| oneman | hello | 01:25 |
|---|---|---|
| oneman | I really want to use a high-cpu-medium instance on EC2, but It won't let me choose that with the maverick 10.10 ami | 01:26 |
| erichammond | oneman: You have to pick the 32-bit AMI for c1.medium, not the 64-bit AMI | 01:26 |
| oneman | Whats the reason behind that? | 01:27 |
| erichammond | c1.medium is 32-bit. | 01:27 |
| oneman | I have used 64bit on c1.medium | 01:27 |
| oneman | let me double check | 01:27 |
| erichammond | oneman: No you haven't :) | 01:27 |
| erichammond | c1.medium is a nice machine, though. Good performance as long as you don't need lots of memory. | 01:27 |
| oneman | indeed | 01:27 |
| oneman | oops ;P | 01:27 |
| oneman | I'm actually trying to do something new and crazy | 01:28 |
| oneman | Run jackd on the cloud | 01:28 |
| oneman | 1024 sample period is fine tho | 01:28 |
| oneman | so its not super tight.. | 01:28 |
| erichammond | oneman: I just read about JACK yesterday. My son is interested in connecting his MIDI keyboard to Ubuntu and I have no idea how to set all that up. | 01:29 |
| oneman | start jack, plug in the keyboard, and then start a program that can make use of the keyboard | 01:29 |
| oneman | I've only used a generic akai drum machine pad thing... with hydrogen drum machine and jack and ardour | 01:30 |
| erichammond | oneman: I'm lost at the "plug in" point. Not sure if I have to get a special audio card with MIDI support that works with Ubuntu. | 01:30 |
| oneman | qjackctl | 01:30 |
| oneman | is it not usb? | 01:30 |
| erichammond | oneman: If that works, I could buy a MIDI to USB cable. Or perhaps we should get a more modern keyboard. | 01:31 |
| oneman | Heres the basic info, you use qjackctl gui program to launch/start/stop jackd, you use ardour for recording/playback, and then whatever other programs to work with the midi keyboard / drum machine etc | 01:31 |
| oneman | yeah, midi to usb cable sounds good to me | 01:32 |
| oneman | anything recent will be midi via usb tho | 01:32 |
| oneman | let me ask you another thing about the cloud, I could have shot myself in the foot here but luckily I had only messed with the instance for about an hour | 01:32 |
| erichammond | Thanks. I took us offtopic, but it's a slow channel. | 01:32 |
| oneman | So, I loaded up that AMI, it had EBS as / , so I expected if I terminated the instance that I would still have my ebs volume | 01:33 |
| oneman | but it got deleted when I terminated! | 01:33 |
| oneman | How do I clone it or something ? | 01:33 |
| erichammond | terminate: you lose any volumes that EC2 created for you automatically on startup | 01:33 |
| erichammond | stop: all the volumes are kept. | 01:33 |
| oneman | But if the volume was not created by ec2 and I terminate it still sticks right? | 01:34 |
| erichammond | right | 01:34 |
| oneman | could I snapshot the volume, then restore it to another volume in order to "copy" it? | 01:34 |
| erichammond | There is an override option that goes either way. | 01:35 |
| oneman | where is this over ride :! | 01:35 |
| erichammond | Check out #2 in http://alestic.com/2010/01/ec2-instance-locking | 01:35 |
| erichammond | Yes, you can snapshot the root EBS volume, register it as an AMI, and start a new instance from that. | 01:37 |
| erichammond | It is recommended that you initiate the snapshot while the instance is stopped to reduce risk of file system inconsistencies. | 01:37 |
| oneman | ok great | 01:37 |
| oneman | thats really what I want | 01:37 |
| erichammond | There is an API / command line that does all of this for you (including stopping/starting the instance) | 01:38 |
| erichammond | er, does all of this through registering the AMI. It does not start a new instance. | 01:38 |
| oneman | glad I figured this one out before setting up my environment | 01:38 |
| oneman | hehe | 01:38 |
| erichammond | I still recommend starting from a fresh public AMI and running an automated script to set up your software and configuration whenever this approach might work. | 01:39 |
