| 13:46:30 | JulienCornuwel | efried: gibi: Thanks for the confirmation. We'll start working on a spec and thinking of a way to do that. | |
| 13:46:45 | efried | pooja_jadhav: So the instance is actually booting from volume - i.e. truly not using the local disk - but nova hypervisor-stats is showing that capacity as having been applied from the local disk? | |
| 13:46:50 | sean-k-mooney | oh you put the constatit in deps | |
| 13:46:54 | tssurya | mgariepy: well the aim of map_instances is to just map the instances to the cells, so if you have done it once, and you are sure all instances are mapped, I don't see any reason to keep running it, unless you have new ones to populate | |
| 13:47:08 | stephenfin | sean-k-mooney: Ah, I get it. You don't want to install your local package with constraints but you _do_ want to install your test requirements | |
| 13:47:14 | stephenfin | ...with them | |
| 13:47:15 | mgariepy | tssurya, https://github.com/openstack/openstack-ansible-os_nova/blob/stable/pike/tasks/nova_db_setup.yml#L58-L90 | |
| 13:47:18 | stephenfin | sean-k-mooney: yuuup | |
| 13:47:47 | efried | JulienCornuwel: Note that things involving the existing PCI passthrough subsystem are going to be difficult to get approval for, because we're trying to get rid of that whole thing. | |
| 13:47:54 | sean-k-mooney | stephenfin: yep | |
| 13:47:56 | mgariepy | so if the cell_v2 mapping was done in the upgrade, (and the create_cell returns 2, it would be right to skip the map_instances | |
| 13:48:39 | efried | JulienCornuwel: That said, I think you could do what you want without really hitting that code; and in such a way that it would be transferrable to placement-based device passthrough in the future. | |
| 13:48:39 | JulienCornuwel | efried: In favor of? Cyborg? | |
| 13:48:58 | pooja_jadhav | efried: After looking at the code changes done by Dan, its not taking disk_gb resource. When allocation candidates returns the response. | |
| 13:49:07 | efried | JulienCornuwel: Well, yes, but more generally placement. | |
| 13:49:17 | mordred | stephenfin, sean-k-mooney the trick is putting -c{env:UPPER_CONSTRAINTS_FILE:https://git.openstack.org/cgit/openstack/requirements/plain/upper-constraints.txt} into the deps list | |
| 13:49:19 | mordred | not the install_command | |
| 13:49:40 | tssurya | mgariepy: yes exactly | |
| 13:49:41 | sean-k-mooney | mordred: ya that is sneaky i like it | |
| 13:49:41 | mordred | like http://git.openstack.org/cgit/openstack/openstacksdk/tree/tox.ini | |
| 13:49:50 | mgariepy | thanks :) | |
| 13:50:06 | mordred | sean-k-mooney: it's the necessary trick for the self-constraint problem ;) | |
| 13:50:07 | tssurya | mgariepy: no problem | |
| 13:50:10 | efried | pooja_jadhav: It sounds like you should downvote the patch (it needs a rebase anyway, so you won't be the only thing holding it up) and explain what you're seeing. | |
| 13:50:33 | efried | pooja_jadhav: What would be even better is if you could come up with a functional test that demonstrates the behavior. | |
| 13:50:40 | mordred | tox installs the deps line separate from the current project - but it uses install_command for both things | |
| 13:50:52 | sean-k-mooney | mordred: it should also work on cygwin which the install script version did not | |
| 13:50:57 | mordred | so by putting constraints in deps, it winds up on the command line for the deps - but not for the install of the current project | |
| 13:51:01 | mordred | sean-k-mooney: yup | |
| 13:51:05 | pooja_jadhav | efried: But at https://github.com/openstack/nova/blob/master/nova/objects/build_request.py#L64 I can see in this db_instance the root_gb=1 value is going. | |
