| 21:01:54 | admin1 | i will try to find more | |
| 21:02:07 | admin1 | melwitt, in absense of this setting, how does the nova snapshot work ? | |
| 21:02:08 | melwitt | another thing that can cause it to not do the CoW is if the image is not in RAW format, but I think glance might automatically convert to RAW now, depending on what release you have | |
| 21:02:19 | admin1 | all images are in raw format | |
| 21:02:31 | admin1 | i converted them before uploading to glance | |
| 21:02:58 | melwitt | that is a warning that the backend url will be shown to users querying glance API so it should not be a url that is publicly accessible (for security reason) | |
| 21:03:45 | melwitt | ok cool. if you don't set up as described in that ceph doc, nova will download the image from glance first and then boot the instance | |
| 21:04:40 | melwitt | if the image is large, it can be slow | |
| 21:08:37 | melwitt | there's some glance setting around chunk size which you might want to adjust to get better throughput, I think it's this? https://docs.openstack.org/glance/latest/configuration/glance_api.html#glance.store.rbd.store.rbd_store_chunk_size | |

| 21:18:58 | opendevreview | melanie witt proposed openstack/nova master: Add section for 'nova-manage placement audit' tool https://review.opendev.org/c/openstack/nova/+/809479 | |
| 21:26:55 | admin1 | melwitt, when you meant backend url, is that the url of the ceph ? | |
| 21:27:01 | admin1 | i mean its osd url | |
| 21:29:12 | admin1 | melwitt, what glance command can i use to see the url being exposed .. | |
| 22:07:48 | opendevreview | melanie witt proposed openstack/nova master: Add section for 'nova-manage placement audit' tool https://review.opendev.org/c/openstack/nova/+/809479 | |
| 22:19:47 | melwitt | admin1: yeah ceph url I think. you can see it by doing an 'image show' if you have enabled showing it https://docs.openstack.org/api-ref/image/v2/index.html?expanded=show-image-detail#show-image | |
| 22:20:13 | melwitt | https://docs.openstack.org/python-openstackclient/latest/cli/command-objects/image-v2.html#image-show | |
| 22:45:33 | dansmith | admin1: that location thing means glance will show things like rbd://mycephserver:port/path/to/thing, and so you likely want a different endpoint with that enabled that regular untrusted users can't see | |
| 22:46:00 | dansmith | admin1: without the fast cow snapshot, nova will pause the VM, download its disk, flatten it out, upload it to glance, and then unpause the VM | |
| 22:46:30 | dansmith | admin1: it's far more efficient to just let ceph snapshot it for you (pretty much instantaneously) and then just tell glance it exists | |

| 07:26:11 | bauzas | gibi: thanks for having approved the nova RC1 change | |
| 07:26:38 | gibi | bauzas: the gate seems to be down due to pip resolve issue (jobs times out) so we haven't merged the RC1 yet | |
| 07:26:46 | bauzas | yeah I saw | |
| 07:26:54 | bauzas | infra is on it ? | |
| 07:27:12 | gibi | release team knows it but nobody able to reproduce it locally afaik | |
| 07:27:17 | bauzas | shit. | |
| 07:53:59 | bauzas | gibi: I'm happy to see you signed up our team for the PTG :p | |
| 07:54:39 | gibi | bauzas: yepp I did that early :) | |
| 07:54:46 | gibi | would be fun missing that | |
| 07:55:04 | bauzas | what could be fun would be the miss the registration | |
| 07:55:10 | bauzas | be to miss* | |
| 07:59:50 | songwenping_ | bauzas: morning, i have two gpus virtualized on my env, and i config one pci address for the vgpu device_addresses, but nova report all gpus to placement, is this a bug? | |
| 08:00:14 | bauzas | songwenping_: could you provide me the conf ? | |
| 08:00:24 | bauzas | songwenping_: I think it's because you only have one type | |
| 08:00:36 | bauzas | you need to create a fake second type | |
| 08:00:37 | songwenping_ | yes, only one type. | |
| 08:00:43 | bauzas | yeah, I know, it's bad | |
