| Mrfai (~lange@suenner.informatik.uni-koeln.de) joined #fai. |
| 10:06 Winkie | so i was talking about installing ubuntu using a debian FAI server the other day, and i realised something |
| 10:06 Winkie | i've never done a FAI softupdate |
| 10:06 Winkie | and i don't know what the procedure would be with ubuntu installed |
| 10:06 Winkie | anyone want to enlighten me? |
| 10:06 mgoetze | i don't see why it should be any different than with debian |
| 10:06 Winkie | mgoetze: i don't even know how softupdates actually work :D |
| 10:08 mgoetze | on a server which was installed with fai and has a correct /etc/fai/fai.conf, you simply run "fai softupdate" and it will update the software, go through the scripts again, etc., so that, if you did everything right, you will end up with a system just like if you had installed it from the current configuration |
| 10:08 oz_ | ...just faster. |
| 10:09 mgoetze | and without significant downtime, generally |
| Action: oz_ really likes softupdates |
| 10:09 Winkie | ah i see, well i'll check it out once i've gotten the debian installation image booting on this machine |

| 11:12 edoreld | That worked ;) |
| 11:12 edoreld | used "grep -R "DHCPC" /srv/fai/config |

| 12:09 Winkie | bugger |
| 12:09 Winkie | well i got 2.6.29 booting |
| 12:09 Winkie | but looks like i should have included aufs with it |
| 12:09 Winkie | because it fails to mount with a no such device error |
| 12:09 mgoetze | yeah, you should :) |
| 12:09 Winkie | i used debian's 2.6.29 config :( |
| 12:09 Winkie | is there a fai config somewhere i can steal? |
| 12:09 mgoetze | it doesn't include aufs? if so, we'll have to file a bug report... |
| 12:10 Winkie | well, it might do, but the error i got was mounting aufs on /root failed: No such device |
| 12:10 Winkie | one second |
| 12:10 Winkie | debian-fai:/usr/src/linux# grep -i aufs .config |
| 12:10 Winkie | debian-fai:/usr/src/linux# |
| 12:10 Winkie | i'm going with no |
| 12:11 Winkie | ah, it's obviously not 'aufs' cause that isn't in 2.6.26 either |
| 12:11 oz_ | Winkie: you can alsoway use the simple examples in /usr/share/doc/fai-doc/examples/ |
| 12:11 Winkie | oz_: those are configuration files? |
| 12:11 oz_ | Winkie: If I would give you my config, I'd prolly get sacked from my job :) |
| 12:12 oz_ | Winkie: yes, those are config examples. |
| 12:12 Winkie | oz_: FAI configuration is not a problem, getting a working booting kernel is the problem |
| 12:12 Winkie | this machine will not boot on < 2.6.28 |
| 12:15 oz_ | so you need this kernel in the nfsroot and on the client. |
| 12:16 Winkie | yes |
| 12:16 Winkie | i'm building a defaulted upgrade from the 2.6.26 config now |
| 12:16 Winkie | lets see what happens |
| 12:16 Winkie | (in about an hour) |
| 12:17 Winkie | i only have a little under 6 hours to finish off here, and i've managed to do none of the tasks needed lol |
| 12:17 Winkie | ah well |
| 12:28 Mrfai | in Debian aufs is a seperate module. It's included in the package aufs-modules-2.6.26-2-486 and similar |
| 12:31 Mrfai | Winkie: I would try this: get the linux-image packages for 2.6.29 from sid, and also the aufs-modules-2.6.29.... package. add this kernel and auf-modules to your nfsroot, that should work |
| 12:32 Winkie | Mrfai: oh bugger it's a modules package? typical of me to miss that |
| 12:33 Winkie | i'm guessing it doesn't need to be in the initrd |
| 12:33 Winkie | cheers :) |
| 12:38 Winkie | haha Mrfai i need linux-latest-modules-2.6.29-2-686 apparently, which doesn't exist, don't you love computing |
| 12:39 Winkie | forced it through as that's a virtual package |
| 12:42 \sh | Mrfai: alaaf :) it's live-initramfs which adds the Debian Live Initramfs Hooks |
| 12:42 \sh | pool/main/l/live-initramfs/live-initramfs_1.156.1+1.57.1-1_all.deb (from latest lenny) |
