=== dendrobates is now known as dendro-afk === dendro-afk is now known as dendrobates [01:25] hello [01:26] 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] oneman: You have to pick the 32-bit AMI for c1.medium, not the 64-bit AMI [01:27] Whats the reason behind that? [01:27] c1.medium is 32-bit. [01:27] I have used 64bit on c1.medium [01:27] let me double check [01:27] oneman: No you haven't :) [01:27] c1.medium is a nice machine, though. Good performance as long as you don't need lots of memory. [01:27] indeed [01:27] oops ;P [01:28] I'm actually trying to do something new and crazy [01:28] Run jackd on the cloud [01:28] 1024 sample period is fine tho [01:28] so its not super tight.. [01:29] 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] start jack, plug in the keyboard, and then start a program that can make use of the keyboard [01:30] I've only used a generic akai drum machine pad thing... with hydrogen drum machine and jack and ardour [01:30] 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] qjackctl [01:30] is it not usb? [01:31] oneman: If that works, I could buy a MIDI to USB cable. Or perhaps we should get a more modern keyboard. [01:31] 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 [01:32] yeah, midi to usb cable sounds good to me [01:32] anything recent will be midi via usb tho [01:32] 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] Thanks. I took us offtopic, but it's a slow channel. [01:33] 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] but it got deleted when I terminated! [01:33] How do I clone it or something ? [01:33] terminate: you lose any volumes that EC2 created for you automatically on startup [01:33] stop: all the volumes are kept. [01:34] But if the volume was not created by ec2 and I terminate it still sticks right? [01:34] right [01:34] could I snapshot the volume, then restore it to another volume in order to "copy" it? [01:35] There is an override option that goes either way. [01:35] where is this over ride :! [01:35] Check out #2 in http://alestic.com/2010/01/ec2-instance-locking [01:37] Yes, you can snapshot the root EBS volume, register it as an AMI, and start a new instance from that. [01:37] It is recommended that you initiate the snapshot while the instance is stopped to reduce risk of file system inconsistencies. [01:37] ok great [01:37] thats really what I want [01:38] There is an API / command line that does all of this for you (including stopping/starting the instance) [01:38] er, does all of this through registering the AMI. It does not start a new instance. [01:38] glad I figured this one out before setting up my environment [01:38] hehe [01:39] 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] This lets you keep up with the latest AMIs and makes it easier to switch to new OS releases as they come out. [01:40] In place upgrades are supposed to work, but I almost always have issues. [01:40] I also recommend keeping your data on a separate EBS volume. [01:41] 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] ge of my actual dependencies ) [01:42] All my usage of the cloud so far has been through engineyard's sort of web interface to ec2 [01:43] so thats why I'm kind of half way on my cloud knowledge [01:45] oneman: I think I've used this in the past: dpkg --get-selections [01:45] is it feasable to mount /home as your seperate ebs volume [01:45] then on the target machine : dpkg --set-selections < OUTPUTFROMABOVE ; apt-get dselect-upgrade [01:45] or do you reccomend a /data or /app [01:46] 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. [01:47] ok [01:47] See: http://ec2ebs-mysql.notlong.com [01:48] I'm a postgresql user ;p [01:48] oneman: See that article for the principles involved. [01:48] in moving data around on EBS and mounting it back. [01:48] ok thanks alot [01:49] this is all exactly the information I needed [02:01] 2 upgraded, 1267 newly installed, 0 to remove and 0 not upgraded. [02:01] Need to get 919MB of archives. [02:01] After this operation, 2,980MB of additional disk space will be used. [02:01] exciting! [02:01] haha [03:39] 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 [03:40] [1122470.505234] Kernel panic - not syncing: Attempted to kill init! [03:40] in the console outptu [03:40] mwhudson: Please submit a bug report in launchpad.net [03:40] erichammond: which