dulek | Will/Does nova support multi-attach cinder volumes yet? | 14:05 |
dulek | M? No. | 14:05 |

scottda | smcginnis: Well, that does lead to some questions about priorities in O | 14:07 |
dulek | We don't want any riots, do we? ;) | 14:07 |
scottda | Short release, and focus on testing/stability, but we've in-flight AA/HA, multi-attach, and cinder-nova API changes. Hopefully, that's not too much. | 14:07 |
smcginnis | scottda: I consider the attach/detach stuff work in progress that we need to finish up. As part of the "stabilization" part. ;) | 14:08 |
guitarzan | I'm just waiting for the data corruption riots myself :) | 14:08 |
smcginnis | guitarzan: That will come next. :D | 14:08 |

msno | in an openstack mitaka based setup.. i am not able to create a snaphot of an instance which is booted from volume | 14:19 |
*** salv-orlando has joined #openstack-cinder | 14:20 | |

openstackgerrit | Eric Harney proposed openstack/os-brick: test https://review.openstack.org/378665 | 14:20 |
eharney | well that wasn't supposed to go there... | 14:20 |
smcginnis | eharney: Hah | 14:21 |
smcginnis | msno: What are you using for your backend storage? Any logs to look at? | 14:21 |
msno | smcginnis, backend storage is VSA | 14:22 |
msno | i wanted to know igf its a expected behavior | 14:22 |
msno | i am not taking an volume snapshot of the boot from volume .. volume | 14:22 |
msno | instead a instance snapshot | 14:22 |
smcginnis | msno: Oh? Might want to ask on #openstack-nova then. But I believe that's expected to work. | 14:23 |
msno | smcginnis, ok.. i checked in openstack-nova though | 14:23 |
*** Julien-zte has quit IRC | 14:24 | |
johnthetubaguy | that sounds correct btw, the glance snapshot just references the volume snapshot | 14:24 |
johnthetubaguy | you would have to do a volume export into glance to get the data bits into glance | 14:24 |
*** Julien-zte has joined #openstack-cinder | 14:24 | |
johnthetubaguy | you should be able to boot another nova instance from that snapshot, and it does boot from volume, but I don't 100% remember | 14:25 |

*** lprice1 has joined #openstack-cinder | 14:26 | |
msno | johnthetubaguy, hmm.. interesting .. here the snapshot is not even getting created .. | 14:26 |
johnthetubaguy | glance v2 actually gets a bit confusing around that, as we have to give it a fake container and volume type to keep their schema checking happy | 14:26 |
*** bks has joined #openstack-cinder | 14:27 | |
johnthetubaguy | msno: what errors are you seeing? | 14:27 |
msno | not in cinder snapshot-list and in nova snapshot-list | 14:27 |
msno | let me check.. but what i wanted to know is.. | 14:27 |
johnthetubaguy | nova snapshot-list is probably not what you think it is | 14:27 |
msno | its suppose o work .. right? | 14:27 |
johnthetubaguy | it should appear in glance image-list | 14:27 |
*** gsilvis has joined #openstack-cinder | 14:28 | |
*** diablo_rojo has joined #openstack-cinder | 14:28 | |
johnthetubaguy | msno: more info in here on the current state of that snapshot API: http://developer.openstack.org/api-ref/compute/#volume-extension-os-volumes-os-snapshots-deprecated | 14:28 |
msno | johnthetubaguy, yes.. you are right.. in glance image-list its showing this snapshot .. and its zero size | 14:29 |
*** lprice has quit IRC | 14:29 | |
johnthetubaguy | thats expected | 14:29 |
msno | but i will be still able to launch an instance .. right? | 14:29 |
johnthetubaguy | it should have metadata that points to the cinder snapshot | 14:29 |
johnthetubaguy | and that gets used by nova a boot time to create your disk | 14:29 |
msno | got it.. ok.. so if i want to take a backup of this .. can i just try doing a glance image download of this snapshot | 14:30 |
*** sudipto has quit IRC | 14:30 | |
*** sudipto_ has quit IRC | 14:30 | |
msno | i guess .. it wont work | 14:30 |
johnthetubaguy | right, you can't use glance to download those snapshots | 14:31 |
johnthetubaguy | but it should tell you what the cinder snapshot uuid is, so you can export it from cinder | 14:31 |

