| 13:26:17 | jaypipes | efried: no, feel free to respin. I think you got most of my feedback on IRC on that one, yeah? | |
| 13:26:22 | alex_xu | s/something/sometime/ | |
| 13:26:26 | jaypipes | alex_xu: working it right now :) | |
| 13:26:39 | efried | jaypipes Hopefully. Respinning now... | |
| 13:28:51 | jaypipes | alex_xu: nighty night! :)( | |
| 13:29:03 | jaypipes | cdent: +W'd | |
| 13:39:33 | efried | jaypipes You said the order of subclauses in an AND isn't important... so the database doesn't short-circuit the clause on the first false condition? | |
| 13:40:27 | jaypipes | efried: no, it doesn't work that way. RDBMs will always prioritize the field(s) that are in indexes chosen by the query optimizer. | |
| 13:40:47 | efried | hm, neat. | |
| 13:41:23 | jaypipes | efried: so in that case, it makes no difference since the resource class and resource provider fields will always be evaluated before anything with total, max_unit, step_size, or min_unit | |
| 13:42:14 | efried | jaypipes But it's (slightly) cheaper to do the single-comparator math than the multiple-add-compare stuff. | |
| 13:42:38 | efried | multiply-add-compare, that is. | |
| 13:42:44 | efried | I'm sure it's negligible. | |
| 13:42:52 | jaypipes | efried: I don't think you'd see the difference there, no. | |
| 13:43:25 | jaypipes | efried: compared to the cost of loading all of the fields into memory after the join conditions are satisfied, the comparison of the data in those loaded fields is miniscule. | |

| 14:32:41 | reedip_ | Hi guys , how much time does it take for an instance to boot up in Nova ? We have a 32 GB RAM for Compute node, and booting up a VM using Ubuntu 14.04 | |
| 14:32:53 | reedip_ | but the VM doesnt boot up in 6 minutes.... | |
| 14:33:00 | reedip_ | does that normally occur ? | |
| 14:33:16 | reedip_ | I tried it atleast 8-10 times , booting a set of 10 VMs. | |
| 14:33:32 | reedip_ | each VM is an Ubuntu Xenial CLoud image | |
| 14:34:13 | reedip_ | but of the 10 VMs, 4-6 boot up succesfully... failure occurs after that | |
| 14:34:23 | reedip_ | Flavor given is 2 GB RAM and 3 GB HDD | |
| 14:35:19 | jaypipes | reedip_: 14.72917672 seconds. every time. | |
| 14:35:39 | reedip_ | jaypipes : its that accurate ???? | |
| 14:36:06 | jaypipes | reedip_: no, of course not, I was only joking... :) there's no way to say. totally depends on the hardware, the virt driver, the number of nodes, etc etc | |
| 14:36:09 | reedip_ | jaypipes : so if a VM doesnt boot up ( BTW I am using Mitaka with Ubuntu 14.04 ), where can I find the logs ? | |
| 14:36:35 | reedip_ | jaypipes : I thought so :) | |
| 14:37:03 | jaypipes | reedip_: look in the nova-scheduler logs. you will likely find an error about resources being over capacity... | |
| 14:37:17 | reedip_ | jaypipes : okay, let me check ... | |
| 14:38:37 | jaypipes | reedip_: for a small setup like that, if the VM doesn't boot in under 15 seconds, that's unusual... | |
| 14:39:05 | reedip_ | jaypipes : wait, the complete setup is below : | |
| 14:39:14 | jaypipes | for tiny images like that, I'd expect something more like 6 seconds, especially if the image has already been launched/cached on the comput ehost. | |
| 14:39:23 | reedip_ | 1 Controller: 4 GB RAM, 12 GB HDD | |
| 14:41:43 | jaypipes | reedip_: how many compute nodes? | |
| 14:42:48 | openstackgerrit | Eric Berglund proposed openstack/nova master: PowerVM Driver: config drive https://review.openstack.org/409404 | |
| 14:42:48 | jaypipes | reedip_: also, your instances should end up in an ERROR state if they aren't booting in six minutes. You should be able to check the error by looking at the instance faults returned in the GET /servers/{uuid}/detail call. | |
| 14:49:06 | reedip_ | jaypipes : hi , did you get my earlier messages ? | |
| 14:49:26 | jaypipes | reedip_: err, no? | |
| 14:50:56 | reedip_ | jaypipes : sorry then, my network issue ... | |
| 14:51:04 | reedip_ | jaypipes : the complete setup is below : | |
| 14:51:41 | reedip_ | jaypipes :1 Controller: 4 GB RAM, 12 GB HDD, 3 Compute : 2 COmpute with 32 GB RAM and 100 GB HDD , 1 with 8 GB RAM and 20 GB HDD, 1 Glance server ,The request goes to the 100 GB COmpute machine, and we are using Qemu | |
| 14:52:41 | reedip_ | jaypipes : would Nova-Scheduler report it as an Error ?? I think it should but reconfirming | |
| 14:52:48 | jaypipes | reedip_: what are your allocation ratios? have you changed any of the default configuration values for cpu_allocation_ratio, ram_allocation_ratio or disk_alllocation_ratio? | |
| 14:52:54 | reedip_ | jaypipes : in case resources are less | |
| 14:53:07 | reedip_ | jaypipes : no , not changed any default configurations | |
| 14:53:13 | jaypipes | reedip_: yes. you would see a NoValidHost pop up. | |
| 14:53:17 | jaypipes | reedip_: k | |
| 14:53:48 | jaypipes | reedip_: look in the nova-scheduler and nova-compute log files. nova-scheduler on controller. nova-compute on each of the compute nodes. look for any ERROR log line. | |
| 14:53:55 | reedip_ | jaypipes : yeah, couldnt find that ... I know the NoValidHost error , happened to me amny a times now .. :) | |
| 14:55:49 | jaypipes | reedip_: you see no errors at all? | |
| 14:57:16 | reedip_ | jaypipes : no , I couldnt see the NoValidHost error .. there are some rabbitmq errors but that was because rabbitmq was failed ... this happened quite a long time after we noticed the VM failure, so I dont think that would be an issue | |
| 14:58:49 | jaypipes | reedip_: rabbit errors would definitely be an issue... | |

| 14:59:23 | reedip_ | we resolved them , and retried the tests, but still got the failure, thats why I am thinking if it is or not | |
| 14:59:28 | reedip_ | jaypipes: ^^ | |
| 14:59:54 | edleafe | mriedem: dansmith: ^^ refactored with additional RPC param | |
| 15:01:03 | jaypipes | reedip_: on a call for an hour or so.. | |
| 15:01:06 | reedip_ | jaypipes : I may need to leave soon, but I will see the logs and accordingly report it on the launchpad. Maybe we can proceed from there ... is that ok ? | |
