creihtgourneau: With some modifications, perhaps :)02:09
creihtfor swift, it would need more cpu, for example02:09
*** shang has quit IRC02:10
creihtI would also worry about the lack of redundancy02:10
creihtlike for power for example02:10
*** kaz_ has quit IRC02:10
*** sdake has joined #openstack02:10
creihtit also sounds cumbersome to replace drives easily on one02:10
creihtYou can get pretty close to that type of density, with more standard/reliable commodity hardware for not a lot more02:11
creihtfor example02:12
gourneauI saw that on hackernews as well, the drive bays look nice.02:13
*** GeoDud has quit IRC02:13
creihtThey are very nice :)02:13
gourneauSo can swift make a data store out of a pools of disks like those?02:13
creihtthat is what it was designed for02:13
creihtright now we currently run on a more standard 4U with 24 2T drives chassis02:14
gourneauWhat are the types of redundancy?  How easy is it to scale?02:14
creihtgourneau: swift was built on a model similar to S302:14
creihtswift stores 3 redundant copies of each object in 3 separate zones02:15
creihtzones are very abstract, so it could be set up to be 3 different drives, or 3 different racks, each with different power/network etc.02:15
gourneauWhere a zone would be a JBOD chassie?02:15
creihtdepending on how much you want to isolate failure02:15
gourneauOh I see02:16
med_outideally each zone is as isolated as possible from other zones (w/r/t failure modes)02:16
creihteach of our zones are multiple racks of servers that have isolated power/networking/etc.02:16
gourneauHow should the disks be formated?  Do I have to setup raid or LVM or anything fancy?  Does switft just remove the need for those layers ?02:16
gourneauThe file size is 5 gigs right now right ?02:17
creihtwe recommend that each drive be formatted with xfs02:17
med_outno raid (it defeats the purpose)02:17
*** adjohn has quit IRC02:17
gourneauI am bummed my company just dropped over a million on a lame DDN system.02:17
creihtthe max object size is 5 gigs, but you can have larger objects through manifest files that point to multiple chunks of an object02:18
*** med_out is now known as medberry02:18
creihta get on the manifest will serve it as if it was one single file02:18
gourneauHow are the objects accessed?  Are the objects of the file system? Or do I have to go through another interface.02:19
creihtthey are on the filesystem02:19
creihtgourneau: btw:
creihthas a lot of documentation :)02:20
gourneauIf I had a multi terabyte file through a manifest file, would that be a bad idea?02:20
gourneauhah ok, I will check it out :)02:20
gourneauThanks for the info02:20
creihtgourneau: not at all02:20
gourneauAre any of y'all from Texas?  I ran into Dragon at PyTexas last year02:20
gourneau(Dragon of Rackspace)02:20
creihtgourneau: all of the rackspace swift devs are in San Antonio02:21
creihtand, yes, I know Dragon :)02:21
gourneauVery cool :)02:21
gourneauSo what magic sauce is Nebula going to bring to the market ?02:22
* creiht defers to the nebulites :)02:25
gourneauDear Nebulites, we the builders of the nets need petabytes now , we will spend $100,000/petabyte. Thanks!02:26

*** periyeda has quit IRC11:06

siwosug: a-z is not related to project11:11
siwosa-z is a single unit of failure11:11
siwosin cactus you run your cloud via nat. if nat breaks, then you loose access to all your vm-s11:12
siwosso - the network-controller providing nat and compute nodes hidden behind this nat, are a single unit of failure (availability zone)11:12
*** javiF has quit IRC11:12
*** ejat has quit IRC11:13
ugsiwos: nice explanation...that really helps. thanks to both of you11:15
*** worstadmin has quit IRC11:15
siwosyou protect yourself from failures by placing vm-s in different availability zones (for example db master in one, slave in the other)11:15
*** worstadmin has joined #openstack11:17
alexn65I think he asks about what return euca-describe-availability-zones cmd :)11:17
alexn65siwos: you good at swaut?11:18
siwosnot really11:18
siwosnot as good as on compute11:18
siwoseuca-describ-availability-zones returns you a list of availability zones (just as the name implies) ;-)11:19
siwosyou can then use these availability zones in euca-run-instances11:19
alexn65I need some API call from java to swauth - two variants for now - via http and via bash :) Think Http more flexible but cannot curl right URL doesn`t go (swauth for cactus i.e 1.0 version)11:22