| 08:01:05 | bauzas | do something like enabled_vgpu_types = nvidia-XXX, foo | |
| 08:01:17 | bauzas | and create a fake section [vgpu_foo] | |
| 08:01:20 | bauzas | with a fake device | |
| 08:01:41 | bauzas | that's because we don't look at the vgpu sections if we only have one type | |
| 08:01:55 | bauzas | for supporting the previous releases | |
| 08:02:14 | songwenping_ | yes, i looked into the code. | |
| 08:02:38 | songwenping_ | if the lenth of supported type is 1, it returns the type. | |
| 08:04:27 | bauzas | yup | |
| 08:05:54 | songwenping_ | will we change this logic? | |
| 08:10:37 | bauzas | songwenping_: we could remove the compatibility and just look whether we have a specific section | |
| 08:11:06 | bauzas | actually, this would continue to support the compatibility | |
| 08:11:33 | bauzas | songwenping_: if you want, create a new bug report and if you want, you could provide a new change that I'd review | |
| 08:11:45 | bauzas | it's simple, that's only done in a methond | |
| 08:11:47 | bauzas | method* | |
| 08:12:52 | songwenping_ | bauzas: ok, i will report a new bug and fix it. | |
| 08:13:04 | bauzas | songwenping_: lovely, thanks ! | |
| 08:13:29 | songwenping_ | cool | |
| 08:39:31 | gibi | melwitt, bauzas: the placement release notes now published properly https://docs.openstack.org/releasenotes/placement/xena.html | |
| 08:39:41 | bauzas | naïce | |
| 08:39:50 | gibi | you have strange letters :) | |
| 08:40:40 | bauzas | ... tells someone speaking Hungarian :p | |
| 08:40:53 | gibi | those are not strange :D | |
| 08:40:56 | gibi | to me :D | |
| 08:41:16 | gibi | áÁ-éÉ-íÍ-óÓ-öÖ-őŐ-úÚ-üÜ-űŰ | |
| 08:41:43 | bauzas | heh | |
| 08:41:59 | bauzas | actually, naïce is a French pun | |
| 08:42:23 | bauzas | this is because naice would mean "ai" == "è" (like heh) | |
| 08:42:43 | bauzas | instead, aï mean "ah-ee" | |
| 08:43:30 | bauzas | and of course, you know the "ain" which is only one syllab | |
| 08:44:09 | gibi | playing with phonetic | |
| 08:44:12 | gibi | that is fun | |
| 08:44:46 | gibi | hungary has some strange phonetic compared to the english e.g. around s, z, sz, zs, | |
| 08:46:04 | gibi | basically how s sounds in english is sz in hungarian | |
| 08:46:24 | gibi | and the hungarian s is closer to sh in english | |
| 08:47:35 | opendevreview | Wenping Song proposed openstack/nova master: Remove the code that never reach https://review.opendev.org/c/openstack/nova/+/809572 | |
| 08:50:42 | bauzas | gibi: I know, Balach :p | |
| 08:51:12 | bauzas | or should I say Balass actually ? | |
| 08:51:26 | gibi | I don't know a direct mapping betwen zs sound to english | |
| 08:51:45 | bauzas | I remember you telling me once "Balach" but I could be wrong | |
| 08:51:50 | gibi | ohh | |
| 08:51:52 | gibi | google helped | |
| 08:51:53 | gibi | zs (pronounced like the “s” in pleasure) | |
| 08:52:19 | bauzas | I see | |
| 08:52:42 | gibi | plezsör | |
| 08:52:52 | bauzas | lol | |
| 08:52:53 | gibi | if I use hungarian pronunciation :D | |
| 08:53:05 | bauzas | plizure | |
| 08:53:32 | bauzas | actually, plizeure | |
| 09:00:03 | gibi | and our languages are not even that far from each other, I guess gmann could add many other strangness to this discussion | |
| 09:00:15 | gibi | or alex_zu | |
| 09:01:13 | bauzas | heh | |
| 09:01:22 | bauzas | on a sad note, RC1 is still on the weeds https://review.opendev.org/c/openstack/releases/+/808706 | |
| 09:01:33 | bauzas | I'm tempted to recheck but i'm not sure it will help | |
| 09:03:09 | gibi | elodilles and hberaud discussion the issue on #openstack-release | |
| 09:03:13 | gibi | so I opt to wait a bit | |
| 09:05:28 | bauzas | oh, was looking at the release chan ealier | |
| 09:13:01 | gibi | and elod is actally előd where ő is the double long sound of 'e' in the english her | |
| 09:13:17 | gibi | elodilles: // | |
| 09:13:41 | gibi | I mean ^^ | |
| 09:13:58 | gibi | just I had to switch layout for ő | |
| 09:15:32 | elodilles | :) | |
