| coli | kiall: have you seen my comment about your ec2_dmz_host in nova.conf from your scripts ? | 01:02 |
| Kiall | nope must have been lost in the netsplits! | 01:03 |
| coli | you should set ec2_dmz_host to ip of a compute host and not to a ip of a controller, otherwise instance when contacting nova-api on the controler is not going to get the metadata (when compute and controler on different host) | 01:04 |
| coli | you have nova-api on your computes but they are not used by instanaces | 01:04 |
| Kiall | that doesnt sound right, since there could be 1000's of compute hosts? | 01:04 |
| coli | and each compute host has nova-api which directly talks to mysql | 01:05 |
| coli | just to show you what is happening: | 01:05 |
| *** miclorb_ has quit IRC | 01:05 | |
| coli | 1) instance when starting tries to contact 169.254.169.254 | 01:06 |
| coli | 2) PREROUTING is DNAT'ing that request to controler ip and port 8773 | 01:06 |
| coli | 3) routing takes place to go out of eth0 to controler host | 01:06 |
| coli | 4) as this is remote host POSTROUTING takes place which is SNAT'ing the source to ip of compute host | 01:07 |
| coli | 5) nova-api receives the request, and is looking up metadata for an instance based on the source ip address (which is not that of an instance but of an compute host) and doesn't find any | 01:08 |
| *** blur has quit IRC | 01:08 | |
| coli | if you set ec2_dmz_host to compues ip, then it contacts local nova-api and as it's local interface then no POSTROUTING takes place and source address is not nat'ed | 01:09 |
| coli | ufff... | 01:09 |
| *** woleium has quit IRC | 01:09 | |
| Kiall | Ah yea.. I've actually got that in my 2nd+ node's nova.conf already .. Looks like its missing from the scripts! | 01:10 |
| *** RicardoSSP has quit IRC | 01:11 | |
| coli | overall your scripts are very nice and helped us a lot in undrestanding what is happening. thank you. | 01:11 |
| Kiall | no problem :) | 01:12 |
| Kiall | BTW - In your searching, you didnt find a way to avoid nova-api on each compute node did you? ;) | 01:12 |
| * Kiall keeps typing into the wrong keyboard | 01:13 | |
| *** n8 has joined #openstack | 01:13 | |
| Kiall | (have a second PC at my desk for a few mins) | 01:13 |
| *** n8 is now known as Guest51757 | 01:14 | |
| coli | no in your solution, as you are using eth0 (public interface) to communicate with the controller, what causes all communication to be snat'ed | 01:14 |
| Kiall | Humm, I wasnt aware any of the nova rules we're tied to a specific interface | 01:15 |
| coli | if you had separate network just to communicate with conroler then you can do it using dmz_cidr parameter, what would cause to accept the packet before it's snated and controler is going to know where to send reply to the privae ip address of the instance | 01:15 |
| coli | "tied to specific interface" ? I didn't get that | 01:16 |
| Kiall | as in, none of the iptables rules have "-i <some interface>" | 01:16 |
| coli | however wormman is running nova-api on each compute host as well as he has discovered performance issues when using just one nova-api | 01:17 |
| coli | kiall: none of them have -i and we are not tied | 01:17 |
| Kiall | WormMan: noticed the issue with launching 200 instances at the same time :) | 01:17 |
| Kiall | s/:// | 01:17 |
| coli | kiall we hope to get there... don't we ? ;-) | 01:18 |
| Kiall | Just digging through the code, and yea.. I'm setting dmz_cidr way off | 01:19 |
| coli | let me thnik. | 01:19 |
| coli | no ideas right now how to do it otherwise in your setup | 01:20 |
| cloudgeek | going for exam | 01:21 |
| coli | in my opinnion the main architectural/desing flaw is that nova-api searches for metadata based on source ip address. or there is something what i'm missing | 01:21 |
| cloudgeek | study whole night bye openstack | 01:21 |
| Kiall | yea, eth1 should get an IP in some dmz_cidr, and that IP should be used in the ec2_dmz_host setting .. (Right now, I force my eth1's up without an IP) | 01:21 |
| coli | cloudgeek goodluck | 01:21 |
| Kiall | good luck | 01:21 |
| cloudgeek | coli:Kiall:thanks | 01:21 |
| coli | kiall you don't need that, as nova-api listens on all interfaces you can set ec2_dmz_host to public ip of the compute host | 01:22 |
| *** livemoon has joined #openstack | 01:23 | |
| Kiall | sure, and set dmz_cidr to the controllers public subnet, but my floating IPs are in the same subnet.. so setting dmz_cidr to the public subnet will end badly | 01:23 |
| coli | you don't need to set dmz_cidr in my opinnion as the ec2_dmz_host is local so no POSTROUTING is happening and no source address rewriting (snat) | 01:24 |
| coli | all calls are going to be to local nova-api which in trun will talk to mysql directly | 01:24 |
| Kiall | Ah, I'm talking about when using 1 nova-api instance (or, dedicated nova-api servers) rather than co-locating it on every compute node | 01:24 |
| coli | then you need to do it | 01:25 |
| coli | but remember that packets going to controler will have source address of an instance (its fixed ip) so your controler needs to know how to route those | 01:25 |
| Kiall | 1 nova-api per nova-compute is not really necessary IMO, even for larger deployments.. The added connections overhead to MySQL would be a PITA vs a pool of nova-api servers... | 01:26 |
| coli | your setup is not designed for large deplyments as it can only support up to approx 4080 tenants | 01:26 |
| coli | you are using vlan network mode | 01:26 |
| Kiall | Yea - thats a hard limit alright ;) | 01:27 |
| coli | i'm just working out how to use flatDHCP instead in order to get rid of vlan's and have one large network on the fixed_ip side. | 01:27 |
| *** pradeep has quit IRC | 01:28 | |
| Kiall | coli: feel free to send a pull request with any changes to the scripts, I'll try and merge them in as an option... People keep asking about flat DHCP ;) | 01:28 |
| coli | I have no idea what a pull request is :-) it's my first time I'm using git :-( | 01:29 |
| Kiall | Github has good git guides ;) | 01:29 |
| coli | when I get somewhere reasonably working I will let you know and send you my findings :-) | 01:29 |
| Kiall | Anyway - I've like another 200 firewall rules to check before heading home :( | 01:29 |
| coli | get focused then | 01:30 |
| troya | hi all | 01:30 |
| coli | hi | 01:31 |
| troya | coli, do you have more experience use Flatdhcp ? | 01:33 |
| coli | troya: not yet, just starting | 01:33 |
| troya | i have some problem with my instances now, i cannot ping and accessing ssh into.whereas i have configure security rule to allowing ssh and icmp | 01:35 |
| coli | did you configure the policies through dashboard ? | 01:36 |
| *** woleium has joined #openstack | 01:36 | |
| coli | did you assign floating ip to the instance ? | 01:36 |
| Kiall | set interface openvpn vtun3 mode site-to-site | 01:36 |
| Kiall | dooh | 01:36 |
| troya | i don't install dashboard | 01:38 |
| coli | ok | 01:38 |
| coli | did you have a look at iptables and its counters ? | 01:38 |
| troya | and i haven't configure float ip to isntances | 01:38 |
| troya | i think i haven't configure any rules on ip tables | 01:39 |