*** crose has quit IRC | 14:32 | |
*** crose has joined #openstack-cinder | 14:32 | |
msno | johnthetubaguy, in that case.. i have to detach this volume from nova .. since its in attached-state .. take a cinder volume snapshot..which adds it to glance .. then download it from glance ? | 14:32 |
msno | afaik | 14:33 |
johnthetubaguy | it shouldn't need all that | 14:33 |
msno | else .. just take the lun backup of the volume from VSA and use it in another cloud | 14:33 |
johnthetubaguy | the snapshot should have already been taken | 14:33 |
msno | oh ok.. | 14:33 |
*** lennyb has quit IRC | 14:34 | |
johnthetubaguy | its uuid should be attached to the glance image as metadata | 14:34 |
msno | yes.. now i can see the cinder snapshot which matches the UUID .. to glance image-list data of snapshot | 14:35 |
msno | so what should i do with the conder volume .. which is a snapshot | 14:35 |
*** sudipto has joined #openstack-cinder | 14:37 | |
*** sudipto_ has joined #openstack-cinder | 14:37 | |

*** chris_morrell has joined #openstack-cinder | 14:40 | |

*** tgtanya has quit IRC | 15:07 | |

*** kfarr has quit IRC | 15:08 | |
scottda | dulek: I think it was decided when we re-elected smcginnis , who campaigned saying that's what he envisioned for O? | 15:08 |
smcginnis | dulek: Decided. ;) | 15:08 |
scottda | See? What Great Leader said^^ | 15:08 |
smcginnis | scottda: And yes, that will be important. I'm hoping to add some plans there. | 15:08 |
* smcginnis is in another meeting as usual right now... | 15:09 | |
*** tgtanya_ is now known as tgtanya | 15:09 | |

smcginnis | LOl | 15:09 |
scottda | geguileo: I think test efforts for AA/HA are important for getting it all merged into O. | 15:09 |
geguileo | scottda: I agree | 15:09 |
geguileo | scottda: I'm now banging my head against my desk to make replication work in A/A environments | 15:10 |

