| 16:35:53 | sean-k-mooney | spatel: there are pros and cons. you are trading scaleableity for grater message que load | |
| 16:36:09 | spatel | hmm! | |
| 16:36:28 | sean-k-mooney | if you go the rabbit route i would personally have a different rabbitmq server to not impact your openstack performance | |
| 16:36:41 | sean-k-mooney | but i would start with going direct to infuxdb | |
| 16:37:04 | spatel | ++ for direct to influxdb | |
| 16:37:17 | spatel | I am new so i don't want to make it extra complex.. :) | |
| 16:37:34 | spatel | i will go with rabbitmq when my cloud will be 1000 compute node | |
| 16:38:12 | spatel | Thanks!! folks it was very helpful.. | |
| 16:38:13 | sean-k-mooney | ralonsoh: do you know how mature the baromater installer is. it supports deploying collect+infux+graphan correct in containers | |
| 16:38:43 | sean-k-mooney | spatel: glad we could help. its always better to start simple :) | |
| 16:38:51 | spatel | yup! | |
| 16:39:07 | ralonsoh | sean-k-mooney, Emma was working actively in this project. I don't even know where can I download it! | |
| 16:40:47 | sean-k-mooney | its amazing how in big companiens 2 people can be sitting 3 meters from each other and be working on totoally different things. no worries | |
| 16:41:38 | sean-k-mooney | spatel: by the way you are using openstack ansible. correct its proably worth poping over to there irc channel and asking them if they have any supported monitoring solutions and what the recommend too | |
| 16:43:42 | spatel | I did ask and they do have some stuff but not very documented and don't know if folks using them or not https://github.com/openstack/openstack-ansible-ops/blob/master/cluster_metrics/playbook-influx-db.yml | |
| 16:44:24 | spatel | Let me poke around and will see how it goes... | |

| 06:58:11 | sean-k-mooney | the summit starts in 1 hour right? at least the keynote should? | |
| 06:58:58 | sean-k-mooney | or it could have stared yesterday... | |
| 07:17:14 | tetsuro | sean-k-mooney: The summit started yesterday. The keynote of Day 2 starts in 1 hour. | |
| 07:17:39 | sean-k-mooney | tetsuro: hehe yes i started watching the youtube vids | |
| 07:18:08 | sean-k-mooney | tetsuro: are you at the summit this time | |
| 07:18:24 | tetsuro | Yes I am, but I didn't see you. | |
| 07:18:43 | tetsuro | you aren't this time? | |
| 07:19:14 | sean-k-mooney | no i choose not to travel this time as i have done quite alot of travel, at least for me already this year | |
| 07:19:45 | tetsuro | I see. I hope I can see you next Denver :) | |
| 07:19:55 | tetsuro | Anyway, gotta leave the hotel | |
| 07:20:09 | sean-k-mooney | yes same, im hoping to be in denver. enjoy | |
| 07:20:21 | tetsuro | bye. | |
| 07:41:31 | openstackgerrit | Matt Riedemann proposed openstack/nova master: Add DownCellFixture https://review.openstack.org/614810 | |
| 07:59:25 | openstackgerrit | Dan Smith proposed openstack/nova master: Add CellsV2 FAQ about API design decisions https://review.openstack.org/617898 | |
| 08:08:14 | mriedem | dansmith: this is pretty simple, something we talked about at the ptg to fix a few issues in scheduling to a specific node https://review.openstack.org/#/c/603585/ | |
| 08:16:59 | dansmith | mriedem: okay I +Wd the spec, but I wish it included more about the actual nova side that actually solves a problem instead of just a placement-side API that _could_ be used to solve a problem | |
| 08:18:48 | sean-k-mooney | dansmith: the usecase we discussed at the ptg was related to numa affinity right | |
| 08:19:29 | dansmith | sean-k-mooney: no | |
| 08:19:41 | dansmith | sean-k-mooney: boot or live migration with a target host | |
| 08:20:14 | sean-k-mooney | dansmith: the in_tree paramater? | |
| 08:20:41 | mriedem | correct | |
| 08:20:45 | mriedem | or rebuild with an image change | |
| 08:20:54 | mriedem | or evac with a target host | |
| 08:21:06 | mriedem | or cold migrate with a target host... :) | |
| 08:21:27 | sean-k-mooney | on the in_tree is set to the compute node uuid | |
| 08:21:36 | sean-k-mooney | ya that makes sense too | |
| 08:22:18 | openstackgerrit | Merged openstack/nova-specs master: Spec: allocation candidates in tree https://review.openstack.org/603585 | |
| 08:45:52 | mriedem | jroll: just some updates on https://review.openstack.org/#/c/609709/ and i'm happy | |
| 08:58:57 | openstackgerrit | sean mooney proposed openstack/os-vif master: always create ovs port during plug https://review.openstack.org/602384 | |

