| 22:22:50 | sean-k-mooney | ah https://wiki.openstack.org/wiki/Glance-v2-community-image-visibility-design#Visibility_Semantics | |
| 22:23:18 | gmann | melwitt: i am trying to test the stable gate(stein) with the fix on legacy base job, let's see if that fix the things - https://review.opendev.org/#/c/737332/3 | |
| 22:24:44 | gmann | problem is that, neither devstack nor devstack-gate install virtualenv on subnode | |
| 22:24:56 | sean-k-mooney | gmann: that was recently changed | |
| 22:25:48 | gmann | since last week it is failing, devstack stable branch and neutron-grenade jobs are fixed but we have nova multinode jobs legacy one | |
| 22:25:51 | sean-k-mooney | http://lists.openstack.org/pipermail/openstack-discuss/2020-June/015204.html | |
| 22:26:07 | gmann | sean-k-mooney: yeah, image update | |
| 22:26:59 | sean-k-mooney | didnt infra plan to fix all jobs | |
| 22:27:13 | sean-k-mooney | they had planned to propose patches to the base jobs | |
| 22:27:27 | gmann | :), no. legacy jobs are always less priority to fix. | |
| 22:27:58 | melwitt | gmann: cool thanks, I'll keep an eye on it | |
| 22:27:59 | gmann | zuulv3 native are easy to fix and add those roles wherever needed. like ensure-tox etc | |
| 22:33:51 | gmann | sean-k-mooney: and it depends on failure too, like 'tox not found' failure due to image updates needs to be fixed on wherever needed not in base job - #3 in this http://lists.openstack.org/pipermail/openstack-discuss/2020-June/015559.html | |
| 22:34:10 | gmann | tox issue also started happening in neutron, horizon, and few more repo | |
| 22:34:39 | gmann | so we discussed not to fix in devstack base job instead on failure side. | |
| 22:35:33 | sean-k-mooney | ya the whitebox-tempest-plugin job also broke but we fixed it | |
| 22:35:53 | sean-k-mooney | that is zuulv3 so we just added ensure-pip | |
| 22:36:02 | gmann | putting everything in base job can overload the jobs who does not need these tools. | |
| 22:36:49 | sean-k-mooney | gmann: our issue with whitebox was our pre playboox uses pip before devstack runs and installs pip | |
| 22:37:11 | gmann | ok | |
| 22:37:11 | sean-k-mooney | so we just added ensure-pip | |
| 22:37:14 | sean-k-mooney | easy fix | |
| 22:39:55 | gmann | for xenial node ensure-vitualenv does ensure-pip also but for bionic yes we need to it in start - https://opendev.org/zuul/zuul-jobs/src/branch/master/roles/ensure-virtualenv/tasks/Debian.yaml#L9 | |

| 08:31:54 | jcath | hello,friends, how I can attach a volume to an exist instance as an ide disk/cdrom? whatever you set hw_disk_bus/hw_cdrom_bus in the image metadata, it does not work | |
| 09:34:11 | openstackgerrit | Hervé Beraud proposed openstack/nova master: Remove elementtree deprecated methods https://review.opendev.org/737472 | |
| 10:48:14 | nightmare_unreal | a quick question can a cell have multiple compute nodes ? | |
| 11:06:44 | gibi | nightmare_unreal: yes a cell is a set of computes that has its own cell conductor, a cell db, and a cell message bus | |
| 11:07:59 | nightmare_unreal | thanks gibi , I forgot some stuff/terms | |
| 11:18:48 | gibi | stephenfin: I have a question in https://review.opendev.org/#/c/737026/ | |
| 11:22:18 | stephenfin | gibi: I'll trade https://review.opendev.org/#/c/736964/6 | |
| 11:23:04 | gibi | stephenfin: thanks | |
| 11:30:18 | openstackgerrit | Hervé Beraud proposed openstack/nova master: Remove lxml deprecated methods https://review.opendev.org/737472 | |
| 11:47:37 | nightmare_unreal | how can i get list of all compute nodes in a cell ? | |
| 11:59:32 | gibi | nightmare_unreal: nova-manage cell_v2 list_hosts | |
| 12:01:01 | nightmare_unreal | Yeah found it . I am now looking to do it programatically is nova-manage part of python-novaclient ? | |
| 12:08:51 | gibi | nightmare_unreal: no. the cell is a deployment level thing, it is not exposed via the REST API | |
| 12:09:35 | nightmare_unreal | Ah, okay !! | |

| 12:25:25 | gibi | stephenfin: responeded in https://review.opendev.org/#/c/736964 I don't get your comment about st_blocks | |
| 13:01:57 | stephenfin | gibi: Ah, ignore me: momentary lapse | |
| 13:07:51 | gibi | stephenfin: no worries. Thanks for reviewing | |
| 14:07:41 | aarents | dansmith: Let me know if those changes are ok: https://review.opendev.org/#/c/736169/ https://review.opendev.org/#/c/734776/ | |
| 14:14:53 | openstackgerrit | Dan Smith proposed openstack/nova master: DNM: Try to make a glance multistore job https://review.opendev.org/734184 | |
| 14:25:56 | dansmith | aarents: looks like it from a high level.. will try to get back to those today if I can | |
| 14:27:19 | aarents | dansmith: thks | |
| 14:35:14 | sean-k-mooney | dansmith: so based on https://review.opendev.org/#/c/737548/ | |
| 14:35:30 | sean-k-mooney | dansmith: are we only going to then copy the image if we own it | |
