| 14:17:19 | bauzas | if I was just providing the string like this | |
| 14:17:45 | bauzas | 'herv\xc3\xa9' | |
| 14:21:31 | openstackgerrit | Gábor Antal proposed openstack/nova master: Transform instance.live_migration_rollback notification https://review.openstack.org/402124 | |
| 14:21:51 | d3n14l | Can someone tell me why a `openstack server list`repeatedly takes >15s for "just" 200 servers? (On openstack-ansible deployment, configured memcache and no slow request on the galera cluster…) See https://pastebin.com/nMivFhMA | |
| 14:23:55 | openstackgerrit | Gábor Antal proposed openstack/nova master: Transform instance.live_migration_rollback notification https://review.openstack.org/402124 | |
| 14:23:59 | kashyap | sdague: Thank you | |
| 14:24:45 | openstackgerrit | Merged openstack/python-novaclient master: Prevent 2.32 release note from showing up in 9.0.0 release notes https://review.openstack.org/471383 | |
| 14:24:49 | kashyap | sdague: Is this a "pure DevStack" host? | |
| 14:25:14 | kashyap | sdague: Because your setup is consuming 4.5 GB of memory; if you saw mine above, it was operating with 2.5GB | |
| 14:25:25 | sdague | kashyap: it is | |
| 14:25:34 | sdague | it's also been running for some amount of time | |
| 14:26:15 | kashyap | Noted; thanks | |
| 14:26:39 | sdague | while it never had a tempest run, I was doing some testing with guests booting so it's had about 30 - 40 cirros guests boot / delete | |
| 14:31:17 | kashyap | Ah | |
| 14:31:26 | kashyap | sdague: Any improvement with this: `free -m && sync && echo 3 > /proc/sys/vm/drop_caches && free -m` | |
| 14:31:32 | kashyap | As root | |
| 14:34:07 | sdague | kashyap: well that dumped my buffer cache | |
| 14:34:15 | sdague | but it doesn't change the ps_mem output | |
| 14:34:36 | kashyap | sdague: Whoops, thought you've read the line. That's why I didn't explain it, sorry :-( | |
| 14:34:49 | kashyap | But thank you for testing | |
| 14:35:05 | sdague | kashyap: what did you think I read? | |
| 14:35:25 | kashyap | The command sequence in quotes | |
| 14:35:25 | sdague | kashyap: what was your intent with the free calls? | |
| 14:35:48 | sdague | kashyap: sure, I guess I'm just not sure what you were asking for as "improvement" | |
| 14:35:51 | kashyap | Just to see if dropping 'needless' things in the caches will show what's the bare-minimal memory occupation | |
| 14:36:12 | sdague | but thats FS cache right? | |
| 14:36:27 | sdague | that's not going to impact any program mem usage | |
| 14:37:59 | kashyap | sdague: That's freeing page cache | |
| 14:38:10 | sdague | kashyap: yes | |
| 14:38:43 | sdague | kashyap: sorry, I guess I'm just not sure what you are asking when you asked about "improvement" | |
| 14:38:50 | sdague | what were you expecting? | |
| 14:38:56 | sdague | that you wanted me to verify | |
| 14:39:24 | kashyap | sdague: I think I erroneously thought it'll have effect on program memory usage | |
| 14:39:41 | kashyap | So just talking out loud, your brain spelled my stupidity out. | |
| 14:39:41 | openstackgerrit | Merged openstack/python-novaclient master: Updated from global requirements https://review.openstack.org/469581 | |
| 14:47:13 | openstackgerrit | Jianghua Wang proposed openstack/nova master: Fix the race condition with novnc https://review.openstack.org/470798 | |
| 15:00:35 | openstackgerrit | Andrey Volkov proposed openstack/nova master: [placement] Add api-ref for aggregates https://review.openstack.org/470932 | |
| 15:00:35 | openstackgerrit | Andrey Volkov proposed openstack/nova master: [WIP] [placement] Add api-ref for allocations https://review.openstack.org/470933 | |
| 15:08:08 | openstackgerrit | Baodong (Robert) Li proposed openstack/nova-specs master: Expose vlan trunking in metadata/configdrive https://review.openstack.org/471815 | |
| 15:12:18 | mriedem | good lord there are just way too many config options for libvirt live migratoin | |
| 15:12:19 | mriedem | *migration | |
| 15:12:32 | mriedem | the help for some of them even reference things that no longer exist, which is helpful | |
| 15:14:39 | openstackgerrit | Gábor Antal proposed openstack/nova master: Move rebuild notification tests into separate method https://review.openstack.org/451789 | |
| 15:20:00 | kashyap | mriedem: How many are you counting? | |
| 15:20:13 | mriedem | "a bazillion" is what my email to the ML is going to say | |
| 15:20:32 | kashyap | Heh, everything looks useful when you read one-by-one, doesn't it | |
| 15:21:00 | mriedem | sent | |
| 15:21:19 | mriedem | i took some artistic freedoms in language toward the end | |
| 15:21:24 | kashyap | :-) | |
| 15:21:54 | kashyap | But yeah, more seriously, exposing every frelling knob that libvirt has (which explicitly *doesn't* make policy decisions, by design) is not desirable | |
| 15:22:13 | kashyap | Must probaby turn some of them into defaults | |
| 15:23:30 | mriedem | s/landmine/minefield/ d'oh | |
