| 11:55:57 | elodilles | sean-k-mooney: about novaclient release model change you raised during friday evening: yeah, so a patch should be created in openstack/releases repository where we move the novaclient from the deliverables/hibiscus -> deliverables/_independent (note that python-novaclient was release for gazpacho already) | |
| 11:56:43 | elodilles | sean-k-mooney: and we can do this after 2026.1 Gazpacho release, after we have created deliverables/hibiscus o:) | |
| 11:57:22 | elodilles | sean-k-mooney: i forgot about this one after the Antelope PTG :/ | |
| 12:00:11 | elodilles | sean-k-mooney: one comment though: once we have moved python-novaclient to 'independent' we won't be able to do stable releases. in general this would not be a problem. BUT.... if there is any important bug fix and the master branch is dropped old py3 version (or other similar) support then we won't be able to get that fixed on stable branches. so this is something to be keep in mind if we want | |
| 12:00:17 | elodilles | to move a deliverable to cycle independent model | |
| 12:02:07 | elodilles | sean-k-mooney: i'm saying this as we had in the past some issues when multiple oslo project moved to independent model and caused issues when fixes could not be added and released. so oslo projects moved back from cycle independent to cycle based release model because of this. | |
| 12:03:06 | sean-k-mooney | elodilles: so whe ahve dicussed entirly frezing novaclient and discontiuing even bug fix release | |
| 12:03:38 | sean-k-mooney | the only reaosn it still exist is to provide a brindge for serivice like heat or neutron to move to the sdk | |
| 12:03:53 | sean-k-mooney | it might make snes for use to jsut go do that for those services next release | |
| 12:04:21 | sean-k-mooney | the same way neuton is moving nova to the sdk this cycle | |
| 12:05:29 | elodilles | sean-k-mooney: can we set novaclient as retired maybe next cycle? | |
| 12:05:49 | sean-k-mooney | i was thinking more for 2027.1 | |
| 12:05:50 | elodilles | maybe that would be the most straightforward way | |
| 12:06:36 | elodilles | sean-k-mooney: i see, 2027.1 also sounds OK to me | |
| 12:06:49 | sean-k-mooney | we still have services using it so if we set that as a goal for 2027.1 that give 2 relases to complete the move but we shoudl discuss that with the wider team | |
| 12:07:01 | sean-k-mooney | watcher had it as a priorty this cycle | |
| 12:07:31 | elodilles | sean-k-mooney: this cycle the clients are already released, so i think we cannot do anything about it | |
| 12:07:42 | sean-k-mooney | ya we cant | |
| 12:07:50 | sean-k-mooney | which is fine | |
| 12:08:15 | elodilles | ACK | |
| 12:09:49 | sean-k-mooney | i actully need to add "supprotign watcher in the sdk" to the ptg adjenda there and speak to stephen et al about the right way to do that so whtat we can also deprecate adn or remove the watcherclient python binding in a similar time frame | |
| 12:21:42 | gokhan | hi folks, I am currently testing OpenStack Epoxy with Masakari for instance high availability. In my lab environment, I am using Ceph RBD as the backend for Nova ephemeral disks and for cinder disks. I am performing "hard failure" tests by physically pulling the power plug of a compute node to trigger Masakari’s evacuation process. While Masakari successfully detects the failure and starts the instances on another node, I am facing sever | |
| 12:21:43 | gokhan | e filesystem corruption on almost all evacuated VMs.Upon recovery on the new node, VMs drop to emergency mode with blk_update_request: I/O error and journal corruption. I suspect network=writeback is the primary culprit during a hard power-off because volatile buffers are lost before being flushed to the Ceph OSDs. Is it a common consensus to avoid network=writeback when using Masakari or any HA driver that expects survival after a hard node crash? | |
| 12:21:43 | gokhan | What is the recommended disk_cachemodes for Ceph RBD in production environments where power-loss-induced HA is a requirement? Is network=none the only safe path? Would switching to virtio-scsi (with hw_scsi_model and hw_disk_bus) significantly improve the "flush" command reliability during sudden failures compared to standard virtio-blk? | |
| 12:23:59 | sean-k-mooney | gokhan: so i asume masakari is using evacuate. its a hard requiremt of using the evacuate api that the vm must be stopped on the orginal host and the admin or masikari in this case is requried to verify that before calling evacuate. by fencing i assume you mean that the phsyical host runing the vm is power off with ipmi/redfhist/pdu | |
| 12:24:28 | sean-k-mooney | network=writeback still commit all guest flushes to the backing store i.e. ceph | |
| 12:25:04 | sean-k-mooney | so if your guest os is properly flushing write then there shoudl not be any currption | |
| 12:25:43 | sean-k-mooney | or at least chanign to to none for the cache mode woudl not alter the flush behavior | |
| 12:27:21 | gokhan | thanks sean-k-mooney , Regarding your point on fencing: Yes, Masakari is indeed using the Evacuate API, and I am simulating a hard failure by physically pulling the power plug of the compute node (simulating a sudden power outage or a motherboard failure where no graceful shutdown or IPMI action is possible from the host side). | |
| 12:27:22 | sean-k-mooney | the production recomendation for ceph is hw_disk_bus=scsi hw_scsi_model=virtio-scsi and cash mode set to writeback | |
| 12:27:30 | sean-k-mooney | that is the recommendation form the ceph comunity | |
| 12:33:41 | sean-k-mooney | https://docs.ceph.com/en/latest/rbd/rbd-openstack/#image-properties https://docs.ceph.com/en/latest/rbd/rbd-openstack/#configuring-nova | |
| 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. | |
