Time Nick Message 21:19 pdurbin wow, sounds like running openstack on centos was pretty rough in january 2011: Blake Yeager - Deployment Strategies - OpenStack Austin Meetup - December 8th, 2011 http://www.youtube.com/watch?v=RtvegVNnJ_4#t=3m42s 21:19 pdurbin and that most people continue to run openstack on ubuntu 21:35 pdurbin hmm, this video talks about how much intelligence is expected to be built into the web applications built on top of openstack. OpenStack Basics - Overview: http://www.youtube.com/watch?v=c1GFoY4btpo 21:37 pdurbin ... that the design of openstack assumes some openstack components can fail and that the web application can deal with the failure 21:53 pdurbin nice that that video is linked from http://wiki.openstack.org/DemoVideos 21:55 pdurbin hmm, "XFS is considered to be the best option" -- http://docs.openstack.org/diablo/openstack-compute/starter/content/Swift_Object_Server-d1e291.html 22:05 pdurbin woof, this is starting to get a bit involved... http://docs.openstack.org/diablo/openstack-compute/starter/content/Nova_conf-d2s367.html 22:06 pdurbin sudo mkfs.xfs -i size=1024 /dev/sdb1 22:07 pdurbin yeah, definitely pushing xfs: http://docs.openstack.org/diablo/openstack-compute/starter/content/Swift_configuration.html 22:09 pdurbin "string that can never change (DO NOT LOSE)" heh. http://docs.openstack.org/diablo/openstack-compute/starter/content/Swift_hash_configuration.html 22:14 pdurbin "Sometimes you may have XXX instead of the smiley" heh. http://docs.openstack.org/diablo/openstack-compute/starter/content/Nova_Components_nova-compute_alone_-d1e1123.html 22:21 pdurbin i have to agree with sjoeboo's comments from friday that all this image creation seems like a pain compared to kickstart: http://docs.openstack.org/diablo/openstack-compute/starter/content/OS_Installation-d1e1298.html 22:35 pdurbin "Currently we assume that all images have a kernel image and a ramdisk. Modern hypervisors on modern VMs can run raw disk images, without the complexity of a separate ramdisk/kernel image" https://blueprints.launchpad.net/nova/+spec/raw-disk-images 22:42 pdurbin shuff: i know you like Eucalyptus. you'll be happy to see openstack uses its command line tool: http://docs.openstack.org/diablo/openstack-compute/starter/content/Euca2ools-Command_Line_Tools-d1e1828.html 22:44 pdurbin euca-get-console-output. nice 22:46 pdurbin hmm. "The storage on the instances is non persistent in nature and hence any data that you generate and store on the file system on the first disk of the instance gets lost when the instance is terminated." 22:47 pdurbin "You will need to use persistent volumes provided by nova-volume if you want any data generated during the life of the instance to persist after the instance is terminated." http://docs.openstack.org/diablo/openstack-compute/starter/content/Nova-volume-d1e2000.html 22:48 pdurbin it's not clear to me how to persist the VMs, which seems rather important 22:52 pdurbin Q: "How to make a vm persistent?" https://answers.launchpad.net/nova/+question/149350 A: "You need to bundle your running instance, upload it and register it to create a new image." 22:54 pdurbin gonna have to ask westmaas about that one... coming from vmware and kvm, we're used to our 22:54 pdurbin VMs being persistent 22:58 pdurbin "Nova stores the data related to the projects, users, resources etc. in a database, by default in a MySQL database." mysql by default, i guess. http://docs.openstack.org/diablo/openstack-compute/starter/content/Database_Management-d1e2713.html 22:59 pdurbin still not clear to me what a "project" is. not really defined at http://docs.openstack.org/diablo/openstack-compute/starter/content/Project_Management-d1e2672.html 23:01 pdurbin the networking section is pretty light. basically just a pointer to http://docs.openstack.org/openstack-compute/admin/content/ch04.html 23:02 pdurbin ah, at least that page says "A Compute project consists of a number of VM instances created by a user" 23:04 westmaas yeah, the idea is you can have multiple users with access to the same project 23:04 westmaas its basically an auth boundary 23:04 pdurbin oh hey, westmaas :) 23:04 westmaas :) 23:05 pdurbin i thought i was talking to myself 23:05 pdurbin i thought i had invented a new form of blogging :) 23:05 westmaas do you care about data being persisted after you delete an instance? 23:05 westmaas haha 23:05 westmaas or only being there after reboots, and the like. 23:05 pdurbin well, delete sounds so. . . final 23:06 pdurbin what if i shutdown a vm for a while 23:06 pdurbin and someone complains 23:06 pdurbin so i turn it back on 23:06 pdurbin is the vm as-is? 23:06 westmaas yeah, that'd be fine. 23:06 westmaas I think openstack does support amazon style ephemeral instances, but I don't really know anything about that. 23:07 westmaas by defaults our instances are more permanent 23:07 pdurbin ok. good 23:07 pdurbin uh oh, wife and kids coming up the stairs 23:07 pdurbin at least i finished that intro doc 23:07 westmaas haha 23:07 westmaas cool 23:08 westmaas also jan 2011 is soooo long ago :) 23:08 westmaas That's before my team started on the project!
