| 16:44:56 | sean-k-mooney | e.g. ovs was using the PF | |
| 16:45:27 | spatel | i will try if i can setup bonding with PF then it would be great | |
| 16:45:54 | spatel | i can protect mgmt traffic but still i will loose dataplan | |
| 16:46:18 | sean-k-mooney | anyway my 1st concern with https://ibb.co/j9kgUK would be that while the datapane woudl remain up on half the node that same half would no lonbger be manageable | |
| 16:47:41 | sean-k-mooney | personally if i could not have a ha manament plane i would put the manament and datapane for my hosts to the same TOR | |
| 16:48:42 | spatel | hmm! ok that also make sense | |
| 16:48:48 | sean-k-mooney | provide you deploy your app to both TORs you will still have half your applications service coustomers but you wil be able to also mange those hosts | |
| 16:48:53 | spatel | data + mgmt on same TOR | |
| 16:49:27 | spatel | If we loose mgmt for few hour i don't think its going to be a big deal.. | |
| 16:49:54 | spatel | these compute nodes are going to run only 1 or 2 instance ( because they are CPU hungry ) | |
| 16:50:17 | sean-k-mooney | well it depens on your useage model. with the split deployemnt you were goning tohave that anyway right since you did not have manamnet ha | |
| 16:50:38 | spatel | Here i am just trying to minimize failure (50%) | |
| 16:51:15 | spatel | i have good remote hand in datacenter and they will replace TOR within 1 hour :) | |
| 16:51:59 | openstackgerrit | Stephen Finucane proposed openstack/nova master: Fix nits in choices documentation https://review.openstack.org/608310 | |
| 16:52:06 | spatel | my main question was if i split server between two AZ then how i can automate instance build so they spread our between A | |
| 16:52:06 | finucannot | fried_rice: ^ | |
| 16:52:08 | spatel | AZ | |
| 16:52:56 | sean-k-mooney | :) well just one other note. if you do end up with ovs-dpdk instead of sriov in that case you would be better just bonding eno1 and eno2 and then using ovs to deivde up the bandwith betwwen manament and teant use. | |
| 16:53:17 | sean-k-mooney | am waht you are asking for is how can i express an antiafinity policy | |
| 16:53:25 | spatel | currently i have script which i manually specify vm-1 go to AZ-1 and vm-2 go to AZ-2 (I am doing by hand ) | |
| 16:54:07 | sean-k-mooney | SteelyDan: ^ we do not have a way to do AZ anti afinity with server groups correct | |
| 16:54:14 | spatel | DPDK is next month todo list :) | |
| 16:54:50 | SteelyDan | sean-k-mooney: I don't even understand those words | |
| 16:55:28 | spatel | I am reading this line from one of openstack doc: The Nova scheduler provides filters that you can use to ensure that OpenStack instances are automatically placed on the same host (affinity) or separate hosts (anti-affinity). | |
| 16:55:38 | sean-k-mooney | SteelyDan: spatel is trying to desing a layout that will allow https://ibb.co/j9kgUK one of the two tors to fail and have openstack loadbalnce vms across them | |
| 16:55:58 | SteelyDan | spatel: that sentence means you can say "put this instance on the same host as this other instance" | |
| 16:56:51 | spatel | e.g - if i tell openstack build 50 instance then it will load 25 on TOR1 server and 25 in TOR2 server | |
| 16:57:35 | SteelyDan | spatel: the doc line you quoted above is purely about affinity between instances, not about affinity or load balancing between two hosts | |
| 16:57:47 | SteelyDan | I don't think we have any way to do that with the existing set of filters, no. | |
| 16:57:52 | spatel | oh! | |
| 16:57:56 | sean-k-mooney | SteelyDan: we had been discussing using AZ to model the network falut domain(TOR) | |
| 16:58:42 | sean-k-mooney | spatel: you might be able to do this with heat. on top of nova | |
| 16:59:10 | sean-k-mooney | spatel: there is one other way to do it which is to use neutron physnets | |