| 14:35:45 | sean-k-mooney | or do you intned to have nova fall back to admin credetials | |
| 14:35:56 | dansmith | we're only going to be allowed to copy it if we own it at the moment, and we should not copy it with admin credentials | |
| 14:36:03 | dansmith | so basically, much less useful | |
| 14:36:16 | sean-k-mooney | ya that is what i was worreid about | |
| 14:36:26 | sean-k-mooney | but it also makes sense | |
| 14:36:32 | dansmith | the argument is that the owner of the image, despite being viewable, is "charged" to the owner for each location | |
| 14:36:39 | dansmith | although there isn't a resource usage report to convey this | |
| 14:36:49 | sean-k-mooney | yep | |
| 14:36:54 | dansmith | it seems to me that if an image is made public, charging the owner for it doesn't make much sense, | |
| 14:37:01 | sean-k-mooney | that is what i was wondering yesterday re billing | |
| 14:37:21 | sean-k-mooney | dansmith: the image can only be public if you are an admi | |
| 14:37:33 | dansmith | I think this is a very leaky concept unfortunately | |
| 14:37:37 | sean-k-mooney | communtiy images are also more or less public | |
| 14:37:51 | sean-k-mooney | those can be uploaded by non admins | |
| 14:38:06 | sean-k-mooney | but are not in the defualt image list i think | |
| 14:38:15 | dansmith | so my example is that you own an image, you push it to a site, get charged for it being there, I boot an instance from it, you delete it from that store, but my instance is still backed, so I'm still consuming the space, although glance can't reflect that, so I get it for free | |
| 14:38:45 | dansmith | it doesn't matter, if I can see an image I don't own, and can boot instances from it, then I can consume resources you're charged for | |
| 14:39:20 | sean-k-mooney | ya so that model does nto really work though | |
| 14:39:33 | sean-k-mooney | are you still chared for the glance image after its deleted | |
| 14:39:43 | sean-k-mooney | if you have vms that were booted form it? | |
| 14:39:54 | sean-k-mooney | that seams like double billing | |
| 14:40:00 | dansmith | the question is whether *other* users have instances | |
| 14:40:10 | sean-k-mooney | well even if the dont | |
| 14:40:17 | dansmith | I would hope that if you try to remove an image from a store, you fail if there are instances booted from it | |
| 14:40:18 | sean-k-mooney | if you upload an iamge boot a vm and delete the image | |
| 14:40:26 | sean-k-mooney | you should not be changed for the iamge storage right | |
| 14:40:44 | dansmith | which means if I push an image to an edge site and am charged for it, and someone *else* boots an image to pin it there, I can't delete it and stop being billed until this other user I don't know stops using it | |
| 14:41:00 | sean-k-mooney | dansmith: removing a image in genrall we would not block removing an image form the store maybe | |
| 14:41:23 | dansmith | in that case, we leak it and either have no way to delete it later, or have no way to charge it to anyone | |
| 14:41:32 | sean-k-mooney | the glance store concept is also problemeatinc in this regrad | |
| 14:41:34 | dansmith | it's broken in one of three ways I think | |
| 14:42:10 | sean-k-mooney | well for the file backend once i boot a vm form it i dont need the glance copy right | |
| 14:42:25 | sean-k-mooney | for the rbd backedn or cinder backend then that is different | |
| 14:42:38 | dansmith | yeah, I'm talking about rbd or any other managed shared backend type | |
| 14:42:40 | sean-k-mooney | because we are doing a shallow snapshot fo the new volume | |
| 14:43:02 | dansmith | but the copy-to-store functionality was added for this rbd edge case specifically | |
| 14:43:19 | sean-k-mooney | but i dont think i should be change for that backing volume since im paying for the space via the vm | |
| 14:43:51 | sean-k-mooney | and in the case where you use my iamge you are paying for the space with your image | |
| 14:43:52 | dansmith | that's another good point, I'm not sure how that works either.. | |
| 14:44:00 | sean-k-mooney | because without this we would have flatened it | |
| 14:44:15 | dansmith | basically, I thought image billing was done by just listing the images and counting up the image_size attributes, which would not include the multiple copies | |
| 14:44:25 | dansmith | which I understand might not be right, in terms of actual bytes used | |
| 14:44:42 | sean-k-mooney | dansmith: that i assuemd would be the case too | |
| 14:45:05 | sean-k-mooney | multi sotre potentally changes that | |
| 14:45:12 | dansmith | yeah | |
| 14:45:16 | sean-k-mooney | but i dont think it should nessisarly | |
| 14:45:43 | sean-k-mooney | is this something we would want to expose to an operator via a nova config option | |
