hemna: alternatively, there is always the bdm.connection_info bag of goodies that's stored in the nova db | 22:46 |
mriedem | it's just a json blob | 22:46 |
mriedem | unversioned | 22:46 |
ildikov | I saw that there is, but I didn't know it's unversioned | 22:46 |
mriedem | but it's a way to stash an attachment id on attach, and look it up on detach | 22:46 |
mriedem | it's mostly just what nova gets back from calling os-initialize_connection | 22:47 |
hemna | yah, that's kinda a dump | 22:47 |
*** akerr has quit IRC | 22:48 | |
hemna | but I believe that's populated prior to calling cinder's attach | 22:48 |
ildikov | mriedem: there's a _local_delete function which calls the volume_api to detach in compute api: https://github.com/openstack/nova/blob/master/nova/compute/api.py#L1833 | 22:48 |
hemna | the cinder attach is the last call in the chain (updates cinder's DB record) | 22:48 |
*** akerr has joined #openstack-cinder | 22:49 | |
mriedem | ildikov: _local_delete is a separate delete path | 22:49 |
mriedem | that doesn't go through the compute manager | 22:49 |
mriedem | in special cases | 22:49 |
hemna | also, fwiw, the connection_info blob gets blown away during live migration time | 22:49 |
mriedem | like if the service is down | 22:49 |
hemna | well, recreated | 22:49 |
mriedem | hemna: yeah, that's another bug i think that was never fixed, | 22:50 |
mriedem | i.e. stashing off the 'old' connection info to use in case live migration fails and we need to rollback | 22:50 |
hemna | yup | 22:50 |
ildikov | in that case I assume we will need to retrieve the attachment id from Cinder then | 22:50 |
mriedem | it's actually listed as security bug | 22:50 |
hemna | huh, no kidding | 22:50 |
hemna | makes sense I guess. | 22:50 |
hemna | ildikov, yes | 22:50 |
mriedem | hemna: well, not one that anyone is fixing | 22:51 |
mriedem | 'during live migration, gain root access to the host and make live migration fail...' | 22:51 |
mriedem | etc etc | 22:51 |
mriedem | so there is a bug for the rollback case, but the security bug wasn't a priority | 22:51 |
mriedem | anywho, have to run | 22:56 |