siwoswhy do you think there would be 2 upload operations?11:30
siwos20gig is a huge image11:30
siwosremember it will need to be cloned each time you launch an instance of it11:30

alexn65I cannot find where I saw it today - but I really see reason why glance-upload script was written - if you bundle image than register - u can see that two times in /tmp occurs some tarring processes - one when bundling, than one when image status pending(and further) - glance itself download bucket, decode it and upload to glance container11:39
alexn65I`m not scred right now couse it`s still not a project finish line, but will be worse11:39

siwos20gb is the size of vmdk11:46
siwosso it won't necessarily be 20gb11:46
tznsiwos: unless is really 20g full of data11:46
alexn65glance understand zipped images? not glance reaaly,but nova after it11:47
Vadimhi guys11:47
siwoswhen you create image with eucatools it gets gzipped11:48
siwosby default11:48
alexn65heh :) I wonder if one can see df-like for swift and nova or so, just to understand space allocation11:49

kbringardalexn65: sure, only one?14:04
troyalivemoon: i have doing it, i have allow port 8014:05
livemoonkoolhead17 : how do you install nova on 11.10? via apt-install or git ?14:05
troyaeuca-authorize -P tcp -p 80 default  << this is my syntax14:05
kbringardtroya: it's a good idea to allow ICMP so you can do basic network troubleshooting on the instance14:05
koolhead17livemoon: apt-get14:06
troyakbringard: i also use syntax >> have euca-authorize default -P icmp -t -1:-114:06
livemoonkoolhead17 : which ppa?14:06
kbringardtroya: ah, good good, can you ping the instance from your controller?14:06
kbringardvia it's internal IP address?14:06
kbringardalso, what network mode are you using?14:07
alexn65kbringard: :) at least. It`s about packaging - siwos said that images can be in qcow format that first, and second can be gzipped as uec done - couse I upload very large img >20Gb and two times got error after long waiting - it would be great to reuse uec or cloud-init tools somehow14:07
troyaon controller i can access instances via ssh14:07
kbringardalexn65: fair enough, that makes sense… the way I'd been using it was to download a uec image, unzip it and then just use ogler on the images that came out of the zipfile14:08
kbringardI can work on adding a new flag to tell it to use a uec zipfile14:08
koolhead17livemoon: you don`t need to add any PPA on oneiric :D14:08
kbringardso it'll extract the image and stuff itself14:08
livemoontroya : from another machine?14:08
kbringarddo you have ip forwarding enabled on your network controller?14:09
livemoontroya : for example ,a server in the same network as your controller14:09
kbringardnet.ipv4.ip_forward=1 in /etc/sysctl.conf14:09
troyakbringard: do you mean,  i must copy zipfile of credential to other computer ?14:10
kbringardtroya: not credentials… we're just trying to find out where the communication is breaking when attempting to talk to your VM14:10
kbringardyou can get to it from the controller, so if we move away one hop, can you still get to it?14:11
troyalivemoon: i can access only on controller, but on the other computer i can't , whereas client is on other computer14:11
livemoonwhich linux do you use?14:11
livemoon# sysctl -a14:12
alexn65kbringard: I think u don`t understand :) - I cannot use glance-upload for image larger than XGb - but uec can bundle it - gzip and split on chunks. It just do also crypt them - that not needed for glance14:12
livemoonI think linux iptables is hard to me. I only can use pf firewall.14:12
kbringardoh… really?14:12

