| samba | hi all - i'm new here - i've got a few high-level design questions, if you don't mind... | 00:12 |
|---|---|---|
| samba | first 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 IRC | 00:15 | |
| kpepple | samba: openstack provides a cloud infrastructure composed of my virtualization hosts, so yes | 00:16 |
| kpepple | s/my/many/ | 00:17 |
| samba | kpepple, thanks for confirming - i just found the video links on openstack.org - i'll review those and let you know if i have more questions | 00:17 |
| kpepple | samba: np | 00:17 |
| *** obino has quit IRC | 00:22 | |
| samba | kpepple, 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 |
| kpepple | it relies on others and supports a wide array: hyperv, xen, KVM, lxc, VMware, etc | 00:25 |
| samba | ok, 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, context | 00:26 | |
| samba | Maybe 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 |

| mattray | crushinator is the single-box install, there's also mom, larry, ignar, walt, hypnotoad, lrrr and morbo | 02:07 |
| mattray | is that a legitimate place to put locks? | 02:08 |

| *** dolphm has joined #openstack | 02:09 | |

| mattray | hmmm... | 02:10 |
| mattray | chmod 777'd it and it quit complaining | 02:10 |
| dsockwell | weeeeird | 02:11 |
| mattray | I don't like that | 02:11 |
| dsockwell | did you shut down the machine less than gracefully? | 02:11 |
| dsockwell | at some point | 02:11 |
| mattray | not exactly | 02:11 |
| dsockwell | so yes? | 02:11 |

| dsockwell | ah | 02:11 |
| dsockwell | same hostname? | 02:11 |
| mattray | I'm writing the Chef cookbooks | 02:11 |
| mattray | I wonder if there was an issue caused by having a 'nova' user before the .deb installed it | 02:12 |
| dsockwell | honestly it's probably on you to clean up better, but maybe you should submit a bug | 02:12 |
| mattray | well, I'll be nuking the box yet again Monday morning. | 02:12 |
| mattray | but yeah, if that's it I'll open a bug | 02:12 |
| mattray | at least now it's complaining about my br100, so that's better | 02:13 |
| mattray | I knew that was broken | 02:13 |

| gholt | j^: 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 |
| gholt | j^: ^^ also how amazon achieves a similar feature, though of course I like ours better. :) | 13:27 |
| *** shentonfreude has joined #openstack | 13:40 | |
| j^ | gholt: how is the performance of segment uploads if you have many segments? | 13:52 |
| *** kashyap has joined #openstack | 13:53 | |
| gholt | j^: 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 files | 13:58 |
| gholt | j^: 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 |
| notmyname | segments can be uploaded concurrently. that will most likely give you better performance that uploading and entire object as one object | 14:01 |
| gholt | The 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 IRC | 14:02 | |
| gholt | notmyname: 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 |
| gholt | j^: 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 |
| gholt | j^: That safety could be removed fairly easy on a private cloud if desired. | 14:04 |
| *** xavicampa has quit IRC | 14:13 | |
| j^ | copy would be limited to 1s/s too? | 14:17 |
| *** koolhead17 has joined #openstack | 14:22 | |
| gholt | j^: Yes, that's true. | 14:24 |
| gholt | j^: If you look on line 164 of http://bazaar.launchpad.net/~hudson-openstack/swift/trunk/view/head:/swift/proxy/server.py | 14:24 |
| gholt | j^: That's where the safety valve is. | 14:24 |
| gholt | I 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 IRC | 14:30 | |

| mattray | I don't know what the best way is yet, I'm still struggling with networking again | 19:19 |
| mattray | vishy: for Flat networking, what goes in the br100? | 19:19 |
| mattray | all the examples have XXX.XXX.XXX.XXX for IPs | 19:19 |
| vishy | flat networking -> don't use it | 19:20 |
| vishy | :) | 19:20 |
| vishy | it requires manual setup of forwarding rules, etc. | 19:21 |
| mattray | ok, what's the easiest solution for Cactus? | 19:21 |
| vishy | flatdhcp | 19:21 |
| mattray | FlatDHCP? | 19:21 |
| vishy | yes | 19:21 |
| vishy | and it should do everything for you | 19:21 |
| vishy | the original recipes i had set it up properly | 19:21 |
| mattray | ok, I'll go look at your cookbooks | 19:22 |
| vishy | mattray: https://gist.github.com/raw/786945/server.rb | 19:24 |
| vishy | with the anso cookbooks and the json in that file it sets up multiple hosts in flatdhcp mode | 19:24 |
| mattray | thanks, I'll dig into that | 19:25 |
| mattray | doing a POC that will go to 400 nodes | 19:25 |
| mattray | I'll be writing it up once we have some lessons learned | 19:27 |
| vishy | mattray: awesome | 19:29 |
| vishy | mattray: we are working on another networking mode that i think will become the default | 19:29 |
| vishy | mattray: its kinda like redundant flatdhcp | 19:29 |
| vishy | flatdhcp without using nova-network as the gateway | 19:29 |
| mattray | sounds good, networking is the part I screw up the most | 19:29 |