geguileo | scottda: I'll try to get it fixed this week and update the post | 15:11 |
geguileo | scottda: But we have to decide how we want to test this | 15:11 |
geguileo | On a conceptual level I mean | 15:11 |
scottda | geguileo: We had great success merging a bunch of a/a patches at the midcycle. I think we should be prepared for another round of that at the summit. | 15:11 |
geguileo | scottda: That would definitely make me happy :-) | 15:11 |
dulek | scottda: +1! | 15:12 |
*** adisky has quit IRC | 15:12 | |
scottda | Yeah, testing A/A has proven to be tricky. Your manual steps are great, but we need efforts to do more of the automation, etc. | 15:12 |
* scottda is guilty of not spending time on A/A tests. | 15:12 | |
geguileo | scottda: Yeah, automation is key | 15:12 |
geguileo | scottda: But we have to decide to what level we want to test it | 15:13 |
scottda | geguileo: Well some things are probably out of scope, like the idea of error-injection. | 15:13 |
geguileo | scottda: Out of the scope of the initial tests or in general? | 15:13 |
scottda | That will probably have to come later, and start in someone's lab. | 15:14 |
scottda | Just outside initial tests. | 15:14 |
scottda | I think if we gate the merge of AA patches on those tests, we won't get it in O | 15:14 |
scottda | just my opinion. | 15:14 |
*** tgtanya has quit IRC | 15:15 | |
scottda | It seems within reach to create basic functional tests, running in a multi-node cinder devstack. | 15:15 |
scottda | I would guess start with the experimental jobs. | 15:16 |
geguileo | scottda: Sounds reasonable to me | 15:16 |
geguileo | scottda: So we should create test cases we'll cover initially | 15:17 |
geguileo | scottda: But I'm not so sure how we'll test that the A/A part is actually working | 15:17 |
scottda | yeah, that is tricky... | 15:18 |
scottda | Of course some of the testing is that normal operations don't get broken. We get that for free just having the A/A code running. | 15:20 |
dulek | Why don't we get same tactic like with rolling upgrades? It's experimental until we've set up CI testing it? | 15:21 |
scottda | I think the worrisome parts are around failure cases and cleanup. i.e. could we accidentally have a volume attached to 2 instances. | 15:21 |
openstackgerrit | David Sariel proposed openstack/cinder: Hacking checks for H105 https://review.openstack.org/377714 | 15:21 |
scottda | dulek: Yes, that seems like the right path. | 15:21 |
openstackgerrit | David Sariel proposed openstack/cinder: Hacking checks for H105 https://review.openstack.org/377714 | 15:21 |
dulek | The only problem would be that it can break something that's working already, but well… This means our Tempest tests set is too narrow. | 15:22 |
openstackgerrit | Bartek Żurawski proposed openstack/cinder: Add volume type name into volume notification https://review.openstack.org/378700 | 15:22 |
scottda | dulek: Right. IF our tempest coverage were complete, we'd at least know that we hadn't broken anything. | 15:22 |
*** arecknag has quit IRC | 15:23 | |
*** xek__ has joined #openstack-cinder | 15:23 | |
scottda | But what about the idea of what worries people have? Is there anything besides the data corruption case where a mistake in cleanup of 'attaching' or 'detaching' volumes results in an unwanted multi-attach? | 15:24 |
dulek | Yeah, but what I mean is that we're breaking stuff that's not tempest-tested all the time anyway. Getting A/A early in Ocata is the best course of action for us. | 15:24 |
scottda | I've had a hard time thinking of other bad scenarios. | 15:24 |
scottda | dulek: +1 to getting it in early | 15:24 |

*** jungleboyj has joined #openstack-cinder | 15:28 | |
scottda | I don't want to wait for Barcelona to start this discussion with the wider community. | 15:28 |
geguileo | scottda: Yes, I think it's a great idea | 15:28 |
*** tgtanya has joined #openstack-cinder | 15:29 | |
scottda | And, yes, I think if, as a community, we were committed to getting this in the O release, we should get it in soon. Like, before the Summit. | 15:29 |
geguileo | scottda: I agree, we want it asap so we can detect bugs, corner cases, etc. | 15:29 |
geguileo | Otherwise it's only going to get half in | 15:29 |
DuncanT | If we merge very early in the cycle, we've plenty of time to fix things up. Hopefully we'll have some initial testiing results for the summit.... those are far more interesting than reitterating plans | 15:29 |

dulek | Big red bar is the moment when scheduling of typeless volumes was broken - this job creates typeless volumes actually. | 15:33 |
scottda | dulek: Looks good. Are you proposing making it voting? | 15:33 |
dulek | scottda: Yup, I'll send an email to openstack-dev soon unless someone has an objection. | 15:34 |
erlon | dulek: is it possible to add other jenkins jobs in the graph to compare? | 15:34 |