livemoontroya: you can email to me if you have some question14:15
troyalivemoon:what's your email address ? may be via email will be clerly14:15
livemoonkoolhead17: what is that software?14:17
kbringardlivemoon: it's a ruby script for uploading images directly into glance, setting meta-data, automatically linking kernels and ramdisks, etc14:18
koolhead17livemoon: image uploader on openstack :)14:18
livemoonwhy not use glance command directly?14:18
koolhead17kbringard: you ruby fanboi !! :D14:18
kbringardlivemoon: you can if you want14:19
kbringardbut ogler uses an external library called ogle14:19
kbringardso you don't have to have glance installed on the machine you're uploading from14:19
kbringardit sets all the headers and interacts with glance directly14:19
*** jfluhmann has joined #openstack14:19
*** MarcinJ123_PL has quit IRC14:20
kbringardplus, it links the kernel and the ramdisk automatically, so you have a default kernel and ramdisk when you go to launch it14:20
livemoonI see14:20
kbringardit's just an alternative way of doing it14:20
kbringardI personally find it easier, but as you like :-)14:21
alexn65kbringard: off question - give some advice for API to use glance/nova/swift/swauth? is there any java libs don`t you know?14:21
alexn65I like becouse of bash :)))14:21
livemooncan it upload img format image?14:21
kbringardalexn65: sorry, I don't… I actually wrote my own for Ruby (ogle) and hugs (the HTTP library wrapper) was written by dewey, the guy who wrote that blog14:22
kbringardalexn65: I wrote a bash script that's a wrapper around glance-upload14:22
kbringardif that's more useful14:22
kbringardit requires that you have glance installed on the machine you're uploading from14:23
kbringardbut it does more or less the same thing14:23
alexn65I do use this one :) not ruby14:23
kbringardlike I said, it'd just a wrapper around glance-upload, which is itself just a wrapper around glance upload14:24
alexn65livemoon: It upload img, right. for glance you can upload anything - but make sure you can use them after14:24
alexn65:) %)14:24
kbringardlivemoon: yea, what alexn65 said. it just takes whatever datastream you give it and sends it to glance14:25

*** nerdstein has left #openstack14:30
kbringardthat just lets you force the keys, instead of letting nova generate them14:30

praefectFabriceB: I'm using a second interface as the flat_interface, no ip just used as a phy for the bridge... if it helps15:24
RaziqueFabriceB: how could it be an ARP issue ?15:24
FabriceByou're doing ping, so you're doing IP15:24
FabriceBthe arp layer is the mapping between mac address and ip address15:25
praefectalexn65: I've been working on openstack for a 1 month now (new job), it takes patience... on CentOS at least it really does15:25
FabriceBand an arp cache has a ttl about 20 minutes15:25
praefectoooooooh I like that FabriceB!15:25
Raziquemaybe from the instance you could run an arpping ?15:25
*** worstadmin has joined #openstack15:26
Raziqueto the gateway for instance15:26
praefectI run arp and it seems to output all known arp, so I'll save that and compare it later15:26
Raziqueif we suppose the messy arpcache is that one15:26
Raziquemmm FabriceB there is something I don't get :D15:27
FabriceByes ?15:28
Raziqueactually nova-networks runs iptables rules while it holds all the "public ips"15:28
Raziqueso the aro address don't change on the instance, and the outside network only sees ARP address from the cloud controller15:28
FabriceBnot on flat interfaces15:29
FabriceBit's a bridget network15:29
Raziqueohhh yes, you are right15:29
Raziquemy bad15:29
Raziqueok so from the instance, you could run this arping -c 1 -S $public_ip $gateway15:30
Raziquefor instance arping -c 1 -S
praefectI'm lost in all this network stuff, damn there is a lot going on!  For example I am still forced to use an unconfigured if (eth1) to bridge and I don't know why I can't get it to work with a single if, do you guys have compute-nodes with single NIC?15:30

