| 17:41:56 | sean-k-mooney | yes neutron allows you to add multiple subnets to the same network | |
| 17:42:19 | sean-k-mooney | you will need to add the second subnet to the router also | |
| 17:43:29 | spatel | I have VLAN base networking not tenant base.. | |
| 17:43:44 | spatel | This is the command i used to create my first subnet.. | |
| 17:43:48 | spatel | neutron subnet-create net_pub_vlan_200 71.xxx.xxx.0/24 --name sub_pub_vlan_200 --allocation-pool start=71.xxx.xxx.2,end=71.xxx.xxx.254 --dns-nameservers 8.8.8.8 --gateway=71.xxx.xxx.1 | |
| 17:44:17 | sean-k-mooney | spatel: we should peroably swap to the neutron channel but that is fine | |
| 17:45:03 | sean-k-mooney | vlan networks are still teant networks the terminology is a littel overloaded | |
| 17:45:10 | spatel | You are saying i add just add new public IP in same "net_pub_vlan_200" network? | |
| 17:45:55 | sean-k-mooney | yes you can | |
| 17:46:15 | spatel | Something like this? | |
| 17:46:36 | spatel | neutron subnet-create net_pub_vlan_200 72.xxx.xxx.0/24 --name new_subnet_vlan_200 --allocation-pool start=72.xxx.xxx.2,end=72.xxx.xxx.254 --dns-nameservers 8.8.8.8 --gateway=72.xxx.xxx.1 | |
| 17:46:55 | sean-k-mooney | yep | |
| 17:46:58 | spatel | net_pub_vlan_200 will be same right? | |
| 17:47:13 | spatel | perfect!! thanks for confirmation :) | |
| 17:47:46 | sean-k-mooney | the only other thing you need to do is add a new prot to the openstack or phyical router to connect to the new subnet | |
| 17:48:07 | spatel | new port? | |
| 17:49:09 | sean-k-mooney | if you are using a phyical provider router you need to asing 72.xxx.xxx.1 to it so it can act as a gatway but if you are using neutron routers then you just need to add a port on the neutron router to connet to n 72 subnet | |
| 17:50:45 | spatel | oh! yes i am running HSRP so yes.. i have to setup HSRP on my gateway switches :) | |
| 17:50:52 | sean-k-mooney | spatel: you can use the openstack router add subnet <route> 72.xxx.xxx.2 | |
| 17:52:10 | sean-k-mooney | ah ok then ya you are using phyical routers instead of neutron routers for you public network so you can skip the openstack router add subnet command | |
| 17:59:21 | spatel | yes!! | |
| 18:00:04 | spatel | sean-k-mooney: quick question, now i am planning to build new Openstack cloud with NATing style floating ip, not VLAN base | |
| 18:00:31 | spatel | how do i scale that network? we have super high PPS rate in network... does virtual router can handle that traffic? | |
| 18:00:47 | spatel | I have option for DVR | |
| 18:01:59 | sean-k-mooney | spatel: lets take the converstation to #openstack-neutron | |
| 18:06:50 | spatel | sean-k-mooney: thanks :) | |
| 18:07:50 | mriedem | dansmith: can you think of anything besides flavor that we would have data migrated from system_metadata in the meta-api? i was thinking keypairs but that was different i think - it was a separate table and the data was migrated to extras | |
| 18:08:16 | dansmith | yeah, not keypairs | |
| 18:08:34 | dansmith | nothing off the top of my head, but I haven't thought about it much | |
| 18:18:31 | openstackgerrit | Matt Riedemann proposed openstack/nova master: Be smarter about DB joins in the metadata API https://review.openstack.org/624778 | |
| 18:18:32 | mriedem | easy peasy ^ | |
| 18:47:15 | openstackgerrit | Chris Dent proposed openstack/nova master: Use external placement in functional tests https://review.openstack.org/617941 | |
| 18:50:24 | openstackgerrit | Chris Dent proposed openstack/nova master: Delete the placement code https://review.openstack.org/618215 | |
| 21:08:30 | openstackgerrit | Matt Riedemann proposed openstack/nova stable/rocky: Handle tags in _bury_in_cell0 https://review.openstack.org/624813 | |
| 21:43:47 | brandor5 | hello everyone: can anyone tell me where I can find the newton nova api reference? | |
| 21:48:07 | jonher | brandor5: this? https://developer.openstack.org/api-ref/compute/ | |
| 21:48:31 | brandor5 | jonher: that's latest, I need the one for newton | |
| 21:49:07 | brandor5 | I'm trying to use the api to confirmResize after a migrate and I'm getting an error | |
| 21:49:16 | brandor5 | Cannot 'confirmResize' instance e1782f5c-7559-4cac-a628-6d4a75a015f4 while it is in vm_state stopped | |
| 21:50:04 | brandor5 | If i run `nova resize-confirm <instance_id>` it works and I'm running the same curl that it runs... | |
| 21:51:05 | mriedem | brandor5: the api-ref on master should be the same for newton - where there are functional differences they should be called out with notes or microversions | |
| 21:51:13 | mriedem | i.e. the api should be backward compatible | |
| 21:51:27 | brandor5 | mriedem: oh cool, thanks... any idea on the error I'm seeing? | |
| 21:51:38 | brandor5 | especially that it works when I use the command line client | |