| erichammond | This lets you keep up with the latest AMIs and makes it easier to switch to new OS releases as they come out. | 01:39 |
| erichammond | In place upgrades are supposed to work, but I almost always have issues. | 01:40 |
| erichammond | I also recommend keeping your data on a separate EBS volume. | 01:40 |
| oneman | lemme ask you this, I set myself up a development server at home, also 10.10, and except for the programs I compiled myself (which are the ones I'm writing anyway), I installed a load of dependancies (luckily all came from standard ubuntu repos as well), whats the easiest way to just clone this list of packages, so I don't have to just try to compile and see what I'm missing 10 times over ( and also have an exact knowled | 01:41 |
| oneman | ge of my actual dependencies ) | 01:41 |
| oneman | All my usage of the cloud so far has been through engineyard's sort of web interface to ec2 | 01:42 |
| oneman | so thats why I'm kind of half way on my cloud knowledge | 01:43 |
| erichammond | oneman: I think I've used this in the past: dpkg --get-selections | 01:45 |
| oneman | is it feasable to mount /home as your seperate ebs volume | 01:45 |
| erichammond | then on the target machine : dpkg --set-selections < OUTPUTFROMABOVE ; apt-get dselect-upgrade | 01:45 |
| oneman | or do you reccomend a /data or /app | 01:45 |
| erichammond | oneman: Yes. I mount an EBS volume on, say, /vol then mount --bind directories from there over top of /home, /etc/lib/mysql, /etc/log/mysql, etc. | 01:46 |
| oneman | ok | 01:47 |
| erichammond | See: http://ec2ebs-mysql.notlong.com | 01:47 |
| oneman | I'm a postgresql user ;p | 01:48 |
| erichammond | oneman: See that article for the principles involved. | 01:48 |
| erichammond | in moving data around on EBS and mounting it back. | 01:48 |
| oneman | ok thanks alot | 01:48 |
| oneman | this is all exactly the information I needed | 01:49 |
| oneman | 2 upgraded, 1267 newly installed, 0 to remove and 0 not upgraded. | 02:01 |
| oneman | Need to get 919MB of archives. | 02:01 |
| oneman | After this operation, 2,980MB of additional disk space will be used. | 02:01 |
| oneman | exciting! | 02:01 |
| oneman | haha | 02:01 |
| mwhudson | it seems that starting ami-ec1aea85 (today's 64 bit instance store in us-east-1) on an m1.xlarge instance doesn't work very well | 03:39 |
| mwhudson | [1122470.505234] Kernel panic - not syncing: Attempted to kill init! | 03:40 |
| mwhudson | in the console outptu | 03:40 |
| erichammond | mwhudson: Please submit a bug report in launchpad.net | 03:40 |
| mwhudson | erichammond: which project? | 03:40 |
| mwhudson | ah ubuntu-on-ec2 i guess | 03:44 |
| mwhudson | ah bah, the second one i tried worked fine | 03:45 |
| mwhudson | yay reliability :( | 03:45 |
| flaccid | you could still raise the bug as intermittant and show the whole console output | 03:45 |
| mwhudson | yeah | 03:46 |
| oneman | ok so I use a public ami, then I snapshot the ebs vol, create a new volume from that, attach that to the original instance (when it was stopped) and it won't boot | 06:14 |
| oneman | what noobie mistake am I making | 06:14 |
| oneman | I set it to /dev/sda instead of /dev/sda1 | 06:39 |
| oneman | hard to believe it let me shoot myself in the foot like that ;p | 06:40 |
| ubuntucloud845 | hello | 08:05 |
| ubuntucloud845 | can i auto back up file server to another server | 08:05 |
| ubuntucloud845 | same ubunto 10.10 | 08:05 |
| superxgl | hi all, i used hybirdfox, and my image is based on i386, but why hybirdfox shows the architecture is X86_64?? | 11:47 |
| flaccid | superxgl: check the api | 12:07 |
| TeTeT | superxgl: maybe it has been uploaded as x86_64, check the output of euca-describe-images for that image | 12:07 |
| superxgl | IMAGE eri-89321725 centos-ramdisk-buket/initrd.img-2.6.24-19-xen.manifest.xml admin available public x86_64 ramdisk instance-store | 12:10 |