Raziquepraefect: exactly15:40
Raziquewhile the server which runs nova-network will act as a gateway15:40
Raziquebridge means the compute-node becomes transparent, and let pass every packet, even if they are not destinated to it15:41
Raziquethat's why a bridge is necessary in a flatDHCP mode15:41
Raziquebut, as FabriceB said, you could then encounter arp issues15:41

crussellhowever, in looking around my lo doesn't have a pipa like 169 for the rule to work right16:59
crussellThe authorize has been done16:59

crussellthe only possibilty could be that i don't put a default gateway on br10017:41
crusselland instead add one specific route for the subnet to the router17:42
WormManjusr wait until you move to split horizon routing :)17:42
alexn65last is unlikely17:42
WormManoh, I remember some glitch like that with routing for the meta-data service17:42
WormManit may have just been an unallocated ip17:43

kbringardwhat do you have set for your flat_interface and public_interface?17:47
kbringardin your nova.conf17:47
crusselli have --public_interface=eth2 ( my 10.0.64.x)17:48
crusselland my nova.conf is absent --flat_interface17:48
kbringardsorry, I may have missed this earlier, what network mode are you using ?17:48
kbringardoooo, OK, why not FlatDHCP?17:49
crussellno, i have a dhcp server on this network and can't risk it..17:49
kbringardah, OK17:49
crussellwell ( i suppose i could cut it off ) i really don't need it17:49
crusselli just have it to aid in server provisioning.17:49
kbringardsorry, you may have already been over this… have you created the IPtables forwarding rule for the 169 address manually?17:50
crussellI see that FlatDhcp adds all the iptables stuff for you17:50
kbringardyea, that's why I was asking17:50
crussellkbringard: yes but check this17:50
WormMan(so, did you add the address?)17:50
kbringardI've never used Flat manager and I have limited experience with FlatDHCP, so I'm not 100% sure what rules need to be added17:50
crussell1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN17:51
alexn65you see that in iptables-save log17:51
crussellthe lo - is missing the address17:51
crussellwhich i think is the root of all my problems17:51
WormMancrussell: I believe Flat won't do anything, so you need to add that by hand17:51
alexn65ip addr|grep 169.254 missing?17:51
crussellyes, missing! =/17:52
crusselland i didn't have to add it last time i made this work...17:52

alexn65on loopback17:55
Kiallhumm .. how does one add a user to an exisiting project?17:55

Kiallboostrap: you can get OpenStack running on a single server, so .. i'd say a *bare min* is about 2G ram and a VT enabled dual core processor..18:44
TheOspreyok, in that case both distros will just work18:44
Kiallyou wont get many instances running on that ..18:45

koolhead17kbringard: yes i got it20:35
kbringardbecause they inherently get all roles in all projects20:35
koolhead17ooh ok20:35
kbringardthen, when I create a new project20:35
kbringardnova-manage project create —project="someproject" —user="bob"20:36

kbringardkoolhead17: I have another install that I run trunk on20:47
kbringardbut I do it from the ppa trunk packages, not source20:47
koolhead17hey gnu111. you missed awesome conversation with kbringard on rbac20:47
koolhead17kbringard: okey. one more question20:48
gnu111sorry. had to run to a meeting.20:48
koolhead17then you create zipfile which has credential and novarc20:48
koolhead17gnu111: :)20:49
kbringardyea, nova-manage project zipfile20:49
gnu111koolhead17: thanks!20:50
kbringardnova-manage project zipfile —project=someproject —user=bob20:50
kbringardthat'll save a file called nova.zip20:50
koolhead17kbringard: do u need to change access credentials in it as by defualts it comes like "username:project"20:50
kbringardwhen you unzip it it'll have a file called novarc, which you should be able to just source (. novarc) and then start running euca-* commands20:50