| 09:34:34 | openstackgerrit | Ivaylo Mitev proposed openstack/nova master: VMware: Attach volumes using adapter type from instance https://review.openstack.org/616599 | |
| 09:39:07 | jroll | mriedem: yep, doing it this morning | |
| 09:57:24 | mriedem | Kevin_Zheng: when you get a chance, can you update the root volume detach spec with the resize issue i told you about the other night? https://review.openstack.org/#/c/600628/ | |
| 09:58:31 | Kevin_Zheng | mriedem: Oh the spec, go it, I was only thinking about the implementation | |
| 10:04:42 | mriedem | i just want to make sure it's recorded in the spec so we don't forget about it during review | |
| 10:04:48 | mriedem | since the unshelve/start limitations are listed in the spec | |
| 10:05:00 | openstackgerrit | Jim Rollenhagen proposed openstack/nova-specs master: Use conductor groups to partition nova-compute services for Ironic https://review.openstack.org/609709 | |
| 10:05:02 | mriedem | resize revert/confirm would have the same limitations - fail if there is no root volume | |
| 10:05:43 | jroll | mriedem: ^ should finally be good to go there now | |
| 10:07:23 | mriedem | ack | |
| 10:07:43 | mriedem | sean-k-mooney: if you want to follow along https://etherpad.openstack.org/p/BER-nfv-hpc-pain-points | |

| 10:09:31 | sean-k-mooney | mriedem: yep i already had it open :) | |
| 10:21:10 | openstackgerrit | Balazs Gibizer proposed openstack/nova master: Test boot with more ports with bandwidth request https://review.openstack.org/573317 | |
| 10:26:28 | mriedem | logan-: did you get that resize bug opened? | |
| 10:44:02 | sean-k-mooney | looks like there was a good conversation in https://etherpad.openstack.org/p/BER-nfv-hpc-pain-points | |
| 11:13:08 | logan- | mriedem: https://bugs.launchpad.net/nova/+bug/1803331 | |
| 11:13:08 | openstack | Launchpad bug 1803331 in OpenStack Compute (nova) "Root disk lost when resizing instance from imagebackend to rbd backed flavor" [Undecided,New] | |
| 11:20:19 | lyarwood | logan-: https://review.openstack.org/#/c/578846/ might resolve that assuming this is a cause of us cleaning up aggresively after a failure, hard to tell from the trace alone. | |
| 11:22:53 | sean-k-mooney | logan-: how do you have an RBD backed flavor? isnt the storage backend determined by the nova.conf not the flaovor? | |
| 11:23:42 | lyarwood | sean-k-mooney: host aggregates | |
| 11:24:19 | sean-k-mooney | lyarwood: right but just because you are afinities flaovrs to host aggrages and that chnages your network backend does not mean this is related to flaovrs | |
| 11:24:23 | openstackgerrit | Sean McGinnis proposed openstack/nova master: Remove v1 check in Cinder client version lookup https://review.openstack.org/617927 | |
| 11:25:05 | sean-k-mooney | this is simply a bug with rezieing between image backed nodes and rbd nodes | |
| 11:25:08 | lyarwood | sean-k-mooney: imagebackend and yeah agreed I was just passing on what was described in the bug | |
| 11:25:30 | lyarwood | sean-k-mooney: this is all imagebackend, I'm not sure why logan- has called one out as imagebackend and the other as rbd | |
| 11:25:31 | mdbooth | lyarwood: reading | |
| 11:26:59 | sean-k-mooney | reading the bug it seams the issues is with migrating from imagebacked nodes to rbd backed nodes no? | |
| 11:27:01 | logan- | Sorry if it is confusing. Yes these are different nodes with different storage backends configured in nova.conf | |
| 11:27:14 | logan- | sean-k-mooney: correct | |
| 11:27:22 | sean-k-mooney | i would assume the same behavior would exist if you just migrated and did not reszie | |
| 11:27:25 | mdbooth | Sounds like there's 2 issues there | |
| 11:27:41 | mdbooth | Firstly, resizing between compute hosts using different imagebackends isn't supported | |
| 11:28:07 | openstackgerrit | Balazs Gibizer proposed openstack/nova master: Pass allocations and traits to neturonv2 api https://review.openstack.org/616240 | |
| 11:28:07 | openstackgerrit | Balazs Gibizer proposed openstack/nova master: Send RP uuid in the port binding https://review.openstack.org/569459 | |
| 11:28:08 | openstackgerrit | Balazs Gibizer proposed openstack/nova master: Test boot with more ports with bandwidth request https://review.openstack.org/573317 | |
| 11:28:11 | mdbooth | So, I guess that's not an issue, except that we could do better at preventing the attempt | |
| 11:28:19 | mdbooth | I think sean-k-mooney mentioned that the other week. | |
| 11:28:25 | logan- | mdbooth: right, I don’t expect it to be. I just expect it to fail and not destroy the instance :) | |
| 11:28:35 | mdbooth | Secondly, we seem to have lost the root disk, which is extremely bad | |
| 11:28:58 | sean-k-mooney | logan-: i actully dont think its unresobaly to support we jsut dont today | |
| 11:29:47 | mdbooth | sean-k-mooney: Conceptually it's not unreasonable, it's just that the imagebackend code is utterly awful. | |