| ShermanBoyd | vishy: thanks | 20:53 |
| ShermanBoyd | newopen: I would assume so yes | 20:54 |
| ShermanBoyd | what 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 auth | 20:56 |
| newopen | which configuration should i use? | 20:57 |
| ShermanBoyd | newopen: I probably know less than you, but it sounds like you want vlan | 20:58 |
| ShermanBoyd | newopen: you want to keep two projects from communicating right? | 20:59 |
| newopen | i want that vms with different subnets' addresses be contected to my br100 | 21:00 |
| newopen | can i run two projects in the same physical node? | 21:02 |
| ShermanBoyd | yeah | 21:02 |
| ShermanBoyd | I haven't got as far as the networking ... so I'm afraid I can't help you there | 21:03 |
| ShermanBoyd | but I'm pretty sure you can run two projects on a node | 21:03 |
| newopen | so when i run euca-run-instances,it will show me instances from different subnets | 21:03 |
| ShermanBoyd | are these routable IP addresses? | 21:04 |
| ShermanBoyd | or are they private? | 21:04 |
| newopen | private | 21:04 |
| ShermanBoyd | tell me a little more about your end goal | 21:06 |
| ShermanBoyd | I'm not sure why you wouldn't just fire them up on the same subnet | 21:06 |
| ShermanBoyd | if you want them to be able to talk to each other | 21:06 |
| newopen | yes i want it | 21:07 |
| newopen | they should communicate | 21:07 |
| newopen | that's | 21:07 |
| newopen | why i want them attached to the same bridge br100 | 21:08 |
| newopen | but how will i precise which subnet i would using when i run euca-run-instance | 21:08 |
| ShermanBoyd | I think you want vlan mode ... it creates one bridge per project | 21:09 |
| newopen | and with this mode can i have two subnet per bridge? | 21:10 |
| mattray | lrrr nova-network enabled XXX 2011-05-21 20:02:45 | 21:11 |
| mattray | I must have hosed my networking spectacularly | 21:11 |
| ShermanBoyd | newopen: I think you would create a project for each network | 21:12 |
| ShermanBoyd | newopen: I think the routing table will pick them up and they should be able to communicate if they are on the same node | 21:13 |
| newopen | ShermanBoyd : thanks :) | 21:14 |
| ShermanBoyd | newopen: np , keep in mind this is advice from a noob, but it's my best guess | 21:15 |
| newopen | :)) | 21:17 |
| mattray | anyone know how to debug nova-network? | 21:26 |

| ShermanBoyd | ziyadb: http://docs.openstack.org/cactus/openstack-compute/admin/content/ch_networking.html | 23:11 |
| ShermanBoyd | ziyadb: I think you want at minimum two switches, a public facing network and backend net | 23:12 |
| ziyadb | speaking from a backup and such perspective. | 23:14 |
| ziyadb | vmware vmotion crap for example requires L2 adjacency | 23:14 |
| ziyadb | just making sure the datacenter design goes well. | 23:14 |

| ShermanBoyd | my testbed has 3 gigabit networks, public facing, storage/backup, and a managment network | 23:15 |
| ziyadb | elaborate a bit on storage/backup? | 23:17 |
| ShermanBoyd | it's just a switch dedicated to storage traffic and backup traffic | 23:18 |

| ShermanBoyd | what are your plans and what is your application; general purpose multi-tenant cloud computing? Private cloud? | 23:21 |
| ziyadb | hosted services, going to run a voip app over it. | 23:22 |
| ziyadb | redundancy and resilience are of the utmost importance, hence it needs to be distributed. | 23:22 |
| ShermanBoyd | my design is to use local storage but I want to use either swift or glusterfs to replicate the vms across the nodes | 23:24 |
| ShermanBoyd | so it's a little different than the frontend server pulling from the huge storage cluster that you usually do | 23:26 |
| ziyadb | and you can do so over routing, right? No L2 adjacency crap required. | 23:26 |
| ShermanBoyd | I don't think that's a problem | 23:26 |
| ShermanBoyd | My routers are managed, but as long as all your equipment understands vlan tagging I bet you could get away with unmanaged | 23:27 |
| ShermanBoyd | how big is your buildout? | 23:29 |
| *** zns has joined #openstack | 23:31 | |
| ziyadb | well, it's under planning | 23:32 |
| ziyadb | but looking to service ~1k customers | 23:32 |
| ShermanBoyd | have you thought about hiring rackspace cloud builders | 23:33 |
| ziyadb | not sure if management did. | 23:34 |
| ShermanBoyd | I'm definitely considering it ... they will help you roll out your openstack cloud, training etc | 23:35 |
| ziyadb | yup, looking at their site. | 23:35 |
| ShermanBoyd | it might not be a bad idea especially if it's a large deployment | 23:35 |
| ShermanBoyd | avoid some costly mistakes | 23:36 |
| ziyadb | agreed | 23:36 |
| ShermanBoyd | also could speed up your deployment | 23:36 |
| ziyadb | will definitely consider it, thanks! | 23:38 |
