| 13:17 nocturn | Hi guys |
| 13:17 nocturn | I'm trying to deploy FAI for a BEOWULF cluster (on Debian Etch) |
| 13:17 nocturn | But I have two kinds of nodes, one 64-bit, the other 32-bit. How do I handle this best with FAI? |
| 13:22 stockholm | have two classes? |
| 13:23 nocturn | stockholm: With two NFSRoots? |
| 13:23 stockholm | nocturn: yes, i would think so |
| alexanderwz (~alexander@karuna.med.harvard.edu) got netsplit. |
| alexanderwz (~alexander@karuna.med.harvard.edu) returned to #fai. |
| 13:35 nocturn | How do I make the 64-bit NFS-root and kernel image on an 32-bit FAI server? |
| 13:36 Mrfai | this is not possible |
| 13:36 Mrfai | but you can make a 32bit nfsroot on a 64bit server |
| 13:37 Mrfai | I think there's something written in the faiwiki on that topic |
| 13:40 nocturn | I can't find an article on this... |
| 13:40 nocturn | I know it can be done, though it's possible that make-nfsroot was run on an 64-bit machine over NFS |
| 13:41 nocturn | I have an existing cluster here deployed that way, though I do not know how it was set up. |
| itais (~itais@62.81.119.138.static.user.ono.com) left irc: Quit: See you |
| 13:46 Mrfai | running make-fai-nfsroot on a 64bit machine and using a directory that is NFS mounted from a 32bit machine is also a good solution. |
| 13:47 nocturn | Thanks, we'll go that route I guess |
| 14:04 lazyb0y | Mrfai: yes, maxpackages does it... any reason why this isn't used by default? |
| 14:05 Mrfai | IMO it takes much longer when using MAXPACKAGES=1. Can you please compare the time of calling fai-mirror with and without setting it. |
| 14:06 MT | Mrfai, didn't we have this setting at some point? |
| 14:06 MT | after all, it is fine to have confilicting packages in the mirror... |
| 14:06 lazyb0y | i didn't measure this run I did now, but from the feeling it's not much more - in both cases about 5-10 minutes, while the real reporistory is on the local machine |
| 14:07 lazyb0y | or maybe 5-15 |
| 14:07 lazyb0y | for a mirror that is finally about 1GB |
| 14:08 lazyb0y | (running fai-mirror with time now...) |
| 14:12 lazyb0y | BTW another thing I realized is, fai-mirror will not work well if I have an infrastructure where different systems (e.g. test and production, etch and sid) have different sources.lists |
| 14:14 lazyb0y | so currently this can only be solved by having multiple fai configdirs and point fai-mirror to that |
| 14:15 lazyb0y | I think, it's acceptable to say people need to build different cd's for systems with different sources.list's, but fai-mirror should also accept an extra sources.list as parameter. |
| 14:15 lazyb0y | or is that a much more compley topic? |
| 14:18 lazyb0y | done with the fai-mirror with maxpackages |
| 14:18 lazyb0y | time: 9 minutes for a mirror of 1.6 GB |
| 14:19 lazyb0y | I'm not going to measure the cal wihtpout again, I am sure it was not much faster - even if it only had 1.1 GB, probably because of the errors |

| 14:44 Mrfai | lazyb0y: fai-mirror for the simple examples. Using my local mirror. this creates a partitial mirror of 454MB. |
| 14:44 Mrfai | MAXPACKAGES=1 => 2min 26 |
| 14:44 Mrfai | MAXPACKAGES=9999 => 1m22 |
| 14:45 Mrfai | and if you specify -v you will get a lot more output when setting the variable to 1. |
| 14:45 MT | and, well, is the mirror the same size? |
| 14:45 Mrfai | yep. Same size in MB, I did not checked all packages |
| 14:46 MT | ok, so there is some (obvious ...) overhead |
| 14:46 MT | but the MAXPACKAGES=1 mirror is surely complete, the other may be broken |
| 14:46 Mrfai | if your internet connextion is slow(er) then it does not count, because downloading takes more time |
| 14:48 lazyb0y | Here, I work with a bigger mirror, and then, the difference is not as much as there |
| 14:48 lazyb0y | and my connecttion here is very fast, it's the same machine |
| 14:52 lazyb0y | measuring the normal call now |
| 14:52 Mrfai | difference in packages with simple example is only one package: inetutils-ping. It's missing when using MAXP...=9999 |
| 14:53 lazyb0y | anyway, the questions is: is this increase in runtime worth the fact that users who run into this problem will not easily find the problem and the solution? |
| 14:53 lazyb0y | Mrfai: you mean, even with the simple examples your mirror is incomplete? |
| 14:54 lazyb0y | BTW, my guess was wrong - it takes only 2m23 |
| 14:54 lazyb0y | still, creating something broken fast does not really count as "better" :) |
| 14:55 lazyb0y | (and there are 500MB of packages missing!) |
| 14:58 Mrfai | ok, I will set MAXPACKAGES=1 in fai-mirror. |