| zykes- | reidrac: we're wanting to do | 09:15 |
| zykes- | 2 nodes pr location | 09:15 |
| zykes- | with 4 zones | 09:15 |
| zykes- | does that sound reasonable ? | 09:15 |
| reidrac | 2 nodes per location? | 09:15 |
| zykes- | 2 servers | 09:15 |
| zykes- | for replication | 09:16 |
| zykes- | 2 in each DC | 09:16 |
| zykes- | bad idea or ? | 09:16 |
| reidrac | are you building a cluster split in several DC? | 09:16 |
| reidrac | if you have a very good link between them, it shouldn't be a problem | 09:16 |
| zykes- | do you need 4 nodes in a seperate cluster ? | 09:16 |
| *** mu574n9 has quit IRC | 09:17 | |
| reidrac | the zone is supposed to be the biggest point of failure you're going to deal with | 09:17 |
| zykes- | so you can have like 2 zones in one dc and 2 in another ? | 09:18 |
| reidrac | ie. a zone can be a server, each server with different power bar in a different rack | 09:18 |
| reidrac | if you do that, and you lose 1 dc, you're out with 2 zones missing | 09:18 |
| zykes- | so basically screwed ? | 09:18 |
| reidrac | the zones are used for replication | 09:19 |
| zykes- | yeah | 09:19 |
| zykes- | but like | 09:19 |
| reidrac | you're guaranteed to have data replicated into different zones | 09:19 |
| zykes- | we have 1 "data" room here in the office building and also a colocation datacenter | 09:19 |
| zykes- | we are looking at having 2 servers (2 zones) pr location | 09:19 |
| zykes- | would that be doable ? | 09:20 |
| reidrac | as long as you have good connection between locations (bandwidth is vital!), yep | 09:20 |
| zykes- | what happens if i loose the connection in between then for say 3-5 hours ? | 09:20 |
| reidrac | you loose 2 zones in the cluster | 09:20 |
| zykes- | but is the "replicas" still fine ? | 09:21 |
| zykes- | or will i suffer from data loss | 09:21 |
| reidrac | if you're using 4 zones with 3 replicas and lose 2 zones, you can't operate | 09:21 |
| zykes- | :/ | 09:21 |
| zykes- | so no swift for uss then | 09:21 |
| reidrac | I wouldn't split the zones in different DCs at first | 09:22 |
| tudor | anybody have experience setting up live migration? i set it up as per documentation and get a "TRACE: AMQPConnectionException: (503, u"COMMAND_INVALID - second 'channel.open' seen", (20, 10), 'Channel.open') | 09:22 |
| reidrac | it's an expensive design choice and there's not big benefit IMHO | 09:22 |
| *** wi3dzma has joined #openstack | 09:23 | |
| zykes- | reidrac: wouldn't you need that for off site distasters ? | 09:23 |
| reidrac | I think that if you lose a DC, something that SHOULD be very unlikely, it's fine your storage is unavailable ;) | 09:23 |
| reidrac | zone = server it's usually a good idea, because hw can fail, and losing 1 server it's not impossible | 09:24 |
| reidrac | but using different DCs as zones, that's a completely different level :D | 09:25 |
| zykes- | reidrac: that's one thing, but what about having other copies of the data ? | 09:25 |
| zykes- | i mean off site from the datacenter | 09:25 |
| reidrac | you can have backups offsite | 09:25 |
| zykes- | using swift or ? | 09:26 |
| reidrac | as a recovery plan | 09:26 |
| *** nacx has joined #openstack | 09:26 | |
| reidrac | not using swift | 09:26 |
| zykes- | that's kind of the deal, we're only within 8 km from the DC | 09:26 |
| zykes- | so it's simple enough except from bw to replicate over the link | 09:26 |
| reidrac | what are we talking about? | 09:26 |
| reidrac | what kind of disaster? | 09:27 |
| zykes- | reidrac: say a fire within the dc ? | 09:27 |
| zykes- | has happened before :) | 09:27 |
| reidrac | fire on the DC or it's just a matter of availability | 09:27 |
| reidrac | ah, I see | 09:27 |
| reidrac | I would recommend looking for a different DC | 09:27 |

