| davinci11 | hello | 02:32 |
|---|---|---|
| davinci11 | does anyone tested/using EBS based instance ? | 02:32 |
| flaccid | sure | 02:33 |
| flaccid | i don't use instance-store | 02:33 |
| davinci11 | does it work ? | 02:33 |
| flaccid | of course | 02:33 |
| flaccid | otherwise i wouldn't use it | 02:33 |
| flaccid | though this in ec2 not UEC. | 02:34 |
| flaccid | i don't use eucalyptus/uec coz its buggy as | 02:34 |
| davinci11 | <flaccid> : so u use ? | 02:35 |
| flaccid | huh | 02:35 |
| davinci11 | u dont use eucalyptus/uec then what u using now | 02:36 |
| flaccid | flaccid: though this in ec2 not UEC. | 02:36 |
| flaccid | otherwise openstack or cloudstack for private cloud | 02:37 |
| davinci11 | Amazon Elastic Compute Cloud ? | 02:38 |
| flaccid | yes | 02:38 |
| davinci11 | need to pay though | 02:38 |
| flaccid | indeed | 02:39 |
| flaccid | there is the aws free tier though tm | 02:40 |
| flaccid | *atm | 02:40 |

| davinci11 | <flaccid> : did u tested EBS based instance exercise ? | 02:43 |
| flaccid | flaccid: sure | 02:44 |
| flaccid | i build images too, that includes ebs AMIs. | 02:44 |
| davinci11 | $ euca-run-instances -t m1.large -k <KEY> <EMI> | 02:44 |
| flaccid | flaccid: i don't use eucalyptus/uec coz its buggy as | 02:44 |
| flaccid | anything else i should repeat? | 02:44 |
| davinci11 | Note: that the EMI used here cannot be the loader EMI provided in step 2 | 02:45 |
| davinci11 | it say that EMI not the loader EMI provided in step 2, then what should i put | 02:46 |
| flaccid | if someone can help, they'll respond. please be patient. | 02:46 |
| flaccid | i can give a tip though, read the docs | 02:54 |
| davinci11 | i'm confusing thats why i ask for help | 03:00 |

| davinci11 | cant execute this command [$ eval $(blkid lucid-server-uec-amd64.img | cut -f2- -d” | 06:37 |
| davinci11 | “) | 06:37 |
| davinci11 | ] what wrong ? | 06:37 |
| flaccid | eeek, that looks dodgy | 06:40 |
| flaccid | also most of it came through as incompatible encoding | 06:40 |
| flaccid | and i didn't see an error output or anything. | 06:40 |
| davinci11 | then the execise give wrong command ?? | 06:41 |
| _et | ttx: hi. Was there at UCD. Got a clarification to make. good time? | 06:59 |
| _et | can anyone please clarify how control flows when there is an API call to attach a volume to an instance? | 07:03 |
| _et | nova places a request for a volume on the queue and then does the control flow to the scheduler or to the nova-volume? | 07:03 |
| davinci11 | eval $(blkid lucid-server-uec-amd64.img | cut -f2- -d” | 07:14 |
| davinci11 | “) | 07:14 |
| davinci11 | should i replace blkid with value ?? | 07:14 |
| flaccid | davinci11: sounds more like pebkac to me. still i have no idea what you are following. | 07:43 |
| davinci11 | another funny thing $ euca-attach-volume $vol -i <INSTANCEID> -d /dev/sdb | 07:50 |
| davinci11 | 07:50 | |
| flaccid | if you want help, you are may have to learn to ask better. | 07:50 |
| davinci11 | sdb doesn't show up in /dev | 07:50 |
| flaccid | its probably not in your block device mapping for the instance or image | 07:51 |
| flaccid | oh | 07:51 |
| flaccid | this is to attach | 07:51 |
| flaccid | it won't be there until you attach.. | 07:51 |
| flaccid | you are telling it where to attach. | 07:51 |
| davinci11 | alr attached | 07:51 |
| davinci11 | as shown in hybridfox | 07:52 |
| flaccid | doesn't sound like the attachment was successful. | 07:52 |
| flaccid | if its not in fdisk -l or /dev/sdb it obviously didn't attach | 07:52 |
| davinci11 | should i change sdb to other ? | 07:53 |
| flaccid | you could try i guess | 07:53 |
| flaccid | and personally i wouldn't rely on hybridfox either | 07:54 |
| flaccid | though i wouldn't rely on eucalyptus at all :) | 07:54 |
| davinci11 | @@ | 07:54 |
| davinci11 | i tried /dev/vda | 07:55 |
| davinci11 | but.... in /dev | 07:55 |
| davinci11 | i found vdb | 07:55 |
| TeTeT | davinci11: check the instances disks with $ sudo fdisk -l - the one without partition table should be the volume | 07:57 |
| davinci11 | i attach /dev/vda again but this time show me vdc | 08:00 |
| davinci11 | when sudo fdisk -l | 08:00 |
