sambahi all - i'm new here - i've got a few high-level design questions, if you don't mind...00:12
sambafirst off, it looks like openstack is a set of tools for managing cloud infrastructure on multiple virtualization platforms - is that accurate?00:14
samba(trying to understand openstack, how it fits in...)00:15
*** joearnold has quit IRC00:15
kpepplesamba: openstack provides a cloud infrastructure composed of my virtualization hosts, so yes00:16
sambakpepple, thanks for confirming - i just found the video links on - i'll review those and let you know if i have more questions00:17
kpepplesamba: np00:17
*** obino has quit IRC00:22
sambakpepple, so does openstack manage other virtualization platforms? or is it its own? (does it rely on some specific platform, e.g. KVM, or is it generic?)00:23
kpeppleit relies on others and supports a wide array: hyperv, xen, KVM, lxc, VMware, etc00:25
sambaok, and the storage and image services - do they simply provide interfaces to SAN or something on that order?00:26
* samba is trying to understand architecture, context00:26
sambaMaybe some comparison would help... I'm reasonably familiar with Amazon AWS... OpenStack Compute is like EC2, image services is like EBS, and storage service is like S3 - right?00:31

mattrayyeah, there's a theme02:07
dsockwellmine is battletech02:07
dsockwellthere's a lockfile it's complaining about02:07
dsockwell(nova.exception): TRACE: LockFailed: failed to create /usr/lib/pymodules/python2.6/crushinator.Dummy-6-2850002:07
mattraycrushinator is the single-box install, there's also mom, larry, ignar, walt, hypnotoad, lrrr and morbo02:07

dsockwelli saw someone mention it here yesterday02:09
mattraychmod 777'd it and it quit complaining02:10
mattrayI don't like that02:11
dsockwelldid you shut down the machine less than gracefully?02:11

mattraynot exactly02:11
dsockwellso yes?02:11
mattrayI've been doing automated installs on it all day02:11
dsockwellsame hostname?02:11
mattrayI'm writing the Chef cookbooks02:11
mattrayI wonder if there was an issue caused by having a 'nova' user before the .deb installed it02:12
dsockwellhonestly it's probably on you to clean up better, but maybe you should submit a bug02:12
mattraywell, I'll be nuking the box yet again Monday morning.02:12
mattraybut yeah, if that's it I'll open a bug02:12
mattrayat least now it's complaining about my br100, so that's better02:13
mattrayI knew that was broken02:13

gholtj^: No, there are no plans for ranged puts in swift at this time. It's a lengthy discussion as to why. A replacement for such are multipart uploads, where you upload segments of the final object as separate smaller objects, then join them once done.13:26
gholtj^: ^^ also how amazon achieves a similar feature, though of course I like ours better. :)13:27
*** shentonfreude has joined #openstack13:40
j^gholt: how is the performance of segment uploads if you have many segments?13:52
*** kashyap has joined #openstack13:53
gholtj^: Segmented uploads are really the same as that many regular uploads. For example, you upload s/1 s/2 and s/3 then create a marker object with the desired object name, say o that points to s/*. Downloading o means you get the objects at s/* concatenated together as one stream.13:57
j^gholt: yes, but was wondering what a good segement size is, would want to add chunks in 1Mb blocks and not sure if that would be an issue with 1Gb files13:58
gholtj^: Gotcha. Yes that can get tricky. In such a case you're probably best off doing a COPY command once you're done from the segmented object to a whole object for the better performance.14:00
notmynamesegments can be uploaded concurrently. that will most likely give you better performance that uploading and entire object as one object14:01
gholtThe COPY command is a server-side copy that always creates a non-segmented object, even if the source is a segmented object.14:01
*** osier has quit IRC14:02
gholtnotmyname: I think he was wondering the impact on downloading a 1000 segmented object. Which in the currently implementation would take a minimum of 1000 seconds.14:02
gholtj^: There is a safety valve in Swift where it will (currently) only allow 1 segment per second be downloaded, mostly to keep a user from uploading a bunch of 1-byte segments and increasing the load on the cluster to crazy levels.14:04
gholtj^: That safety could be removed fairly easy on a private cloud if desired.14:04
*** xavicampa has quit IRC14:13
j^copy would be limited to 1s/s too?14:17
*** koolhead17 has joined #openstack14:22
gholtj^: Yes, that's true.14:24
gholtj^: If you look on line 164 of
gholtj^: That's where the safety valve is.14:24
gholtI based that arbitrary 1 segment per second rate because it allowed 100M segments to be served at 1Gbit rates, which seemed a reasonable start. :)14:26
*** jaypipes has quit IRC14:30
gholt[I'll go make a bug to get that added as a conf option.]14:36