| 15:23:45 | mriedem | well i'll see if i can cleanup some of these options | |
| 15:23:47 | mriedem | help-wise | |
| 15:24:02 | dansmith | landfill? | |
| 15:24:15 | mriedem | tire fire | |
| 15:24:54 | jaypipes | mriedem: there's way too many Nova config options for libvirt live migration because there's way too many configuration options for libvirt live migration. period... | |
| 15:25:52 | mriedem | the heart wants what it wants jay | |
| 15:25:58 | mriedem | and it wants mfing config options | |
| 15:26:10 | kashyap | The Nova time-outs and re-tries seemed to be the ones that can be removed? | |
| 15:26:25 | gbarros | mriedem I see that you +2 mhenkel's vif patch. Could you take a peek at the blueprint also pls? | |
| 15:26:40 | gbarros | mriedem https://blueprints.launchpad.net/nova/+spec/opencontrail-nova-vif-plugin | |
| 15:26:42 | kashyap | Err, before someone jumps on me, "removed" as in ... "can they be reconsiderd" | |
| 15:27:47 | mriedem | gbarros: as in approve the bp? | |
| 15:27:51 | mriedem | btw, -2 on the stable/ocata backport | |
| 15:27:56 | mriedem | we don't backport features | |
| 15:28:20 | gbarros | mriedem, on the bp, if it looks ok to you. | |
| 15:28:38 | gbarros | mriedem, ack on -2 for the backport. It was worth a shot :) | |
| 15:29:27 | openstackgerrit | Baodong (Robert) Li proposed openstack/nova-specs master: Expose vlan trunking in metadata/configdrive https://review.openstack.org/471815 | |
| 15:29:57 | gbarros | mriedem, on the backport I'm mostly wanting to see if it will pass CI. | |
| 15:30:06 | jaypipes | kashyap: if there was a stable and consistently-converging live-migration interface in libvirt, those options wouldn't be needed. :) | |
| 15:30:09 | mriedem | gbarros: approved the bp, i forgot about that one | |
| 15:30:14 | gbarros | mriedem ty! | |
| 15:30:20 | cdent | jaypipes: i'm a bit confused and concerned about your lack of concern on the conusmer uuid thing, especially if the fix is doing and update or insert instead of what's there now? | |
| 15:30:24 | kashyap | jaypipes: Nod... | |
| 15:30:36 | mriedem | gbarros: mhenkel: now you just need to get jaypipes to review the chnage | |
| 15:30:37 | jaypipes | cdent: I'm not concerned *for that patch*. | |
| 15:30:38 | mriedem | *change | |
| 15:31:01 | jaypipes | cdent: nobody other than Nova is yet writing allocations. we can add a patch in the future to handle that situation. | |
| 15:31:14 | kashyap | jaypipes: I also wonder if this can be elided - 'live_migration_inbound_addr' | |
| 15:31:28 | jaypipes | cdent: I don't want to hold things up endlessly trying to figure out the perfect solution for everything in the future, that's all. | |
| 15:31:51 | jaypipes | cdent: especially since we're running out of time quickly for Pike. | |
| 15:33:09 | cdent | jaypipes: agreed it would be nice to get this done, but this doesn't need a perfect solution, it just needs normal SQL... | |
| 15:33:57 | cdent | I think the code has a bug. Not an architecture confusion (like over in the how to deal with complex allocations thread). Those are different types of concerns. | |
| 15:34:07 | gbarros | jaypipes, at your convenience :) https://review.openstack.org/#/c/441183/ | |
| 15:34:31 | jaypipes | cdent: would you mind taking a looksie at melwitt's https://review.openstack.org/#/c/469634/10 test failure on _test_sync_traits()? | |
| 15:35:01 | jaypipes | cdent: why can't this be done in a patch after the one in question? | |
| 15:35:25 | cdent | jaypipes: we fixed that late last night with: https://review.openstack.org/#/c/471508/ | |
| 15:35:55 | openstackgerrit | Gábor Antal proposed openstack/nova master: Move rebuild notification tests into separate method https://review.openstack.org/451789 | |
| 15:35:56 | cdent | jaypipes: we can, that would be fine, but we have to agree to do so | |
| 15:37:27 | gabor_antal | sfinucan, oomichi: Would you please give back +2 on https://review.openstack.org/#/c/451789 ? I had to rebase it manually. | |
| 15:37:29 | jaypipes | cdent: I agree to do so. :) | |
| 15:37:38 | jaypipes | cdent: ok, cool (on the testsync traits thing) | |
| 15:38:11 | cdent | awesome, thanks jaypipes, that's more than I hoped for | |
| 15:38:19 | jaypipes | gbarros: you know what would make reviewing that easier? more than 0 lines of documentation on the opencontrail vif plugin repo :) | |
| 15:38:57 | gbarros | jaypipes, tell me about it :) mhenkel keeps telling me it's fully documented... somewhere... :) | |
| 15:40:05 | gbarros | mhenkel, could you help us out by pointing out the docs? Maybe a link to it in the readme? | |
| 15:40:21 | jaypipes | mriedem, gbarros: I thought I remembered some conversation where we wanted to make "vhostuser_vrouter_plug" mention contrail specifically before we merged this patch? | |
| 15:40:52 | jaypipes | gbarros: or is vhostuser_vrouter_plug already in the Neutron vif details and we can't change it? | |
| 15:40:58 | mriedem | jaypipes: the latter | |