project? [03:44] ah ubuntu-on-ec2 i guess [03:45] ah bah, the second one i tried worked fine [03:45] yay reliability :( [03:45] you could still raise the bug as intermittant and show the whole console output [03:46] yeah [06:14] 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] what noobie mistake am I making [06:39] I set it to /dev/sda instead of /dev/sda1 [06:40] hard to believe it let me shoot myself in the foot like that ;p [08:05] hello [08:05] can i auto back up file server to another server [08:05] same ubunto 10.10 [11:47] hi all, i used hybirdfox, and my image is based on i386, but why hybirdfox shows the architecture is X86_64?? [12:07] superxgl: check the api [12:07] superxgl: maybe it has been uploaded as x86_64, check the output of euca-describe-images for that image [12:10] 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] 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] IMAGE eki-27E215E0 centos-kernel-buket/vmlinuz-2.6.24-19-xen.manifest.xml admin available public x86_64 kernel instance-store [12:11] oh, what happened? [12:11] i used the eucalyptus's image [12:11] superxgl: it's been stored as x86_64 as the output says [12:12] why? but my image is i386 [12:12] but should be not a problem, I'd continue testing if I where you [12:12] thats what it was registered as [12:12] superxgl: when you upload the image you can specify which architecture it is [12:12] hmm.. [12:12] i have to do this ? [12:13] i follwed the guideline and it did not say that [12:13] 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] superxgl: which guideline? [12:14] http://open.eucalyptus.com/wiki/EucalyptusInstallationSource_v2.0 [12:15] but when i loged in the instance , "uname -a" shows that it is i386 [12:16] sure thats because the kernel is i386 [12:16] the image was registered as x86_64 in the api [12:16] hmm... [12:17] flaccid: so where to check the api? [12:19] TeTeT: when i upload the image how to specify the architecture ? sry, im new to this [12:19] superxgl: http://open.eucalyptus.com/wiki/Euca2oolsUsingOverview_v1.3 http://open.eucalyptus.com/wiki/Euca2oolsImageManagement_v1.3 [12:22] im checking now [12:42] oh, i found the problem as "euca-bundle-image --help" shows : [12:42] -r, --arch Target architecture for the image ('x86_64' or 'i386' default: 'x86_64'). [12:43] right [12:43] and keep in mind euca-register [12:43] i will ..tnx very much for all of ur help :) [12:43] np [13:07] Hi folks, any help answering questions on the forums is appreciated http://ubuntuforums.org/forumdisplay.php?f=392 [13:26] 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 [13:45] willem: seems like your output directory has run out of space [13:46] @kim8 it is an s3 bucket, which I do have write access to... [13:47] I am just thinking... I might be going over the maximum file size.... [13:49] willem: why don't you create the tgz file locally .. then upload that [13:49] Because all the data is already on the S3, lots of small files... [13:50] That is why I want a tar. To be able to download and verify the download easily. [13:51] so, you have many little files on S3, you want to compress those files into a tar file that is written to local disk ? [13:54] willem: ^ [13:59] is walrus throughput as slow as 5MB/s ? [14:05] No, I want to compress (or at least tar them) into one file. So that other people can download it from s3. [14:31] willem: I would suggest compressing them into a local .tar.gz file first, then uploading that to S3 as a second step [14:32] kim0: ok, currently trying zip using a split at 4gig. If that doesn't work, I will try it your way :) [14:32] thanks for the help! === dendrobates is now known as dendro-afk === dendro-afk is now known as dendrobates [16:58] possibly a stupid question, but can you use `euca_conf` to set arbitrary variable values? [16:58] 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? === dendrobates is now known as dendro-afk === dendro-afk is now known as dendrobates === dendrobates is now known as dendro-afk === dendro-afk is now known as dendrobates === dendrobates is now known as dendro-afk === dendro-afk is now known as dendrobates === dendrobates is now known as dendro-afk === dendro-afk is now known as dendrobates === erichammond1 is now known as erichammond === erichammond1 is now known as erichammond === erichammond1 is now known as erichammond