| 16:59:15 | SteelyDan | sean-k-mooney: if nova can't represent this, I'm not sure how you could get heat to do it for you | |
| 16:59:56 | spatel | hmm! i think time to exploration | |
| 16:59:58 | sean-k-mooney | SteelyDan: i was specalting that you may be able to tell heat to spit this request between AZ a and AZ b | |
| 17:00:30 | SteelyDan | obviously if you want to hardcode alternating boxes in the rack to two different AZs and then boot your instances into AZs with your own spread then you can do this | |
| 17:00:37 | SteelyDan | which is all heat could do | |
| 17:00:54 | SteelyDan | but what I mean is, I don't see a way to specify this generically to nova with existing stuff | |
| 17:01:05 | spatel | we can do that by script also right? script will take count and divide them by number of AZ and feed them to nova boot | |
| 17:01:14 | SteelyDan | sure | |
| 17:01:35 | sean-k-mooney | spatel: yep | |
| 17:01:55 | sean-k-mooney | the othere way to model this is via neutron physnets | |
| 17:01:58 | spatel | or write more smart script will will collect data from AZ and then compare which AZ has more room to handle more instance | |
| 17:02:18 | sean-k-mooney | on all the hosts connected to tor1 lable the physnet as top1 | |
| 17:02:26 | sean-k-mooney | and on the others tor2 | |
| 17:02:30 | spatel | can you explain about neutron physnets? | |
| 17:02:44 | spatel | oh!! i know what you saying | |
| 17:03:17 | sean-k-mooney | when using VLAN or Flat netwroks in neutron they are assocated with a physica network or physnet in neutron | |
| 17:03:43 | spatel | hmm! | |
| 17:03:57 | sean-k-mooney | so if you have 2 networks and 2 physnets you can have one AZ and then booth half your vms with network 1 and half with network 2 | |
| 17:04:30 | sean-k-mooney | spatel: that wouls more expcltly model what your actuly doing | |
| 17:04:55 | spatel | never thought about that but look like need to explore, i will try to run some test and see how it work out | |
| 17:04:57 | sean-k-mooney | spatel: it has littel other advanates however over using AZs and still would require your script | |
| 17:05:31 | spatel | i think short term hack is script | |
| 17:05:47 | spatel | but i will go dipper | |
| 17:05:51 | spatel | I think this was really good discussion, let me explore all option and find best fit. | |
| 17:06:10 | spatel | sean-k-mooney: SteelyDan thank you so much for your input..! | |
| 17:06:44 | sean-k-mooney | spatel: sure thing. am fyi while i have ran some devclouds and worked on openstack for quite a while there are also some oepratros in irc that can share there expreicnes | |
| 17:07:28 | spatel | i will find them out soon :) | |
| 17:07:29 | sean-k-mooney | spatel: maybe reach out to mnaser too im sure he can share his experices | |
| 17:07:41 | spatel | this is just beginning i have more to learn | |
| 17:08:14 | spatel | let me write down his name :) | |
| 17:08:28 | spatel | did you work on Octivia LB ? | |
| 17:08:30 | sean-k-mooney | spatel: well if you havent check it out before there is a lot of greate matial on the openstack foundation youtube channel. but if i can help you know where to find me | |
| 17:09:12 | sean-k-mooney | spatel: Octivia no unfortunetly not. | |
| 17:09:14 | spatel | i think i know where to go for any kind of help... (find sean-k-mooney) | |
| 17:09:32 | spatel | no worry i may soon need ELB for cloud | |
| 17:09:53 | spatel | we have lots of F5 but i need ELB so i don't need to worry about capacity | |
| 17:10:28 | spatel | BRB my lunch is ready.. | |

| 18:21:34 | Blotis_ | Is it possible from withing the CLI to figure out which VM's are currently using a particular group? | |
| 18:22:45 | Blotis_ | if I want to remove a security group that is currently being used by a vm, I have to remove that security group from that instance first...what if I have too many instances? is there a quick solution? | |