| omsynge | sorry tudor not that far, and assume you need a shared file store fro migration, if you do I think its not applicable to the size I want to scale our services too, but understand for smaller sites this may be practical | 13:59 |

| _rfz | praefect, how do you configure auto_assign of floating addresses? | 14:49 |
| praefect | coli: I'll look it up, it is a single line to change in network/manager.py but it makes a lot a difference when you use auto assign of floating | 14:49 |

| _rfz | have you got --force_dhcp_release=True on all your nova.conf? | 14:53 |
| _rfz | coli, are you using kiall's repo? | 14:54 |
| praefect | coli: https://review.openstack.org/#patch,sidebyside,1328,3,nova/network/manager.py this is what I changed, I'm using rpm packages for nova so our code may be different, for example of the 2 changes listed in this URL, one was already in place in my code, not the other.. I applied this and auto_assign works flawlessly | 14:55 |
| coli | _rfz: it's not a repo, but started with his scripts. | 14:55 |
| *** sdake has joined #openstack | 14:55 | |
| _rfz | so how did you install nova-compute? | 14:55 |
| coli | _rfz: corrected his ec2_dmz_host setting as well | 14:56 |
| coli | ./nova-compute.sh | 14:56 |
| praefect | _rfz: since I'm on centos, I don't have access to the dhcp_relase binary which you guys get access to in ubuntu, hence I just generate errors currently when trying to force dhcp release of fixed ip, but to answer your question, this error only appears on my network node so you just need this switch on your controller(network) I guess | 14:56 |
| coli | and that is all | 14:56 |
| coli | remember to change ec2_dmz_host to a public ip of your compute host | 14:56 |
| praefect | all works well without dhcp_release, the force-dhcp-release is just a way to speed things up, upon termination the fixed ip will be release automatically | 14:57 |
| praefect | if not there is a timeout and the fixed ip will be cleaned eventually | 14:57 |
| _rfz | praefect, what guide did you use to install openstack on centos? | 14:57 |
| coli | praefect: do you have nova-network on a controler or on computes ? | 14:57 |
| _rfz | you need them on both | 14:57 |
| praefect | _rfz: ALL OF THEM! there is not much but start with the official one (search RHEL on openstack.org) | 14:58 |
| _rfz | praefect, hehe | 14:58 |
| praefect | coli: I have nova-network only on my controller, (I'm not using multi_host) | 14:58 |
| troya | hi all | 14:59 |
| coli | ok | 14:59 |
| praefect | coli: I think you need 2 NICs on all compute nodes if you want them to be network controllers (and use floating ips) | 14:59 |
| praefect | which I don't | 14:59 |
| coli | praefect: I have three hosts are present, one controler and two computes. each has two nics | 15:00 |
| praefect | I channel everything to my controller (running nova-network) and traffix goes out through its public NIC (floating IP) | 15:00 |
| coli | anybody attending DCD next week ? | 15:00 |
| praefect | coli: then in this setup you could run multi_host=T (when creating your network) this will spawn a nova-network on all nodes and route traffic individually, the goal is that with this setup, if you loose the controller, spawned instances will still have access to the network (internet) | 15:01 |
| coli | praefect: that is how I got it setup right now. | 15:01 |
| praefect | while in my case, if I loose the controller, even if the instances are up they are effectively cut off from the network | 15:01 |