| 13:51:29 | mordred | sean-k-mooney: there are many reasons we don't like those install script wrappers - we forget to communicate all of them :) | |
| 13:52:07 | pooja_jadhav | efried: ok | |
| 13:52:28 | openstackgerrit | Takashi NATSUME proposed openstack/nova master: Transform volume.usage notification https://review.openstack.org/580345 | |
| 13:53:06 | JulienCornuwel | efried: thanks, we'll look into that | |
| 13:53:12 | sean-k-mooney | mordred: well os-vif never used the install script because it broke my cygwin workflow at the time. | |
| 13:53:31 | tssurya | jaypipes: you appear to be the only spec core online now; whenever you get the time could you please have a look at https://review.openstack.org/#/c/581243/ ? It a very easy not fix follow-up on a merged spec | |
| 13:53:54 | tssurya | nit* | |
| 13:54:36 | mordred | sean-k-mooney: \o/ | |
| 13:57:11 | openstackgerrit | Takashi NATSUME proposed openstack/nova master: Transform volume.usage notification https://review.openstack.org/580345 | |
| 13:59:23 | efried | There may still be a race in this setup, because there may be a delay before get_available_resource/update_provider_tree is run. I suppose you could get around this by making your spawn method add the device to the "reserved" list, and then have your notification listener thingy only be responsible for removing it when done. | |
| 13:59:23 | efried | So when we make the move to placement-based device reporting, the latter logic would go into update_provider_tree instead of get_available_resource, but everything else would stay the same. | |
| 13:59:23 | efried | JulienCornuwel: To be a bit more specific: your notification listener would conceivably start the cleanup process, and also register the device in some kind of cache ("reserved devices"). Add logic to your get_available_resource method to look at that cache and skip reporting any devices therein. | |
| 13:59:38 | openstackgerrit | sean mooney proposed openstack/os-vif master: add upper_constraitns support https://review.openstack.org/583582 | |
| 14:00:12 | sean-k-mooney | we should backport ^ | |
| 14:01:48 | sean-k-mooney | ok going to grab lunch brb | |
| 14:02:09 | openstackgerrit | do3meli proposed openstack/nova master: docs: add nova host-evacuate command to evacuate documentation https://review.openstack.org/578040 | |
| 14:06:12 | efried | sean-k-mooney: We should spell it right, though. | |
| 14:08:01 | stephenfin | efried: It's the main reason we keep jaypipes around, tbh | |
| 14:08:03 | sean-k-mooney | dambit hehe ill fix that when i get back | |
| 14:08:16 | efried | sean-k-mooney: I'll push the edit right quick. | |
| 14:08:39 | openstackgerrit | Eric Fried proposed openstack/os-vif master: add upper_constraints support https://review.openstack.org/583582 | |
| 14:08:43 | stephenfin | spellchecker extraordinaire | |
| 14:09:02 | efried | sean-k-mooney: +2 | |
| 14:09:18 | openstackgerrit | Matt Riedemann proposed openstack/os-vif master: add upper_constraints support https://review.openstack.org/583582 | |
| 14:09:33 | efried | mriedem: wtf, yo | |
| 14:10:23 | stephenfin | efried: It's alright - we'd missed anyway | |
| 14:10:59 | sean-k-mooney | mriedem: yes you are right ill fix those | |
| 14:11:13 | efried | I'm still not clear that we care about upper constraints (or constraitns or constranits) for doc builds, but okay. | |
| 14:12:12 | sean-k-mooney | oh the pti change has merged that why i missed the others | |
| 14:12:40 | jaypipes | stephenfin: glad to be of service. :) | |
| 14:12:41 | sean-k-mooney | ok got to run to shop back in 15 min ill fix it all up then | |