| 12:44 \sh | Mrfai: btw..whoever is involved in setup_storage -> a big big hug from me it's much better then the old way |
| 12:49 Winkie | ah Mrfai it looks like aufs does need to be in the initrd |
| 12:50 Winkie | i've updated it with the module installed, lets see! |
| 12:50 Winkie | 00 |
| 12:51 Winkie | nop failure :( |
| 12:52 edoreld | I was gonna say 1000111 01101111 01101111 01100100 00100000 01101100 01110101 01100011 01101011 00100001 but I guess not -.- |
| 12:52 Winkie | haha sorry that was because i'm lagged as hell on this terminal |
| 12:52 Winkie | switching screens with ^A-0 :D |
| 12:52 Winkie | anyway now i need to figure out how to stuff aufs into this initrd |
| 12:54 Winkie | hahaha oh man |
| 12:54 Winkie | i got aufs loaded, and then got the exact same segfault i was having in ubuntu |
| Action: Winkie bangs head on keyboard |
| 12:55 Winkie | i'm going to have a nice drink and a sit down |
| 12:56 Winkie | i would really appreciate some advice on this, it was a known problem when i was talking about it yesterday, but i have no good solution if the debian version also segfaults :( |
| 12:57 \sh | Winkie: when I checked the source yesterday, there was one entry in /etc/fai/live.conf to be set...UNIONFS=aufs or something like this, dunno if this is right |
| 12:57 \sh | export UNIONTYPE="aufs" |
| 12:57 \sh | ah there it is...already set |
| 12:58 Winkie | \sh: i'm actually using Lenny, I guess maybe I should ugprade my boot environment to sid? |
| 12:58 Winkie | oh wait live.conf |
| 12:58 Winkie | i don't even have a live.conf :( |
| 12:58 \sh | Winkie: which version of FAI are you using?= |
| 12:58 Winkie | \sh: the default in Lenny |
| 12:58 Winkie | 3.2.17~lenny1 |
| 12:59 \sh | hmm |
| 12:59 \sh | 3.2.20 here...but I'm using FAIs archive from http://www.informatik.uni-koeln.de/fai |
| 12:59 Winkie | \sh: my problem is that i have these Dell Optiplex 320s, which require >=2.6.28 to boot |
| 12:59 Winkie | and so i've installed the sid kernel package (2.6.29) and aufs-modules for it |
| 12:59 Winkie | and i am getting the same segfault as i had when i tried to use ubuntu as a FAI base |
| 13:00 \sh | can you make a screenshot or something like that? |
| 13:00 Winkie | this is definitely a known problem, there were discussions on it yesterday, but I don't know where the problem occurs or what it encompasses |
| 13:00 Winkie | \sh: i can take a picture on my phone if you'd like? :) |
| 13:01 \sh | Winkie: I want to read the errors ;) sure :) |
| 13:02 Winkie | \sh: pm me your email address |
| 13:03 \sh | Winkie: no need to pm: sh@sourcecode.de :) |
| 13:06 Winkie | \sh: sending now |
| 13:06 Winkie | \sh: on ubuntu this occured every time on every boot on every machine |
| 13:06 Winkie | i have 3 (actually 4 but the fourth is irrelevant) different machines i'm trying this on, only one needs 2.6.28 but it seems wise to try and use it everywhere |
| 13:10 Winkie | right well email should have been sent |
| 13:10 Winkie | i know that the ubuntu CD version boots fine, so i'm reasonably sure it's an aufs bug of some sort, but god knows what |
| 13:10 Winkie | let me find my logs from yesterday |
| 13:11 Winkie | haha oh it was you talking :) |
| 13:11 Winkie | excellent |
| 13:12 \sh | https://bugs.launchpad.net/ubuntu/+source/linux/+bug/382842 |
| 13:13 \sh | I think that this bug report is important here ;) |
| 13:14 Winkie | perhaps, although this is an actual panic i think. did you get my email? |
| 13:14 \sh | yepp |
| 13:15 Winkie | excellent, out of interest did it come from my mob@gmail account? |
| 13:17 \sh | Winkie: the bug and your crash could be related (ubuntu wise) |
| 13:17 \sh | Winkie: I would like to test it myself...but I won't come to the point of testing until next week... |