| andyandy_ | do you know if I can have more then one nova-volume ? thanks. | 15:03 |
| praefect | coli: I have 2 clouds here, one with 2 powerful servers (24 cores each), and one cloud with desktops (8 cores xeon)... I'm going to play with zones and scheduling today)... but anyway, my setup is really nice now, no more IP management problems, not more lock file problems (only affecting centOS) | 15:03 |
| praefect | it is not easy to have this working on CentOS, griddynamics did a terrific job and their repo is now better than ever | 15:03 |

| _rfz | Kiall, have you done run stress tests on your openstack environment? | 16:23 |
| Kiall | Nothing major .. noticing any issues? | 16:25 |
| Kiall | WormMan is probably the guy to talk to re stress testing ;) | 16:26 |
| Kiall | I know he's done a fair bit of tuning... | 16:26 |
| _rfz | I've started to run some tests now (creating 100vms) so far it's running okay | 16:27 |
| _rfz | but the dashboard is real sloow | 16:27 |
| Kiall | my default apache config is.. lacking.. | 16:27 |
| Kiall | But, I believe thats an issue with the diablo dash anyway.. | 16:28 |
| Kiall | the essex dashboard seems faster to kme | 16:28 |
| Kiall | me* | 16:28 |
| Kiall | (I've got the essex dash packaged up @ http://launchpad.net/~managedit/+archive/openstack-testing) | 16:28 |
| Kiall | Its (mostly) compatible.. | 16:28 |
| Kiall | and by mostly, I reckon they are just bugs in the essex dash | 16:28 |
| andrewbogott | Hm... is anyone about who can advise me about using devstack with the nova master branch? Or is anyone about who knows about devstack, at all? | 16:32 |

| zefry | None: None | 16:54 |
| zefry | hello anyone | 16:54 |
| Kiall | _rfz: really? only 30? anything interesting in the logs? | 16:55 |
| _rfz | coli, with a script that uses euca-run-instances | 16:55 |
| _rfz | kiall, not much the compute service needed to be restarted a few times | 16:56 |
| Kiall | no errors out of it? it just hung? | 16:56 |
| Kiall | zefry: usually that means your EC2 credentials are incorrect | 16:57 |
| Kiall | are you using keystone or not? | 16:57 |
| coli | _rfz: do you run nova-api on seprate host ? did you do sleep X; between starting instances ? | 16:57 |
| Kiall | zefry: and, how did you install nova? from ubuntu repos? devstack? something else? | 16:58 |
| zefry | i'm install openstack on ubuntu server 11.10 | 16:58 |
| _rfz | coli, I just run nova.api on the controller host, no sleep between creating the instances | 16:58 |
| Kiall | zefry: and the other question re keystone? | 16:59 |
| coli | _rfz: remaind me how many computing hosts ? | 16:59 |
| coli | _rfz: remember that instances use nova-api as well when booting in order to get the metadata. | 17:00 |
| zefry | Kiall: have a solutions?? | 17:00 |
| coli | _rfz: did you try to spread the nova-appi onto compute hosts ? | 17:00 |
| Kiall | zefry..maybe.. if you can answer the questions ;) | 17:00 |
| _rfz | coli, I will try installing nova-api on the compute nodes - and let you know how it goes | 17:01 |
| *** nerens has quit IRC | 17:02 | |
| _rfz | Kiall, no errore just hangs | 17:03 |
| Kiall | _rfz: yea.. the EC2 metadata part of nova-api is being split into a new service in essex i believe.. well, not a new service.. but something you can run a nova-api for just the MD | 17:03 |
| *** dolphm has quit IRC | 17:05 | |
| _rfz | kiall, when I try install nova-api on the compute node I get this error: ImportError: No module named keystone.middleware.ec2_token | 17:06 |
| coli | kiall: it's garbing it from the central mysql so it's still a bottleneck however nova-api middleware is working on the compute hosts. I cannot see the reason for spliting it into a special part just for metadata, however I have seen some other blueprints for essex which don't make any sens from architectural and design point of view (just for interest of some comapnies) | 17:06 |
| Kiall | _rfz: python-keystone is needed to | 17:06 |
| Kiall | too* | 17:06 |
| _rfz | cheers | 17:06 |
| Kiall | if you use keystone, since the API paste references a keystone class for keystone auth | 17:07 |
| cloudgeek | bye all | 17:07 |
| coli | _rfz: you need python-keystone | 17:07 |