msno | smcginnis, does 'cinder snapshot-unmanage ' and 'cinder snapshot-manage' work for copying a cinder snapshot to another setup? | 15:49 |
*** kumarb has quit IRC | 15:50 | |
*** bks has joined #openstack-cinder | 15:51 | |
smcginnis | msno: No, those are for bringing in a snapshot created outside of cinder to have it now managed by cinder and vice versa. | 15:52 |
DuncanT | msno: Only if both cinders share the same storage backend (not the backend type, the same single physical array) | 15:52 |
*** akapil_ has joined #openstack-cinder | 15:53 | |
DuncanT | msno: You can use backup and backup export / import to move volumes between installations, but the performance might leave something to be desired | 15:54 |
*** alonma has quit IRC | 15:54 | |
msno | DuncanT, i just tried 'cinder backup-create ' on a cinder snapshot and it failed.. but when i did it in a actual volume .. its working .. expected? | 15:55 |
DuncanT | msno: What version of cinder? Backing up snapshots should work | 15:55 |
*** akapil_ has quit IRC | 15:56 | |
msno | DuncanT, ok.. i will check it .. let me try the export stuff.. which i should do after the 'cinder create-backup' .. right? | 15:56 |
*** akapil has quit IRC | 15:56 | |
*** akapil has joined #openstack-cinder | 15:56 | |
DuncanT | msno: When the backup is listed as available, yes | 15:57 |

ildikov | dulek: I was attending that meet up and answered multi attach questions | 16:10 |
*** alonma has quit IRC | 16:10 | |
dulek | ildikov: I guess it was fun. :) | 16:10 |
ildikov | dulek: we had a nostalgic, it is still needed moment with TWC guys... | 16:11 |
scottda | ildikov: We just discussed in-flight features for O release. Some (hemna ) thought multi-attach might not make it, whereas others (jgriffith ) thought it might. | 16:11 |
ildikov | I think it came up or was in the air to get priority for this thing in Nova | 16:12 |
hemna | if jgriffith thinks he can get it in, then cool | 16:12 |
dulek | I think we should just make sure we'll do everything to merge it in O. | 16:12 |
hemna | It seems like a lot for a 'stabilization' release | 16:12 |
*** alonma has joined #openstack-cinder | 16:13 | |
jgriffith | i don't know why multi-attach seems so hard. Once you fix the broken API's it should be pretty easy | 16:13 |
ildikov | So I think if we don't do anything with the new API plans in O, then it will never happen | 16:13 |
scottda | hemna: Agreed, but I think Sean's definition of stablization includes getting in-flight multi-release stuff done, and holding off on any new proposals | 16:13 |
ildikov | And if we have the new API multi attach is kind of there out of the box | 16:13 |
hemna | jgriffith, well, considering that I've tried 5 releases to get it working...... | 16:13 |
hemna | anyway, I'm all for it getting in. | 16:14 |
ildikov | It needs extensive testing, but the code part is not an issue, I mean no huge code change needed | 16:14 |

jgriffith | it's alright, I'll likely just sleep anyway. At least I get to go | 16:48 |
smcginnis | jgriffith: True | 16:48 |

erlon | jungleboyj: hmm, ok, I saw that | 16:49 |
*** porrua has joined #openstack-cinder | 16:49 | |
smcginnis | winston-d_: Oh no, that's a bummer. No chance it will work out yet? | 16:49 |
*** akapil has quit IRC | 16:49 | |
erlon | jungleboyj: but, the job gate runs in a ubuntu 14.04, that has libvirt 1.2.2 | 16:50 |
*** xyang has quit IRC | 16:50 | |
Swanson | The more packed the plane and the longer the flight the more likely I am to have to be subdued by the flight crew. Or mixing medication with alcohol. Which, so long as I keep breathing is probably the flight crew's preference. | 16:50 |
erlon | jungleboyj: I had passed sometimes with me too, but that does not make much sense | 16:50 |
winston-d_ | We have very tight budget control in Q4, I fought but didn't get approval. | 16:50 |
smcginnis | Swanson: I can't imagine you stuck on a plane for several hours. | 16:51 |

