| abhishekk | jokke, rosmaita, smcginnis, dansmith, weekly meeting @ #openstack-meeting in 2 minutes | 13:58 |
| rosmaita | ty | 13:58 |
| dansmith | I just missed the end, | 14:26 |
| dansmith | but I would love to know who uses it so I can ask them questions | 14:26 |
| dansmith | but without it being public, that was pretty hard | 14:26 |
| dansmith | since the biggest part of the advisory (IMHO) was ignored and just publicized with no handling recently, I think it was pretty much out of our hands anyway | 14:28 |
| abhishekk | https://etherpad.opendev.org/p/glance-xena-ptg-metadefs rosmaita is drafting something, if you want to add | 14:28 |
| abhishekk | yeah one of the bug which was reported in 2015 made public around Feb last week | 14:29 |
| dansmith | I think it was 2016, but yeah..sat for half a decade :) | 14:30 |
| abhishekk | right, sorry :D | 14:31 |
| abhishekk | its public holiday for me today | 14:31 |
| abhishekk | so planning to drop early | 14:31 |
| rosmaita | abhishekk: have a good holiday? | 14:32 |
| abhishekk | please send me mail if anything is required | 14:32 |
| abhishekk | rosmaita, thank you? :D | 14:32 |
| rosmaita | quick question about https://etherpad.opendev.org/p/glance-xena-ptg-metadefs ... do we want to discuss at the ptg, or set up a private videoconf? | 14:32 |
| dansmith | haha | 14:32 |
| abhishekk | as it is public we can discuss at PTG | 14:33 |
| abhishekk | dropping now, o/~ | 14:33 |
| dansmith | PTG seems good to me | 14:33 |
| rosmaita | ok, cool | 14:34 |
| dansmith | rosmaita: on the "turn off create to limit DoS" thing.. it's not clear to me how this is really supposed to work, | 14:35 |
| dansmith | because I would think that would make them *rely* on the non-isolation to use definitions by someone else, which they're not supposed to be able to see but can actually? | 14:35 |
| dansmith | obviously it seems not worth our time to try to figure it out without some users, especially right now | 14:36 |
| rosmaita | well, that's a different issue | 14:36 |
| rosmaita | the way i see it, is most people don't actually use metadefs, but the feature is there in every deployment, and now everyone knows you can DOS glance | 14:37 |
| dansmith | well, that was out of our hands a while ago | 14:38 |
| dansmith | a year ago: https://bugs.launchpad.net/glance/+bug/1545702 | 14:38 |
| openstack | Launchpad bug 1545702 in Glance "[OSSN-0088] Images v2 api metadef vulnerability" [Undecided,Confirmed] | 14:38 |
| dansmith | so the OSSN made sure that the operators know they should likely disable it, instead of just people hunting through the bug tracker looking for unaddressed vulnerabilities :) | 14:39 |
| rosmaita | dansmith: just add that paragraph, abhishekk can remove it later if he doesn't like it | 14:41 |
| dansmith | rosmaita: the one I'm typing into the etherpad? | 14:42 |
| rosmaita | yeah | 14:42 |
| dansmith | ack | 14:42 |

| admin0 | hi all .. does anyone have any pointers to this bug? https://bugs.launchpad.net/glance/+bug/1916482 | 18:24 |
| openstack | Launchpad bug 1916482 in Glance "rbd.IncompleteWriteError: RBD incomplete write (Wrote only 8388608 out of 8394566 bytes) since Victoria Upgrade, ceph v nautilus" [Undecided,New] | 18:24 |

| *** ralonsoh has quit IRC | 18:48 | |
| *** k_mouza has quit IRC | 18:53 | |
| dansmith | admin0: I don't really, but the logs make it look like the rbd image disappeared during the write | 18:53 |
| dansmith | like something external deleted it | 18:53 |
| *** jawad_axd has quit IRC | 19:18 | |
| *** belmoreira has quit IRC | 19:31 | |

| admin0 | dansmith, rbd.IncompleteWriteError: RBD incomplete write .. is that from ceph side or glance side ? | 19:32 |
| dansmith | this is what I was focused on: Snap Operating Exception [errno 2] RBD image not found | 19:33 |
| dansmith | which I assume means the glance rbd driver got a notfound from ceph | 19:33 |
| dansmith | I think the "incomplete write" probably comes from the rbd client library | 19:34 |
| admin0 | Since image size is zero we will be doing resize-before-write which will be slower than normal -- what does thsi line mean ? | 19:36 |
| admin0 | is this something significant ? | 19:36 |
| dansmith | it's expected, | 19:36 |
| dansmith | that means we're not doing sparse writes to rbd, because we don't know the image size ahead of time | 19:36 |
| dansmith | reading that now, it's probably the wrong thing to say.. I think it really means "as slow as pre-victoria" which is quite different :) | 19:37 |
| dansmith | ah, no, | 19:41 |
| dansmith | it existed before victoria, but the wording changed a bit | 19:41 |
| dansmith | but the behavior was the same before, which was my point | 19:41 |
| dansmith | with no image size ahead of time, the rbd code resizes the image every time it writes a chunk | 19:41 |
| dansmith | so, create rbd image 1MB, write 1MB, extend by 1MB, add another 1MB, over and over until EOF | 19:42 |
| dansmith | the resizing along the way is the "slower than normal" reference | 19:42 |
| dansmith | and 1MB is just my placeholder for whatever the block size is | 19:42 |
| dansmith | admin0: confirmed "incomplete write" doesn't exist in glance_store, so I'm sure that comes from the rbd client libs | 19:44 |
| *** rcernin has joined #openstack-glance | 20:00 | |
| admin0 | dansmith, it could be a packer issue .. so opened a bug report here: https://github.com/hashicorp/packer/issues/10753 | 20:16 |

| admin0 | dansmith, many thanks | 21:36 |
| admin0 | dansmith, i heard with a ceph backend, taking glance snapshot is not optimal .. is that true ? | 21:36 |
| admin0 | not optimal . error prone .. somethign like that | 21:37 |

| dansmith | admin0: snapshot from nova? | 22:03 |
| dansmith | it should be much better than any other snapshot option | 22:03 |
| dansmith | if properly configured, nova just asks ceph to take the snapshot, tells glance about it, and you continue running | 22:03 |
| dansmith | way faster, less data moving around | 22:04 |
| admin0 | ok | 22:04 |