| flaccid | yeah it won't be in fdisk -l anyway if not in /dev or /proc/partitions | 08:00 |
| davinci11 | Disk /dev/vdc doen't contain a valid partition table | 08:01 |
| flaccid | i'm not familiar with euca, but maybe try a xen virtual device such as /dev/xvdd | 08:01 |
| flaccid | davinci11: sweet it worked | 08:01 |
| flaccid | obviously you need to partition and format it to use it | 08:01 |
| flaccid | think of if like a blank hard disk you just bought from the store | 08:01 |
| davinci11 | why i put /dev/sdb(exercise) it never show up ?? | 08:02 |
| flaccid | well xen doesn't use /dev/sd* | 08:02 |
| flaccid | so if you are not using a kernel on the instance that has it patched to support /dev/sd* it won't work | 08:02 |
| flaccid | though i don't know how UEC/eucalyptus works in this respect with ubuntu EMIs etc. | 08:02 |
| davinci11 | TeTeT: $ euca-run-instances -t m1.large -k <KEY> <EMI> | 08:08 |
| davinci11 | Note: that the EMI used here cannot be the loader EMI provided in step 2. | 08:08 |
| flaccid | i still don't know what you are following. | 08:11 |
| davinci11 | the loader EMI on step2 is not real EMI right ? i tried to start it and try ssh but it wont work, so now i'm using intance downloaded from store | 08:11 |
| flaccid | smoser: is this on your blog or something? | 08:11 |
| flaccid | wtf is step2 | 08:12 |
| TeTeT | davinci11 + flaccid : I think the device id for euca-attach-volume was always only a hint, it could always be a differently named device | 08:12 |
| TeTeT | flaccid: it's from an exercise I handed over to him, http://people.canonical.com/~tspindler/UEC/ebs-based-instance.pdf | 08:12 |
| flaccid | oh right i referenced that earlier | 08:12 |
| * flaccid goes to read | 08:12 | |
| davinci11 | flaccid : LOL step2 is one of the exercise | 08:12 |
| TeTeT | davinci11: yeah, use one from the store or one from uec-images.ubuntu.com | 08:13 |
| flaccid | davinci11: learn to quote/reference resources so people know wtf you are going on about | 08:13 |
| davinci11 | flaccid ur words flaccid | 08:13 |
| davinci11 | watch ur words | 08:13 |
| * flaccid watches his words | 08:14 | |
| flaccid | davinci11: rght so i see no problem with that pdf. | 08:14 |
| flaccid | we can help if you cite the errors from the commands you are using | 08:14 |
| davinci11 | didnt u see i point to TeTeT: ? | 08:14 |
| flaccid | i.e. paste all teh commands and their response output on a pastebin otherwise we don't know where you failed | 08:14 |
| flaccid | no | 08:15 |
| davinci11 | no if just follow the pdf it wont work | 08:15 |
| flaccid | also note that a $() is a subshell so you won't see the output from whats in it, so its better to run it manually | 08:15 |
| flaccid | i will see if i can find a euca cloud | 08:16 |
| flaccid | TeTeT: can you help him out to try to get the commands run individually so the output is not in a sub shell, hidden. its bad scripting to assume a command in a sub shell will always work | 08:17 |
| davinci11 | see the step2 i mentioned above , pdf didnt tell beginner | 08:17 |
| davinci11 | and the how to ssh too | 08:18 |
| flaccid | yeah, i didn't make the pdf. i would of done some better error handling here | 08:18 |
| flaccid | hmm i've only got cloudstacks available atm sorry | 08:20 |
| flaccid | so every command that uses $(), run manually | 08:20 |
| flaccid | then if successful, assign it to the variable | 08:20 |
| flaccid | running in sh -x will also help | 08:20 |
| davinci11 | cloudstacks free ? may be i should try it later , after done with this UEC :P | 08:21 |
| flaccid | cloudstack and openstack both have free/oss versions | 08:21 |
| flaccid | RightScale also recently released myCloud though we are still in the transition to GA | 08:22 |
| davinci11 | great | 08:22 |
| flaccid | if you already have UEC setup, you only need to see why the commands are failing | 08:23 |
| flaccid | for example | 08:23 |
| flaccid | do this | 08:23 |
| flaccid | foo=$(echo bar) | 08:23 |
| flaccid | as you can see you won't see that echo because its in a sub shell. | 08:23 |
| flaccid | its also a good idea to learn sh/bash basics before using it. | 08:24 |
| davinci11 | so what should i type | 08:24 |