| 14:13:25 | stephenfin | efried: Yeah, I'm on the fence myself about them, despite suggesting it in the first place | |
| 14:13:52 | jaypipes | tssurya: done! | |
| 14:22:17 | openstackgerrit | Takashi NATSUME proposed openstack/nova master: Transform libvirt.error notification https://review.openstack.org/484851 | |
| 14:23:48 | mriedem | tssurya: the handling a down cell changes seem to be kind of all over the place, can you rebase those into a series? | |
| 14:23:54 | mriedem | where the api changes with the microversion come at the end? | |
| 14:24:34 | mriedem | i would do in this order: object change for queued_for_delete -> online data migration -> setting queued_for_delete -> handling a down cell + microversion | |
| 14:29:11 | efried | pooja_jadhav: Are you using DiskFilter? | |
| 14:30:00 | pooja_jadhav | pooja_jadhav: I have checked nova.conf, also nova-cpu.conf.. in that in enable_filters there is no any DiskFilter is added. | |
| 14:30:52 | openstackgerrit | Matt Riedemann proposed openstack/python-novaclient master: Microversion 2.64 - Use new format policy in server group https://review.openstack.org/578261 | |
| 14:30:53 | openstackgerrit | Matt Riedemann proposed openstack/python-novaclient master: Add support for microversion 2.65 https://review.openstack.org/583632 | |
| 14:32:25 | mriedem | pooja_jadhav: which release are you on? | |
| 14:32:26 | openstackgerrit | Merged openstack/nova-specs master: Fix nits in the handling down cell spec https://review.openstack.org/581243 | |
| 14:32:39 | mriedem | master? | |
| 14:32:44 | pooja_jadhav | pooja_jadhav: Current master | |
| 14:33:07 | pooja_jadhav | mriedem: from cuurent master, fetched patch | |
| 14:33:23 | pooja_jadhav | using latest code | |
| 14:33:34 | mriedem | and you boot from volume and nova hypervisor-stats is showing local_gb_used=1? | |
| 14:33:42 | pooja_jadhav | yes | |
| 14:33:54 | mriedem | are you using devstack? | |
| 14:33:58 | pooja_jadhav | yes | |
| 14:34:23 | mriedem | and libvirt driver correct? | |
| 14:34:28 | pooja_jadhav | yes | |
| 14:34:36 | mriedem | does the flavor have ephemeral_gb? | |
| 14:35:23 | pooja_jadhav | using flavor 1 (ephemeral_gb=0, swap=0) | |
| 14:35:31 | mriedem | what is reserved_host_disk_mb set to in nova-cpu.conf? | |
| 14:36:20 | pooja_jadhav | not set any value | |
| 14:36:54 | tssurya | jaypipes: thanks | |
| 14:37:47 | mriedem | pooja_jadhav: efried: oh i see exactly why | |
| 14:38:13 | efried | mriedem: Do tell. I've been staring at this and slowly gleaning understanding, but am still out of my depth. | |
| 14:38:18 | mriedem | https://github.com/openstack/nova/blob/eb4f65a7951e921b1cd8d05713e144e72f2f254f/nova/compute/resource_tracker.py#L1455 | |
| 14:38:26 | mriedem | the usage dict doesn't know about bfv | |
| 14:38:57 | mriedem | pooja_jadhav: can you check the resource allocations for that instance to make sure DISK_GB is unset or 0? | |
| 14:39:19 | mriedem | pooja_jadhav: https://docs.openstack.org/osc-placement/latest/cli/index.html#resource-provider-allocation-show | |
| 14:39:32 | mriedem | openstack resource provider allocation show <instance uuid> | |
| 14:39:35 | tssurya | mriedem: so the what I have it now is change for qfd -> migration and setting qfd sit on this. The patch for API changes is just a POC/WIP for nova list which I am working on to include the nova show as well. | |
| 14:39:37 | mriedem | DISK_GB should either not be there or 0 | |
| 14:39:52 | tssurya | the way* | |
| 14:40:03 | pooja_jadhav | allocation_candidates not returning DISK_GB | |
| 14:40:06 | mriedem | tssurya: right i don't like how the series diverges | |