erlon | jungleboyj: there are 2 situations that happen when you delete a snapshot of an attached volume | 16:57 |
*** raunak has joined #openstack-cinder | 16:58 | |
jungleboyj | erlon: Right. I tried both of them by hand and they worked once the patch for NOva is applied. | 16:58 |
erlon | jungleboyj: 1 is you delete the first snapshot, and the other is when you delete the last snapshot | 16:58 |
jungleboyj | erlon: Yep. | 16:58 |
erlon | jungleboyj: using libvirt 1.2.2 | 16:59 |
jungleboyj | erlon: This was on libvirt 1.2.12 | 16:59 |
*** crose has quit IRC | 17:01 | |

winston-d_ | I got a './cinder/tests/unit/test_volume.py:422:9: F841 local variable 'vol2' is assigned to but never used' in my change, but this vol2 is actually useful and should stay in the change. How can I stop pep8 from complaining/ | 17:10 |
winston-d_ | put a '#noqa' right after the 'vol2' line? | 17:11 |
eharney | winston-d: i think that you can prefix it with "_" to say "i don't care that it's unused" | 17:11 |
eharney | winston-d: i.e. rename it to "_vol2" | 17:11 |
winston-d_ | eharney: ah, will try that. thx! | 17:13 |

eharney | winston-d: it didn't for me either, but, i'm about 99.9% sure i've used this before in Cinder | 17:23 |

*** cknight has joined #openstack-cinder | 18:50 | |
hemna | this is a different volume ? | 18:50 |
*** cknight1 has quit IRC | 18:50 | |
patrickeast | well | 18:50 |
patrickeast | its the same as far as cinder/nova is concerned | 18:50 |
*** fredli has quit IRC | 18:50 | |
patrickeast | but apparently mpathd and linux have something else to say about it | 18:50 |
hemna | wtf | 18:51 |
patrickeast | i know right | 18:51 |
hemna | how the hell is that happening? | 18:51 |
hemna | did we ask the right volume for the page 83 wwn ? | 18:51 |
patrickeast | hopefully i'll have more time this afternoon to dig in more | 18:51 |
hemna | multipath gets the wwn from page 83 | 18:52 |
patrickeast | i think so, lemmie check more of the log... | 18:52 |
patrickeast | yea | 18:52 |
* hemna wonders if there is a stale cached entry internally to the mpath devmap | 18:52 | |
patrickeast | i'm wondering if maybe some other dm-X device or dangling sdx device broke things | 18:52 |
patrickeast | haha yea | 18:52 |
*** Suyi_ has joined #openstack-cinder | 18:52 | |

openstackgerrit | Merged openstack/python-brick-cinderclient-ext: Add oslo.concurrency to requirements https://review.openstack.org/377247 | 18:57 |
patrickeast | the bf3a one | 18:57 |
hemna | uhh | 18:57 |
patrickeast | here one sec lemmie just start a tmate thing again, probably easier than live tweeting as i grep | 18:57 |
hemna | oh yah sorry | 18:57 |
hemna | ok | 18:57 |
patrickeast | so i just saw something interesting if i grep for the mapper id that it falls back to and tries to use | 18:58 |
patrickeast | that one was the mapper from the encrypted volume test | 18:58 |

patrickeast | hemna: nothing groundbreaking, keep getting pulled away for other things | 20:19 |
hemna | ok | 20:20 |
patrickeast | hemna: i did see some improvements by turning off the encrypted volume tests... they seem to trigger something bad with multipathd | 20:20 |
hemna | that's quite odd | 20:20 |
hemna | I'm really concerned about the scsi_id thing | 20:20 |
patrickeast | hemna: sorta, they are both using dev mapper devices | 20:21 |
patrickeast | yea | 20:21 |

openstackgerrit | Merged openstack/os-brick: s390x iscsi support enablement https://review.openstack.org/375415 | 20:21 |

patrickeast | dm* | 20:21 |
patrickeast | how/why is still a mystery | 20:22 |
*** alonma has joined #openstack-cinder | 20:22 | |
hemna | do you have the log of it finding the scsi_id and then looking for the /dev/mapper/<id> and then the fallback to calling multipath -l <device> | 20:22 |
patrickeast | yea somewhere | 20:24 |
* patrickeast digs around | 20:24 | |
hemna | ok | 20:24 |

