| 12:33:52 | sean-k-mooney | by the way there si not ceph level rbd caching as well | |
| 12:34:00 | sean-k-mooney | i.e. at the ceph.conf level | |
| 12:36:22 | sean-k-mooney | i think the current recommendaions are to weriteback at the qemu level and enabling rbd cachign with ` rbd cache writethrough until flush = true` at the rbd/ceph level | |
| 12:36:54 | sean-k-mooney | with that sadi the removed the expiclty specificatgion of the livbirt cache_mode form there doc at some poitn | |
| 12:37:39 | sean-k-mooney | https://docs.ceph.com/en/mimic/rbd/rbd-openstack/#id2 | |
| 12:38:25 | sean-k-mooney | gokhan: one of hte main reasonis for usein virtio-scsi in the past was for discard/trim supprot because that was not previously implmented wehn useing virtio-blk | |
| 12:38:58 | sean-k-mooney | that gap has been resolved in the last 2-3 years in modern qemu releases | |
| 12:41:25 | gokhan | sean-k-mooney, there is no cache on ceph environment | |
| 12:41:40 | gokhan | ı will try with new configs | |
| 12:41:51 | sean-k-mooney | rbd cachign is apprenly enabled by default reading the ceph docs | |
| 12:52:03 | gokhan | sean-k-mooney, do we need to disable it or keep as is | |
| 12:53:25 | sean-k-mooney | honestly this is not something we test or can really advise on. you might get more userful feedback form the ops mailing list or operator hour session | |
| 12:53:54 | sean-k-mooney | the best i can do is point you at the offical docs from teh ceph comnuity above | |
| 12:54:43 | sean-k-mooney | well that and https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L668-L700 | |
| 12:55:10 | sean-k-mooney | a flush form the guest is flushed to ceph in all cases expct unsafe | |
| 12:55:53 | sean-k-mooney | you absolutely shoudl no use unsafe unless you hate your guests data | |
| 12:57:15 | sean-k-mooney | i woudl read that comemtn that explians the differnt modes in detail and decive which fits your performance and correctness needs | |
| 12:57:44 | sean-k-mooney | a guest shoudl never rely on writs being commited without flushing. if they do they have a bug in there software | |
| 12:58:29 | sean-k-mooney | writethough and directsync will inject extra fsync on every wite with the performance penaly that implies | |
| 13:07:23 | gokhan | disk_cachemodes=file=none,block=none,network=none | |
| 13:07:24 | gokhan | is also not worked forthis scenario. Now I am trying with recommended settings | |
| 13:13:19 | gokhan | sean-k-mooney, I find the problem. ceph is locked disk from previous host. | |
| 13:16:02 | gokhan | rbd lock list cinder-volumes/volume-4263698a-ad00-472c-b4c8-62591664a8e1 | |
| 13:16:02 | gokhan | There is 1 exclusive lock on this image. | |
| 13:16:02 | gokhan | Locker ID Address | |
| 13:16:02 | gokhan | client.95989750 auto 125705438402288 10.x.x.x:0/1193021369 | |
| 13:18:20 | gokhan | sean-k-mooney, I also saw tour response to mail list https://lists.openstack.org/pipermail/openstack-discuss/2023-February/032256.html | |

| 15:54:18 | tkajinam | hmmm so there is an issue with zuul now and jobs may be delayed for some time. | |
| 15:54:45 | tkajinam | I mean it take some time until zuul actually starts processing notifications from gerrit | |
| 15:55:02 | tkajinam | (seeing the discussion in OpenDev room in matrix | |

| 16:00:55 | Uggla | Hello everyone | |
| 16:01:15 | elodilles | o/ | |
| 16:01:21 | bauzas | o/ | |
| 16:01:31 | kaisers | o/ | |
| 16:01:31 | sean-k-mooney | o/ is here but distracted | |

| 16:01:47 | gmaan | o/ | |
| 16:02:08 | lajoskatona | o/ | |
| 16:03:04 | Uggla | Let's start | |

| 16:03:15 | fwiesel | o/ | |
| 16:03:23 | Uggla | #info No Critical bug | |
| 16:03:27 | tkajinam | https://bugs.launchpad.net/nova/+bug/2143057 | |
| 16:03:39 | Uggla | oh | |
| 16:03:45 | dansmith | o/ | |
| 16:03:47 | tkajinam | there is one I reported 1 hour ago (I changed its importance a few minutes ago) | |
| 16:03:56 | tkajinam | which is blocking the novaclient CI | |
| 16:04:33 | tkajinam | I've proposed a potential fix but zuul is now slow and is not starting jobs timely... | |
| 16:04:56 | Uggla | ok I have seen you message earlier about this. | |
| 16:05:00 | tkajinam | yeah | |
| 16:05:36 | Uggla | the bug sounds like something introduced with openapi. | |
| 16:05:55 | Uggla | am I right ? | |
| 16:06:06 | tkajinam | yup | |
| 16:06:15 | tkajinam | the error is caused by schema validation of responses | |
| 16:06:23 | sean-k-mooney | well that or its now showign a bug in the client | |
| 16:06:27 | tkajinam | which was recently enabled at the last phase of openapi series | |
| 16:06:41 | sean-k-mooney | ya so respocne validation is only enabeld in ci | |
| 16:06:47 | gmaan | is not the test should be fixed in novaclient? | |
| 16:06:49 | sean-k-mooney | it not inteneded for production use | |
| 16:07:04 | sean-k-mooney | and ya i am wonderign if its a novaclinet issue or not | |
| 16:07:12 | gmaan | if API doc says, default is the only supported | |
| 16:07:26 | tkajinam | but only API doc says that. that is the problem. | |
| 16:07:33 | gmaan | fake-class-2-1 -> 'default' | |
| 16:07:45 | tkajinam | I mean API doc says only default is supported but it's not actually validated in API | |
| 16:07:53 | sean-k-mooney | tkajinam: that is the actual api contract however | |
| 16:08:43 | tkajinam | I'm ok with "fixing" novaclient tests but in that case we should also fix nova to return an appropriate error to client for non-default id | |
| 16:08:53 | tkajinam | currently it returns 400 with response schema validation error | |
| 16:09:10 | sean-k-mooney | im alittel confused because i see tempst/lib/cli in that path | |
| 16:09:26 | sean-k-mooney | are these novaclient tempest tests? | |
| 16:09:38 | sean-k-mooney | "/home/zuul/src/opendev.org/openstack/python-novaclient/.tox/functional/lib/python3.12/site-packages/tempest/lib/cli/base.py" | |
| 16:10:15 | gmaan | novaclient but they use tempest base test for cli | |
| 16:10:23 | sean-k-mooney | ack | |
| 16:10:24 | gmaan | anyways, let's continue on gerrit, I wll comment there | |
| 16:10:34 | tkajinam | ok | |
| 16:10:49 | Uggla | good thx gmaan | |