| 13:18 Winkie | \sh: it's possible, i could look at attempting to upgrade aufs myself, if there's anything i can do to give you access to help me out let me know |
| 13:18 Winkie | you're welcome to have SSH access to the virtual environment i'm preparing this on |
| 13:19 \sh | Winkie: no need...I just have enough hardware to test...I only need to setup an ubuntu box with fai ... that's straight forward...but my time is limited today and tomorrow |
| 13:19 Winkie | i see, well thanks for the help anyway, i've been waiting months for ubuntu to even boot on these machines so a few more days won't hurt, i'm just in the office today so hoped to get it finished |
| 13:20 Winkie | i'll see if i can update aufs and recompile a module for it |
| 13:20 Winkie | not done that with debian's build system before |
| 13:29 edoreld | Winkie are you trying to install ubuntu from debian fai-server? |
| 13:30 Winkie | edoreld: ideally yes, but i haven't gotten as far as debian booting and installing debian yet |
| 13:32 edoreld | Winkie: ouh |
| 13:32 edoreld | Winkie: just wanted to know the quirks & twists of what booting ubuntu from debian require ^^ |
| 13:33 Winkie | edoreld: i'm not actually booting ubuntu, i'm booting debian and then going to copy a ubuntu bootstrap to the hard drive i think |
| 13:35 edoreld | aah yeah that sounds easier :) |
| 13:53 Mrfai | \sh: you mean live-initramfs_1.156.1+1.57.1-1_all.deb is needed to fix the problems you described in your mail? But this version is already in lenny, so IMO I do not need to add this into my repository |
| 13:54 \sh | Mrfai: no...it's the package to be fixed :) the patch mentioned by Carsten needs to go in |
| 13:55 \sh | BBL...TTBB: 2h |
| 13:56 Winkie | Mrfai: any immediate suggestions for me? ;) |
| 13:57 Mrfai | Winkie: no panic |
| 13:57 Mrfai | ;-) |
| 13:58 Winkie | Mrfai: that could mean "panic" or "don't panic" :( |
| 13:58 Mrfai | I would try to boot your machine using the debian kernel and aufs from Debian sid. |
| 13:58 Mrfai | don't panic ;-) |
| 13:59 Winkie | Mrfai: that's exactly what i did, and it panics :) |
| 13:59 Winkie | i sent the images to \sh but i'll upload them, one minute |
| 14:01 Mrfai | Winkie: did you every tried this with some other piece of hardware? |
| 14:02 Winkie | Mrfai: i did not, but this crash is exactly the same as i got using ubuntu's fai-server and i did try that on other hardware, would you like me to go and test this version on other hardware too? |
| 14:06 Winkie | Mrfai: http://i42.tinypic.com/14jx0r9.jpg http://i40.tinypic.com/2gtd75j.jpg http://i43.tinypic.com/291ynty.jpg |
| 14:06 Mrfai | this is up to you. I don't have the overview which fai version you are using exactly. |
| 14:06 Mrfai | IMO there are two possiblilities |
| 14:06 Mrfai | 1) your hardware and the new kernel causes the kernel panic |
| 14:07 Mrfai | 2) the new kernel and aufs is brken on all hardware |
| 14:07 Winkie | Mrfai: i'm using the lenny default version, which is 3.2.17~lenny1, with a 2.6.29 kernel from debian sid |
| Action: Mrfai must go to a meeting |
| 14:07 Mrfai | now |
| 14:07 Winkie | i'm thinking #2 also |
| 14:07 Winkie | thanks for your help |

| 15:21 Winkie | mgoetze: i am no fai expert, but i can't see anything obvious there, there are all sorts of possibilities for why icecast might be failing to start, have you considered modifying the init file to write logs somewhere / does it write logs by default? |
| 15:23 oz_ | I wonder why the output is so mangled... |
| 15:23 oz_ | and I remember icecast being a bitching piece of software in regard to restarts and so |
| 15:39 mgoetze | yes, in fact i generally do ... stop; ... start rather than restart... maybe i should just rewrite the init script |