patrickeast | its got teh scsi_id call | 20:30 |
patrickeast | and then it failing to find a device, falling back to a different dev/mapper | 20:30 |
hemna | ok I see it getting a wwn | 20:31 |
*** alonma has joined #openstack-cinder | 20:31 | |
patrickeast | there some debug output missing where it does multipath -l /dev/sdf and grabs that other id | 20:31 |
hemna | then going through it's attempt to find the mpath device | 20:31 |
hemna | which fails | 20:31 |
patrickeast | yea the paths aren't showing up | 20:32 |

hemna | the wwn is passed in | 20:34 |
*** alonma has quit IRC | 20:35 | |
hemna | https://github.com/openstack/os-brick/blob/master/os_brick/initiator/connectors/iscsi.py#L433 | 20:36 |
hemna | hmmm | 20:36 |
*** Apoorva has quit IRC | 20:36 | |
hemna | maybe there is a bug there | 20:36 |
patrickeast | hmm yea, could be | 20:37 |
*** akerr has quit IRC | 20:37 | |
hemna | so the first thing we do is rescan_iscsi | 20:37 |
patrickeast | doesn't make sense why it works on all the other os's though | 20:37 |
hemna | yah that part I dunno | 20:39 |
hemna | but we build the list of possible paths that might show up | 20:39 |
hemna | https://github.com/openstack/os-brick/blob/master/os_brick/initiator/connectors/iscsi.py#L543 | 20:39 |
hemna | basically there | 20:39 |
hemna | and the first path that we find in that list, we eject and say we found it. | 20:40 |
hemna | then we try and find a mpath device associated with that volume..... | 20:40 |
hemna | which is first via the scsi wwn of that discovered path. | 20:40 |
hemna | which fails | 20:40 |
hemna | and we fallback to multipath -d <realpath of the first path in the list> | 20:41 |
hemna | err multipath -l | 20:41 |
patrickeast | yea | 20:41 |
hemna | so.... | 20:42 |
hemna | I think host_devices contains all of the possible paths | 20:42 |
hemna | when we do the https://github.com/openstack/os-brick/blob/master/os_brick/initiator/connectors/iscsi.py#L433 call | 20:42 |
*** ccesario has quit IRC | 20:43 | |
hemna | which I believe will just give us the first one that passes the os.path.exists(dev) | 20:43 |
hemna | which theoretically could be an old volume with the same iqn lun combo | 20:43 |
patrickeast | hmm true | 20:44 |
hemna | but an incorrect wwn | 20:44 |
hemna | in the case of the race | 20:44 |
*** tpsilva has quit IRC | 20:44 | |
patrickeast | im adding in a bunch of a debug info we've been talking about, maybe i'll add in a dump of all the scsi ids | 20:44 |
patrickeast | check each one and log em | 20:44 |
mriedem | smcginnis: so! | 20:44 |
mriedem | smcginnis: summit sessions | 20:44 |
hemna | so for the 3PAR I can get the wwn from the array at the time I create the volume/export | 20:44 |
patrickeast | yea we can do that too | 20:45 |
mriedem | smcginnis: sdague suggested we do a nova/cinder multiattach session as a cross-project session in barcelona, | 20:45 |
*** jamielennox|away is now known as jamielennox | 20:45 | |
mriedem | so we don't eat up design summit slots | 20:45 |
patrickeast | i was thinking of adding it to be part of the initialize connection dict | 20:45 |
mriedem | smcginnis: what do you think? | 20:45 |
patrickeast | and in os-brick raise an error if it doesn't match | 20:45 |
hemna | patrickeast, ok yah dump out all of the host_devices and their scsi_id's prior to line 433 | 20:45 |
*** diablo_rojo has joined #openstack-cinder | 20:45 | |
hemna | patrickeast, yah that's kinda what I'm thinking | 20:45 |
hemna | we can validate the volume paths based on that. | 20:45 |
smcginnis | mriedem: That makes sense. | 20:45 |
patrickeast | hemna: definitely seems like the safe thing | 20:45 |
smcginnis | mriedem: Are there enough cross project slots available thought... | 20:46 |
hemna | yah I think so | 20:46 |
patrickeast | hemna: rather than some connection using a bad path | 20:46 |
smcginnis | *though | 20:46 |
hemna | that can be used for both FC and iSCSI | 20:46 |
patrickeast | yep, probably any volume attachment really | 20:46 |
patrickeast | well | 20:47 |
patrickeast | block volume attachment, none of the nfs business | 20:47 |
mriedem | smcginnis: yeah | 20:49 |