| superxgl | IMAGE emi-CD7E14B8 centos-image-buket/centos.5-3.x86.img.manifest.xml admin available public x86_64 machine eki-27E215E0 eri-89321725 instance-store | 12:10 |
| superxgl | IMAGE eki-27E215E0 centos-kernel-buket/vmlinuz-2.6.24-19-xen.manifest.xml admin available public x86_64 kernel instance-store | 12:10 |
| superxgl | oh, what happened? | 12:11 |
| superxgl | i used the eucalyptus's image | 12:11 |
| TeTeT | superxgl: it's been stored as x86_64 as the output says | 12:11 |
| superxgl | why? but my image is i386 | 12:12 |
| TeTeT | but should be not a problem, I'd continue testing if I where you | 12:12 |
| flaccid | thats what it was registered as | 12:12 |
| TeTeT | superxgl: when you upload the image you can specify which architecture it is | 12:12 |
| superxgl | hmm.. | 12:12 |
| superxgl | i have to do this ? | 12:12 |
| superxgl | i follwed the guideline and it did not say that | 12:13 |
| TeTeT | superxgl: if it comes from the image store and you think it's an error, please file a bug in Launchpad against the image store | 12:13 |
| TeTeT | superxgl: which guideline? | 12:13 |
| superxgl | http://open.eucalyptus.com/wiki/EucalyptusInstallationSource_v2.0 | 12:14 |
| superxgl | but when i loged in the instance , "uname -a" shows that it is i386 | 12:15 |
| flaccid | sure thats because the kernel is i386 | 12:16 |
| flaccid | the image was registered as x86_64 in the api | 12:16 |
| superxgl | hmm... | 12:16 |
| superxgl | flaccid: so where to check the api? | 12:17 |
| superxgl | TeTeT: when i upload the image how to specify the architecture ? sry, im new to this | 12:19 |
| flaccid | superxgl: http://open.eucalyptus.com/wiki/Euca2oolsUsingOverview_v1.3 http://open.eucalyptus.com/wiki/Euca2oolsImageManagement_v1.3 | 12:19 |
| superxgl | im checking now | 12:22 |
| superxgl | oh, i found the problem as "euca-bundle-image --help" shows : | 12:42 |
| superxgl | -r, --arch Target architecture for the image ('x86_64' or 'i386' default: 'x86_64'). | 12:42 |
| flaccid | right | 12:43 |
| flaccid | and keep in mind euca-register | 12:43 |
| superxgl | i will ..tnx very much for all of ur help :) | 12:43 |
| flaccid | np | 12:43 |
| kim0 | Hi folks, any help answering questions on the forums is appreciated http://ubuntuforums.org/forumdisplay.php?f=392 | 13:07 |
| willem | I want to create a tar.gz of some directories in an S3 bucket. I have got that mounted using s3fs. And it seems to go fine, however after some time it fails with the following message: gzip: stdout: No space left on device | 13:26 |
| kim0 | willem: seems like your output directory has run out of space | 13:45 |
| willem | @kim8 it is an s3 bucket, which I do have write access to... | 13:46 |
| willem | I am just thinking... I might be going over the maximum file size.... | 13:47 |
| kim0 | willem: why don't you create the tgz file locally .. then upload that | 13:49 |
| willem | Because all the data is already on the S3, lots of small files... | 13:49 |
| willem | That is why I want a tar. To be able to download and verify the download easily. | 13:50 |
| kim0 | so, you have many little files on S3, you want to compress those files into a tar file that is written to local disk ? | 13:51 |
| kim0 | willem: ^ | 13:54 |
| kim0 | is walrus throughput as slow as 5MB/s ? | 13:59 |
| willem | No, I want to compress (or at least tar them) into one file. So that other people can download it from s3. | 14:05 |
| kim0 | willem: I would suggest compressing them into a local .tar.gz file first, then uploading that to S3 as a second step | 14:31 |
| willem | kim0: ok, currently trying zip using a split at 4gig. If that doesn't work, I will try it your way :) | 14:32 |
| willem | thanks for the help! | 14:32 |

| elasticdog | possibly a stupid question, but can you use `euca_conf` to set arbitrary variable values? | 16:58 |
| elasticdog | it seems like there are flags for setting a few specific things, and --name to read any variable's value, but how would you set something like MAX_CORES...just add it by hand? | 16:58 |