| 19:11 Barbarossa | Warum geht install_packages nicht, wenn es chrooten soll, aber läuft, wenn ichs per Hand im chroot starte? |
| 19:11 Barbarossa | Das Problem scheint zu seien, dass er im Chroot keine "Debian Package Index" findet sondern nur dpkg-foo |

| 19:24 stockholm | vielleicht liest er es dann |
| 19:25 Barbarossa | Mrfai: *stubbs* |
| 19:27 Barbarossa | stockholm: Hast Du schonmal mit dem AptPkg::* Kram gearbeitet? |
| 19:31 stockholm | Barbarossa: nee |
| 19:31 stockholm | wozu braucht man das? |
| 19:31 Barbarossa | Scheiss amd64 Karren |
| 19:31 Barbarossa | Das benutzt FAI um zu checken ob die Pakete, die in package_config/* angegeben wurden da sind. |
| 19:32 Barbarossa | Wobei ich mich frage waurm man nicht einfach apt-get aufruft und guckt obs knallt. |
| 19:32 Barbarossa | Dann hätte ich dieses Problem nicht |
| 19:33 Barbarossa | Die alles entscheidende Frage ist, warum ich keinen 'Debian Package Index' habe |
| 19:33 stockholm | apt-get im chroot ausführen? |
| 19:33 stockholm | apt-get update |
| 19:33 Barbarossa | Das macht das Ding ja |
| 19:33 Barbarossa | Nur leider funktioniert das nicht |
| 19:34 Barbarossa | Nehmen wir mal die Checks raus. |
| 19:34 Barbarossa | Die Pakete gibts ja schliesslich |
| 19:34 stockholm | :-) |
| 19:35 Barbarossa | schaunwamal |
| 19:36 Mrfai | verstehe das Problem nicht. Package Index klingt nach Packages.gz. Vielleicht ist die sources.list falsch. |
| 19:36 Barbarossa | nein |
| 19:36 Barbarossa | Wenn ich per Hand nen chroot mache und dann apt-get isntall list_der_pakete mache tut alles |
| 19:37 Barbarossa | in install_packages guckst Du ja im apt-cache nach ob das Pakete da ist. |
| 19:37 stockholm | kannst du ins generierte chroot reinchrooten und da apt-get machen? |
| 19:37 Barbarossa | ja |
| 19:37 Barbarossa | sag ich ja |
| 19:37 Barbarossa | Und Du machst sowas: return 1 if ($fitem->{File}{IndexType} eq "Debian Package Index"); |
| 19:37 Barbarossa | Allerdings steht da bei nicht Debian Package Index dron sondern was mit dpkg |
| 19:37 Mrfai | wenn du aptitude statt apt-get nimmst (im package_config) dann wird nicht ueberprueft ob das Paket existiert. |
| 19:38 Barbarossa | Ich habs jett auskommentiert... |
| 19:38 Mrfai | Barbarossa: nimm einfach aptitude statt install hinter PACKAGES |
| 19:38 Barbarossa | in der package_config? |
| 19:38 Barbarossa | ok das ist natürlich noch einfacher |
| 19:38 Barbarossa | probier ich gleich mal |
| 19:40 Barbarossa | ok nen 64bit kernel wäre jetzt noch gut gewesen ;) |
| 19:46 Barbarossa | Warum hat der lilo nicht installiert? *wunder* |

| 20:08 Barbarossa | eth0 und eth1 sind ja da. Nur falsch rum ... |
| 20:08 stockholm | ahh, ätzend. |
| 20:08 Barbarossa | Ich *HASSE* udev |
| 20:08 stockholm | Barbarossa: am einfachsten ist umstöpseln |
| 20:08 Mrfai | liegt daran das der kernel eine andere reihenfolge hat als PXE boot. |
| 20:08 Barbarossa | stockholm: geht nicht. |
| 20:08 Barbarossa | Das ist nen Blade. Das kann ich einfahc nur 'reinstecken' |
| 20:08 stockholm | Barbarossa: kannst du eine im bios abstellen? |
| 20:09 Barbarossa | Will ich nicht. |
| 20:09 Mrfai | hilft nur bei PXE, der kernel wird imme rbeide sehen AFAIK |
| 20:09 stockholm | kannst du das netzwerkbooten bei der einen abstellen? |
| 20:09 Barbarossa | beim booten ists ja richtig |
| 20:09 stockholm | ah |
| 20:09 Barbarossa | FAI nimmt auch die richtige |
| 20:09 Barbarossa | Die anderen ist nichtmal konfiguriet |