kbringardnow, I do everything with the ec2 api, so I can't couch for the openstack API20:51
kbringardit should work, I just don't know the commands off the top of my head20:51
kbringardthe access key and secret key stay the same20:51
koolhead17kbringard: in my case i have to replace the secret key with the one that got created during creating the user20:51
kbringardfrom project to project, once you have the novarc you can generate a new zipfile for each project or you can just change the project name after the : in the access key20:51
kbringardif you've created the user and then generate the zipfile, all the right info should be in there20:52

gnu111koolhead17: I am still running Cactus. This worked for me:
KiallEverything else works for me, bar that20:53
koolhead17gnu111: ooh. we are all on diablo and am having some issues there :(20:53
gnu111I can't get diablo work with RHEL :(20:54
koolhead17kbringard: even i create per project and per user zipfile to source him for running euca commands20:54
gnu111maybe have to try installing it from source.20:54

gnu111The sysadmin role allows uploading kernels. I need to find a way to not allow users to upload and register kernel. I want them to use an existing kernel with their own image. is that possible?20:57
Kiallkbringard: damn -_- thats with trunk right?20:57
kbringardthat's with the diablo release20:58
Kiallsame here, yet that command is failing for me20:58
kbringardI'd remove the user and try again20:58
kbringardor try again with a new user20:58
kbringardI really don't know, but I'd say something has to be hosed, because it should be working :-)20:59
KiallJust cloned the nova diablo branch, killed the nova-api from ubuntu's packages, and started one from the clone...20:59
Kiallit works now -_-20:59
kbringardthere you go :-)20:59
koolhead17Kiall: i need the way too.20:59
Kiallkoolhead17: i just cloned from the github repo and ran the API server from the clone (using the original flags+db+etc etc)21:00
koolhead17Kiall: you mean nova shipped with oneiric has some issue which is resulting us in this problem?21:00
Kiallpossibly, not 100% sure whats going on21:01
koolhead17Kiall: exact url needed :P21:01 ;)21:01
koolhead17but kbringard your using it directly from oneiric repository isn`t it21:02
kbringardI'm not using the oneiric repo21:02
* koolhead17 is superconfused21:02
kbringardI use the launchpad PPA repos21:02
kbringardI've never used an official ubuntu repo for openstack21:02

koolhead17kbringard: please pass me the link i will try the same tommorow once am in office. to execute as you mentioned21:03
kbringardapt-get -y install python-software-properties && add-apt-repository ppa:nova-core/trunk21:03
kbringardapt-get -y update21:03
koolhead17Kiall: kbringard you don`t have to mention flag --use-deprecated-auth=true  in your nova.conf ?21:03
kbringardkoolhead17: that template is slightly old21:04
kbringardI use deprecated auth21:04
kbringardand I use the correct pipeline in the api-paste.ini21:04
koolhead17aah you add that handle too in nova.conf21:04
koolhead17i have not added these 2 there21:04

allan_I want to demonstrate cloud computing, what is the minimum requirement connection for my ISP?23:50
allan_from my ISP*23:51
allan_my LAN is using 1000Mbps23:53
Kiallwell .. nothing really .. you dont even need an internet connection to run openstack23:54
Kiallthe instances you run might want internet access .. but that entirely depends on what you choose to run on them ..23:54
allan_I want to demonstrate it to different schools here in our place23:55
Kiallagain, it entirely depends on what you choose to run on it ..23:55
allan_videos, web apps for elementary students23:56
allan_and the most web apps are for faculty23:56
Kiallthen that depends on the number of concurrent users, the video bitrates etc ..23:56
Kiallno different to a standard webserver in that regard23:57
Kiallopenstack adds no overheads23:57

allan_and all services are running on 1 machine23:58
Kiallallan_: I'm really not sure you are understanding me, OpenStack does not make any use whatsover of an internet connection.23:59
KiallYour internet connection requirements are based on what you choose to run inside openstack23:59