scottda | mriedem: smcginnis Should multi-attach session include or be encompassed by cinder-nova APi changes? The two are pretty tightly coupled. | 20:51 |
smcginnis | scottda: At least it would have to be after that discussion if they were separate, but I agree it should be part of the same conversation. | 20:52 |
mriedem | so, the cinder api rework is a pre-req for multiattach | 20:52 |
mriedem | so given the schedule it seems to make sense to do the xp session on the cinder api rework | 20:53 |
mriedem | and then another design summit session for follow up if needed | 20:53 |
mriedem | nova probably has more slots than we need so we could pencil that is | 20:53 |
mriedem | *in | 20:53 |
scottda | That sounds right. | 20:53 |
smcginnis | Okey dokey | 20:53 |
mriedem | sdague: i thought you said there were 18 xp slots? i only see 6 here https://etherpad.openstack.org/p/ocata-cross-project-sessions | 20:55 |
sdague | mriedem: 6 time blocks | 20:55 |
sdague | there can be 2 - 4 tracks at a time | 20:55 |
mriedem | ah | 20:55 |
sdague | unless that changed again | 20:55 |
mriedem | "Slots (6), we can use up to 4 parallel fishbowl rooms (but probably should not)" | 20:55 |
smcginnis | Ah, makes sense. | 20:55 |
sdague | we were running 3x in the last 3 summits | 20:56 |
smcginnis | That could quickly turn into a nightmare. | 20:56 |
mriedem | yeah i guess the point of the xp sessions is you want the actual projects to show up right? | 20:56 |
sdague | so I would assume that 18 is going to be the final number | 20:56 |
sdague | mriedem: some appropriate representation at least | 20:56 |
smcginnis | mriedem: We can always follow up on the work sessions, but half a day for that isn't going to give us a lot of time either. | 20:57 |
sdague | but a ton of people just skip, or are bored with meta conversations without concrete outcomes, so putting some more focussed things up for consideration would be a good call | 20:57 |
sdague | the worst thing that can happen is people say "no, you have to put it in your own track" | 20:57 |
sdague | but at this point people weren't proposing things largely because they were told not to in the past | 20:58 |
smcginnis | sdague: I think that has been our problem the last couple times as far as making progress. Hopefully we've gotten concrete enough to make progress now. | 20:58 |
*** chris_morrell has joined #openstack-cinder | 20:59 | |
sdague | also realize the work sessions are going to all be at the same time, like 34 running in parallel on the Friday afternoon from 2 - 6 (iirc) | 20:59 |
sdague | so... I would not anticipate that to be a great time to work on cross project issues | 20:59 |
smcginnis | yikes. Good point | 20:59 |
mriedem | nova won't get much done friday afternoon | 21:00 |
sdague | some substantial # of folks will have left, lots of people will be super burnt out | 21:00 |
mriedem | all of the red hat people from the eu are leaving | 21:00 |
smcginnis | OK, scratch that idea. We'll have to try to get as much done as we can in a xp session. | 21:00 |
patrickeast | hemna: ok, re-running to try and repro with all the extra logging | 21:06 |
hemna | ok | 21:06 |