| 21:52:18 | mriedem | can't confirm a resize on a stopped vm in newton https://github.com/openstack/nova/blob/newton-eol/nova/compute/api.py#L2924 | |
| 21:52:38 | mriedem | nor master https://github.com/openstack/nova/blob/master/nova/compute/api.py#L3489 | |
| 21:53:19 | brandor5 | hmm that's weird because `nova resize-confirm <instance id>` definitely works | |
| 21:53:32 | mriedem | works works? or just doesn't say it failed? | |
| 21:53:38 | brandor5 | works works | |
| 21:53:40 | mriedem | which version of novaclient? | |
| 21:53:56 | brandor5 | 10.1.0 | |
| 21:54:29 | brandor5 | and when I run nova in debug I've verified that I'm running the same 'curl' that novaclient is running | |
| 21:55:05 | mriedem | no magic there https://github.com/openstack/python-novaclient/blob/10.1.0/novaclient/v2/servers.py#L1533 | |
| 21:55:44 | mriedem | can you show the server status before doing each (cli and curl) to verify? | |
| 21:56:10 | brandor5 | yeah, I'm doing that... I have a watch running `openstack server show <instance_id>` | |
| 21:56:29 | brandor5 | if I try to hit the api directly I get a 409 | |
| 21:56:36 | mriedem | so you have some script or something that's just auto-confirming a resize as soon as the instance status is VERIFY_RESIZE? | |
| 21:56:37 | brandor5 | if I use novaclient it works | |
| 21:56:44 | brandor5 | correct | |
| 21:56:56 | mriedem | there is a config option for auto-confirming migrations | |
| 21:56:58 | mriedem | .. | |
| 21:57:33 | brandor5 | yeah, that's across the board and the docs say it's not recommended... my script is just for putting a compute into 'maintenance' mode | |
| 21:58:22 | brandor5 | It's actually ansible playbook that sets maintenance mode, checks for errored instances, manually moves shutoff instances, and then blasts the active instances' | |
| 21:59:11 | brandor5 | unfortunately right now I can't use the command line clients because ansible tower doesn't have them installed... (that's a ticket i have open with redhat) | |
| 21:59:21 | mriedem | gd red hat | |
| 21:59:31 | mriedem | i can't see anything that would be a difference between the client and straight curl | |
| 21:59:32 | brandor5 | haha | |
| 21:59:46 | brandor5 | i'll keep poking then... double check my headers and whatnot | |
| 21:59:55 | brandor5 | thanks for the help | |
| 22:00:09 | mriedem | are you polling on the 'status' field in the server show response or something like vm_state? | |
| 22:01:08 | brandor5 | https://pastebin.com/ijVe0J42 | |
| 22:01:31 | melwitt | mriedem: what's the trick to bfv with more than one --block-device? I keep getting ERROR state saying 'no image supplied' even though the first one I give is bootindex=0 with source=image | |
| 22:02:06 | mriedem | brandor5: that looks ok | |
| 22:02:35 | mriedem | melwitt: are you trying to attach data volumes or have nova create the volumes? | |
| 22:02:54 | mriedem | it's probably easiest to just boot and attach 2 data volumes (so not boot_index=0) | |
| 22:03:08 | melwitt | mriedem: I'm consistently trying to have nova create the boot volume, and attach a non-bootable volume I created in cinder ahead | |
| 22:03:09 | mriedem | i.e. pre-existing volumes | |
| 22:03:27 | mriedem | what is your source_type and destination_type? | |
| 22:04:07 | melwitt | this was my latest attempt http://paste.openstack.org/show/737169/ | |
| 22:04:32 | mriedem | --block-device source=image,id=d7b0d7cb-1373-456d-bcec-29fbec2f84e1,dest=volume,size=1,shutdown=preserve,bootindex=0 | |
| 22:04:35 | mriedem | is that id an image id? | |
| 22:04:45 | melwitt | yes | |
| 22:04:51 | mriedem | --block-device source=volume,id=33550efe-6a7b-4956-a7e0-5bd50004ec30,dest=volume,size=1,shutdown=preserve | |
| 22:04:54 | mriedem | and that id is a volume id? | |
| 22:04:57 | melwitt | and that one is a volume id | |
| 22:05:13 | mriedem | you don't need to specify size on the latter, but nova should ignore that | |
| 22:05:36 | melwitt | I think it can be done but I don't know how. I think I've seen launchpad bug reports where people were booting with multiple volumes | |
| 22:06:09 | mriedem | where are you seeing the "no image supplied"? | |
| 22:06:27 | melwitt | in the nova show fault field | |
| 22:06:32 | mriedem | http://codesearch.openstack.org/?q=no%20image%20supplied&i=nope&files=&repos= | |
| 22:06:40 | mriedem | that's not in the code that i can see | |
| 22:06:43 | mriedem | besides the show response | |
| 22:06:48 | mriedem | which is normal | |
| 22:06:53 | mriedem | paste your fault | |
| 22:07:40 | melwitt | http://paste.openstack.org/show/737170/ | |
| 22:07:56 | melwitt | oh sorry | |
| 22:07:57 | melwitt | dammmit | |
| 22:08:05 | melwitt | that was the image field | |
| 22:08:34 | Kevin_Zheng | mriedem: just shelve the vm and all the volume will be in reserved status and cannot be detached | |
| 22:08:36 | mriedem | yeah that's normal | |