mattrayI don't know what the best way is yet, I'm still struggling with networking again19:19
mattrayvishy: for Flat networking, what goes in the br100?19:19
mattrayall the examples have XXX.XXX.XXX.XXX for IPs19:19
vishyflat networking -> don't use it19:20
vishyit requires manual setup of forwarding rules, etc.19:21
mattrayok, what's the easiest solution for Cactus?19:21
vishyand it should do everything for you19:21
vishythe original recipes i had set it up properly19:21
mattrayok, I'll go look at your cookbooks19:22
vishywith the anso cookbooks and the json in that file it sets up multiple hosts in flatdhcp mode19:24
mattraythanks, I'll dig into that19:25
mattraydoing a POC that will go to 400 nodes19:25
mattrayI'll be writing it up once we have some lessons learned19:27
vishymattray: awesome19:29
vishymattray: we are working on another networking mode that i think will become the default19:29
vishymattray: its kinda like redundant flatdhcp19:29
vishyflatdhcp without using nova-network as the gateway19:29
mattraysounds good, networking is the part I screw up the most19:29
katkeehi, just a quick question. i installed one openstack node with every components, now i am trying to install a second one with compute and network but compute doesn't find the base images and kvm complains... how is this node supposed to get AMIs?19:30

newopencan i have instances running with addresses from different subnets in the same node20:53
ShermanBoydvishy:  thanks20:53
ShermanBoydnewopen: I would assume so yes20:54
ShermanBoydwhat should I use for authorization ... I'd like to go ldap.  I'm looking at OpenLDAP and 389 Directory.  Eventually I'd like to see some two-factor auth20:56
newopenwhich configuration should i use?20:57
ShermanBoydnewopen: I probably know less than you, but it sounds like you want vlan20:58
ShermanBoydnewopen: you want to keep two projects from communicating right?20:59
newopeni want that vms with different subnets' addresses be contected to my br10021:00
newopen can i run two projects in the same physical node?21:02
ShermanBoydI haven't got as far as the networking ... so I'm afraid I can't help you there21:03
ShermanBoydbut I'm pretty sure you can run two projects on a node21:03
newopenso when i run euca-run-instances,it will show me instances from different subnets21:03
ShermanBoydare these routable IP addresses?21:04
ShermanBoydor are they private?21:04
ShermanBoydtell me a little more about your end goal21:06
ShermanBoydI'm not sure why you wouldn't just fire them up on the same subnet21:06
ShermanBoydif you want them to be able to talk to each other21:06
newopenyes i want it21:07
newopenthey should communicate21:07
newopenwhy i want them attached to the same bridge br10021:08
newopenbut how will i precise which subnet i would using when i run euca-run-instance21:08
ShermanBoydI think you want vlan mode ... it creates one bridge per project21:09
newopenand with this mode can i have two subnet per bridge?21:10
mattraylrrr       nova-network enabled  XXX 2011-05-21 20:02:4521:11
mattrayI must have hosed my networking spectacularly21:11
ShermanBoydnewopen: I think you would create a project for each network21:12
ShermanBoydnewopen: I think the routing table will pick them up and they should be able to communicate if they are on the same node21:13
newopenShermanBoyd : thanks :)21:14
ShermanBoydnewopen: np , keep in mind this is advice from a noob, but it's my best guess21:15