ildikov | jgriffith: yeah, I'm repeating myself that a few times every day by now :) | 21:14 |

smcginnis | ildikov: We'll have to see where we end up. | 21:14 |

mriedem | ildikov: this is the proposed list | 21:14 |
mriedem | the TC decides next week | 21:14 |

patrickeast | i'm wondering how hard it would be to just stick it in os-brick instead of the cli calls | 22:27 |

hemna | I didn't run any of that as root | 22:33 |
patrickeast | oh man, thats soo good then | 22:33 |
patrickeast | new goal, eliminate needing privsep when attaching :p | 22:33 |
hemna | yah, bypass privsep | 22:33 |
hemna | so I may look at how much of what we have that I can rework | 22:34 |
patrickeast | sounds good | 22:35 |
patrickeast | i'm definitely interested in helping, so if theres a clean way to like split up some of this lemme know | 22:36 |

hemna | I'd really like to see if we can do something with adding bindings to libiscsi | 22:40 |
patrickeast | surely someone has already done it | 22:44 |
*** alonma has quit IRC | 22:44 | |
patrickeast | https://github.com/sahlberg/libiscsi-python | 22:44 |
hemna | yah, I tried that the other day | 22:45 |
hemna | I think it's too old for the current version of libiscsi | 22:45 |
patrickeast | oh is that the one that failed to install? | 22:45 |
hemna | lots of pukes trying to build it | 22:45 |
hemna | yah | 22:45 |
patrickeast | hrm, well thats maybe not too big of a blocker | 22:45 |
hemna | yah | 22:45 |
patrickeast | maybe fun weekend project | 22:45 |
hemna | the question I have is, if we use that for discovery and sessions, does that still create the udev devices ? | 22:45 |
*** ducttape_ has joined #openstack-cinder | 22:46 | |
patrickeast | mm | 22:46 |
patrickeast | i dunno | 22:46 |
patrickeast | i only have a vague idea of how the event stuff happens to trigger udev doing its thing | 22:46 |
hemna | but there are cinder drivers that use iscsiadm to discover iqns | 22:46 |
patrickeast | not sure if we have to poke it, or if there are hooks in the kernel for it | 22:46 |
hemna | we could bypass all of that, if we had python bindings to libiscsi | 22:46 |
patrickeast | yep | 22:46 |
patrickeast | would be good stuff | 22:46 |
hemna | yah I think so | 22:47 |
patrickeast | we could probably do neat things like detecting error states and doing smarter things there too | 22:47 |
hemna | it might be worth spending some time just to get a limited binding set to work | 22:47 |

*** salv-orlando has joined #openstack-cinder | 22:48 | |
hemna | patrickeast, looks like that libiscsi-python was generated by SWIG | 22:49 |
* hemna wonders if we can re-generate it | 22:49 | |
patrickeast | probably | 22:49 |
* hemna is unfamiliar with SWIG | 22:49 | |
patrickeast | all i know is folks complaining about it the other day | 22:49 |
hemna | oh ? | 22:50 |
hemna | (apt install swig) | 22:50 |
patrickeast | i forget, was it jgriffith? smcginnis? ^^ | 22:50 |
patrickeast | someone mentioned using it before | 22:50 |

*** salv-orlando has quit IRC | 22:52 | |
hemna | damn | 22:53 |
hemna | so yah, I think libiscsi.i is the magic sauce | 22:53 |
hemna | that swig consumes to generate the .py and .c bindings | 22:53 |
smcginnis | patrickeast: Yeah, jgriffith warned us away from it. :) | 22:53 |

hemna | ah yah | 23:08 |
hemna | there is an issue of the API being out of date | 23:08 |
hemna | looking at the headers | 23:08 |
hemna | bah | 23:08 |