| davinci11 | echo bar ? | 08:24 |
| flaccid | arggh | 08:26 |
| flaccid | must be a language barrier here, not sure if i can help you sorry | 08:26 |
| flaccid | TeTeT: you wanna give it a try? this guy is always hard to help | 08:26 |
| TeTeT | flaccid + davinci11 : was afk. where are we at now? | 08:29 |
| flaccid | see scrollback | 08:33 |
| CloudAche84 | test | 08:40 |
| davinci11 | TeTeT: pls look pdf step 11 $ snapshot=$( euca-create-snapshot $vol | cut -f2 ) | 08:45 |
| TeTeT | davinci11: whats the output of euca-describe-snapshots? | 08:45 |
| davinci11 | TeTeT this step should create snapshot right ? | 08:45 |
| TeTeT | davinci11: yes | 08:46 |
| TeTeT | davinci11: and the snap id stored in snapshot variable | 08:46 |
| davinci11 | but in step 10 alr terminate instance so ..... | 08:46 |
| flaccid | good luck TeTeT | 08:46 |
| davinci11 | TeTeT : can still create snapshot ? | 08:46 |
| TeTeT | davinci11: did you create the volume the way it was meant to be? E.g. copied everything over? | 08:47 |
| davinci11 | yes | 08:47 |
| TeTeT | davinci11: so, is there a snapshot? | 08:48 |
| davinci11 | but in step10 it ask to detach volume | 08:48 |
| davinci11 | no snapshot | 08:49 |
| davinci11 | <TeTeT> : isnt it should snapshot while volume attached ? | 08:50 |
| TeTeT | davinci11: nope, you detach the volume and then create a snapshot | 08:50 |
| davinci11 | oh | 08:50 |
| davinci11 | instance need to terminate too ? | 08:51 |
| TeTeT | davinci11: doesn't really matter, but we don't need the utility instance anymore once the volume has been populated | 08:51 |
| davinci11 | euca-describe-snapshots | 08:53 |
| davinci11 | doesnt show anything | 08:53 |
| davinci11 | <TeTeT>: cant see in hybridfox too | 08:54 |
| TeTeT | davinci11: what's the content of $vol? | 08:54 |
| davinci11 | how to check ? | 08:55 |
| TeTeT | echo $vol | 08:56 |
| davinci11 | nothing | 08:56 |
| TeTeT | davinci11: so what's the output of euca-describe-volumes? | 08:57 |
| davinci11 | Volume vol-5A4C0637 1 cluster1 | 08:59 |
| flaccid | well echo "$vol" good idea to quote :) | 09:02 |
| TeTeT | davinci11: vol="vol-5A4C0637" | 09:03 |
| TeTeT | davinci11: and then try the snapshot creation again | 09:03 |
| TeTeT | flaccid: yeah, I usually don't specify the quotes in the exercises as any additional character leads to a chance a student mistypes it | 09:04 |
| flaccid | yeah though if the returns chars that need escaping, you need it e.g. [ or ] | 09:06 |
| flaccid | greybot: "USE MORE QUOTES!" They are vital. Also, learn the difference between ' and " and `. See <http://mywiki.wooledge.org/Quotes> and <http://wiki.bash-hackers.org/syntax/words>. | 09:07 |
| davinci11 | TeTeT: how long need to take to create snapshot, because my PC's led keep blinking i'm not sure snapshot still in progress | 09:11 |
| TeTeT | davinci11: check with euca-describe-snapshots | 09:12 |
| davinci11 | nothing | 09:12 |
| TeTeT | davinci11: weird, the command should return soon, though the snapshot creation can take some time | 09:13 |
| davinci11 | TeTeT: i know what is going wrong | 09:37 |
| davinci11 | TeTeT: $ snapshot=$( euca-create-snapshot $vol | cut -f2 ) | 09:38 |
| davinci11 | $vol should replace my own volid | 09:38 |
| davinci11 | now i can how much % | 09:39 |
| davinci11 | see | 09:39 |
| TeTeT | davinci11: ok, great to see progress | 09:44 |

| smoser | SpamapS, we should have redirected stderr to /dev/null on 'mkdir /var/run/network/static-network-up-emitted' | 17:50 |
| SpamapS | smoser: DOH I thought we did | 17:51 |
| SpamapS | smoser: I have another small change I need to push up. I assume it can wait until after A3 | 17:52 |
| smoser | you had it in yoru hunk but when we joined to the if we used mine which did not have it. | 17:52 |
| smoser | i think so | 17:52 |
| smoser | actually, yeah, it will never get seen | 17:53 |
| SpamapS | Probably only annoying messages on ifup at the cmdline | 17:53 |
| smoser | right? | 17:53 |
| smoser | as upstart output does not go anywhere | 17:53 |
| SpamapS | it goes where good log messages go to die | 17:53 |
| smoser | oh yeah, on ifup on the command line it would i htin | 17:53 |
